PREFACE

IN this edition the work is completely revised, and as far as possible brought up to date. The most noteworthy new feature is the incorporation of all the parts into one general dictionary, and the omission of Part I of previous editions. When first written this had certain advantages, as being one of the few presentations in English of the ele- mentary facts and theories of ecology. But this advantage has long disappeared, and it seemed to me that the space would be better employed in increasing the number of genera dealt with. On consulting Sir David Prain and other bota- nists, I found that they agreed with this idea. By a slight addition to the total number of pages I have found it pos- sible to include all the genera, and hope that in this way the usefulness of the work to botanists in general may be greatly increased. I have of course attempted no criticism of those included, but have tried to indicate, as far as space would permit, the genera from which they have been segre- gated in many cases, or to which they are united by the other of the two chief recent editors of the vegetable kingdom (Bentham-Hooker, Engler-Prantl). It is obviously impossible to do very much in this direction. As it stands, the book is convenient for use, but a very slight addition to the facts given for each genus would add a line to the entry and, as there are roughly some 20,000 entries, this would add 400 pages to the book, and make it unwieldy. The same remark applies to the geographical distribution, which could not in general be given in great detail.

Before criticising, again, the inclusion of many obsolete technical terms and synonyms, it must be remembered that

o I

vi PREFACE

some who use this book wish to use it in connection with floras now long published, and also that it is impossible to reset such a book all through for each edition, so that it is necessary to insert a little "padding" on practically every page.

Ecological, morphological, and other subjects have been dealt with by giving comparatively full accounts under se- lected genera. By referring, first to the subject, e.g. to Adventitious Buds, and then to the genera mentioned there, e.g. Begonia, Bryophyllum, &c., a fairly detailed account of each subject may be put together. In using the book, the subjects mentioned under a genus should always be looked up, to find other examples, e.g. under Aesculus look up Bud, Leaf, Leaf-mosaic, Cincinnus, Dichogamy, Change of Colour, >S:c. A book like this must obviously be a compilation, and I have to express my warmest thanks to Prof. A. Engler for permission to draw upon the vast mass of material con- tained in Die Natiirlichen Pflanzenfamilien. Owing to the war I have had no opportunity of asking him to renew this permission, and I trust that he will understand as much. When an article, as is frequently the case with the grouping of the sub-families within the family, is taken from the work mentioned, I have acknowledged the same by giving the name of the author. Otherwise I have in general: drawn upon the book for the genera accepted by its authors, for the number of species (which has been brought roughly up to date by aid of the Supplements to the Index Kewensis), and for their geographical distribution.

The list of friends to whom I owe valuable suggestions, useful pieces of assistance, and the like, is very long, and I have no doubt that the following enumeration is incomplete, and must ask the pardon of those who do not figure in it, through some oversight on my part to note down their names at the moment the help was given. In the first place

PREFACE vii

I wish to thank Sir David Prain and the staff at Kew, more especially Drs Hill, Stapf, and Rolfe, and Mr S. A. Skan, whose detailed knowledge of the library has been of the very greatest assistance in easing my labour. The writing of this edition has occupied very much time during the last five years, and I am particularly grateful to Prof. Seward, who placed at my disposal a table large enough to enable me to spread out 20 works of reference at once, and to Dr Moss and others of the Cambridge staff. The first two of the five years were spent in Rio de Janeiro and I am much indebted for help to my colleagues there, particu- larly the late Dr Alberto Lofgren and Dr Achilles de Faria Lisboa. I also owe many useful suggestions to my col- leagues in other Botanic Gardens, e.g. Prof. O. Ames at Harvard, Prof. I. B. Balfour at Edinburgh, Prof. N. L. Brit- ton at New York, Mr I. H. Burkill at Singapore, Prof. A. Engler at Berlin, Dr J. H. Maiden at Sydney, the late Dr H. H. W. Pearson at Cape Town, Dr Sargant at Jamaica Plain, and others. The late Dr E. A. N. Arber, and Mrs Arber, have laid me under very many obligations, and so have Sir Francis Darwin, Professors Bower, Farmer, Goebel, Goodale, Henry, Lang, Oliver, Scott, and Yapp, and Messrs Davie, Lock, Lynch, Riddle, Small, Smith, and many more. To my wife my obligations are unmeasured. Finally for the illustrations I have to thank Herr Engelrnann for permis- sion to copy some of the late Prof. Eichler's figures, and Dr Rendle for the use of some of those in his book on Classification.

EXPLANATORY INTRODUCTION

The Index of English names, technical terms, &c., which formed Part III of former editions, is now incorporated with the list of genera, so that the work forms one dictionary from end to end, with the exception of the key to the families at the end of the book.

All the genera of Bentham- Hooker, Engler-Prantl, and Linnaeus are now included, as well as all given in the Index Kewensis and Supplements (except many synonyms), together with a large number published since the last Supplement, and which, by the kindness of the Director of Ke\v, I have been able to obtain from the MS lists kept at Kew. The most recent of these are given in a little Supplement at the end of the main dictionary, and I hope to bring this supplement up to date at intervals during the currency of the edition, adding the entries later to the body of the work so far as the padding will allow. Besides the genera, all families and higher divisions are also included.

The name of the genus is followed by the name of its author, often abbreviated, e.g. R.Br. (cf. Abbreviations), on the system explained under Nomenclature. The original description of the genus may be found by reference to the Index Kewensis. In the same way, the author is given after every species quoted, and the original description may be discovered from the same book.

Owing to the continual changes that go on in many families and genera, names are often reduced to synonyms; a great number of such are given in this book, chiefly those used in well-known floras; e.g. Abildgaardia Vahl = Fimbristylis Vahl. Under some of the best known genera, e.g. Abies, a few specific synonyms have also been given, especially names frequently met with in gardens, and opposite to each of these is given the name now generally used; thus Abies alba Michx. must be looked for under Picea, Abies Douglasii Lindl. under Pseudo- tsuga, and so on. It is very difficult to decide when divergence of two forms is sufficient to entitle them to rank as genera, and this difficulty is the cause of much synonymy. A genus A is established by one author, and then it is discovered not to differ sufficiently from another genus/?, established by the same or another author, to remain as an independent genus. A is therefore merged in B and becomes a synonym. The

x I NTH OD UCTION

species of A retain as far as possible their old specific Qames when placed in B. When an entry such as " Abildgaardia Vahl = Fimbri- stylis Vahl p.p." is found, it means that the genus Abildgaardia as established by Vahl is merged in his Fimbristylis. Many of the species change their names, but some retain their specific names, when the name is not already occupied. This latter case is often indicated by putting the name of the old genus in brackets after that of the new, thus, F. (A.) fulvescetts. In many cases the names of some of the genera thus merged in other genera are indicated thus: Axinandra Thw. (BH. inch Naxiandra Krasser) ; no attempt however has been made to give all such cases or a fraction of them, but only a few of the more im- portant. In particular those have been given where the genus as here defined differs from the definition in Engler and Prantl's Natiirliche Pfianzenfamilien or Bentham and Hooker's Genera Plantarum by the inclusion and exclusion of other genera.

The name of the genus is followed by that of the family to which it belongs, and after this is often a number (in brackets) indicating the section of the family, thus Acacia belongs to Subfamily I and Tribe 2 of Leguminosae. The general plan upon which the book has been con- structed, and the necessity for condensation, render it essential, if the full advantage is to be derived from its use, that the student should refer to the family as well as the genus. There he will find the important general characters possessed by its members, and should examine the genus to see in what it agrees, and in what it disagrees, with these. A further reference to the classification given at the end of the article upon the family will point out the special characters to be looked for in the genus as a member of some particular sub-family or tribe. In this way a large amount of information about the particular plant in question may be obtained, and at the same time the student will get into the way of regarding plants not as so many independent and disconnected units, but as related members of one great whole. In this way too he will soon acquire an appreciation of the relative importance of the different characters in classification and will learn to recognise the approximate relationships of most plants after a brief inspection, or even at sight.

The families are those given by Engler in his Syllabus and in Die natiirlichen Pflanzenfamilien, but sufficient reference is made to Bentham and Hooker's system of classification to enable any one who may prefer to use that system to do so.

The name of the family is followed by a statement of the number of

INTR OD UCT1ON xi

species in the genus, and its geographical distribution. The number, unless very small, is always only an approximation ; new research is always bringing new species to light, splitting up older ones, or com- bining two or more into one. This is all the information that is given about a very large number of the genera ; only when a genus presents some character of interest which is not common ta the order or group, is any particular mention made of it. The biological peculiarities of the most important genera are dealt with pretty fully, but much has been omitted. Thus in dealing with the pollination-methods of flowers a selection of important genera, illustrating the various methods, has been made for description ; so too with epiphytes, xerophytes, the morphology of parts, and so on. General discussions of all these subjects will be found under the title of the subject itself, and numerous examples are there quoted; these examples are mostly dealt with more fully. Numerous cross-references to other articles, e.g. Buds, Dichogamy, Fruit, Leaf, Parasite, Xerophyte, &c. (cf. Index), are made, and should be looked up.

While in the morphology, &c. a selection has thus been made of genera for treatment, this is less the case with economic botany. This has been more fully treated, only a comparatively few genera being omitted. Space, however, has not permitted of a detailed description of economic products or the way in which they are obtained ; for this reference must be made to other works (see Literature).

Turning now to the other articles upon the families, the same general principles apply to them. After the name of the family is given the order to which it belongs, marked EP. or BH. if necessary to distinguish between these systematists. This should be looked up in the key at the end ; this will show the families which are most nearly related to the one under consideration, and the characters that distinguish one from the other can be made out by comparison of their descriptions. The student should always endeavour to make out why a given family is classified in the position assigned to it. When the family as defined by Engler differs from that defined by Bentham and Hooker, as is so often the case, an attempt should be made to discover the reasons for the difference.

After the position of the family in the system follows the number of its genera and species, the morphology and natural history of its vegeta- tive and reproductive organs, its economic products, and finally, in the case of the more important families, its classification into sub-families and tribes, with the more important genera belonging to each. The student should work through this part and study as many of the genera

xii INTRODUCTION

as possible before leaving the family. This is easily managed in dealing with the outdoor collection in our botanic gardens.

No particular attempt is made in the book to avoid technical terms. When a term or abbreviation is used that the reader does not understand he should look it up in the Dictionary, or under Abbreviations.

To save space, in many cases in which there are several words in use beginning with the same prefix, e.g. aniso-, apo-, endo-, epi-, geo-, gyno-, halo-, heter-, iso-, phyllo-, poly-, sym-, xero-, &c., all are given under the heading of the prefix. If a word is looked up as a whole, there- fore, and not found, reference should be made to the prefix before saying that it is omitted from the Dictionary.

Many genera are described by different authors under different spellings, and the most common and important of such cases are in- cluded ; thus Prunella is also described under Brunella, Eleocharis also under Heleocharis, £c.

Abbreviations. Descriptions of floral morphology are largely given in the terms of Floral Formulae, explained under that heading. When the name of a genus or family is repeated in the article dealing with it, it is represented by the initial letter only, e.g. A. for Abies. The name of a family is sometimes abbreviated by the omission of the terminal aceae, &c. ; e.g. Capparid., Compos. The term 'warm' is sometimes used instead of 'tropical and subtropical.' The expression BH. after a genus or family, &c., means "as defined by Bentham and Hooker in their Genera Plantaruni " ; EP. means "as defined by Engler and Prantl in the Pflanzenfamilien and Pflanzenreich"

No short shoots. On the main stem the symmetry is radial, whilst on

the horizontal branches the 1. twist so as to get their surfaces all much

in one plane. If the top bud or leader be destroyed, however, a branch

bud below it takes up the vertical growth and radial symmetry. Cones

vertically — this exposes less surface to radiation. A mere inspection, though it shows the phyllode to he a leaf-structure (it has an axillary bud), does not show that it is not a 1. turned edgewise, though it shows no twist at the base. Occasionally however there are reversions to type (i.e. to the ancestral form) on the plant, some phyllodes occurring with leaf-blades of the ordinary bipinnate type. This is still better seen in germinating seedlings. The first 1. are typical bipinnate 1., followed by others with slightly flattened stalks and less blade, and so on, until finally only phyllodes are produced. In A. alata R.Br. and others, the phyllodes are decurrent on the stem, like the 1. of thistles. In many the slips, are repres. by large thorns, swollen at the base. In A. spkaerocephala Cham, et Schlecht. (Cent. Am.), the thorns are inhabited by colonies of ants, which bore into them and clear out the internal tissue. The ants live on the A. and are fed by it. Extrafl. nectaries occur on the petioles, and yellow sausage-shaped food-bodies on the tips of the leaflets. These consist of parenchymatous cells containing food -st lifts, and are eaten by the ants. If attempt be made to interfere with the tree the ants rush out. (Cf. Cecropia, and see Nature, Aug. 1893, for an account of the leaf- cutting ants: and cf. Schimper, Plant Geogr. p. 140. This was the first case of myrmecophily (symbiosis with ants) discovered; see Belt's Naturalist in Nicaragua.) Other sp. are myrmecophilous also. A few are twiners, others hook-climbers. Most are xerophytes, often forming char, features in vegetation and scenery, e.g. the babul (A. arabica Willd.) with its low, spreading habit, is almost the only tree in many parts of the dry plains of India, and others are common in S. Afr. &c. In Austr. (esp. S. Austr.) the A. take a great part in the formation of the scrub, a concourse of shrubby plants of many genera, which covers the almost waterless country with a waste of veg. about 6 — 10 feet high, of a general bluish green effect, and with few herbs or grasses beneath.

The fl. (diagram, see order) has oo long sta. , affording little pro- tection to the pollen. In A. hotnalophylla A. Cunn. (S. E. Austr.; Myall) the seed hangs out on a long red funicle.

Many valuable products. A. Senegal Willd. (Soudan) yields the best gum-arabic; the gum exudes from the branches principally during the prevalence of the dry desert winds. Other sp. yield inferior qualities. A. catechu Willd. (E. Ind.) yields catechu orcutch (used in tanning), by digestion of the wood in hot water. With this the true khaki cloth is dyed and shrunk. A. decnrrens Willd. (Austr. ; black wattle) yields good tan bark; inferior barks from A. pycnantha Benth. (S. E. Austr.; golden wattle), A. dealbata Link (Austr.; silver wattle) &c. That of A. arabica Willd. is largely used in India. The wood of many is valuable, esp. Australian black-wood, A. mclanoxylon R.Br. Many have sweetly scented fls. ; those of A. Farmsiam Willd. (trop.) are the Cassie flowers of perfumery. A. annata R.Br. (temp. Austr.; kangaroo thorn), A. horrida Willd. (S. Afr.) &C. form good hedges or sandbinders.

The anthers form a box by fitting closely together at the sides, and shed their pollen sideways into it, where it is held by hairs till an insect probing for honey forces the filaments of the sta. apart and receives a shower of pollen on its head (loose-pollen mechanism, cf. many Scrophulariaceae, Ericaceae, &c.).

Trees and shrubs, with opp. exstip. 1., deciduous or ever- green. L. often simple entire, more commonly 3- or 5-lobed, occa- sionally cpd. One may go through a collection of A. in an herbarium or elsewhere, comparing the 1. as to degree of development of the drip-tips (acum. apices to easily wetted 1., from which the water drips off rapidly after a shower, cf. Ficus) noting the kind of climate from which each has come. There is a correlation between length of tip and wetness of climate.

Large winter buds, covered by scale 1. In many sp. transitional forms may be seen as the bud elongates in spring, between the scales and the green 1., showing that the scale = not the whole 1, but the leaf base. In the § Negundo there are no scales, but the bud is protected by the base of the petiole of the 1. in whose axil it arises.

The 1. commonly exhibit varnish-like smears, of sticky consistence, known as honey-dew, the excretion of aphides which live on the 1.; the insect bores into the tissues, sucks their juices, and ejects a drop of honey-dew on an average once in half-an-hour. In passing under a tree infested with aphides one may sometimes feel the drops falling like a fine rain (see Pithecolobium). The fluid is rich in sugar. When the dew falls the hygroscopic honey-dew takes it up and spreads over the 1. ; then later in the day evap. reduces it to a varnish on the surface. Many other trees exhibit this phenomenon, e.g. lime, beech, oak (Btisgen, Der Honigthau, Jena).

L. or segments not even meeting at edges, the a. is open (C of Cruciferae, see floral diagrams), touching but not overlapping, valvate (C of Compositae), overlapping, imbricate (K of Leguminosae). Special cases of imbr. are convolute or contorted (each 1. overlapping with the same right or left edge, so that the C looks twisted, as in Ericaceae) and qtiin- cttncial (two 1. overlapping with both edges, two underlapping with both, one over- and under-lapping, as in K of Caryophyllaceae). Each 1. overlapping the one post, to it, ascending (K of Vicia in Leguminosae), ant. to it, descending (C of Vicia). L. margins turned inwards, indnplicate (C of many Compositae), outwards, reduplicate. L. rolled up inwards like watch springs, circinate (petals of Hama- melidaceae).

Agave L. Amaryllidaceae (n). 100 trop. Am. and S.U.S., incl. A. americana Linn. (Century plant, Maguey, American aloe). The short stem grows in thickness like Yucca, bearing a rosette of large fleshy 1. coated with wax; only 2 or 3 1. form in a year. During 5 to 60 or perhaps 100 years (hence the name), depending on climate, richness of soil, &c. , the plant is veg. , and stores up in the 1. an enormous mass of reserves. At length it flowers, a gigantic term. infl. coming rapidly out, sometimes reaching 20 feet, and bearing many fls. When the fr. is ripe the pi. dies. Veg. repr. in two ways — by suckers from base of stem, and by formation of bulbils in place of many fls.

The rush of sap to so large and so rapidly developed an infl. is very great ; the Mexicans cut off the young fl. head and collect the sap. As much as rooo litres are said to be given by one plant. The fermented juice (pulque) is a national drink; from it they distil a spirit called mescal (cf. Cocos). Many yield useful fibres. The best are sisal hemp and henequen, given by A. sisalana Perrine, and A. fourcroydes Lem., cultivated in Yucatan, the Bahamas, India, &c. Others yield fibres variously known as pita, istle, ixtle, lechuguilla, keratto, &c. See Rep. Miss. Bol.

Angiospermae. One of the two great divisions of Spermaphyta, dis- tinguished from Gymnosperms by the fact that the cpls. are so infolded or arranged as to form an ovary in which the ovules are borne. Endosperm formed after, instead of before fert.

All A. possess true fl., the essential parts of which are sta. and cpls. The former bear pollen-sacs ( = microsporangia of Pteridophyta), the latter ovules (megasporangia). The ovule is always enclosed in the cpl. ; it has two (or one) integuments, and usually one embryo- sac (more in some chalazogamic forms, Loranthaceae, &c.). The pollen-tube may enter by the micropyle or by the chalaza (cf. Chala- zogamae). Parthenogenesis, or development of the ovum into an embryo without fert., occurs in Antennaria, Akhemilla, Hieraciiim, Houttttynia, Thalictrum, IVikstroeiuia, &c., embryo formation by adv. budding in Alc/tornea, Citrus, Euonymus, Funkia,Nothoscordum, &c., apogamy (cf. Filicineae) in Balanophora.

A. are divided into Mono- and Di-cotyledons (cf. classification at end of the book).

Many types of veg. habit— herbs large and small, with aerial stems, tubers or rhiz., climbing shrubs, climbing epiph., marsh pi., one water pi. (Pistia) &c. In a few Pothoideae the stem is monopodial, but in most A. it is sym- podial. Each joint of the sympodium begins as a rule with one or more scale 1. before bearing fol. 1. Accessory (collateral) buds often found in the leaf axils. Sometimes, as in Anthurium, Philodendron &c., the axillary shoot is ' adnate ' to the main axis for some distance (cf. Solanaceae, Zostera &c. ). The buds usually appear in the 1. axils, but often get pushed to one side, and sometimes (e.g. Pothos) break through the leaf-bases as in Equisetum.

Roots adv. and mostly formed above ground in the larger forms. Two types of aerial r. — climbing and absorbent. The former, like ivy, insensitive to gravity, show great negative heliotropism ; they cling closely to the support and force their way into the crevices. The latter, insensitive to light, respond markedly to gravity ; they grow down to the soil and enter it, branching out and taking up nourishment.

The larger trop. A. show interesting stages in the development of epiphytism. The climbing forms grow to considerable size and form longer and longer aerial r. as they grow upwards. The original r. at the t.ase thus become of less and less importance and they often die away together with the lower end of the stem, so that the plant thus becomes an epiph. Of course, as it still obtains its water &c. from the soil, it is not an epiph. in the sense that e.g. many Orchids or Bromeliaceae are such, and it is evident that if this method of becoming epiph. were the only one found in the order, these plants could with no more justice be classed as true epiph. than the ivy which may often be seen in the ' bowls ' of pollard willows in Europe, and which has come there by climbing up the trunk and dying away below. It is found however that some sp. of Fhilodendron, Pathos, &c. are able to commence life as epiphytes. The fleshy fr. is eaten by birds and the seed dropped on a lofty branch. The seedling forms clasping r. and dangling aerial r. which grow steadily down to the soil, even if it be 100 feet or more away. It is hardly possible to suppose that these true epiph. sp. have been evolved in any other way than from former climbing sp. Lastly, some sp. of Anthurium &c. are true epiph. without connection with the soil (e.g. A. Hiigelii Schott = A. Hookcri Kunth.) ; they have clasping r. and also absorbent r. which ramify amongst the humus collected by the pi. itself. The aerial r. of some A. possess a velamen like Orchids. The 1. of Philodenaron cannifolium Schott have swollen petioles full of large intercellular spaces lined with mucilage. When rain falls these fill with water and act as reservoirs. [Cf. Schimper's Epiph. Veg. A merikas. ]

Fls. without br., usu. massed together on a cylindrical spadix enclosed in a large spathe ; the spadix usu. terminates a joint of the sympodium (the 'continuation' bud is generally in the axil of the 1. next but one before the spathe), so that there is only one formed each year. Fl. $ or monoec. (dioec. in Arisaema), with or without P. Sta. typically 6 but usually fewer (down to i), often united into a synandrium (e.g. Colocasia, Spathicarpa) ; in Ariopsis the synandria again united to one another. Stds. often present, and these also may be fused into a synandrodium as in Colocasia. G with much variety of structure ; frequently reduced to i cpl. Berry. Outer integument of seed often fleshy. Endosperm or none.

Infl. usu. of many fls. and cymose or racemose (raceme or umbel). In the former case it is dich., but as in Caryophyll. the one branch tends to outgrow the other, and a monoch.

Asclepias) the infl. is extra-axillary.

Fl. 5, reg , j-merous, usu. small. K 5, quincuncial, the odd sep. post.; C(5) usu. rotate or campanulate, with conv. or valvate aesti- vation. The essential organs (5 sta., 2 cpls. ) are complex. The sta. and style are usu. united to form a gynosteginm. The cpls. are free below as in Apocyn., but united at the tip with a common style ; ov. sup. The head of the- style is large and variously shaped, and the stigmatic surface is usually upon the edge or under side of it. To its margin are united the anthers of the 5 epipet. sta. ; the filaments of these are short or non-existent. The pollen in § i is united merely in tetrads, in the higher group, comprising the bulk of the order, into pollinia, as in Orchids. Usu. each anther contains two. In this group also there are curtain-like projections at the sides of the anthers, leaving a narrow slit between each pair of anthers.

The pollen is removed from the anthers by a curious mechanism — the translator. This differs in the two suborders and so also does the fert. method. The translator always stands between two anthers and serves to carry away half the pollen from each of them. In the Periplocoideae it is a spoon- or funnel-like body with a sticky disc at the narrow end. Into it is shed the pollen from the two half anthers next to it, and as the sticky disc projects outwards in the male stage of the flower an insect will be likely to get it attached to its head, and carry it about like the pollinia of an orchid. In visiting a second flower the pollen may be placed on the stigmalic surface. In the Cynanchou/eae, on the other hand, there are pollinia, and the trans- lator has a different structure. It forms an inverted \-shaped organ, the foot of the Y being formed by the adhesive body (corpiisculuni] ; from this diverge the threads (retinaculn) which are attached to the pollinia, one in each anther. An insect in obtaining honey catches its leg in the slit between the anthers, and in drawing it up removes the pair of pollinia. The threads as they dry contract on the inner side till the pollinia meet, thus closely clasping the insect's leg. In drawing the leg through a similar slit in another fl. the pollinia catch on the stigmatic under-surface of the stylar head. (Cf. Apocynmn, which shows an approach to this mech.)

The backs of the anthers as a rule bear appendages (ciiculli) forming a corona. In some cases it springs from the C. It may consist of small teeth, or be more complex, as in Asclepias and Ceropegia, and often takes up the functions of secreting and storing the honey.

carriage. Endosperm slight, cartilaginous. Some give useful fibres.

Closely related to Apocyn., the only absolute distinction being the presence of translators in Ascl. ; otherwise the two sub-orders of each form a corresponding series, and the lower one in each is almost as nearly related to the corresponding one in the other order as to the higher group in its own order.

Herbs with umbellate infls. which spring from the stem between the petioles of the opp. 1. (cf. Cuphea), or above or below this. Two explanations exist, but which is right the evidence available does not show. Either the inn. is axillary to the 1. below it and is 'adnate ' to the stem (cf. Cuphea), or it is the termination of a shoot, and the stem is really a sympodiuin.

The cuculli of the anthers form little pockets, into which honey is poured by the horn-like nectaries that project from them. Insects walking over the fl. and sipping honey frequently slip their legs down the sides of the gynostegium, and in drawing them up catch in the slit between two anthers and remove the pollinia (cf. family). The process may be watched on A. Cormtti Decne. in gardens.

L. (the bird's nest fern) is an interesting epiphyte of the Old World tropics. It bears a rosette of leaves forming a nest in which humus collects; the roots ramify in this and obtain food and water. A. rhi- zophylhun Kunze is the walking fern, so called because the leaf-tips when they touch the soil bud into new individuals, and thus the plant spreads to some distance.

It is cult, in Eur. to 69^° N. and forms the staple of the food of a large population. It occurs in two chief forms, the common oat with open spreading panicles, and the Tartarian oat with contracted one-sided panicles. [See De Candolle's Orig. of Cult. Pits. p. 373.] The 2-6-flowered spikelets form a loose panicle. The paleae are awned, the awn of the inf. palea being usually twisted and hygroscopic. In A. steriiis L. the awns cross, and when wetted try to uncurl and thus press on one another till a sort of explosion occurs jerking away the fruits.

Azolla Lam. Salviniaceae. 4 trop. and subtrop. General structure like Salvinia. Two 1. are formed at each node, from (he dorsal half of a segment of the apical cell ; from the ventral half are formed roots and branches, but not at every node. The 1. are all alike ; each is bilobed and has a small cavity near the base, opening by a small pore, and inhabited by the Alga Anabaeita. The r. hang freely down in the water ; usually the root cap is thrown off after a time and the r. comes almost exactly to resemble the submerged 1. of Salvinia. The sporocarps are formed in pairs (4 in A. mlotica] on the ventral lobes of the first 1. of the branches. Each contains one sorus. The microspores are joined together into several masses in each sporangium by the hardened frothy mucilage (epispore, cf. Sal- vinia). Each of these massulae has its outer surface provided with curious barbed hairs (glochidia), and escapes on its own account. The megasporangium contains one spore. It sinks to the bottom ; decay of the indusium frees the spore and it germinates, giving rise to a ? prothallus which floats about on the water and may be anchored to a floating massula by the barbs.

Bamboo, a member of the i3th group of Gramineae, char, by stems that become woody below and often grow to great size. The trop. forms usu. grow in clumps, which continually expand, the new shoots appearing at the outer side ; the subtrop. and temp, forms are usu. continuous in their growth. There is a big rhiz. below ground and erect perenn. woody stems above, which appear in the rains (or spring) and grow rapidly to the full height, when the scale 1. fall and the leafy branches spread out. Growth is very rapid in Dendrocalanuts giganteus Munro, reaching as much as 41 cm. a day (cf. Lock, Ann. Perad. II. 211). Some climb. The height is often great, reaching to 1 20 feet in some forms.

Some fl. annually, others at longer intervals, and some are like Agave and Corypha, flowering only once, all together, and then dying down. They fl. only when in full leaf, and as the infl. grows the 1. usu. fall. The seedlings grow for several years without forming tall shoots, producing large well-stored rhiz. They then send up shoots increasing in length from year to year.

Spikelets 2-co -flowered in racemes or panicles. Sta. usu. 6. The economic uses of bamboos are very numerous, esp. in Asia. The stems are hollow, with cross partitions at the nodes, and the wood is elastic and very hard, owing to the deposition of silica in the cell walls. The stems are consequently very light and strong, and are also easily split. They are largely used in building, entire as posts, and split as roofing tiles, while the houses in Assam, Burma, and Malaya are often made of bamboo split finely, and woven into a kind of mat which is fastened upon bamboo posts. Bridges are often made of them, and they furnish water-pipes, water-vessels, gutters, floats, beehives, walking-sticks, pipes, flutes, masts, furniture, household utensils, agricultural tools, &c. The distichous bamboo shoot, with the side branches cut down to about 6 inches, is used as a ladder. Split bamboos, with the edges trimmed sharp, are used as* grass cutters, and \vill keep lawns in good order. Finely split bam- boos are made into mats, blinds, rigging, baskets, fans, hats, coarse clothing, umbrellas, ropes, brushes, &c., esp. in Japan, where fine work is done in bamboo. Paper is made from bamboos in China and elsewhere. The stout stems of the male bamboo (Dendrocalamus strictus Nees) are used for the handles of lances. The stems cut into lengths form very useful flower pots, largely employed in tropical gardens. The young shoots are eaten like asparagus, and the poorer natives also use the seeds as food. In the stems of B. arundinacea \Villd. curious concretions of silica are found, known as tabashir or bamboo manna, used in the East as a medicine in many diseases.

In the axils groups of little tubers are frequently found ; these are not axillary branches, but are borne upon the true axillary branch, which does not lengthen. They also repr. easily by adv. buds which readily form on pieces of 1. cut off and placed on the soil under suitable conditions of moisture &c. (the common mode used in horticulture).

Berberis (Tourn.) L. Berberidaceae. 160 sp. S. Am. B. vulgaris L. (barberry) Brit. Shrubs. Two sections. In § i, Mahonia (Nutt.), the 1. are pinnate; many cult, shrubs. In § 2, Euberberis, the 1. are simple, but usu. show a joint where the blade meets the petiole, seeming to indicate a derivation from a cpd. 1. There are also 'short' and ' long ' shoots (if. Coniferae) in this §, to which B. vulgaris belongs. The latter have their 1. met. into spines (usu. tripartite) ; transitions may often be seen. The former stand in the axils of the spines and bear green 1. and racemes of fls. (afterwards sometimes elongating to ' long ' shoots). The pollination mechanism is in- teresting. The upper surface of the base of each sta. is sensitive to contact, and when it is touched by an insect in search of honey (secreted by the nectaries upon the bases of the inner P 1.) the sta. springs violently upwards, covering the side of the visitor's head with pollen, which it may place on the stigma in the next flr. visited. The fr. is sometimes made into preserves.

An interesting.point about the common barberry is its connection with the disease known as black rust, which occurs on wheat and other Gramineae. The fungus (Pitccinia graminis or Aecidium berberidis} passes through two alt. stages in its life history, one on the grass, the other on the barberry, so that if there are no barberry plants in a district, it is to a large extent, though by no means absolutely, insured against black rust.

and the mangold-wurzel. The plant is a biennial and stores reserves in the root, the non-nitrogenous materials taking the form of sugar.

The sugar-beet is largely cult, in W. Eur. for its sugar, a for- midable rival to the older industry of cane sugar. The sugar-contents of the roots have been continually improved by selection, and now frequently represent over 2O°/0 of the weight. Germany grows ii million tons of beet sugar annually, and other countries about another 3 millions. [Herzog, Monographic der Zucker-riibe, Ham- burg, 1899.]

The garden beet is a favourite vegetable ; the mangold is valuable for feeding cattle, &c. The 1. are sometimes eaten like spinach.

Boraginaceae (EP., BH.). Dicots. (Sympet. Tubiflorae; Polemo- niales BH.}. 85 gen. 1600 sp., trop. and temp., esp. Medit. Most are herbs, perenn. by fleshy roots, rhiz., &c. ; a few shrubs and trees. L. usu. alt., exstip., generally, as well as the rest of the plant, covered with stout hairs (hence the name Asperifolieae, by which the B. are sometimes known). Infl. a coiled cincinnus, sometimes double, with a marked dorsiventrality. As the fls. open it uncoils, so that the newly opened fls. face always in the same direction. The morphology of this infl. is but imperfectly understood; adnation or concrescence occurs, and apparently dichotomy at the growing apex. The general agreement is, however, in favour of the view that the "boragoid," as it is sometimes called, is composed of dorsi-ventral monopodia. Cf. Nat. Pfl., Miiller in Flora, 94, Schumann, Morphol. Studien, n.

Fl. ?, usu. reg., hypog., and 5-merous. rarely valvate, the odd sepal post.; C (5), funnel-shaped or tubular, the limb usu. flat; AS, epipet., alt. to petals, anthers introrse; G(2), on hypog. disc, usu. 4-loc. by "false" septum (see Labiatae), usu. with gynobasic style ; ovules i in each loc., erect, anatr. Fr. a drupe or 4 achenes. Seed with straight or curved embryo in usually slight endosp. ; the radicle directed upwards. [Cf. § V.]

The floral arrangements are interesting. Most B. have a short tube, partly conceal- ing the honey; many (esp. IV. i and 3) have scales projecting inwards from the throat of the corolla, fully concealing the honey, protecting it from robbery and narrowing

the entrance, so that visiting insects must take a definite track. " Many sp., in the course of their individual development, seem to

recapitulate to us the evolution of their colours — white, rosy, blue in several sp. of Myosotis; yellow, bluish, violet in M. versicolor; and red, violet, blue in Pulmonaria, Echium, &c. Here, white and yellow seem to have been the primitive colours." (Miiller.) Many B. are heterostyled, e.g. Pulmonaria. The fls. of many sp. are pendulous (and thus bee-flowers), e.g. Borago, Symphytum. Echium is gyno- dioecious.

Classification and chief genera (after Giirke) : I. CORDIOIDEAE (drupe; style terminal: twice bi- lobed): Cordia.

II. EHRETIOIDEAE (do.; style simple or bi-lobed or

double ; no ring of hairs) : Ehretia.

III. HELIOTROPIOIDEAE (do., do., but ring of hairs near

tip of style): Tournefortia, Heliotropium.

IV. BORAGINOIDEAE (style gynobasic : achenes).

1. Cynoglosseae (fl. reg. ; base of style more or less conical ;

tips of achenes not projecting above pt. of attachment) : Omphalodes, Cynoglossum, Rindera.

2. Eritrichieae (do., but tips projecting above pt. of attach-

ment): Echinospermum, Eritrichium, Cryptanthe.

3. Anchuseae (fl. reg.; base of style flat or slightly convex ;

achenes with concave attachment surface) : Symphytum, Borago, Anchusa, Alkanna, Pulmonaria.

4. Lithospermeae (do., but surface of attachment flat) : Myo-

sotis, Lithospermum, Arnebia, Cerinthe.

5. Echieae (fl. zygomorphic) : Echium.

The blue pendulous fl. secretes honey below the ovary ; the elastic sta. form a cone and dehisce introrsely from apex to base, the pollen ripening gradually and trickling into the tip of the cone. Insects probing for honey dislocate the sta., receiving a shower of pollen (cf. Erica, Galanthus, Cyclamen). In older fls. the stigma, now ripe, projects beyond the sta. so as to be touched first.

The wood of the trunk is very hard and durable, and resists salt water ; it is also used for rafters, well-sweeps, &c. The large fanshaped 1. are used as thatch, and made into olas or writing "paper" sheets, the writing being done upon them with a stylus. From the base of the 1. Palmyra fibre is collected, and used for making brushes, &c. The split 1. are woven into mats, baskets, &c. The fr. is eaten roasted, and the infl. is tapped for toddy (cf. Cocos, Agave) from which sugar or jaggery is

In many ferns the branches are on the 1. bases, but in Equisetum and fl. plants are usu. axillary. Usu. only one in each axil ; if more than one, the others are accessory ; if side by side, collateral, Allium, Araceae, Crataegus, Liliaceae, Ahiscari, Quercus, Salix ; if one above the other, serial, Aristolochia, Calycanthus, Cercis, Colletia, Fuchsia, Gleditschia, Robinia, Syringa. Branches of two kinds — long and short shoots, or shoots of unlimited and limited growth — occur in Pinus and other Coniferae, Berberis, Cactaceae, Ginkgo, Spergula.

Branching may be of two types — monopodial, Punts and other Coniferae, Orchidaceae, Paris, Pathos, or sympodial, Acorus, Aglao- nema, Ancistrocladus, Anonaceae, Anthurium, Araceae, Asariim, Eichhornia, Fagus, Iridaceae, Iris, Juncus, Liliaceae, Nartheciuin, Orchidaceae, Peperomia, Pistia, Polygonatttin, Pontederiaceae, Pota- mogeton, Ranunculus, Rhaphidophora, Ulmaceae, Vilis, Zostera.

B. nigra Koch is the black mustard, whose seeds yield the condiment. B. oleracea L. is the cabbage, with the various races derived from it, such as cauliflower and broccoli (fleshy infl.), kale or curly greens or borecole, brussels-sprouts (a form in which miniature cabbages are produced in all the leaf-axils on the main stem), kohl-rabi or knol- kohl (trop.) (a thickened stem, or conn, showing leaf scars on its surface), &c. B. campestris L. is the turnip, a biennial with thickened root, and a var. of it — B. Napus L. — is the rape, used in salads and in the preparation of rape- or colza-oil, expressed from the seeds. [See De Candolle's Orig. of Cultiv. Pits.] It is of interest to notice the great variety of morphology in the veg. organs, correlated with the different ways in which storage of reserve materials is effected, in the root, stem, leaf, flowerstalk, &c.

Sauer-kraut, or salted cabbage, made by packing cabbage shreds in barrels with salt and pepper, and slightly fermenting, is a favourite food in Germany, esp. for winter use.

The outer coat of the seed has mucilaginous cell-walls which swell when wetted (cf. Linum).

(xero., living on rocks &c.), but the bulk of the sp., by virtue of their good seed- distribution and their xero. habit, have become epiph., forming a very char, feature in the veg. of trop. Am., more so than the orchids, which they surpass in number of individuals though not of sp. Most have a very reduced stem, bearing a rosette of fleshy 1. channelled on the upper surface and fitting closely together by their bases, so that the whole pi. forms a kind of funnel, usu. full of water. In this are dead 1., decaying animal matter and other debris (certain sp. of Utri- cularia live only in these pitchers). There are a number of adv. r.

which fasten the plant to its support, but which do not aid in its nutrition, or very little. The bases of the 1. are covered with scaly hairs by which the water in the pitcher is absorbed. Water is stored in the 1., which consist largely of water-tissue. They have a thick cuticle and often bear scaly hairs that reduce transpiration. Some show a totally different habit to this, e.g. Tillandsia usneoides (q.v.). [See Schimper, Epiph. Veg. Amerikas.}

(Opuntia missouriensis as far as 59° N.), and far up the mountains (to 12,000 ft. and even higher). Even in the damp forest regions some sp. appear as epiphytes.

fleshy, of various shapes, rarely bearing green 1. , and usu. provided with sharp barbed thorns, which give protection against animals. We may consider briefly some of the more important types of shoot found in C. (refer to genera for further details). The nearest approach to the ordinary plant-type is perhaps Pereskia, which has large green 1., somewhat fleshy, in whose axils are groups of thorns mixed with hairs ; the space occupied by these is termed the areole. About the morphology of the spines there has been much dispute; most authors regard them as repres. the 1. of the axillary shoot, whose stem is undeveloped, but there is also good evidence in favour of the view that they are "emergences." In some gen. they are provided with barbs. The next stage is found in Opuntia, where the stem has taken over the water-storing and assim. functions, but still bears 1. ; in some sp. these aid the stem functions throughout life, but in most they fall off very early, and the stem is usually flattened to expose more surface to air and light. Then we come to Leuchtenbergia, which has an aloe-like habit with the areoles on the tips of the apparent 1. ; the fl. arises either in the axil of the "leaf" or on the areole. Development shows that the apparent 1. is really a cpd. structure. The bud stands, not exactly in the axil, but on the base of the 1., and the two grow out together to form a leaf-cushion or mammilla^ at the outer end of which is the growing point and the rest of the 1. itself; the latter is represented by a small scale (often microscopic) and the former gives rise to the thorns, &c. on the areole. The same phenomenon is seen in Mammillaria, Cereus sp., &c. In some cases the growing point divides, during the growth of the mammilla, into two, one on the tip, the other in the axil, of the cushion. The latter gives rise to the fl. In Cereus, Echinocactus, &c. the stem is ± cylindrical, bearing ribs on which are the areoles at regular intervals; the rib is formed by the "fusion" of mammillae, i.e. by the growth of the tissue under them during their development (cf. formation of sympetalous corolla). In Phyllocactus, Epiphyllum, and sp. of Rhipsalis some or all of the shoots exhibit a flattened leafy form with areoles in notches on their edges. This form appears to be derived from the preceding by abortion of some of the ridges, and reversions are often seen (they appear if access ot light lie prevented). Lastly, other sp. of Rhipsalis show perfecily cylindrical stems.

The bulk of the internal tissue consists of parenchyma in which water is stored ; the cell-sap is commonly mucilaginous, thus further obstructing evaporation. The cuticle is thick, and the ridges of the stem are usu. occupied by mechanical tissue, whilst the stomata are in the furrows. Everything thus goes to check transpiration to the utmost extent ; it is very difficult to dry a cactus for the herbarium, and its vitality is very great. Its growth is slow, but sp. of Cereus, &c. reach a great size. Veg. repr. is frequent in the mammillate forms, and occurs to some extent in others. In garden practice, cacti are often multiplied by cuttings, for a piece cut off and stuck into the soil will usually grow. Grafting is also largely resorted to.

Fls. usu. solitary (exc. Pereskia), borne upon or near the areoles or in the axils of mammillae, large, brightly coloured, §? , reg. or •!•. P (oo ), showing gradual transition from sepaloid to petaloid 1., spirally

Campanula (Tourn.) L. Campanulaceae (i. i). 300 N. temp, and trop. Mts., esp. Meclit. ; 8 Brit. incl. C. rottmdifolia L. (harebell, blue-bell of Scotland). The pollen is shed in the bud, the sta. standing closely round the style and depositing their pollen upon the hairs. As the fl. opens the sta. wither, exc. the triangular bases that protect the honey, and the style presents the pollen to insects. After a time the stigmas separate and the fl. is 9 ; finally the stigmas curl right back on themselves and effect self-pollin. (See fam. and cf. Phyteuma, Jasione.) Seeds light and contained in a caps., which if erect dehisces at the apex, if pend. at the base, so that the seeds (cf. Aconitum) can only escape when the plant is shaken, e.g. in strong winds. Several are cult. (Canterbury bells, &c.).

Campanulaceae (EP., BH.}. Dicots. (Symp. Campanulatae). 60 gen. 1000 sp., temp, and sub-trop., mostly perennial herbs (a few trees and shrubs), with alt., exstip. 1., and usu. with latex. The infl. may term, the primary axis, or one of the second order. It is generally racemose, ending with a term. fl. in Campanuloideae. In some cases, instead of single fls. in the axils of the bracts of the raceme, small dich. occur [cf. Labiatae). Others have the whole infl. cymose (Canarina, Pentaphragma, &c.).

Fl. usu. 5 , reg. or -|- , epig., generally 5-merous, the odd sepal post, in Campanuloideae, but anterior in the other groups. In these, how- ever, a twisting of the axis through 180° takes place before the fl. opens [cf. Orchid*), so that the odd sepal is finally post. K 5, open ;

C (5) valvate ; A 5 epig. ; anthers intr., sometimes united ; G (5), (3) or (i), multi-loc. with axile plac. bearing oo anatr. ov. Style simple ; stigmas as many as cpls. Caps, dehisc. in various ways in different gen. , or berry. Fleshy endosp.

The nat. history of the fl. is of interest, both in itself and as exhibit- ing transitions to the Composite type. Honey is secreted by a disc at base of style and covered in most cases by the triangular bases of the sta., which fit closely together and only allow of the insertion of a proboscis between them. This, taken together with the size of the fls., their frequently blue colour and pendulous position, points to their being best adapted to the visit of bees, as is the case, but there are also many other visitors of various insect classes, so that this fam. cannot be placed in the fl. class H but must go into B. A few exceptions occur; the bulk of the fam. has large fls., conspicuous by themselves, but Phyteuma and Jasione have small fls. massed in heads, and come into class B' along with the Compositae.

The general principle of the fl. mech. is the same throughout, and agrees with that of Compositae. The fl. is very protandr., and the

style (with the stigmas closed up against one another) has the pollen

shed upon it by the anthers, either in

the bud or later. Usu. there is a bunch

of hairs upon the style to hold the

pollen. For some time the style acts

as pollen-presenter to insects ; after a

time the stigmas separate and the ?

stage sets in, and finally, in many cases,

the stigmas curl back so far that they

touch the pollen still clinging to their

own style, and thus effect self-pollin.

Classification and chief genera (after Schonland) :

I. CAMPANULOIDEAE (fl. actinomorphic, rarely slightly zygomorphic; anthers usu. free):

1. Campattuleae (cor. valvate; fl. symmetrical): Campanula, Phyteuma, Wahlenbergia, Platycodon, Jasione.

2. Pentaphragmeae (cor. valvate; fls. as) mmetric, in cincinni) : Pentaphragma (only genus).

3. Sph-nocleae (cor. imbricate) : Sphenoclea (only genus).

II. CYPHJOJDEAE (fl. zygomorphic; sta. sometimes united; anthers free) : Cyphia, Nemacladus.

III. LOBELIOIDEAE (fl zygomorphic, rarely almost act'no- morphic; anthers united) : Centropogon, Siphocampylus, Lobelia.
