BY W. EDGAR EVANS, B.Sc., CARNEGIE FELLOW IN BOTANY. With Plates LIII-LIV. INTRODUCTION. THE germination of seeds, though by no means a neglected subject, is one which still requires much investigation. The chemistry and biology involved in the solution and absorption of perisperm and endosperm; the further development of the embryo both during and after germination, especially from the standpoint of phylogeny ; and the effects produced on this by differences in the environment of the seed at the time of _ germination—for example, deep as compared with shallow sowing, the results of chemical or physical stimulation, and the like,— these are a few of the lines of research which seem most likely ~ to repay fuller study. Moreover, it must not be thought that such problems need no more consideration because good work relating to them has been already published, for it will be found on examination that the gaps in our accurate knowledge often exceed the knowledge itself, making it even yet impossible to definitely or satisfactorily answer many an important question arising from the study of germination, Our information regarding the relation which leaf and stem bear to one another is an excellent example of this state of affairs, for there are at the present time two schools of botanists holding diametrically opposite views on the matter. Those of the first consider the leaf an essentially lateral structure ; . it has been evolved as a lateral outgrowth from the stem which bears it, while leaf-like organs which seem terminal in origin must be regarded in either of two ways—they are only apparently terminal, or they are not homologous with leaves. Botanists who uphold the second school maintain, on the other hand, that the leaf was originally terminal ; each successive leaf arose from {Notes R.B.G., Edin., No. XXI, August 1909. ] 2 the base of that which preceded it, while the axis was in course of time derived from their superposed basal portions. In this way, it is argued, the leaf became pushed to one side and assumed the lateral position which it occupies to-day ; its development gradually became arrested, and by lagging behind the succeeding internode it now appears lateral in origin. In the seedlings .of certain monocotyledons—for instance, Juncus, Sparganium, and Pistia—it has been shown that the first few leaves arise one from the base of the other, and that to begin with there is no axis visible. Very soon, however, it can be seen making its appearance, at first hardly discernible, but more and more prominent as each successive leaf is produced, till finally the leaves arise upon it in quite the normal way. Just as the zoologist has found impressed on the developing mam- malian embryo the shadow of its phylogeny, so do these botanists who believe in a terminal leaf see a proof of their theory in the ontogeny of such a seedling. Against this it is argued that a fuller investigation will probably show that the conditions existing in those unusual cases can be best explained as arising from a more or less complete arrest or even suppression of the axis; and since the species in which the peculiarity has been noted are chiefly hydrophytes and geophytes, it is suggested that the cecological conditions which have given rise to such types of vegetation may also tend to produce this sort of seedling structure. At the suggestion of Professor Bayley Balfour, I began, in _ the autumn of 1905, a careful investigation of the structure of monocotylous seedlings at various stages during and after germination ; and also of embryos taken from ripe seed. Since then the greater part of my time has been occupied by the work, and I have collected a large amount of material, much of which has now been carefully examined. The effect of deep and shallow seed-sowing upon the various organs of the young seedling, and the development of the plumular meristem, have in particular been kept in view, not only when germinating the seed, but also in the cutting and examination of sections. The object of this paper. is to put on record some of the results obtained, chiefly ‘as regards the latter question. After some thought I have decided that the best way in which ‘to avoid confusion is to select a small number of the plants examined, to describe these fully, and to give in each case a list of those species which, in the matter of their plumule, resemble the type chosen. An attempt has been made to so arrange the examples that they may form a series, beginning with one in which the leaves always appear lateral, and ending with as extreme a case of stem suppression—if indeed it be such—as 3 possible. The account of each will be complete in itself, and reference will there be made to any papers relating to the plant under discussion. A final chapter will be added in which the whole question will be reviewed and conclusions drawn ; this will include a more general bibliography. I believe that in this way a clearer view of the whole subject will be secured than in any other, for, while there are very few plants whose germina- tion is perfectly identical, there are several well-marked types of germination amongst monocotyledons, which might be lost sight of if too many examples were taken in detail. A few remarks on the methods I have employed in germinat- ing seed; preserving, cutting, and mounting specimens for the microscope; and in producing the photo-micrographs which illustrate the paper, may be of use to other workers. Germination of the seed.—Seed was successfully germinated on the surface of absorbent material such as blotting-paper and cocoanut fibre. Better results were obtained, especially with certain species, by placing the seed in pots of light sandy soil, the depth of sowing being equal to the thickness of the seed. A germinating case was experimented with, but was not so suc- cessful as a properly constructed propagating house. In many instances it was found necessary to specially arrange the posi- tion of the seed, so that the young plant might develop as far as possible in one plane, otherwise good sections could not be obtained. Fixing the specimens.—A mixture of two parts of absolute alcohol and one of glacial acetic acid proved thoroughly satis- factory, and enabled fixation to be rapidly and easily performed. The specimens were allowed to remain about twenty minutes in this reagent, were washed in go per cent. methyl alcohol to remove the acid, and in most cases preserved in spirit of this strength till required for embedding. Embedding:—All specimens were embedded in paraffin in the usual way, xylol being the solvent employed. The most generally useful wax was found to be that having a melting-point of 52° C., though occasionally one melting at a higher temperature was advantageous. Cutting the sections—In order to obtain serial sections as easily and quickly as possible a Cambridge rocking microtome was used. The most satisfactory thickness of section was found to be rop, and all sections figured are this thickness unless it be otherwise stated. The ribbon of sections in paraffin was allowed to spread upon warm water, while it was found necessary to ensure attachment to the slide by means of Meyer’s albumen solution. Staining the sections. —After having compared the results 4 obtained by the use of a number of stains, I am satisfied that hematoxylin counter-stained with Bismarck-brown is the best -all-round combination. It is unsurpassed if the sections have to be photographed ; while it is more restful to the eye when a large series of sections have to be examined than are most colours. I have also used hematoxylin along with saffranin and obtained good photographs. Photographing the sections.—In my opinion the flame of an oil lamp is preferable as a source of illumination to more powerful methods of lighting such as acetylen and incandescent gas. For the best results the condenser should be achromatised and fitted with an iris diaphragm. Strangely enough, contrary to the published experience of most workers, I have obtained better photographs without the use of an eyepiece than with one, even when using a_ specially constructed projection- eyepiece and making all adjustments most carefully. Backed orthochromatic plates give in most cases the best results, and when the sections have been stained with Bismarck-brown no light-filter is necessary. In every case the magnification in diameters was carefully ascertained at the time of taking the photograph Many workers find it difficult to obtain sufficient density in their negatives without having recourse to intensification. The best all-round developer I am aware of is one in which the re- ducing agent is a mixture of metol and hydroquinone in the proportion 1:2; the accelerator being sodium hydrate solution to which a little citric acid is added to prevent stain. In conclusion I desire to state that I have carried out this investigation, first, as a Carnegie research scholar, lateras a Carnegie research fellow, at the Royal Botanic Garden, Edinburgh. My grateful thanks are therefore due to the Carnegie Trust for the Universities of Scotland ; as well as to Professor Bayley Balfour, under whose supervision I have worked, for kind assistance in many ways, and for supplying me with seed of many plants, some of considerable rarity. I, THE GENUS ASPARAGUS. With the exception of Asparagus medcoloides, Thunb.—merely mentioned by Klebs (4) in a list of those monocotyledons having a type of germination which he terms “‘ type 1 ’—the only member of this genus whose embryo and seedling have been even super- ficially described appears to be A. officinalis, Linn. This is the 5 more surprising since, as far back as 1809, Mirbel (1) published a wonderfully accurate account of the external features of the seedling in the latter plant ; while the extreme leaf reduction and other characteristics of the numerous species might have been expected to stimulate further investigation. I have examined six Asparagi other than A. officinalis,namely, A. comorensis ; * A. medeoloides, Thunb. ; A. plumosus, Baker ; A. trichophylius, Bunge ; A. tenuifolius, Lam. ; and a species, the seed of which was supplied to me as that of A. rugulosus, a name I have been quite unable to trace. The germination in all of these is remarkably similar, differing only in the number of kataphylls—each with a single axillary rhizome bud—which remain within the sheath of the cotyledon. The plants examined can in this respect be separated into two groups, those of the first having at the base of their primary axis one, those of the second two of these large underground buds which, when they grow, produce a part of the sympodial rhizome before forming epigeous stems. Since the retention of one kataphyll within the cotyledon sheath is characteristic of all species, and since the retention of two instead of one must be regarded only as a further specialisation along the same lines, it is no distortion of the facts to state that the various species of the genus show as close a correspondence in the features of their germination as they do in the anatomy of their mature organs. In studying any plant-embryo and following out the changes which take place in it as it escapes from the seed and establishes its independence, it is essential that the main structural peculi- arities of adult specimens be borne in mind, if the facts under observation are to be easily or thoroughly appreciated. For this reason the chief characteristics of the full-grown vegetative parts in the genus Asparagus may be briefly stated here, before passing on to describe in detail the type of embryo and germina- tion which I wish also to associate with it. Of these there are two, both very strongly marked and equally worthy of mention : first, the perennation by means of a sympodial rhizome and fleshy storage-roots lying at some depth in the soil ; second, the reduc- tion of the leaves to mere scales—or in part to thorns in the case of certain scrambling species such as A. Sprengeri, Regel—and their replacement by cladodes (Plate LIV, Fig. 16), sometimes remarkably leaf-like as in A. medeoloides (C, Fig. 3). The usual presence of long, stout, almost unbranched pull-roots, though less important, should not be lost sight of. to horticulturists 7 a ree of years, ee does not seem to have been eciicale described, and e been unable how or w it received the name A. comorensis. ae "ieconibse to the Index Kewensis, it may synonymous with 4. crispus, Lam., it is certainly not, as has been thought, a form of be 6 Be Soke.

These are fairly large, quite close together, and when ripe are often more or less flattened on two sides owing to the pressure they exert upon each other during their development ; when they escape crushing, however, they are almost spherical. On the thin, dark-coloured seed-coat there can, as a rule, be distinguished the hilum—a flat roughish area; and the micropyle, which has the appearance of a small dome-shaped protuberance. If the seed be carefully sliced open in a plane traversing both hilum and micropyle, a section will be obtained passing longitudinally through or by the side of the embryo, easily seen lying in the semi-transparent endosperm which is of extreme hardness, probably that it may resist the digestive processes of birds which feed upon the berries. ; ae * X6.:. + . a > Ot M ae: H Pte. &. eS i oe Asparagus seeds, passing acs across pe embryo. Asparagus comorensts ; B, A. medeoloides Thunb. ac Hi, hilum ; Pl., plumule ; Cot., cotyledon The embryo may be straight as in A. medeolotdes (B, Fig. 1) and A. officinalis ; or somewhat curved as in A. rugulosus and A. comorensis (A, Fig. 1). It is long and narrow, reaching from the micropyle, against the dome-shaped covering of which its radicle is pressed, almost to the opposite side of the seed. In longitudinal section the extremity of the radicle shows all the structure of a normal root-apex, very well developed as compared with many other embryos (Plate LIII, Fig. 4). Ata distance above this, varying in different species from th (in A. rugulosus) to ird (in A. medeoloides) of the total length of the embryo, is hated the plumular meristem, a laterally placed, rather slanting patch of tissue showing no differentiation into axis and leaf (Plate LIII, Figs. 8,9). The remainder of the embryo forms the cotyledon (Plate LII, Figs. rand 5), whose lowersheathing portion completely enfolds the plumule ; the minute slit through which the shoot will emerge on germination being discernible, though not without 7 difficulty, at its base (Plate LIII, Figs.2and 7). So far as my in- vestigations have gone, the vascular system of the embryo (Fig. 2) seems very variable in certain respects, not only in different, but also to a less degree in the same, species. Scholz (5B), referring to A. officinalis, mentions that three vascular-bundles traverse the cotyledon ; while Miss Sargant (7) has observed in A. officinalis and A. decumbens an increase in the number of xylem strands in the hypocotyl. This is due, she states, to plumular traces which in these cases are similar to, and behave in the same way as, the cotyledonary ones during the transition to the root. In the cotyledons of those Asparagi which I have examined three Fic. 2.—Asparagus rugulosus. A, Radial longitudinal section of the embryo, t .

Cot., cotyledon ; Hyp., bundles occurred only in two—A. plumosus and A. trichophyllus (Plate LIII, Fig. 1)—though not constantly in the latter plant, four being also met with. In A. rugulosus (Fig. 2) the number was usually four, occasionally five as illustrated ; while in A. medeoloides, only a few specimens of which were cut transversely however, five bundles were observed. Counting the protoxylem patches in the central stele of the primary root, which, owing to the extreme shortness of the hypocotyl, forms nearly the whole of that portion of the embryo lying below the plumule, and com- paring their number with that of the bundles in the cotyledon, it was found that in some cases this was the same, while in others 8 there was an increase (Plate LIII, Figs. rand 3). The numbers noted are arranged below in tabular form, but it would be rash to attempt to drawconclusions from so’small a number of sections, and they are given chiefly to indicate that there is a lack of uni- formity in this respect. It may be pointed out, however, that | SPECIES, | Basithes in the cotyledon. hinicnuone oe the Root.

A. plumosus and A. medeoloides, both of which on germination retain two rhizome buds within the cotyledon sheath, also have most protoxylems in their root-stele. This appears, moreover, to be independent of the number of bundles in the cotyledon, since A. medeoloides has five, but A. plumosus only three. Germination. Seed of all the species examined was sown in a moist hot-house, one portion on the surface of cocoanut fibre, another in pots of sandy soil at a depth of an inch or more. About three weeks elapsed in most cases before the commencement of germination, though under similar conditions Scholz (58) states that seed of A. officinalis began growth in eight days. The discrepancy may be accounted for by the fact that this plant is hardy, while those I experimented with require in this country protection under glass. When germination commences, that part of the cotyledon situated just above the plumule begins to elongate. The radicle is thus caused to press against the dome-shaped covering of the micropyle, and since this is less thickened than the rest of the seed-coat it gives way and falls out like a little circular lid. As soon as the developing portion of the cotyledon has lengthened sufficiently to ensure that the slit at its base, through which the shoot has later to escape, is quite free, its growth ceases, with the result that the seed remains closely attached to the seedling (C, Fig. 3). By this time the radicle has begun to elongate very rapidly ; it develops into a very short hypocotyl and a stout, long-lived tap-root (Plate LIII, Fig. 15). Root hairs are not produced close to its apex, so that there is always a portion at the extremity of the root, behind the root-cap, free from hairs. 9 This is so from the very first, and we have here a marked differ- ence between seedlings of the genus Asparagus and those of many monocotylous families, such as the Juncacee and the Cyperacee. The hairs themselves are short and wonderfully persistent, densely covering the whole of the root with the exception of this apical part. The slit in the cotyledon occupies a slanting position facing upwards owing to the curving down of the short hypocotyl and the primary root towards the soil. The margins of the slit soon grow slightly, forming a somewhat leaf- like rim to the cavity which is enclosed (A, Fig. 3), and shortly afterwards the apex of the primary axis, capped by two sheathing leaves, makes its appearance from within. A little later there Fic. 3.—Asparagus medeoloides, Thunb. A, very young seedling. B, older stage. C, seedling one month old. H., hilum; S., seed; Cot.-sh., sheathing base of cotyledon; f.

(1, 2, &c.), axis (primary, secondary, &c.). also emerges a second structure, at the side of the developing stem away from the cotyledon and seed. This is the first leaf of the shoot, which invariably remains below ground at its base, partially enclosed by the cotyledon (B, Fig. 3). That this may be so the epicotyl is never elongated, even when the seeds are germinated at a depth of an inch or more below ground ; in such a case one or two internodes of the basal portion of the axis become longer than usual in order to reach the surface. In two of the species examined, namely, A. medeolotdes and A. plumosus, the second leaf of the shoot is also habitually retained by the side of the first, through the suppression of both the epicotyl and the internode immediately above it. These hypogeous leaves 2 Bie) are always sheathing kataphylls ; though when two are present the second is much smaller than the first and does not protrude beyond the sheath of the cotyledon (Plate LIII, Fig. 14). -In the axil of each kataphyll there is early formed a large bud which grows into the secondary stem, and this in turn produces below ground two contracted internodes bearing two sheathing kata- phylls, one or both of which subtend a single axillary bud, the process being repeated indefinitely. Even in those species retaining only one kataphyll below ground at the base of their primary axis—that derived from the plumular meristem directly —there are two in the case of the secondary one and all that follow, though as a rule only the second of these has in its axil a bud. In this way the sympodial rhizome so characteristic of the genus is built up from the bases of the aerial shoots. Let us now examine the changes which have taken place in the other parts of a somewhat advanced seedling. The suctorial end of the cotyledon (Plate LIII, Figs. 1 and 5) gradually enlarges within the seed as the reserve food-material of the endosperm becomes dissolved and absorbed. This is a slow process however, and the seed remains attached to the plant for a considerable period. The primary root in seedlings three or four weeks old has become more or less thickened—especially so in A. medeoloides (C, Fig. 3), many of the roots of which function solely as storage organs—and seems to act largely asa pull-root. It never branches, becomes wrinkled, and in fact presents all the peculiarities typical of such roots. Soon there arises, usually from the point where the hypocotyl and stem meet, a lateral root which branches and remains unthickened (C, Fig. 3). This is followed by other lateral roots proceeding from the rhizome as it is formed—for it must be remembered that two or more joints of this are produced each year—some of which develop in the same way as the primary root. The hypocotyl (Plate LIII, Fig. 15) remains short during the whole of its life, and, as I have already said, I have never, under any circumstances, seen one which had elongated. Thestem apex in older seedlings is always protected by two or more scale- leaves, which later on are left behind, but not until others have been produced to take their place. At first they appear opposite in pairs; then, as the internodes lengthen, they assume their true position, alternating ina } spiral. The first few scale-leaves of the stem—not including the basal kataphylls—sometimes have apparently no axillary buds, for example A. comorensis (Plate LIV, Fig. 16) ; but in other cases, such as A. medeolordes, may subtend lateral aerial branches or even cladodes (C, Fig. 3). In a longitudinal section of the stem apex in the latter plant (Plate LIII, Fig. 6) it is interesting to note how the development of the large leaf-like cladodes is almost as rapid as that of the EE leaves in whose axils they arise ; while the vascular traces run out not into the leaves but into the cladodes. There yet remains to be mentioned a matter of some interest and no little importance. Owing to the increasing girth of the seedling the sheathing base of the cotyledon becomes pushed to one side of the lower extremity of the stem; while opposite it, and at the same level, arise the one or two kataphylls, now no longer enfolded by it (C, Fig. 3). A. officinalis, the only species previously described, has only one of these, and Henslow (8) and others have thought that it represented a second cotyledon, delayed in development and reduced in size. Following out this idea still further, it has been suggested that monocotyledons have been derived from a dictotylous ancestor by the sup- pression of one of the cotyledons. A more detailed account of the changes which take place in the plumular meristem during .germination will be necessary before discussing this question. I may say, however, that while it seems quite likely that the ancestor of all present-day angiosperms was a dicotylous type, the above attempt to prove this will not stand examina- tion. The Development of the Plumular Meristem. After the examination of a large number of monocotylous embryos I have found that, knowing the relative development of stem and leaf in the mature plant, one can guess with fair accuracy what the structure of the embryonic plumule will be. In other words, I believe that the characteristics of the adult produced in response to its environment, have tended to appear ever earlier in the life-history of the individual, till now they are found impressed even on the embryo, shut up though it be within the seed. Moreover, I am inclined for this reason to doubt the utility of searching for evidence regarding a plant’s phylogeny in this region at least of its embryo. Applying what has been said to the genus Asparagus, let us consider what might be expected in the plumular meristem, and then observe how this agrees with its actual structure, as described later on. We are dealing with plants whose leaves are reduced to mere scales, while very much specialised branches function in their stead ; the stem has in fact become dominant over the leaf. It would therefore be natural to infer that the formation of leaf-primordia might possibly not yet have taken place in the embryo, and that in its subsequent growth the greater part of the plumule would be devoted to the formation of axis. Though in the case of many monocotyledons the plumule _ of an embryo taken from a ripe seed will be found to consist of one or more leaf rudiments arising from an axial part, in the I2 genus Asparagus it is quite undifferentiated. It would be incorrect to apply the term ‘“‘ bud”’ to the simple dome-shaped meristematic patch which here constitutes this region. It is laterally placed near the lower end of the embryo, and slants downwards and outwards so that it may almost be said to face the slit in the base of the cotyledon through which the structures derived fromit are later on to find an exit (Plate LITT, Figs. 8and 9). On the commencement of germination there is developed from a portion of its outer and lower margin, constituting less than a quarter of the entire meristem, a small swelling, which grows slowly larger and finally forms the first leaf of the primary axis (Plate LIII, Figs.q-11). As previously mentioned, this is a kata- phyll, and remains permanently in the position in which it comes into existence, directly opposite the cotyledon ; while very soon a FG. 4.—Transverse sections through the base of the primary axis in Asfarag7, havin respectively one and two basal kataphylls.

This bud takes part in the construction of the main under- ground sympodial rhizome. In those species which have two kataphylls at the base of the primary stem, the second of these arises in precisely the same way as the first, and almost simultane- ously. It is, however, always smaller than the latter in the two species in which I have observed it; especially so in A. medeoloides, where it might easily be mistaken for a leaf belonging to the large rhizome bud which it also subtends, were it not for the evidence afforded by its position and earlier origin than the bud which appears to bear it (Plate LIII, Fig. 14). This second kataphyll is placed at right angles to the plane in which both the cotyledon and the first kataphyll lie, as shown in the accompanying outline drawing (Fig. 4). 13 The remainder of the plumule grows upwards and forms the first epigeous axis, upon which there soon appear the scale-leaves characteristic of such shoots (Plate LIII, Figs. 12 and 13). These scale-leaves arise close to the apex, two or more being always present as a protecting cap upon it (Plate LIII, Fig. 6). At first they appear almost opposite, but as the stem elongates they become separated by relatively long internodes, and assume their normal position in 4 spiral. They differ from the basal kataphylls in not being amplexicaul and in having much smaller axillary buds which often remain undeveloped in the lower part of the shoot, but in the upper produce lateral branches bearing. cladodes, or even cladodes directly, but never shoots resembling the parent axis (Plate LIV, Fig. 16). The opinion of certain writers already alluded to, that the single sheathing kataphyll, which had been observed in advanced seedlings of A. officinalis, should be regarded as a second cotyledon because it arose at the base of the primary axis immediately opposite and at the same level as the cotyledon, falls to the ground for two reasons. Firstly, as has been shown, it is only after the commencement of germination that the development of this leaf takes place ; there is absolutely no trace of it before that time. It cannot, to my mind, be regarded as the homologue of an organ belonging essentially to the embryonic phase of the plant’s life, especially when what has been already stated regarding the influence of adult structure upon the state of differentiation of the plumule before germination is recalled. Secondly, since we now know that some Asfaragi have two quite similar kata- phylls occupying side by side the same position as the single one of A. officinalis does ; and since there is no difference what- ever in their mode of origin and subsequent behaviour, we must give up the claims of both, or be prepared to gift certain species with no less than three cotyledons. Some even of the earliest investigators, such as Mirbel (1) and Braun (2), seem to have thought that the study of Asparagus seedlings helped to settle that vexed question, the homology of the cotyledon. If the secondary and all subsequent axes bore two sheathing basal scale-leaves, while the primary one—at the base of which is attached the cotyledon—had but one, did not this go to support the view that the cotyledon was the first leaf of the stem below which it arose ? It would thus correspond to the first of the pair of leaves of the succeeding axes, and could be called quite correctly a “‘ seed-leaf.’’ This idea is of course no longer tenable when it is known that in such species as A. plumosus and A. medeoloides the shoot derived from the plumule, as well as those which follow possess a similar pair of these kataphylls. 14. THE GENERA Ruscus, DANAE, SEMELE. The development of the embryo being so characteristic, and the features of germination so constant in the six species of Asparagus studied, it was decided to make an examination of those genera—Ruscus, Danae, and Semele—which in Engler’s “Pflanzen-familien ” are placed, along with Asparagus, in the sub- division Asparagee of the family Liliacee. Like the latter genus they are characterised by the reduction of the leaves to minute colourless scales, by the presence of remarkable cladodes, and Fic. 5.—A, Longitudinal section passing through the plumule of an embryo of Ruscus aculeatus, Linn.

Cot., cotyledon; E., embryo; by the possession of a hypogeous sympodial rhizome. One would thus expect to find little or no difference between the anatomy of their embryos and young seedlings and those of Asparagus. There are, however, certain modifica- tions in structure observable which are worthy of note, and I shall chiefly confine myself here to a short account of these. Through the kindness of Professor Bayley Balfour I obtained good seed of the following plants :—Ruscus aculeatus, Linn. ; R. Hypophyllum, Linn.; Danae Laurus, Medic.; and Semele androgyna, Kunth. These were germinated, sectioned, and 15 examined in the same way as was done in the case of Asparagus The fruit and seed in these genera are like those of Asparagus, except that the seed-coat is commonly of a paler colour. Both micropyle and hilum are visible ; they occupy the same positions and have the same appearance as in that genus. The embryo is shorter and broader (A, Fig. 5) but its orientation is quite similar (C, D, Fig. 5). Its various parts, including the plumule (Plate LIV, Figs. 19 and 24), closely resemble those of Asparagus, only that the number of vascular bundles in the cotyledon is greater (Plate LIV, Fig. 17), while the tissues of the primary root are perhaps slightly less clearly differentiated (Plate LIV, Fig. 18). In all three genera the features of germination are remarkably alike, so much so that it will be unnecessary to fully describe and illustrate more than one ; for this purpose Ruscus aculeatus has been chosen. Observed from the exterior, the only differ- Fic. 6.—Polygonatum 6 ae Desf. Seedlings at various sina ne. develop- ment, showing the — h of the tuberous hypocot yl, &c. (All x3.)

I have not followed the growth of seedlings to maturity and so cannot say exactly how many of these basal kataphylls—separated only by short internodes—are normally produced, but I have before me a section of Semele androgyna in which no less than eight are shown, each with a very large axillary bud. In Ruscus a smaller number seems to be typical, and the first apparently subtends no bud ; while here, as in the other two genera, both the epicotyl and the internodes between the kataphylls elongate a little, especially in deep-sown seedlings (Plate LIV, Fig. 23). In longi- tudinal sections of the young seedling it is seen that the greater part of the plumular meristem is devoted to the formation of leaves, and that these sheath the axis more completely than in 16 Asparagus. The sheathing bases may be relatively large as in Ruscus (Plate LIV, Fig. 21), or smaller as in Semele (Plate LIV, Fig. 25); but they are only produced when the leaf has become well developed, being represented before then by a narrow band of meristematic tissue passing round the axis outside and at the base of the succeeding leaf, and distinguishable from a leaf-prim- ordium by the absence of the well-marked vascular bundle which passes out into the latter (Plate LIV, Fig. 22). With these ex- ceptions, the rest of the Asparagee differ but little from the genus Asparagus. THE GENUS POLYGONATUM. I have included a few drawings of Polygonatum lati- folium, Desf., to illustrate an interesting modification in the development of the seedling, which I think further investiga- tion will prove common to the genus. The structure of the seed and embryo is similar to that of Asparagus medeolotdes Fic. 7.—Polygonatum latifolum, Desf. hte oy — of seedlings es the plumular eee ee ung; B, an advanced ae cs 2 Tite of cot Siyisden ; Ap., shoot apex » thizome buds i = the pat of t the kataphylls ; £ f172; &e. }; easlipil 03 2nd, &c.); Hyp., hypocotyl; Pr., primary root; r.2, secondary foet s-she( ae, 2: &e) ), sheathing base of leaf A1St; ore, Ge.) > Tht.

The interest- ing point, however, is that the hypocotyl—which in these plants remains almost undeveloped—becomes in this case enlarged into a tuberous structure, and thus helps in the formation of the first joint of the thick, fleshy, sympodial rhizome typical of the genus Polygonatum (Fig. 6). The growth of the plumule resembles that of Ruscus, but the epicotylar and few succeeding internodes are rather more elongated and fleshy ; while the kataphylls are 17 a little more prominent. Some five of these leaves are produced upon this shortened underground part of the primary axis, which then elongates to form an aerial shoot, leaving them at its base (Fig. 7). In the axil of each lies a large bud; that of the fifth continues the growth of the main rhizome, while those of the preceding four—if they develop further—give rise to its lateral branches. THE GENUS SMILAX. Two species of Smilax were examined—S. herbacea, Linn., and a plant of uncertain identity. In these the seed and its germination were indistinguishable, exhibiting the following peculiarities as compared with Asparagus. The micropylar region of the seed forms a small protruding point, in which Fic. 8.—Smilax,Sp. Seedlings in various stages. Cot., cotyledon; Cot. sh., sheathing base of cotyledon; f.

I have been unable to detect any differentiation in these embryos, several of which have been cut and examined, though this may be due to the difficulty of correctly orientating so small a structure when embedding it. I am, however, inclined to believe that, even in “ripe” seed, the embryo is at a very early stage in its development, and remains so during its resting period within the seed. The cotyledon of quite young seedlings is so very much larger than that region of the minute embryo that I think it probable that between sowing and actual germination—as this term is usually applied—the embryo undergoes further growth, as has been observed in the case of Juncus and other plants. It will be seen that the appearance of seedlings at various stages (Fig. 8) at once recalls the genus Asparagus. As one ; q a a 18 would expect in plants, such as Smilax, with large leaves and long climbing stems, both are well represented in the plumule of a young seedling (Plate LIV, Fig. 26). The first leaf—a kataphyll— is rapidly developed and appears from the sheath of the cotyledon before the primary axis (C, Fig. 8), which soon follows (E, Fig. 8). This is the only basal scale-leaf produced, and subtends a very large rhizome bud exactly like that of Asparagus (Plate LIV, Fig. 27). Moreover, both the hypocotyl and the epicotyl remain, as in that genus, quite unelongated. SUMMARY. Asparagus (p. 4). 1. The embryo is long and narrow, straight or somewhat curved, and consists of a ae cotyledon, a plumule, and a well- differentiated radicle (p. 6 2. The plumule lies we the root-pole, and i is quite undiffer- entiated into leaf-primordia and axial portion. It consists of a dome-shaped patch of meristematic tissue, and occupies a lateral position, slanting downwards and outwards (pp. 6 and 12). 3. The vascular systém of the embryo seems variable, both in different species and different individuals (p. 7). 4. The type of germination found throughout the genus is remarkably constant. It is characterised by the stout persistent tap-root; by the dominance of the axis; by the failure to elongate of hypocotyl, epicotyl, and sometimes even the inter- node above the latter; and by the presence of hypogeous kata- phylls at the bases of the shoots, in whose axils large rhizome buds arise (p. 8). 5. The mass of the plumular meristem gives rise to axis, the basal kataphylls being derived from a small portion at its outer margin (p. II 6. Each kataphyil btends asingle rhi bud (pp. roand 12). 7. The species ‘examined can be divided into two groups— those having at the base of their primary axis one, and those having two kataphylls (pp. 5, 9, and 12). The apex of the shoot is always protected by two or more scale-leaves. In its upper part the cladodes arising in the axils of the leaves develop almost as rapidly as the leaves themselves (pp. 10 and 13). g. The elongation and branching of the sympodial rhizome is brought about by the rhizome buds (p. ro). 10. The primary root acts as a pull-root, and sometimes as a storage-root (p. 10). 19 11. The statement that the first kataphyll represents a second cotyledon is disproved by the fact that it only makes its appearance after germination, and that some species have two (p. 13). 12. For the second of the above reasons it alsé follows that the anatomy of Asparagus seedlings does not support the view that the cotyledon is a leaf (p. 13). Ruscus, Danae, and Semele (p. 14). 13. The embryo is shorter and broader but in all other respects resembles that of Asparagus (p. 15). 14. The germination is almost identical in all three genera, and differs from that of Asparagus in the larger number of more sheathing basal kataphylls ; in the less dominant axis; and in the slight elongation of the epicotyl and succeeding hypogeous internodes of the primary axis (p. 15). ' Polygonatum (p. 16). oe ss 15. The germination much resembles that of Ruscus ; the most interesting deviation is the part played by the tuberous hypocotyl in the formation of the fleshy rhizome (p. 16). Smilax (p. 17). In ripe seed the embryo is very minute sid apres undifferentiated (p. 17). 17. The germination very closely resembles that 3 Asparagus ; 17). axis and leaf are, however, about equally developed (p. 1 PREVIOUS PUBLICATIONS RELATING TO THE GERMINATION OF ASPARAGUS.

THE principal aim in sylviculture, as well as in the sister sciences of horticulture and agriculture, is not merely to grow | plants, but rather to direct their development in such a way that they will produce the most useful material. This necessitates a certain amount of interference with the plant’s natural course of development and habit of life. It is not always possible to avoid placing the plants in somewhat unnatural positions, and, again, a large number of individuals of the same species are frequently grown in close proximity to each other. Cultivated plants are thus not under the same conditions as those which grow naturally. The less we interfere with nature and allow the plants to grow under as natural conditions as artificial cultivation will permit, the better will be the results. This is a fact of great importance, especially in sylviculture, where the trees require a long period in which to complete their develop- ment. In horticulture and agriculture the case is slightly different. Here the plants are not so long lived, and consequently not exposed to such a prolonged strain. Under cultivation, plants tend to become less resistant in regard to their natural enemies in the shape of insects and fungi. Consequently they are more liable to be affected by epidemic diseases which may cause large pecuniary loss not only to the cultivator, but to the country at large. ‘: Plant pathology is concerned with the disease of plants just as medicine and veterinary science is concerned with the cure of disease of man and animals. The plant pathologist’s scope is, however, more limited. Individual attention cannot be given to each plant in a forest, and consequently the method by which success is most likely to be attained is that of pre- [Notes R.B.G., Edin., No. XXI, August 1909.] 24 vention. That is to prevent the outbreak of disease in the first instance, or, if it has once appeared, to prevent its further spread. Though the rules and precautions to be adopted are simple enough, still they are extremely difficult to put into practice. It is only within recent years that cultivators in general are beginning to realise how infectious many plant diseases are, but even yet in the majority of cases it is only after a disease has become epidemic and has occasioned considerable and _ irre- parable damage that the advice of the plant pathologist is sought. There are cases enough on record where valuable crops can no longer be cultivated owing to the ravages of disease which might have been prevented from occurring at all, or at least checked or considerably modified in its early stages. Such has been our unfortunate experience with the European larch. As the result of planting in unfavourable soils and situations, its predisposition to canker caused by Peziza Willkommit has been so much increased as to very seriously interfere with its pro- fitable cultivation. It is therefore not surprising that attempts have been made to find a substitute in the shape of some other species of larch which would resist the ravages of the canker fungus. Within comparatively recent years two species have been introduced in the hope that they would be less liable to attack, if not immune from the disease. These two species are Japanese larch (Larix leptolepis) and the western larch (Larix occidentalis). e western or occidental larch was discovered in the year 1826 by Douglas, but over fifty years elapsed before it was introduced into this country. For some reason or other, possibly the difficulty in securing seed, and consequently through the scarcity of plants, this tree has not become very widely known in Britain. Mr. H. J. Elwes, after several attempts to secure a supply of seed, was finally successful in securing a small quantity in the year 1903. This he distributed to arboriculturists in many parts of the country in the hope that this species would be “‘ less liable to the attack of P. Willkommit than the common larch.”” Speaking of the germination of the seed which he dis- tributed, Mr. Elwes says: “ The seedlings raised in 1904, from the seed which I distributed, have grown in several places, best perhaps at Murthly, under the care of Mr. Lawrie, where in September 1906 I saw some hundreds thriving very well, though not so large as the common larch of the same age.” In the winter 1908-09 two specimens were sent from Murthly to the Royal Botanic Garden, one of which had, unfortunately, developed unmistakable symptoms of attack by P. Will- kommit. This plant is shown in Plate V, Figs. 1 and 2. The cankered portion, as will be seen in Fig. 1, is situated at 26 to its vast importance. A large amount of close observations and experimental work is necessary in order to decide which new species are likely to give better results than those at present under cultivation, and no doubt experimental forest-gardens and demonstration forests would provide a means of answering many of those highly important questions.

Research on the Proteolytic Enzymes in Fungi and Bacteria. ise 4 ROBERT M. WILSON, B.Sc., CARNEGIE SCHOLAR. THE presence of proteolytic enzymatic activity has been demonstrated in members of practically all the groups of the plant kingdom by several investigators, among them :— Wurtz and Bochut, who discovered a trypsin-like ferment in Carica papaya. Tommasoli and Dacommo, who found a proteolytic enzyme in Anagallis arvensis. Markano, who isolated the ferment bromelin from Ananas. Goroup Besanez, who found pepsin in the germinating seeds of Vicia, Cannabis sativa, Linum usitatissimum. Green, who isolated from the germinating seeds of Ricinus a trypsin-like ferment, which had the power of converting albumin and globulin into peptone and asparagin. For the first definite knowledge of proteolytic enzymatic activity in bacteria, however, we are indebted to Bitter, who in 1887 isolated from cultures of Vibrio cholere-asiatice and Vibrio Finkler-Prior, a ferment which was capable of dissolving gelatine and fibrin. The fundamental work in connection with the activities of proteolytic enzymes is that of Fermi, who, in his various experi- ments with members of the higher and lower forms of plant life, gives many instances of proteolysis. These results and those obtained by other observers, com- bined with the general indications of the almost universal occurrence and activity of proteolytic enzymes throughout animal and vegetable life, would seem to render a systematic search for such enzymes amongst fungi and bacteria desirable, in order to ascertain, if their presence may be regarded as essential to fungoid and bacterial life, the functions they have in con- nection with such life, and the manner in which, as well as the conditions under which, these are carried out. I have been fortunate enough to obtain a Carnegie Scholarship for the purpose of a research in this direction, and have been [Notes R.B.G., Edin., No. XXI, August 1909.] 28 granted also the privilege of working in the Mycological Depart- ment of the Heriot-Watt College, Edinburgh, under its director, Dr. Westergaard. I wish to express here my sincere thanks for this. In the two reports which follow will be found an account of the methods employed by me and the results which I have obtained in determining whether or not proteolytic enzymatic activity is generally present in fungi and bacteria. FIRST REPORT. Up to the present I have confined my attention entirely to the higher fungi, as these can be most readily obtained in September and October growing in large numbers in woodland and meadow, and I have left the lower forms, which can be cultivated in the laboratory at any time for subsequent experi- ment. . Towards the end of September the following species of fungi were collected :— . Agaricus melleus, A. sulphureus, A. squarrosus, Merulius lacrymans, Polyporus betulinus, P. sulphureus, P. squamosus, Lactarius insulsus, L. cilictoides, Russula Clusii, Cortinarius sp., Boletus sp. Preparation of Enzyme.—Each species of fungus was ground up separately in a mortar with sand and sufficient water to form a thick paste. After a homogeneous mixture had been obtained more water was added, and again the contents of the mortar were thoroughly mixed. The contents were then filtered, and to the filtrate was added twice its volume of absolute alcohol. On the addition of the alcohol a precipitate fell, which was filtered off, washed with alcohol and ether, and dried in a vacuum desic- cator over concentrated sulphuric acid at room tempera‘ure. My intention was, as stated in the account of the proposed work, to determine the proteolytic activity in each species of fungus by allowing the enzymatic preparation to act upon wheat protein, which is insoluble in water and soluble in 55 per cent. alcohol. The method used by Kjeldahl and afterwards by Weise to obtain this protein—by extracting wheat flour with 55 per cent. alcohol and freezing the extract,—gives a very small yield, and is in addition rather long and troublesome, and the following modification suggested by Dr. Westergaard was therefore adopted :— Preparation of Protein.—Gluten flour was extracted with three times its weight of 55 per cent. alcohol at room temperature 29 for twenty-four hours. To the filtered extract an equal volume of ether was added, which caused a heavy brown semi-liquid substance to separate out. This substance was, by treatment with cold absolute alcohol during several days, converted into a hard white brittle mass, which, on being suspended in cold water became soft and spongy, and again hardened, when placed in alcohol. By thus alternately washing with water and with alcohol, the preparation was purified as far as possible, and ultimately, after the last treatment with alcohol, it was washed with ether, dried in a vacuum at room temperature, and ground to powder. Estimation of Nitrogen in Protein.— 1 gm. protein was boiled with 20 c.c. concentratd sulphuric acid (nitrogen free) and potassium sulphate till the liquid was quite clear, when potassium permanganate was added in excess and the ammonia estimated by distillation with caustic soda. RESULTS.—Ex pt. 1. 15°9 per cent. nitrogen. Expt. 2. 16 ” ” These results are slightly lower than those obtained by Kjeldahl, whose protein contained 17°25 per cent. nitrogen. This powder was then used for testing the proteolytic activity of the fungi or preparations of these in the following manner :— In each case three flasks were employed, each containing accurately the same quantity of protein, enzymatic preparation, and water. To one of these flasks tannic acid and a trace of sodium acetate were added at once, whilst the other two were placed at 50° C. for twenty hours, when they each received the same quantity of tannic acid solution and sodium acetate as the first one. The effect of the tannic acid is to precipitate the proteids, proteoses, and peptones present so that the filtrate will only contain nitrogenous compounds of a simpler constitution than these. The amount of nitrogen found in the filtrates from the flasks, which were kept at 50°C., compared with that contained in the filtrate from the flask that was precipitated at once, will be an indication of the degree of proteolytic activity, and the results obtained expressed in c.c.’s of deci-normal ammonia may be used for comparison if the conditions as time, temperature, concentration, etc., are kept uniform. Preliminary Experiments.—In order to test the methods, the following three determinations were carried out, using the preparations obtained in the manner already described from :— Polyporus sulphureus, P. squamosus, Merulius lacrymans. In each case *5 gm. of the enzymatic preparation was dis- Pas ie aa 30 solved in 20 c.c. water and filtered. Five c.c. of the filtrate were placed in each of three 100 c.c. flasks, along with ‘2 gm. of the. protein and 25c.c. of water. The flasks were treated as described above,and after precipitation with tannic acid, made up to 100 c.c. with water, and the contents were filtered. The nitrogen was in each case determined in 30 c.c. of the filtrate, with the following results :— POLYPORUS SQUAMOSUS.

The accuracy was not satisfactory, especially in the case of P. sulphureus, but this was found to be due, not to the method, but to minor errors in the manipulations; in all the subsequent determinations the results of the duplicates have come out practically the same. In order to test the effect of a slight trace of acid or alkali on the activity the following experiment was carried out with the enzymatic preparation obtained from P. squamosus. ‘5 gm. of the preparation was dissolved in 30 c.c. water, filtered, and 3 c.c. of filtrate put into each of nine test tubes along with ‘2 gm. of protein. To the first three tubes hydrochloric acid was added, so that in 6 c.c. of the resulting solution the acidity would be equal to ‘xr per cent. To the second three tubes sodium carbonate was added, so that in 6 c.c. of resulting solution the degree of alkalinity would be equivalent to that of acidity in the first three. To the last three tubes 3 c.c. of water were added. 31 Each series of three tubes was then treated in the same manner as described in the case of P. sulphureus, etc., and the following results obtained :— AcIp SOLUTION.

The several species of fungi mentioned at the beginning were examined in the following manner :— 1. Auto-digestions. 2. Preparation of enzyme. 3. Direct examination of the juice of the fungi. 1. The auto-digestions were made chiefly in order to have material to fall back upon for confirmation of results, and were carried out in the following way :— In the case of each fungus two equal quantities were weighed out, one portion was boiled for a few minutes, both lots were then ground up separately in a mortar with sand and an equal volume of water till a homogeneous mixture was obtained ; they were then bottled and shaken up with a little toluol. 2. The preparation of the enzyme was carried out as already described. 3. Whilst the above-mentioned preparations were laid aside to be used afterwards for a detailed examination of the nature of each enzyme, the proteolytic activity of each of the fifteen 32 species was tested by using the juice pressed from the fresh fungi Fifty gm. of each of the species were ground up with sand and a few c.c.’s of distilled water, filtered, and the filtrate made up to 100 c.c. These liquids were then used for experiment on the lines described above in the case of P. sguamosus. In each case nine tubes were used, making 135 in all, which were divided into lots of three flasks each. The first three flasks each received 8 c.c. of the fungus juice and 22 c.c. of distilled water. The second three flasks each received the same amount of juice and so much sulphuric acid and water to bring the mixture to a total volume of 30 c.c. containing so much acid that the total acidity corresponded to ‘1 per cent. sulphuric acid. The third set of three flasks were made up as above, with the sole difference that sodium carbonate was used instead of sulphuric acid in quantities to make 30 c.c. of the liquid have a degree of alkalinity exactly equivalent to the acidity of the previous lot. After the tubes were all ready, ‘2 gm. of the protein was added and the digestions carried out at 50° C. for four hours, when the proteids, peptones, and proteoses, etc., were precipitated, leaving amino acids in solution. SECOND REPORT. As mentioned in the first report extracts of fifteen fungi were brought into contact with protein. In each case three sets of three tubes were used. In one set the extract was taken directly from the fungus; to the extract in the second set was added hydrochloric acid to such an extent that the total acidity was ‘1 per cent.; to the extract in the third set sodium carbonate was added, so that the resulting alkalinity was equivalent to the degree of acidity in the second set The digestions of the protein were carried out at 50° C. for four hours, when the peptones, etc., were precipitated, leaving amino acids in solution. The liquid was then filtered and evaporated down with a little concentrated sulphuric acid till fumes of the latter were observed to come off, when other 20 c.c. were added and the flask heated till the contents were clear. Potassium perman- ganate was then added in excess to oxidise any organic material present. The flasks were then washed into larger ones, and concen- 33 trated caustic soda added when ammonia was distilled over and absorbed by deci-normal sulphuric acid. The results obtained are found in the following table whose figures denote tenths of 1 c.c, deci-normal ammonia (Flasks (1) and (2) are duplicates, flask (3) is a blank.) AGARICUS AGGREGATUS.

That proteolytic activity is present in every case. 2. That the proteolytic activity in the acid medium is dis- tinctly highest in three, viz.:—Agaricus aggregatus, Peziza, and No. 27. 3. That the proteolytic activity in the alkaline medium is distinctly highest in one, viz. :—Agaricus squarrosus. 4. That the proteolytic activity in the media to which neither acid nor alkali were added is distinctly highest in six, viz. :— Agaricus A., Amanita vaginatus, Agaricus melleus, Lactarius insulsus, Russula cyanoxantha, and Polyporus betulinus. 5. That proteolytic activity is greater in acid than in alkaline media in three, viz. :—Lactarius cilicioides, Agaricus C., and Agaricus arvensis. 6. That proteolytic activity is increased by both acid and alkali in Agaricus aggregatus. 7. That the proteolytic activity is practically the same in all three media in the case of Agaricus B. Having finished this experiment with the above members of the higher fungi, and made enzymatic preparations from several others which have yet to be examined, pure cultures were made of the following lower fungi and bacteria :— Mucor Mucedo, Mucor spinosus, Mucor racemosus, Asper- gillus niger, Aspergillus glaucus, Aspergillus oryz@, Momilia 36 candidia, Chalara mycoderma, Oidium lactis, Cladosporium herbarium, Bacillus subtilis, Tyrothrix tenuis, Bacillus pro- digiosus, Streptothrix lactict acidt. After getting pure cultures of the above fungi, ten flasks containing sterile malt extract were inoculated with the ten orms. The pure cultures of the bacteria were introduced separately to flasks containing sterile glucose peptone (1 per cent. peptone, 4 per cent. glucose). When the development had proceeded sufficiently far the fungi or bacteria were separated from the nutrient medium, and both organisms and media tested for proteolytic activity. In the case of the fungi the malt extract was filtered off and the mass of fungus mycelium washed a few times with distilled water. The fungus was then ground into a fine state with sand and water, and the extract filtered off. Twenty-five c.c. of the filtrate were put into each of three flasks containing ‘2 gm. protein. To one 5 c.c. of a 20 per cent. solution of tannic acid was at once added, and all three flasks incubated at 47° C. for five hours. After this time the other two flasks received 5 c.c. of tannic acid ; all three made up to 50 c.c. and filtered. enty-five c.c. of the filtrate were evaporated down with a little concentrated sulphuric acid till fumes of the latter came off, when other 20 c.c. were added, and the flasks heated till the contents were clear, when distillation was carried out in the way already mentioned. The malt extract was tested in the same manner as the mycelium extract, 25 c.c. being use So far the experiments with Aspergillus miger and Clado- sporium herbarium have been completed with the olewte results :— (Figures represent tenths of I c.c. deci-normal ammonia.)

This indicates that the fungus during its growth excretes into the medium, in which it is situated, a proteolytic enzyme, which brings the complex proteids into a fit state for assimilation by the organisms. In experimenting with Bacillus prodigiosus, the bacteria were separated from the medium by means of a centrifugal machine, and ground in a mortar with solid carbon dioxide and ether. Tenc.c. of distilled water were then added, and 3 c.c. of the mixture put into each of three flasks with ‘2 gm. protein, and the experiment carried out as in the other cases. The medium was filtered through a Chamberland filter in order to get rid of the remaining bacteria, and then used for the digestions in the usual manner.

Meyer. BY BERTHA CHANDLER, M.A., B.Sc. With Plate LVII. UTRICULARIA PREHENSILIS—a sub-aquatic species found in various localities in Tropical and South Africa, and Madagascar— is of considerable interest, as it presents many important differ- ences from such truly aquatic species as U. emarginata, recently described by me.* The material used in the following description was grown from a seed taken from the herbarium by Mr. L. Stewart, Foreman of the Glass Department, Royal Botanic Garden, Edinburgh. He made the following notes: ‘“ Sown in the last week of June the seed germinated in the second week of July 1909. The first flowers appeared on the first of June 1910. By October a mass of flowering material was obtained.” Natural pollination and fertilisation are not so easy or so speedy processes in this as in other species of Utricularia, but some seed has been procured through artificial pollination, sufficient to give promise of a satisfactory examination of the germination later on, as well as of the determination of the position of the species in Gliick’s Classification. 7 In its general appearance Utricularia prehensilis (Fig. 1) presents some striking differences from the aquatic species, for its leaves are riband shaped, not terete and linear like those of U. vulgaris, emarginata, and others. The riband leaves float on the surface of the water, which covers the mud in which the plant thrives. The flower-stalks are aerial, rising to a considerable height, and, as the name of the plant suggests, twine round a support. The direction seems always to be dextrorse. A short general description of the plant, with figures, is given by Stapf}, and he mentions that this species is * Chandler in Ann. Bot., xxiv (1910). : +Gliick, Biologische und morphologische Untersuchungen iiber _Wasser-und Suiimpfgewachse, Teil ii. Jena, 1 t Stapf in Hooker’s Icones Plantarum, t. 2798. (Notes R,B.G., Edin., No. XXII, November tgr1-] 40 CHANDLER—UTRICULARIA PREHENSILIS. known under various synonyms—U. lingulata, U. hians, U. madagascariensis. : FLOWER STALK.—The origin of the flower stalk of U. pre- hensilis does not differ from that of U. vulgaris. It bears also at its base a mass of water shoots, leaves, and rhizoids. The flower shoot is twining, and the average length about 25 cm., sometimes longer. The flowering is more profuse than in U. vulgaris, and the flowers (see Fig. 1 and Stapf’s figures*) are yellow incolour. At the base of a flower stalk we find, as in other species of Utricularia, a number of rhizoids (Figs. 2 and 3). A limited number, usually three or four, are to be found also at some distance up the stalk. The rhizoids in U. prehensilis are not so rudi- mentary as in U. vulgaris, but are fairly well developed. The difference in habitat in the two species would account for the fact that in U. prehensilis the rhizoids are more developed, their use in the greater sub-stratum of mud being very much greater. As Gliick ~ has pointed out, the anchoring function of rhizoids is, to a large extent, lost in wholly submerged species, and the development of these organs is consequently not so great as in the sub-aquatic species. The rhizoids in appearance (Fig. 4) are very similar to those of U. neglecta figured by Gliick, ¢ but whereas in U. neglecta the leaves and rhizoids are alike, in U. pre- henstlis the appearance of the leaves, which are long and flat, in no way resembles that of the rhizoids. The rhizoids are divided into segments, the usual number being nine or ten on each side. The segments are simple, straight, and usually undivided, though occasionally at the base of an older rhizoid, division of the segment itself takes place (Fig. 4a) giving the rhizoid of this species thereaaiee general appearance of that of U. neglecta. The rhizoid segments are given off regularly and alternately at-right angles to the main axis. Unlike U. vulgaris the tips of these segments do not possess circinate ptyxis, but are straight like the growing points of the water shoots. The segments are covered entirely with glands, except at the very tip and base (Fig. 4). Glands also are present at intervals on the main portion of the rhizoids. These thizoids measure some two to three times the length of the rudi- mentary rhizoids of U. vulgayis. Whereas, too, in this latter species, metamorphosis of the rhizoids into ordinary water shoots is common, in U. prehensilis the rhizoids are organs apart from the water shoots, and in no case was metamorphosis observed. MorPHoLocy.—In diameter the flower stalk is about 1=1.5 mm., and is characterised by a reduction of aerenchyma compared to the water shoot. The amount of aerenchyma is naturally greatest at the base of the flower stalk which is under water. * Stapf in Hooker's Icones Plantarum, t. 2768. ¢ Glick, loc. cit. + Glick, tot. oft, «Tata, CHANDLER—UTRICULARIA PREHENSILIS 4t A section across the middle of an aerial flower stalk shows (Fig. 5) a distinct epidermis, composed of large cells somewhat thickened on their outer walls, bounding the section. A small amount of aerenchyma and large round cells, loosely arranged, form the cortex. The endodermis is composed of large clear cells thickened on their radial walls. A ring of xylem surrounds the pith with small scattered patches of phloem. There are also one or two irregularly distributed patches of vascular tissue in the ground tissue, as in U. emarginata * and U. brachiata.t The pith cells are small in the vicinity of the xylem ring, but very large towards the centre of the section. As well as rhizoids, a great number of ordinary water shoots, bearing leaves and bladders, are to be found at the base of an aerial flower stalk, and the leaves are often found springing immediately from the base. In structure the water shoots are simple, having a central vascular strand, surrounded by air tissue and epidermis (Fig. 7a). As in all other parts of the plant, the water shoots are covered at intervals with small projecting: glands. The leaves are given off as branches of the water shoots. At their base they do not differ in any respect from the shoots them- selves, but when the flattening of the leaf begins, the main nerve divides into three, so that a section of a leaf shows three vascular strands surrounded by air tissue, and an epidermis composed of slightly thicker and polygonal rather than brick-shaped cells, as at_ the base, or in a section of the water shoot (Figs. 6and 7). Stomata’ with two guard cells are found at intervals on the leaves with the glands. | The bladders differ in shape from those of U. vulgaris (Fig. 8). Their origin and development are as in other species of Utricularia, each one arising as a roundish knob on a stalk, which is compara-. tively long when fully developed. The bladders of U. prehensilis do not possess hairs at the mouth, but two horn-like elongations of the bladder itself (Fig. 8a). The interior of the bladder is characterised by the absence of quadrifid processes, and is covered only with bifid processes (Fig. 9). The collar is densely covered with stalked glands all of the same shape, while other glands, bicellular in construction, form a transition near the exterior to the pro- jecting glands without stalks, with which the whole exterior of the bladder and the stalk is covered, as are all other submerged parts of the plant. Inside the bladder, decayed brown matter is found, but no distinct entire micro-crustacea. The fact that the bladders of this species are sunk in mud, and therefore more liable to decay, would explain this. * Chandler, in Ann.

DONATIA NOVAE-ZELANDIAE, Hook. f., is a little cushion plant of moss-like habit, growing on the heights of New Zealand and Tasmania. With Donatia fasicularis, Forst., found in antarctic America, it forms an isolated genus Donatia, the systematic position of which has been much debated. Hooker,* who first described it, referred the genus to Saxifrageae. At the same time he pointed out that the insertion of the stamens within an epigynous disk, the extrorse anthers, and the pendulous placenta- tion were characters which pointed to an affinity with Stylidieae. Subsequently Von Mueller ¢ definitely included the genus in the Stylidieae. Engler,t however, retained it in Saxifragaceae as a special tribe, the Donatieae, of his larger group the Saxifrag- oideae, and Schoenland § also definitely excluded the genus from Stylidiaceae. More recently Mildbraed,|| following the lead of Von Mueller, has taken Donatia to be a constituent subfamily, Donatioideae, of the Stylidiaceae, which otherwise includes the subfamily Stylidioideae only. We may admit with Mildbraed that the position of the Stylidiaceae amongst the Campanulateae is assured, and also that the relationship with the Campanulaceae themselves is perhaps not so close as has been urged. Whether, however, there is ground for saying, as he does, that the Stylidiaceae, as he constitutes it, is to be regarded as a small independent branch of the Campanulateae which has taken origin in the antarctic, is a matter for further consideration. Is his family of the Stylidiaceae really a natural one? The Stylidioideae with sympetalous flowers and a gynostemium, and the Donatioideae with a chori- * Fl. Nov. Zel., eee + Nuov. Giorn. Bot.

Their general habit also is alike. There is no doubt that except for the extrorse anthers the evidence is all in favour of Donatia being placed in the alliance of the Campanulateae rather than . in the family of the Saxifrageae, as was the case in the older classification ; but the justification for Mildbraed’s further step of combining the subfamily Donatioideae with the subfamily Stylidioideae in the subfamily Stylidiaceae is not at all evident. The differences between these two groups seem as great as, if not greater than, those between any of the families of the Campanu- lateae. Compare, for example, the Campanulateae and the Stylidiaceae : in the former we have the flower actinomorphous, 5-merous, sympetalous, except for the 3-merous gynoeceum, the anthers are free, introrse, and there is one style with collecting hairs: in the latter the flower is zygomorphous, 5-merous in peri- anth, sympetalous, and with two stamens united with the style in astylar column. Inrelation to these Donatia shows a flower which is actinomorphous, choripetalous, 5-merous in the perianth, the stamens 2-3 free from the style, and the ovary divided into 2-3 chambers. Such evidence might warrant, surely, Donatia being regarded as a distinct order, Donatiaceae, of the cohort Campanu- lateae, rather than as a subfamily of the Stylidiacea. No observations seem to have been recorded of the morphology of Donatia novae-zelandiac (Fig. 1), andI therefore take opportunity to make known a few facts which I have been able to observe in material of the plant obtained from specimens sent to the Regius Keeper, Royal Botanic Garden, Edinburgh, by Dr. Cockayne, who collected it on the heights of Stuart Island, New Zealand. Srem.—In a transverse section the stem. of Donatia novae- zelandiae shows (Fig. 3) a central mass of xylem with fairly large development of cortex and cork. The pith is relatively small, and composed of large slightly thickened cells. Surrounding the pith is the xylem, composed of regular tracheids—spiral, reticular, and annular. There is little xylem parenchyma. Where a side branch is given off, the xylem tracheids are elongated in a raG@ial direction. Phloem is found in patches around the xylem. An endodermis, of sometimes one distinct layer, sometimes more, of: oblong thickened cells with granular contents, is present. Usually these cells lie adjacent, but often project slightly one towards the other (Fig. 3d). The cortex is largely developed. The cells composing it are round and fairly uniform in size, slightly thickened and loosely arranged with large intercellular spaces, No resiniferous secreting system such as is said to occur em CHANDLER—DONATIA NOVAE-ZELANDIAE. 45 in Donatia magellanica* is visible here. Bounding the cortex on its outer side are two or three rows of cork cells. They are different from those of the cortex, being squarish in shape, with thickened walls, and they are filled with oily and granular con- tents. From the outermost layer, at intervals, obliquely septate hairs are given off, the basal cells of which contain oily and granular matter like the cork cells (Figs. 3 and 4). Harrs.—The characteristic septate hairs of Donaita novae- zclandiae are silky in appearance, and form a dense matting at the base of the leaves which are closely adpressed to the stem. The ends of these hairs are sharp and bayonet pointed (Fig. 4a). The cell forming the point is long. The septa are oblique and distinctly pitted and perforated, slightly overlapping on either side at the junction of two cells (Fig. 40). The cells on either side of such a junction are empty and colourless, but occasionally they arethickened. The hairs are comparatively long, and consist generally of ten or twelve cells. The basal—one to three—cells are cork cells and are quite difierent from the others. They are smaller, have horizontal septa, are brown in colour and have a distinct granular content, a nucleus, and a thickened wall. The lowermost of the basal cells is the shortest, and the others are gradually longer until they merge into the empty, colourless cells (Fig. 4d). The whole structure of the hair is unique, and the presence of the perforated oblique plate-septa may, in a xerophytic herb like Donatia, possibly be for the purpose of water absorption. Among these hairs is found an epiphytic fungus to which I shall refer later. Lreaves.—The leaves are packed closely round the stem, and are densely covered with the silvery grey hairs at the base, which is not narrowed into a petiole. The leaf changes in anatomical character from its base to its tip. _ At the base, where it is attached to the stem, the leaf has an irregular triangular outline, with one vascular bundle in the centre (Fig. 6). The epidermis which bounds the leaf is formed of small, regular cells with a thick cuticle. A few stomata occur on the under surface, and these have no subsidiary cells, differing in this also from what is known of Donatia magellanica.— The mesophyll is not differentiated, the leaf being symmetrical, and consists of slightly-thickened cells, somewhat collapsed to the corners of the triangle. Owing to crushing, these cells are some- times locally thickened and infolded, particularly at the corners, somewhat after the manner, though not to such an extent, as that of the infolded mesophyll of Pinus sylvestris. The vascular bundle is irregular in outline, with no bounding endodermis. The xylem * Solereder, Systematische Anatomie der Dicotyledonen, p. 355. ? Til. 3332 Sent 46 CHANDLER—DONATIA NOVAE-ZELANDIAE. in the centre of the bundle is well marked, as is the phloem which surrounds it. Mucilage cells are abundant. Similar appearances to the foregoing are found from the base of the leaf to about the centre, where the single median nerve divides, giving off two side veins, and thus a section across the centre of the leaf shows three vascular bundles (Fig. 7). The leaf is now more symmetrical in shape, losing its triangular form and becoming somewhat oval. The cells of the mesophyll are large and regular. The bundles are similar to the median nerve in the basal section, but, on the outer side of each bundle, scler- enchyma is developed. Stomata are occasionally found, and mucilage cells are more abundant. As might be expected from the habit of growth, the tips of the leaves differ considerably in structure from the basal and central portions (Fig. 8). This ‘is the exposed part of the leaf, and stomata are very abundant. Passing upwards to the tip of the leaf, the cuticle becomes lighter in colour and very thick, the mesophyll is differentiated into long, palisade cells under the epiderntis and loosely-arranged cells towards the centre of the section, first occupied by three vascular bundles, but later by one, as the tip of the leaf is reached. There is a large amount of = developed on the outside of the bundle. Fumago Donatiae, Chandler.

Hab.—Inter pilos circa caulem Donatiae novae-zelandiae. Intermingled with the hairs of Donatia novae-zelandiae is found the mycelium of a fungus. The fungus is epiphytic, for its mycelium merely twines in and out among the hairs of the stem, and lies on the epidermis, not actually piercing the tissue (Figs. 5 and 9). The filaments of the mycelium consist of thick- walled cells of an intense brown colour (Figs. 5 and 10), and they branch freely—the young branches being delicate and colourless, Bead-like gonidia are found on the mycelium (Fig. roa). We know from De Bary * that a resting mycelium stage and resting gonidia are common in starved specimens of Fumago, Penicillium, and Pleospora. In this and other characters the fungus on Donatia resembles species of Fumago, the soot-fungus. * De Bary, Comp. Morp. and Biol, of the Fungi, Mycetozoa, and Bacteria, } CHANDLER— DONATIA NOVAE-ZELANDIAE. 47 Under favourable conditions the mycelium and the gonidial cells pass from the condition of rest. After one day in water the mycelial threads swelled, and new transparent filaments were visible. After two days in water several of the gonidia had germinated, bursting the thick wall, giving rise to a promy- celium. Although Fumago is classed with the Ascomycetes, its life- history is not yet clear. Fertile hyphae are rarely seen, but in the species on Donatia,; now under notice, twisted filaments, such as are found forming an ascocarp in Penicillium, were ob- served twice. Conjugation of filaments, a feature that is not described in any one of the six species of Fumago mentioned by Saccardo,* is, however, common in the fungus on Donatia (Figs. 10 and 11). Two filaments may be seen lying parallel for the length of several cells, and a protuberance grows out from one cell only of one of the filaments until it reaches a cell of the parallel filament : it then fuses with it, and forms a distinct bridge between the filaments (Figs. toc, 11a). The more common method of conjugation seems to be that a protuberance is formed simultaneously on two cells lying opposite on the parallel filaments, and these, growing out to each other, meet, and the bridge is thus —_ by their union. The variation is quite in accordance with Zopf’s description of Fumago.t De Bary, too, cites this fungus as an example of a cycle of forms still more copious and various than that of Pleospora or Nectria ditissima. - * Saccardo, Syllogae cae iv, 547; xi, 638; xix, 1099. t Zopf, Nova Acta Leopol a, = 48 CHANDLER—DONATIA NOVAE-ZELANDIAE.

BY BERTHA CHANDLER, M.A., B.Sc. With Plate LIX. DEHERAINIA SMARAGDINA was described in 1876 by Decaisne,* and the genus was named by him in honour of M. Pierre-Paul Deherain, aide-naturaliste of the Museum of the Jardin des Plantes. Later, in 1878, we have a description of the plant by Hooker ¢ from a specimen growing at Kew. It thrives best as a stove plant, under warm, moist conditions, for the conditions of its native habitat, near Tabasco, Mexico, are damp and tropical. The particularly fine specimen—a symmetrical, well-formed Edinburgh, has afforded material for the following description :— Deherainia smaragdina, of the order Theophrastaceae, is a much-branched, woody shrub, with twigs, leaves, and flower stalks covered with rusty-brown hairs. The leaves are simple, lanceo- late, 2-5 in. in length, acute, alternate in arrangement, and crowded together at the apex of the branches in the form of a rosette (Fig. 1). They are deep-green in colour, and somewhat coriaceous intexture. On the upper surface the hairs are confined to the mid-rib, while the ventral surface is lighter coloured, and The petiole is comparatively short and also hairy. The flowers are characterised by their green colour, hence the specific name. They arise singly in the axils of the apical rosettes of leaves on a short pedicel, which does not bear prophylls. The calyx is pale-green in colour, hemi- spherical in shape, and five-partite ; the lobes are imbricate, orbicular, coriaceous, membranous at the margins, which are also finely ciliated. The corolla (Fig. 2a, c) is from 2-24 in. in dia- and deeper green in c and coriaceous, pale an ciliated. The throat of the corolla is short, bluish * Ann. Sc. Nat., Sér- 6, tom. iil, p. 139- + Bot. Mag. 1878. {Notes R.B.G., Edin., No. XXU, November rgt!.) 50 CHANDLER—DEHERAINIA SMARAGDINA. and thickly covered with whitish hairs on the dorsal surface. Where the lobes of the corolla unite, occur small, ligulate pro- jections, the so-called staminodes. These are five in number, sub-acuminate, and slightly paler green in colour than the petals. (Fig. 2). The five stamens are opposite the petals; at first closely adpressed to the style (Fig. 2a; b), latér:they bend out- wards, and place themselves against the corolla tube (Fig. 2c, a). The filaments are broad, and united at the base around the ovary ; the anthers are sub-quadrate in shape and extrorse. The con- nective is obtuse, truncated ; the pollen saes are situated at the apex of the anther, and a white, mealy mass, consisting of cellular fibres, at the base. The ovary is flask-shaped, with a long, slender style and discoid stigma. It is unilocular, with numerous ovules. borne on a central placenta. SHooT.—At the close of the flowering season, Deherainia smaragdina begins to put forth numbers of new shoots. These: shoots, like the flower buds, arise in the axils of the apical leaves. of the rosette. The various stages are shown in the figures. (Fig. 3, I-V). The older leaves have been cut off, and their positions are indicated by the leaf scars. These new shoots are very soft, covered with a profusion of silvery-grey hairs, and a number of reddish scale leaves at intervals. In a later stage the leaf-buds have unfolded, and formed the same rosette that characterises the old shoot. The old stem is woody in character, covered with reddish-brown hairs, as indicated, and possessing but few scale leaves. As the young stem, therefore, begins to take on a woody character, its hairs become darker in colour, and the scale-leaves gradually wither away. This can be easily seen in (Fig. 3, V), where the scale-leaves of the older shoot are relatively small and insignificant to those on a younger stem. The internal anatomy of the shoot is interesting. A transverse section (Fig. 4) of an old stem shows a large development of sclerenchyma outside the bundles. The cells of the pith are irregular in size, and are filled with starch. They have thick walls and are pitted. The intercellular spaces are small. The xylem is transversed by numerous medullary rays which are broad, and consist of thin cells elongated in the radial direction. A well-marked cambium occurs between the xylem and phloem. Outside the phloem are patches of sclerenchyma element rays with very small lumen. At the point where the medullary emerge the sclerenchymatic cells are larger, and the circular laminations are crossed by pits (Fig. 5b). The cortex, consisting of thin, regular cells filled with starch, is bounded by the epidermis. The cuticle is remarkably thick and corrugated on its surface (Fig. 5a); this is more clearly shown in a longitudinal section (Figs. 6,7). From the epidermis unbranched hairs are given off. CHANDLER—DEHERAINIA SMARAGDINA. 51 In an old stem these hairs are very markedly thickened, and often swollen at the base (Fig. 6). In a young stem these hairs are replaced by numerous, stalked glands, the heads of which contain cells very similar to the glands which are found on the petals and leaves—though these latter are stalkless. Later on, in the development of the shoot, when the cuticle becomes thick and corrugated, the glands lose their heads, and become thickened to form an ordinary septate hair (Fig. 7). A section of the young shoot agrees in appearance—except for the absence of the marked sclerenchyma—in all respects with a section of an older shoot. LEAVES.—The structure of the leaves of the various repre- sentative genera of Theophrastaceae—Clavija, Jacquinia, Theo- phrastea—has been described already by Votch.* Morerecently he describes f also the leaf of Dehevainia smaragdina, the plant under consideration. His examination gave the following results :— “The epidermal cells are wavy in outline, and the cuticle is striated. Hypoderm is absent. The stomata are elliptical and do not project beyond the surface. Glands are present, with sixteen cells in the head. One-cell-rowed hairs to the length of ten cells are plentiful on the under side. The palisade paren- chyma are only one-rowed, and consist of short cells. The sub- epidermal sclerenchyma are present only in single isolated groups on the upper side, but form large bundles on the under side. Crystals are present in the lower epidermis, The median nerve is simple, surrounded by sclerenchyma, which does not pass through it, and the phloem surrounds the xylem on three sides.”’ examination of the leaf of Deherainia smaragdina confirms these observations generally (Figs. 8 and g). I found, however, that very often the stomata do project considerably beyond the epidermis (Fig. 8a, 92). The glands are stalkless, and are found on both sides of the leaf. The hairs, which are plentiful on the under side, are confined to the portion of the mid-rib on the upper. A transverse section of the petiole, like that of the lamina, shows a large amount of sclerenchyma surrounding the median vascular system, which gradually splits up into three separate strands as the base of the petiole is reached. Roots.—The root-structure of the Theophrastaceae has not been investigated as has that of the stem and leaf,{ but that these organs might present points of interest’ equal to those already described, is shown by the structure of the root of Deherainia smaragdina. : A transverse section (Fig. 10) of a moderately old root shows * Votch, Dissert. Erlangen, 1903. + Engler, xxxiii (1904), Bot. Jahrb. t Votch, loc, cit, Ge 52 CHANDLER—-DEHERAINIA SMARAGDINA xylem in the centre arranged in a somewhat spiral fashion from the centre. The cambium is succeeded by V-shaped patches of phloem, and a many-layered pericycle bounded by the endo- dermis, completes the central stele. The cortex is remarkable for the size, irregular arrangement, and localised division of its cells. The piliferous layer is formed of large cells, which divide in all directions. The root hairs are remarkable for the thickness of their walls, especially at their base. If a section be cut somewhat obliquely across the base of one of these hairs, the thickness of the walls is at once remarked (Fig. 11a). In the young root, the cortical cells are more regular than in the old (Fig. 11). FLOWER.—The external appearance of the flower-parts of Deheraima smaragdina has already been indicated, but one or two additional points may be noted. Typically 5-partite, 6-partite flowers are not uncommon, and, though themselves solitary on their stalks, they are usually developed in pairs in the centre of the rosette, one flower much in advance of the other. The contrast in colour shade between the sepals and petals is well seen in the bud. Not only is the throat of the corolla lined with hairs which slope downwards, but it is thickly dotted with glands visible to the naked eye, as black spots (Fig. 2a, d). These glands are also distributed, though not to such an extent onthe upper portion of the petals. Hooker * has described these glands as “‘impressed dots on the upper surface.”” Otherwise they are unmentioned. The internal structure of the flower has not been hitherto described, but offers many points of interest :— The sepals, though simple in structure, show a well-marked epidermis on both sides, exhibiting a corrugated, cuticular layer on the outer wall. The cells composing the mesophyll are large and homogeneous ; the vascular bundles are numerous, and show distinct xylem and phloem. Glands are present, are on the interior surface, but not in any great number; these sepaline glands, in contradistinction to those at the base of the petals, are all sessile and sunk to the level of the epidermis (Fig. 12a). The petals on the other hand, in cross-section, show the glands more thickly distributed than on the sepals. They occur in all stages, and their development can easily be traced. They origin- ate from an epidermal cell, which divides transversely; the upper cell thus formed becomes the head, and the lower, which takes no further part in the development, remains unchanged. By a series of divisions the upper cell ultimately contains about sixteen cells situated in a radiate manner like the spokes of a ~ wheel. ss | a a * Bot. Mag. 1878, CHANDLER—DEHERAINIA SMARAGDINA. 53 These glands are sunk in the corolla lobes ; their stalks consist of but one cell. Inthe throat of the corolla, however, at the base of the petals, these glands become more numerous ; the basal cell divides to form a stalk of from two to three cells, and the head of the gland is raised some distance above the epidermis (Fig. 13a). Interspersed with the glands are unicellular hairs at intervals (Fig. 130). ~The microscopical character of the stamen is perhaps the most interesting in the whole of the flower. The white mass to be seen on the upper side of the anther is shown under the microscope to be composed of particles of torn fibre, like torn, woody cells. The presence of this fibrous mass had already been remarked by Decaisne * in his description of the plant. eee The pollen sacs are on the under side. The cells of the anther are undifferentiated, except in the region round the pollen sacs themselves, where they are slightly thickened. Between the sacs is an open space, comparatively large, which is filled with acicular crystals in crystal dust (Fig. 140). What the purpose of these crystals are, it is difficult to determine. That they bear some relation to pollination and subsequent fertilisation is doubted, from their proximity to the pollen sacs. The crystals dissolved easily in HCl. The pollen grains are minute and round, and covered with a thick, brown exine, which is ‘minutely fringed. The cuticle of the epidermal cells of the connective is also fringed in the same manner—in appearance like the minute crystal grains on the sporangium of Mucor mucedo. The question of the purpose of the crystals in the anther, those on the pollen grain and on the cuticle of the connective, and the presence of the fragmentary fibrous cells on the upper side of the anther, form a part of the larger problem of the fertilisation of the flower. - The ovary in section (Figs. 15 and 16) shows a central placenta on which are situated the anatropous ovules. The seed and fruit are unknown in Europe, and wherever it has been naturalised. The plant is easily propagated by cuttings, roots being formed at the node without much callus formation. It has already been stated that in the young stage of the flower, the stamens are closely adpressed to the stigma, but at a later stage they fly apart, and stand with their filaments and anthers pressed back against the petals. The full significance of this fact has not yet been grasped, for nothing is known yet as to the fertilisation of Deherainia smaragdina. That the flower is insect-pollinated is evident by its foetid odour, by the presence of glands on the petals and the hairs lining the throat of the corolla. Various attempts were made to artificially fertilise the flower, Experiments were made by transferring the pollen grains +* Decaisne, in Ann, Sc. Nat., sér. 6, tom. iii. pee x eae oe z 54. CHANDLER—DEHERAINIA SMARAGDINA. from one flower in the young stage to the stigma of a flower in a correspondingly young stage; from one flower in a young stage to the stigma of another flower in an old stage, and otherwise. These experiments were, however, put an end to by the close of the flowering season. That the pollen is not sterile is proved by the fact that it germinated slightly in a weak solution of sugar (2 per cent.), also that a ripe seed was obtained, according to Mr. L. Stewart, Foreman of the Glass Department, Royal Botanic Garden, Edinburgh, when pollen was transferred from a Deherainia plant to a Theophrasta. The microscopical character of the stamen is unique in many respects, and offers suggestions for experiments in artificial fertilisation, for which it is hoped there will again be opportunity. So far the pollen of Dehevainia smaragdina has shown itself for the fertilisation of its own species, practically sterile. BIBLIOGRAPHY. SOLEREDER, Syst. Anat. d. Dicot., Pp. : NGLER-PRANTL, Natur.

SCHEUCHZERIA PALUSTRIS. LINN. Scheuchzeria palustris, L. Its occurrence as a British plant, with a fresh record. BY GEORGE W. SCARTH, M.A. With Plate LX. SCHEUCHZERIA PALUSTRIS is associated with Triglochin in the family or tribe Juncagineae of the cohort Helobieae. It is the only species of the genus, and the genus is not particularly like any of its nearest allies. The species is, therefore, somewhat isolated, presumably an old and decadent type. Like many such it has a wide but rather sporadic distribution. Its range extends right round the northern hemisphere, viz., Western, Northern, and Central Europe, Siberia, and North America (Rocky Moun- tains, Labrador to Hudson’s Bay, New Jersey to Wisconsin). In Britain it has been recorded from about nine localities, some of them in close proximity. Our knowledge of it was sum- marised in 1904 by Mr. A. Bennet in the “ Transactions of the Caradoc and Severn Valley Field Club.” The history of the plant is briefly as follows :— In Yorkshire it has been recorded from— Leckby Car (near Boroughbridge).—It was discovered here in 1787 by the Rev. James Dalton, the earliest record for Britain. As late as 1892 Mr. J. G. Baker still recorded it. In 1903 Mr. Fisher wrote that it was extinct, and if there was any doubt as to the matter then, there is now-none, for Leckby Car is drained and planted. | Thorne Moor (near Doncaster).—Discovered in 1832 by Mr. S. Appleby. One plant was found in 1870; it wes sought in vain in 1877-1878; in 1890 a Moss Litter Company leased the moor and removed the peat, and Mr. Lees pronounced the plant undoubtedly extinct. A great fire in 1896, which destroyed 1000 acres of peat moss, made doubly sure of the fact. Wetherby (Mid-West Yorks) —Mr. Bennet noted the following record in Don’s Herbarium Britannicum, issued 1806, “ Marsh near Wetherby, Rev. J. Dalton.” There is no mention of this locality in Lee’s West Yorkshire Flora, and no recent records. {Notes R.B.G., Edin., No. XXII, November 1911.] 58 ScARTH—SCHEUCHZERIA PALUSTRIS. Malton (E. Yorks).—In the Herbarium at the Royal Botanic Garden, Edinburgh, there are specimens in herb. Col. Jas. Brodie, which he had received from the Rev. Jas. Dalton, and which are labelled apparently in Col. Brodie’s own handwriting, ‘Found by Mr. Dalton, near Malton, Yorkshire.” This seems definite enough, and neither Leckby Car nor any other recorded Yorkshire station can be described as near Malton in any sense ofthe word. Strange to say, however, there seems to be no other record for this locality, and, according to Mr. Bennet, ‘‘ two or three good botanists have lived at Malton for many years”’ ; nor is there any mention of Malton in Wilkinson’s account of Dalton’s herbarium in possession of the York Philosophical Society. This might be explained by the fact that these specimens were the last of Mr. Dalton’s stock, as he states in a letter attached to the sheet, the rest having been supplied to Don for his Fasciculi. He may not again have gathered specimens at Malton, when Leckby Car was so much more convenient for him. At any rate, this is a rather problematical record. If it is authentic, we have no knowledge of the exact locality. Mr. Bennet suggests Terrington Car as the only place he can think of; but it can scarcely be supposed that the plant still exists and has escaped observation since Dalton’s time. For Northampton there is one old record. The Rev. M. J. Berkley wrote to Mr. H. C. Watson in 1844 that the plant had been found in a marsh (presumably Everton Car) in the North of Notts. There are no recent records to justify a hope that the plant may still exist there. Shropshire has yielded four sites :— Bomere.—Discovered, 1824, by Mr. J. Jeudwine. In 188z Mr. Beckwith and Mr. La Touche could only find a few plants; in 1892 Mr. Druce, the Rev. E. F. Linton, and Mr T. P. Blunt could find none. It is assumed to be extinct. Shomere.—Adjoining the above locality, where it is said to have been found the same year by the same gentleman. Mr Bennet could discover no records for the site. Welshampton Moss.—In 1866 the Rev. O. M. Fieldon found three specimens here; in 1893 he could not find any, and in 1898 he wrote that he did not think he had seen it there within the last fifteen or twenty years. Ellesmere.—Discovered in 1884 by Mr. Beckwith. In 1892 Rev. E. F. Linton could not find it there. In Cheshire it was discovered on Wybunbury Bog, in 1849, by the Rev. G. Pinder. It was found in 1895 by the Rev. E. S. Mar- shall, though supposed to be extinct, and in 1904 the Rev. W. R. Linton told Mr. Bennet that he had seen it a few years previously, so that at that time there was still a hope that the plant survived ScCARTH—SCHEUCHZERIA PALUSTRIS. 59 in that station. Recent search has caused botanists to fear that there too it has gone. The bog has been partly drained. In 1908 Mr. Druce and Mr. A. J. Evans spent two days at Wybunbury in a vain. search for the plant, and again this year (1910) they spent a whole day looking for it without result. In Scotland, Scheuchzeria used to be found in the White Myre of Methven, near Perth. It was discovered there in 1833 by Mr. Duff. Writing in the Phytologist in 1858, Mr. John Sim says that in June of that year he saw the Scheuchzeria growing luxuri- antly and plentifully, and brought home “a good supply, above three hundred plants.’’ In the next sentence he says “It is nearly done.’’ Mr. Sim has been severely censured for this act of vandalism. In justice to him, however, it would appear that the ‘‘ it is nearly done” refers to his “ good supply,’’ for he is offering plants for exchange, and, in a later paper, he says that the Scheuchzeria was still plentiful in August of the same year. However, the deed is not one which merits condonement, any the less that its author in the same paper expresses the pious opinion that ‘“‘ It is very ungracious of any botanist to root up any rare plant.’” He gathered it in 1874 for the last time. As it happened, these depredations did not matter very much, for other causes later made it impossible for the plant to survive there. A large colony of black-headed gulls settled in Methven Bog, and caused a rank growth of vegetation, to the detriment of smaller plants. Then, about 1880, to accommodate the gulls, the myre was flooded which would drown the plant if it still existed. It is only on dry summers that the place can be reached, yet it has been searched since then, but without result, in 1888, by Dr. Buchanan White and Mr. Barclay, and again about 1898 by Mr. Barclay and Mr. Meldrum. There are specimens from this locality in the Herb- arium at the Royal Botanic Garden, Edinburgh, dated 1877, and this is probably about the latest date for the plant at this station. Until this year Scheuchzeria has been found at no other station in Britain, and the evidence shows that it is lost and presumably extinct at all these stations. In July of this year, however, I discovered the plant on Rannoch Moor, in the Perth-Argyll area, so that it is still entitled to a place on the British list. It was growing there in fair quantity in a very wet, peaty marsh associ- ated with Carex limosa and an intermingling of marsh and peat moor plants, a combination which appears to be characteristic of the habitat of Scheuchzeria, both in this country and in regions where it is more plentiful. 60 ~ ScaRTH—SCHEUCHZERIA PALUSTRIS.

DUNN, B.A. tie 2RGS, With Plate LXI. In the woods and damp alpine meadows of the eastern flanks of Tibet and adjacent ranges occur a number of species of a very marked section of the Primulas, having close heads or spikes of small blue or purple flowers, borne on long, slender scapes which arise from a rosette of entire or crenulate leaves. Their fragrance and the fine colour of their flowers have fre- quently brought them under the notice of horticultural collectors, and, as a result, several species are now in cultivation in Europe. Their flowering under cultivation has invariably been in May, though in their wild habitats, so far as is known, their flowers are always produced during the latter part of July and August. When Pax and Knuth published their monograph of Primu- laceae in 1905, three species only of this group had been distinguished—P. bellidifolia, King, P. cernua, Franch., and P. Viali, Franch.; one more was described in that work—P. Giraldiana, Pax; four have been published since—P. dejlexa, Duthie, P. Littonitana, Forrest, P. muscariotdes, Hemsl., and P. pendulifiora, Petitm. ; while two more, P. Watsoni, Dunn, and P. gracilenta, Dunn, are added in the present paper founded on material in the Herbarium of the Royal Botanic Garden, Kew. P. Watsoni, Dunn, is represented at Kew by a living plant, communicated by Professor Balfour from the Royal Botanic Garden, Edinburgh, and it was his inquiry concerning it which led to the investigation of the group resulting in the following notes. The ten species which are enumerated below, though having the appearance of being easily distinguishable, and being, in such cases as can be judged, quite distinct horticulturally, yet present some difficulty when it is attempted to arrange them in a systematic series. It may be that in some cases sexual forms, corresponding with the different relative positions of stigma and stamens well known to occur in this genus, have been [Notes, R.B.G., Edin., No. XXIII., December 191I.] 62 DUNN—PRIMULA BELLIDIFOLIA, KING, mistaken for nearly allied species. A careful study of this should be made when these species are better known in cultiva- tion, in order to throw light upon the subject. . KEY TO THE SPECIES. Calyx teeth acute 1. Giraldiana.

Primula eter tet Pax, in Engl. Pflanzenreich, Primul. (1905), fig. 27a. A blue-flowered species of northern Shensi; geographically an outlier of the group’ s range and morphologically distinct from the other species by reason of its acute calyx teeth. There is no specimen at Kew. 2. Primula deflexa, Duthie. Primula Viali, Pax, quoad fig. 27c., in Engl. Pflanzenreich, Primul. (1905), 93. 3. Primula muscarioides, Hemsl., in Bot. Mag., t. 8168. The flowers under cultivation are pale purplish-blue. The species is found in the portion of Yunnan lying north of the Yangtze Kiang. To Hemsley’s original locality may be added Tsekou, Soulié, No. 1347, and Monberg. -AND ITS ALLIES. 63 4. Primula bellidifolia, King. The plant, which has bluish-purple flowers and grows in Sikkim, seems never to have been cultivated. 5. Primula Watsoni, Dunn. Sp. nov. Plate lxi. Herba perennis.

Scapus strictus, 10-30 cm. altus, glaber, apice farinosus, capitulum globosum vel spicam ovatam gerens. Flores sessiles, 8-12 mm. longi, bracteis lanceolatis 4mm.longis. Calyx late campanulatus basi farinosus 2-3 mm. longus; dentes 5 paullo irregulares tubum aequantes, late ovati, margine ciliati. Corolla glabra atropurpurea ; tubus cylindricus, 7-10 mm. longus, 1°5 mm. latus ; limbus cupularis, 3-4 mm. latus; lobi 5, 2 mm. longi et lati, truncati vel retusi. Capsula ovalis, 4 mm. longa. Probably all from the elevated woodlands among the high mountains round Ta-tsien-lu in W. Szechuen, Pratt, 252 (part), Soulié, 152, Wilson, 4036. The species which has recently been introduced into cultiva- tion has its deep purple flowers relieved by the bright yellow powdery coating of its scapes and inflorescence. [The seeds were sent in 1908 to the Royal Botanic Garden, Edinburgh, by Mr. C. Watson, Solicitor, Annan, Dumfriesshire. They were collected by his son, Mr. Charles Marson Watson, after whom the species is named, at Ta-tsien-lu, at an_elevation of 10,000 ft. The plant flowered at Edinburgh in summer of the year I9II, as did also Primula deflexa, Duthie, raised from seed received from the same source and at the same time. ] 6. Primula pendulifiora, Petitm., in Le Monde des Plantes, x (xt Delavay, 3826. Not yet in cultivation, but in consequence of its large (for the group) deep purple flowers, probably one of the finest of the capitate Primulas. 7. Primula Littoniana, Forrest. Bot. Mag., t. 8341. Forrest, 2655. Few new discoveries have received such immediate or such well-merited recognition. It is not five years since Forrest first saw it growing in moist alpine meadows in N.-W. Yunnan, and he not only secured excellent photographs of it upon the spot, but brought home dried specimens and seeds, \4 64 DUuNN—PRIMULA BELLIDIFOLIA, KING, AND ITs ALLIES. through which it is already well represented in many herbaria and gardens. 8.

The total number of species of Pedicularis in this collection made by Mr. Forrest in the western parts of Yunnan is 43; 0 these 6 are new—P. Margaritae, P. Balfouriana, P. Smithiana, P. Forrestiana, P. taliensis and P. Stadlmanniana ; the proportion of new species is 13, 9 per cent. of the whole. Further, 2 species (P. siphonantha, Don, and P. szechuanica, Maxim.) had not been recorded before from these regions so far as I am aware. In comparing the results of Forrest’s collections with those obtained before by Pére Delavay, we note that the latter has collected at Tali and contiguous districts 48 species of Pedi- cularis. Out of these, P. brevifolia, Don, P. integrifolia, Hook. f., P. lachnoglossa, Hook. f., P. longicaulis, Franch., P. macilenta, Franch., P. melampyrifolia, Franch., P. oligantha, Franch., tag rigida, Franch., P. rhodotricha, Franch., P. sigmoidea, Franch., P. strobilacea, Franch., P. villosula, Franch., are not represented in the collection of Mr. Forrest described above. The total number of species indigenous in that part of Yunnan is, or seems to be at present, 56. Out of these, 32 species have not been recorded so far anywhere else. PLANTAE CHINENSES FORRESTIANAE.

This genus, which seems to be nearest allied to Pholidota, Lindl., is very remarkable in the group of the Coelogyninae by the presence of a spur at the base of the labellum, a character which as yet has never been observed in any genus of this affinity. From Pholidota it is besides distinguished by the slender column. It gives me great satisfaction to be able to dedicate this genus to Mr. A. K. Bulley, who by sending out such an able collector as Mr. G. Forrest has greatly advanced our knowledge of the Flora of the more unknown parts of China. v Bulleyia yunnanensis, Schltr. Sp.noy.

This remarkable plant at first sight has the appearance of a large flowered species of Pholidota, as the spur of the labellum is hidden between the sepals. The presence of a genus with a spurred labellum is most unexpected in the group Coelogyninae, as hitherto, with the exception of small concavities at the base of the labellum, nothing like it is known in this affinity.

Veitch of Chelsea, under 15a W. This plant flowered in a cool plant-house for the first time in October Igo9, and again in 1910. From the plant which flowered in IgII a specimen has been dried as the type in the Edinburgh Herbarium. A figure of the plant will appear in a subsequent number of the ‘“ Notes.” “ Didymocarpus V eitchiana is quite a striking plant, the leaves having the green sheen of a begonia, and the dark claret-purple flower-buds show up conspicuously against them. It is compara- tively easy to grow, requiring a goodloam mixed with plenty of leaf soil. The herbaceous stems taken from the top of the woody rootstock are easily rooted, as are the leaves if placed in a warm, moist case.’ —L. B. Stewart. SMITH—DIDYMOCARPUS. LIST OF PLATES.

S1ncE the publication of the ericaceous genus Craibiodendron in the Records of the Botanical Survey of India, vol. iv. p. 276, I have had the opportunity of examining additional Indo-Chinese material, chiefly in the Herbaria of Kew and Edinburgh. I found that Mr. S. T. Dunn, dealing with Chinese material in the Kew Herbarium collected by Dr. A. Henry, had marked certain sheets as representing a new genus of Evicaceae, an interesting confirmation of the view taken by Mr. Craib and myself in our examination of the Burmese and Siamese specimens. A survey of this new material and comparison with a wider range of related genera than was before possible have led me to consider the new genus as more closely related to Leucothoé than to Pieris or Lyonia, This is supported by the somewhat imbricate, almost free sepals, the muticous anthers and the winged seeds. I find the character of the large, unilaterally winged seeds to hold good in the three species of which fruits are available. Craibiodendron shanicum extends into Yunnan, W. China. In this province are two other closely allied species, C. Henryt and C. yvunnanense; a fourth species, the imperfectly known C. Forrestii, was obtained by Forrest in the upper Salwin valley. What is probably a fifth species is found in Assam, C. Mannit, also incompletely known. C. Henryi in its typical state is distinct enough from C. shanicum: in Burma, the latter, recorded from several localities, shows little variation, but in Yunnan there are forms (vid. Henry 9505B, in Herb. Kew et Herb. Edin.) which suggest a transition. The Khasian species and the shrub collected by Forrest in the Salwin valley are very inadequately represented, but a short description has been given here for the sake of completeness. {Notes from R.B.G., Edin., No. XXIV., January 1912. ] E yur 158 SMITH—CRAIBIODENDRON.

LTD. THE ROYAL BOTANIC GARDEN, EDINBURGH. THE. Royal Botanic Garden, Edinburgh, is one of three Gardens maintained by the State in the United Kingdom, the others being the Royal Gardens at Kew in England, and the Glasnevin Garden at Dublin in Ireland. It occupies an unequally-sided quadrilateral area of 57°648 acres (bounded upon all sides by public roads and dwelling-houses) on the North side of Edinburgh—about a mile from the shore of the Firth of Forth. Its highest point, at Inverleith House —the official residence of the Regius Keeper of the Garden——towards the North-west, is 109 feet above sea-level, and thence the ground falls away on all sides. The lowest point—a depression 48 feet above sea-level, with an east and west trend through the middle of the Garden— is the site of an old bog, and the ground rises again to the south of the depression. The surface soil is generally alluvial sand resting on clay at considerable depth. In the lower part of the area the clay comes to the surface. There are two entrances to the grounds—one upon the east side from Inverleith Row into the Garden, the other upon the west side from Arboretum Road into the Arboretum. The entrance to the Library is from Inverleith Row. The Garden is open daily from 9 a.m. on Week-days and from II a.m. on Sundays until sunset. The Plant-Houses are open from I p.m. until 5.30 p.m., or until sunset if this be earlier. The Museum is open on Week-days from 9 a.m. until 5 p.m, and on Sundays from I p.m. until sunset. The Herbarium is open on Week-days from 9 a.m. until I p.m., and from 2 p.m. until 5 p.m., excepting on Saturday, when it is open until I p.m. The Library is open on Week-days from 9 a.m. until 10 p.m. (Notes, R.B.G., Edin., No. XXV, June 1912.] Staff of the Royal Botanic Garden, Edinburgh, at June, 1912.

In the year 1670 a small portion of ground, known as St. Ann’s Yards, lying to the south of Holyrood House, and usually let to market gardeners by the Hereditary Keeper of Holyrood House, was occupied by two eminent Edinburgh physicians, Andrew Balfour and Robert Sibbald, for the making of a Physic Garden, and James Sutherland was appointed to the “Care of the Garden.” This was the foundation of the Royal Botanic Garden of Edinburgh, which is therefore, after that of Oxford (founded in 1632), the oldest in Great Britain. The Garden was stocked with plants from the private Garden of Dr. Andrew Balfour, in which for some years he had been accumulating medicinal plants, and also in great measure from that at Livingston in West Lothian, the laird of which, Patrick Murray, was much interested in the growing of useful plants, Shortly thereafter, but at what precise date has not yet been ascertained, Sutherland became custodian of the Royal Garden, which lay on the north side of the Palace, and it became a Physic Garden for instruction, whilst the original plot in St. Ann’s Yards was, apparently, given up. In 1676 the same physicians acquired from the Town Council of Edinburgh a lease of the Garden of Trinity Hospital and adjacent ground for the purpose of a Physic Garden in addition to the Garden already existing at Holyrood, and they appointed the same James Sutherland (1639 ?-1719) to be “ Intendant” of this Garden. The site of this Garden, which for convenience of reference may be called the Town’s Botanic Garden, was the ground lying between the base of that portion of the Calton Hill upon which the prison is built and the North Bridge, and it is now occupied by a portion of the Waverley Station of the North British Railway. The name Physic Garden attached to a street in the vicinity is a reminiscence of the existence of the Garden at this spot. About 1702 another Botanic Garden was established in Edinburgh in the ground immediately adjacent to the College vi Historic NOTICE. Buildings, apparently on the site of the present South College Street. This was the College Garden, and of it James Sutherland became also custodian. Thus in the early years of the eighteenth century there were in Edinburgh three distinct Botanic or Physic Gardens—one at Holyrood, the Royal Garden; one around Trinity Hospital, the Town’s Garden; and one beside the College, the College Garden—all under the care of James Sutherland. Sutherland from the first made use of the Royal Garden for giving “instruction in Botany to the Lieges,” and received a royal warrant appointing him Botanist to the King in Scotland, and empowering him to “set up a Profession of Botany” in this Garden. When the Town’s Garden was created the Town Council appointed him to lecture on Botany as Professor in the Town’s College, now the University of Edinburgh. In 1683 he published his “Hortus Medicus Edinburgensis, or a Catalogue of the Plants in the Physical Garden at Edinburgh,” from which and from other published notices we learn that between two and three thousand plants were in cultivation. There are no data available from which to determine how these plants were distri- buted between the several Gardens at the date of publication of Sutherland’s catalogue. In 1706 Sutherland resigned the care of the Town’s Garden and the College Garden as well as his Professorship in the University, but, remaining King’s Botanist, he retained the care of the Royal Garden at Holyrood. Charles Preston (1660-1711) was appointed his successor by the Town Council, and there were thus established rival Gardens and rival Professors of Botany in Edinburgh. Charles Preston was succeeded in 1712 in his offices by his brother George Preston (1659-1749). Neither of the Prestons had ever the care of the Royal Garden. Sutherland’s appointment as King’s Botanist, Keeper of the Royal Garden, and Regius Professor of Botany was held during the pleasure of the Sovereign, and on the death of Queen Anne in 1714 he was not continued in office by George I. In 1715 William Arthur (1680-1716) received a com- mission as successor to Sutherland, but as he was implicated in an unsuccessful Jacobite plot to seize the Castle, he did not hold the office long. He was succeeded in 1716 by Charles Alston (1685-1760). ‘In 1724 the College Garden, having fallen into disorder, was HISTORIC NOTICE. vii turned to other uses; and in 1729, George Preston having retired, the Town Council appointed, as his successor in the charge of the Town’s Garden and as Professor of Botany in the University, Charles Alston, who as King’s Botanist had already the charge of the Royal Garden and was Regius Professor of Botany, Through him, after separation for a quarter of a century, the Royal Garden and the Town’s Garden were again combined under one Keeper, and the Regius Professorship of Botany and the University Professorship were similarly united. They have so continued to the present time. In 1763, the Royal Garden and the Town’s Garden proving too small and otherwise unsatisfactory, John Hope (1725-1786), who had succeeded Alston in his offices in 1761, proposed a transference of the two to a more congenial site in which they could be combined. At first it was intended to secure ground to the south of George Watson’s Hospital—the area upon which much of the present Royal Infirmary is built—but this not being possible, five acres of ground to the north side of Leith Walk, below the site now occupied by Haddington Place, were chosen. As Hope proposed to transfer the collections in the Royal Garden to the new Garden he was able to secure the support of the Treasury to his scheme, and the selected ground was leased in name of the Barons of Exchequer. At the same time the Town Council agreed to contribute £25 annually to the support of the Garden, this sum being the amount of rent expected from the letting of the old Town's Garden.. The plants from both Gardens were transferred to the ground at Leith Walk, and from this date there has been only one Botanic Garden in Edinburgh. The site thus secured for the Garden proved, however, only a temporary one. Daniel Rutherford (1749-1819), who in 1786 succeeded Hope in his offices, cast about him for a spot in which more ground would be available for the extension of the Garden; and eventually in 1815 nine and a half acres of the land lying to the east of Holyrood Palace, and forming the ground of | Belleville or Clockmill, was fixed upon as a site. This selection gave rise to controversy which was prolonged, and Rutherford died before any arrangements for the transference of the Garden had been made. Robert Graham (1786-1845), his successor, appointed in 1820, preferred the more open site of the Inverleith property viii Historic NOTICE. which the Garden now occupies, and fourteen acres of the Field or Park of Inverleith, known as Broompark and Quacaplesink, were purchased by the Barons of Exchequer from Mr. James Rocheid, its owner, in 1820, the lease of the Leith Walk Ground being sold. By 1823 all the plants had been transferred to the new Garden. In 1858, during the Keepership of John Hutton Balfour (1808-1884), who succeeded Graham in 1845, a further addition, by purchase from the proprietor of Inverleith, of a narrow belt of two and a half acres was made to the Garden on the west side; and in 1865 the Caledonian Horticultural Society having resigned to the Crown its lease of the ten acres of adjoining ground which it had occupied since 1824 as an experimental Garden, this ground was also made part of the Botanic Garden. Finally the present area of the Garden was completed in 1876, when the Town Council purchased from the Fettes Trustees twenty-seven and three-quarter acres of Inverleith property on the west side of the Garden and transferred it to the Crown for the purpose of making an Arboretum in connection with the Garden; the Crown at the same time purchased Inverleith House and two and a half acres of additional ground. In 1879, Alexander Dickson (1836-1887) became Queen’s Botanist, Regius Keeper and Professor, and held these appoint- ments until his death in 1887. During his term of office the Arboretum was opened to the public. Surrounded as it now is on all sides by public roads, no further extension of the Garden upon its present site can be made, Regius Keepers (R.K.) from the Foundation of the Garden.

The method through which the Garden was built up by successive additions resulted in an absence of combination between its several parts, in great measure a consequence of want of adequate funds to make the necessary alterations in the grounds. During the past twenty-three years, in which the Garden has been wholly under the administration of the Com- missioners of H.M. Works, the bringing about of this combination has been in progress. The work is not yet completed, and the Plan of the Garden which is attached to this sketch shows the area of the Garden as it is laid out at this date—June, rorz2. Future editions will show further changes as the work of re- construction proceeds. From its foundation the Botanic Garden has been devoted to the teaching of Botany, and its usefulness in this respect has determined the laying out of its area. Herbaceous Garden.—A considerable space is occupied by a collection of herbaceous plants arranged for study in natural orders. Rock Garden.—There is an extensive rockwork upon which alpine and rarer herbaceous plants are cultivated. Arboretum.—tThe whole of the western area of the Garden is in process of arrangement as an Arboretum of trees and shrubs, and the positions of some of the chief genera are indicated on the plan. The Conifere are now placed in the ground adjacent to the Rock Garden. - Herbaceous Border.—Along the North Boundary of the Arboretum a mixed Herbaceous Border has been planted. The Plant-Houses are still in process of reconstruction. So far as they have been rearranged at the present time they consist of a long range to the north of the herbaceous collection, composed of a Central Green-house (C), from the sides of which two Corridors run east and west. In the Entrance Porch (D) to the Central Green-house is a collection of Insectivorous Plants. From the Eastern Corridor two houses project to the south—one xii FEATURES OF THE GARDEN. (A) occupied by Plants of Dry Regions, the other (B) containing Economic Plants of both Tropical and Temperate Regions. To the south side of the Western Corridor are attached two houses —one (E) for Orchids and one (F) for Plants of Tropical and Warm Regions. The western end of the Corridor opens into a domed house (G) for Ferns of Tropical Regions which are planted out, and attached to it are two houses running southwards, one of which (H) is occupied by Tropical Plants—Pitcher Plants are also cultivated in this house—and the other (I) is used as a Heath House. From the northern wing of this domed house opens a house (J) devoted to monocotylous Plants of Tropical and Warm Regions, specially Aroids, Scitaminex, Liliacez, and Amaryllid- acez. Out of this opens the house (K) for Bromeliads; and in another house (L) opening from this is a rockery for plants that do not thrive well in the open. Behind the western end of the Front Range there is a Temperate Hotise (M) for Palms, Tree- Ferns, and Coniferze, and a Palm-House (N). Adjoining Inverleith Row is a group of buildings including the Museum (0), the Laboratories (P), the Lecture Hall (Q), and the Library (R). The Museum contains a series of exhibits illustrating the form and life-history of plants, and these are arranged so as to facilitate their use in teaching. The Library contains over sixteen thousand volumes. The leading botanical and horticultural periodicals are taken and may be consulted like the other books by the public. Books are not lent from the Library. Herbarium.—In the southern portion of the Garden is the Herbarium (S). It contains a fair representation of the Floras of the world. A Ladies’ Cloak-Room is at (T). A Gentlemen’s Lavatory will be found at (V). From the higher ground of the Arboretum—at the point marked (X) on the plan—a fine panoramic view of the City of Edinburgh, flanked on the east by Arthur's Seat, and on the west by the Pentland Hills, is obtained. Teaching in the Garden. Special instruction in the sciences underlying the practice of Horticulture and Forestry is provided for the Staff of the Garden. The course of instruction is spread over three years, and consists of lectures upon, and practical instruction in, the sciences taught. A Reading-room and Library is also provided for members of the Staff going through the course. Young Gardeners or Foresters desiring admission to the Staff and the course of instruction should make application to the Regius Keeper. The Regius Keeper from time to time gives lectures which are open to the Public. The Laboratories are open to anyone desirous of undertaking Botanical Research. For more than a century and a half the offices of Regius Keeper of the Botanic Garden and Professor of Botany in the University of Edinburgh have been held by the same person, and it has become the custom that the students of the University come to the Garden for instruction in Botany. Specimens for private study are supplied, as far as the resources of the Garden will permit, to visitors and students who make written application to the Regius Keeper. Application forms may be obtained at the office of the Garden. Enumeration of Visitors to the Royal Botanic Garden, Edinburgh, during the Years 1889-1911. ON the ist of April 1889, the control of the Royal Botanic Garden, Edinburgh, was vested in the Commissioners of His Majesty’s Works, and the Garden became subject to the “ Act for the Regulation. of the Royal Parks and Gardens, 1872.” From the date specified the Garden has been opened to the public on Sundays, and also for an extended period on Week- days.

A. longistyla differs from A. tonandra in its long-pedunculated flowers, the longer and narrower leaves, and the rounded, not DreL_s—ComposIrAk. 183 emarginate, petals. The length of the style is a variable character of the species. It may be a case of heterostylic condition. In fact, this assumption is strengthened by d’Apreval’s plate (Plant. Delavay., Plate xxiv.), which figures two forms of ovary in d and e: a long-styled and a short-styled one. Therefore, Franchet’s section Macrogyne is invalid, his A. Jdongistyla being, indeed, closely related to his A. napuligera. Our A. tonandra is an intermediate form between those two species. COMPOSITAE. \o*°" Pluchea Bulleyana, J. F. Jeffrey. Sp. nov.

Ind. iil, pp. 255-256), by its stouter habit much branched from the base, with the outer phyllaries spreading and refiexed, leafy stems and villous involucre. From E. multi- radiatus, Benth., the more villous involucre readily distinguishes it. In Forrest’s plant the phyllaries lengthen in fruit and are sharply acuminate. The spreading villous hairs of the stem are very characteristic. De Candolle’s description of Heterochaeta erigeroides (DC. Prod. v, 282) strongly suggests the present plant, but the outer pappus in FE. patentisquama can hardly be said to be developed, and De Candolle’s is described as having the stems leafy only at the base and only 3 to 4 inches high. I have taken up Mr. Clarke’s MS. name in the Kew Herbarium on the sheet of his No. 30713 from Tilail, 12,000 ft., Kashmir. Sir J. D. Hooker has noted on this sheet that Clarke’ s plant was “not seen when F.B.I. was done.” Jaeschke 256, Lahul, Thibet, has also been identified by Sir J. D. Hooker in Herb. Kew as var. patentisquama.

Indeed there is a specimen from China in the Kew Herbarium (Henry 64) closely approaching the present plant which has been named provisionally by Prof. D. Oliver A. vulgaris, var.?

I do not know if this interesting form will prove specifically different from O. Acetosella. By describing it, I want to draw the attention of the collectors to it. Forrest’s specimen is certainly ¥ y en. > 224 PLANTAE CHINENSES FORRESTIANAE, very different from the typical O. Acetosella, e.g. Forrest, No. 2144, by its much smaller size in all parts, the relatively longer peduncle (much exceeding the leaves), the very few scales at the base of the flowering shoot, their bulbous development and curious chalky-white colour, the very narrow bifid petals, and the late time of flowering.

Although the classification of Veratrum is very unsatisfactory, I think Forrest’s plants may be considered a new species, recognised by its very narrow leaves and bracts. It is allied to V. dahuricum, Turcz. There are several other forms of the genus in Western China, SCITAMINEAE. ‘\ Hedychium Forrestii, Diels. Sp. nov. Caulis 0°6—1'2 m. altus, glaber.

A similar plant seems to be Hancock, No. 387, from Red River, Southern Yunnan, in Herb. Kew ; I have not dissected its flower. This species is different from H. coronarium by its narrower spreading bracts, the narrower segments of the corolla and broader staminodes. I could not find out some of the details of the flower without destroying the specimen. The description must be completed from living specimens. Index to Species.
