CXLVIII.—CY PERACE A, PERENNIAL, rarely annual herbs, with the habit of grasses; roots fibrous; stem terete or 3-angled, rarely branched; 1. grass-like (rarely 0), 3-ranked, mostly crowded at the base of. the stem, upper fewer, with tubular sheaths, which are more or less closed, or the lower split to the base, ligule 0, or a short prolongation of the mouth of the sheath opposite the blade; infl. of solitary, fascicled, panicled, or spicate spikelets, composed of small imbricating distichous, or spirally imbri- cating scales (glumes); fl. minute, uni- or bisexual, in the axils of the glumes; perianth o, or of 6 or more hypog ynous bristles or scales (ovary enclosed in a utricle in Carex) ; stam. 1-3, fil. flattened, anth. basifixed, linear; ov. i-celled, style short or long, stigmas 2-3, ovule 1, basal, erect, anatropous; fr. a compressed or trigonous nut; seed erect, free, embryo minute, within the base of the floury endosperm. In using the following key and the generic characters given of the Ceylon Cyferacee, it is absolutely necessary, for their proper understand- ing, to bear in mind that the so-called spikelets of the tribe Cyfeve@ are not homologous with those of the other tribes. In the Cyperee@, each flowering glume of the spikelet bears one bisexual fl., and any scales or bristles placed around or below the stamens are considered to be organs of that fl. (disk or perianth). In the other tribes, what appear to be the glumes of a spikelet are considered to be bracts of a spike, each of which bracts bears in its axil a spikelet (homologous with that of Cyferee), reduced to a sessile ovary, accompanied or surrounded with scale-like glumes, which are not arranged upon a rhachilla, but are arranged around the ovary in a certain order, which can only be ascertained by very care- fulexamination. In Ayfolytree, two of the scales are always external to the others, placed right and left of the ov., are monandrous, concave, ‘strongly laterally compressed and keeled, the keel ciliate, the other scales, one or more of which are monandrous, are flat and variously placed. In Sclertee, where also what appear to be the glumes of a spikelet are considered to be the bracts of a spike, the true spikelet also consisting of scales, like glumes, and the male glumes are‘usually on a separate spike. There is no trace in Sclerze@ of the two right and left glumes of //yfolytree. Lastly, in Caricee the true spikelet is represented in the male spike by stamens only, and in the fem. by an ov. enclosed in a utricle, which latter i is the homologue of the two right and left scales of | Hy polytree. From the above it may be concluded that it is very difficult to apply to the infl. of Cy~eracee a nomenciature at once scientific, practical, and _ intelligible to the student without much circumlocution; I have there- fore followed the simplest course of using, throughout the Order, the term spikelet for both spikes and spikelets, and of scales for the glumes- of the true spikelets of Hypolytree and Scleriee.—J.

B. Ind. A satisfactory classification of the species of CyZerus in linear sequence is, Owing to their cross affinities, and their variability in habit and in the development of the infl., perhaps unattainable. For this work (in which dichotomy is the rule adopted by Dr. Trimen for the construction of the keys), I have chosen for the principal subclivisions of the genus characters which, though in great measure artificial, will, I think, be serviceable to the student in his endeavour to identify the Ceylon species. This I have followed with an account of the arrangement adopted by Mr. Clarke in the Flora of British India, which is partly natural and partly artificial ;—wholly artificial in retaining /wacel/us as a genus, and natural in adopting Pycreus. With regard to the latter genus, though not adopted by Dr. Trimen in the list of Cyperacee, which he drew up for description in this work, it is well distinguished from Cyfervus by the laterally com- pressed nut, and is, as Mr. Clarke informs me, only distinguishable from Kyllinga by habit and the inarticulate rhachilla of the spikelets.

It is so closely allied to cyperinus, that it is difficult to distinguish it by description. In its ordinary state it is a less robust plant, with more cylindric spikes of widely spreading or reflexed often almost golden-yellow spikelets. 7. ME. tenuifolius, Schrad. in Mart. Fl.

Ceylon (Koenig in Herb. Mus. Brit.). Also collected at Colombo, first by Ferguson in 1867, but, doubtless, occurs elsewhere. FI. April (?). Southern India (?). Clarke considers this as identical with a very widely distributed Indian, Malayan, and Australian plant, which is Wallich’s 3516A and 3517 B,D,E. I, on the other hand, regard it as a distinct and local plant, first found in Ceylon by Kcenig, and of which there are, as Mr. Rendle informs me, specimens in the British Museum. It is certainly the /. @stivalis of Wight’s Catalogue, No. 1880, where Wallich’s 35164 and 3517 € are erroneously cited as conspecific. The latter, a widely dis- tributed Indian, Malayan, and Australian species, not hitherto found in Ceylon, is a taller, more slender plant, with looser umbels, smaller spikes, shorter cusps of the glumes, which have never a squarrose appearance, and a short tip of the nut.

The above generic and specific descriptions are almost wholly derived from Dr. Trimen’s notes, who says that the fl. heads are made the nests of small ants, and are full of water and soil, so that the scales and stamens soon become rotten and pulpy. The maggots of flies live in these and eat the anthers.

The following Key to the tribes and genera of Sinhalese grasses is rather a compromise adapted to the wants of a colonist than a strictly scientific co-ordination. In drawing it up I have adhered pretty closely to that given for the whole Order by Bentham (Gen. Plant.), as slightly modified in the Flora of British India. The few important changes (indicated where they occur) are chiefly due to the later revision of some of the tribes by Dr. Stapf, prepared for the Flora Capensis (ined.). I have not, however, adopted all the views of that able student of grasses, deeming that some of them want further consideration. It must be allowed, I think, that there is no more difficult problem in the classifica- tion of the genera of any large order of phanerogams than that which the grasses present. The primary divisions of Panicacee and Poace@ is a | very unsatisfactory one, though founded primarily on such apparently important characters as the relative position of the fertile flowers on their axis of growth (the rhachilla), and that of the spikelets being articulate or not at the base, whereupon depends in a great degree the dispersion of the seeds. Of the recognised tribes, some are more or less artificial, containing genera of doubtful affinity; nor, as it appears to me, would it be difficult to multiply the tribes indefinitely, by giving tribal value to anomalous genera. On the other hand, the genera themselves are, on the whole, well circumscribed. Though some are divisible into sections * The term ‘spike’ is loosely used in this Order, or is more or less conventional. In some genera with contracted infl., the pedicels are so short that the spikelets are sessile or subsessile, when the term is legitimate ; in others, where the spikelets are binate, a sessile and a pedicelled, the terms ‘spikes’ and ‘raceme’ are interchangeable. Graminec. 115 which may be regarded as genera, these as such do not disturb the classification by being referable to other tribes. As stated in the Preface to Part IV., no materials were left in MS. by Dr. Trimen for the elaboration of the grasses, my resources are hence limited as regards habitats, colours, and flowering seasons. For the former I am dependent on those given in Thwaites’s ‘Enumeratio’ in the Peradeniya Herbarium, where unfortunately many species have no habitat or date of collection assigned to them, and especially in the late Mr. Ferguson’s valuable essays on the grasses of Ceylon.* I am also indebted to Mr. H. H. W. Pearson for the loan of his carefully ticketed collection of grasses, made chiefly in the patanas of the island in 1898. For the flowering seasons of the grasses I am altogether deficient of resources. As with the Cyferacee, they would seem, from such dates as I find attached to some specimens, to be either greatly prolonged, or to occur twice in the year, dependent on the monsoons, the wet and dry climates, elevation above the sea, and exposures. A full account of the distribution and flowering seasons of the Ceylon grasses could not fail to be both instructive and interesting. The two charts issued with this Part of the Handbook, of the rainfall and forest regions of the island, indicate data as to climate and geographical areas, available for an essay on this subject. Series I. Panicaceze.—Spikelets usually articulate on their pedicels and deciduous from them when in fr., rarely persistent and deciduous with them, binate, a sessile fruiting and a pedicelled male or neuter, rarely solitary; glumes 3 or 4, rarely only 2, rhachilla of spikelets rarely produced between the bases of the glumes or beyond the upper glume; sessile spikelets 1-2-fld. (never more), upper fl. alone (if 2) fruiting — Herbs, Spznifex alone shrubby of Ceylon genera. Lxceptions.—Spikelets persistent or tardily deciduous, or glumes I and II separately deciduous in /sachne, Chama@raphis, Pennisetum, Stenotaphrum, Thuarea, Arundinella, and Zoysia. Spikelets inarticulate at the base and deciduous with the internodes of a fragile rhachis in many Azndrofogonee. Both fis. of the spikelet of some species of Isachne ripen fruit. Spikelets articulate on their pedicels and deciduous occur in Poaceae, in Garnotia, Polypogon, Sporobolus, and Lophatherum. Lower fl. in the spikelet male and upper fertile, occur in Phragmites, &c. A. Rhachis or branches of infl. inarticulate; pseudo-articulate in Stenotaphrum, articulate in Zrachys. Some genera of Tribe Axdro- pogonee have inarticulate branches, racemes, or spikes. * “Notes on the Grasses and their Distribution in Ceylon, by W. Ferguson, F.L.S., read before the Ceylon Branch of the Royal Asiatic Society (1880).’ I have seen no copy of this paper, only a préczs of its contents kindly made for me by Mr. Lewis of the Forest department. ‘Graminez or Grasses Indigenous to or Growing in Ceylon, with Notes especially on those used as Fodder Plants, by W. Ferguson, F.L.S.

Fer.uson (Gramin. 3) observes that there are five varieties of this plant cultivated in Ceylon, with different Sinhalese names. One variety, called Mat amu (amu=inebriating) gives a poisonous quality to the water in which the grain is boiled. Ainslie (in his Mat. Med. Hindost.) says of a variety called Serraku Warugu, T., that if not dressed in a peculiar manner it is said to produce vertigo and nausea _ In Dalzell and Gibson’s Flora of Bombay, it is stated that in the hill-lands of the Concan large numbers of natives may be seen affected with temporary insanity and spasms from eating the seeds of a variety there called Hurruk. 2.

The above description is from specimens in the Peradeniya Herbarium, which are very characteristic of the type form of the plants differing from P. Crus-gallz in the slender stem and panicle, hardly bearded at the nodes, short spikes, with few bristles on the rhachis and smaller spikelets with rather shorter glume III; but no doubt intermediates between these specimens and those of /. Crus-galli exist in Ceylon as elsewhere. Ferguson cites it as a synonym of P. Crus-gallz, with the observation, “Specimens of the large Crus-galli form spring up from seeds thrown -out from the bazaars, and become large tufted plants, quite different in appearance from the small wild P. colonum.’ He does not mention it as a cultivated plant, which it is in India, where Roxburgh observes that he never saw it wild. 7.

Brachiaria. A well-known fodder-grass in Ceylon, but there is no record of its introduction into the Island. According to Roxburgh seeds were received at the Calcutta Botanical Garden from Sumatra in 1804, through Dr. Charles Campbell. As it is a native of Tropical America, the Dutch, who then held ports in Sumatra, may have imported it from Surinam. According to Ferguson, it and P. maximum are the two most valuable fodder-grasses in Ceylon. Unlike the latter, P. mutécwim grows best in well-drained low or swampy ground. It is singular that neither Thwaites, Trimen, nor Ferguson give a Sinhalese or Tamil name for it, and that it is not alluded to in Watt’s Dictionary of the Economic Products of India. 12, P. ramosum, L727.

Cultivated in Ceylon. Tropical countries. In Fl. B. Ind. 1 have followed most authors in keeping P. mzléare and P. pszlopodium as different species, assuming that the latter was indigenous in India and Ceylon. Mr. Duthie, who knows the cultivated grasses of India better than any one, has in vain tried to distinguish them (see Fodd. Grasses, p. 10). As P. pstlopodium it has been con- sidered to be indigenous in the Himalaya, but this requires confirmation. Ferguson cites P. mzlzare, Lam., as a synonym of P. mzliaceum, and P. psilopodium as a different species; but, as I have stated under the former, I think he has confounded two plants under the name, He mentions P. pszlopodium as a cultivated plant, adding that the cultivated form of both it and P. mz/za7e often spring up in the débris collected from the Colombo bazaars. Unfortunately he does not say how these grains are distinguishable. Watt (Dict. Econ. Prod. Ind.) mentions P?. pstlopodium as a species nearly allied to, or possibly a variety of, P. miltare, wild in the Himilaya, but also cultivated. The grain of P. miliare he describes as of inferior quality, and mostly consumed by the poorer classes. 29. P. czesium, Vees in Hook. Kew Journ. ii. 97 (1850). : P. reticulatum, Thw. ex Trim. Cat.

The well-known Guinea Grass was introduced from W. Trop. Africa. into Jamaica about 1774, by Mr. John Ellis, as food for some birds which he had imported. The birds died, and the seed, being thrown away as. useless, yielded a magnificent grass greedily eaten by cattle and horses. It was introduced into India in 1802 by Sir John Sinclair, and must have- been rapidly disseminated, for I find a specimen in Rottler’s Herbarium (named P. meneri, miliacca, var. (?) P.nodosum, nob.) received from Heyne, with the date, June 3, 1808. There is no record of its introduction into- Ceylon, but it is included in Moon’s Catalogue, published in 1824. Ferguson says of it that it grows in almost every soil and situation, and forms with P. wzuticum the two most valuable fodder-plants grown im Ceylon.

B. Ind. Dr. Stapf, who has made a careful study of the morphology of the spikelets of Ozyza, informs me that it consists theoretically or normally of 5 glumes, of which the two lowest are very minute, are confluent with the tip of the pedicel, and rarely discernible. The spikelet is hence only apparently articulate with the pedicel, the real articulation being above these two suppressed glumes. The two following glumes, also empty, are always minute, and one, or rarely both, are sometimes suppressed. The palea is very anomalous, being 3-veined and as coriaceous as the uppermost glume. Rarely a sixth glume is produced ; it is like the fifth, but narrower and empty; its palea is 2-keeled, as in most grasses. Dr. Stapf refers (in Flora Capens.) the Tribe Orxyzee to the Group Poacee, and places it near Pappophoree and Phalaridee.

It is extensively cultivated for its grain in Ceylon (as in all parts of India), up to 2500 ft., and is known as Marua in Bengal, Kaivarii or Kelvaragu in Tamil, and ‘ Raggi’ in Madras. Ferguson describes it as the most prolific of cultivated grasses. One variety, Z. stricta, Roxb., giving the increase of 120-fold; another 500- fold; whilst on two tufts, the produce of one seed, 56 stems grew; no less than 8100-fold of grain was carefully calculated to have been the produce of this plant.

Thwaites says of this, ‘possibly introduced.’ I suspect it is certainly so, but Trimen does not mark it as such in his Catalogue. Ferguson describes it as so very plentiful in various parts of Dambulla, and especially on the banks of streams not near cultivation, that, though it looks very like a native plant, it may after all be an escape from packets of English seeds.

The true position of I is evidenced by its margins overlapping the inflexed margins of II, and by its position, which faces the back of glume III. A study of the development of these two glumes would be interesting. Ovopetium (p. 271) shows the same deceptive insertions of glumes I and II. &. repens, 4&7. Prod. 207 (1810). Trim. Cat. Ceyl.

IT is assumed that those for whose aid in identifying the flowering plants of Ceylon the following Key is intended are so far instructed in the elements of botany as to be familiar with the principles of classification, with the characters of the classes Dicotyledons, Monocotyledons, and Gymnosperms, with the principal organs of flowering plants, and with the technical terms ordinarily used in describing ehem.* These acquirements would not, however, suffice to enable any one ignorant of Indian botany to make much use of this Hand-book, from the absence in it of subdivisions of the dicotyledons and monocotyledons, and from the fact that many of the genera present some characters foreign to the orders in which they are placed, but to which they, not- withstanding, belong by right of affinity. Added to this is the fact that the Ceylon Flora is, for its extent, a fragmentary one, certain orders represented in India by many genera, and certain genera by many species in India, being represented in Ceylon by single or very few genera and species, and these often being aberrant in one or more characters.. In evidence of the above I find that, out of the total of 149 orders, 49 are represented by single genera, and 23 by only two genera; and that, of the remaining 77 orders, 65 include one or more genera with aberrant species. One instance of the latter may suffice; it is the order Ranunculacee, which is normally polypetalous. It is represented in Ceylon by five * Those who have not these acquirements are recommended to pro- cure and study ‘Oliver’s First Book of Indian Botany,’ with numerous illustrations. (Macmillan & Co.) PART V. We 320 Key to the Orders, Genera, Se. genera, of which three are apetalous. These five genera together contain seven species, of which three only have petals. This, for the purpose of the Key, necessitates Ranunculacee finding a place both in the polypetalous series of Thalamifloral and the apetalous of Monochlamyds. So it is with various others of the Ceylon orders, genera, and species; owing to their aberrant characters their natural affinities are masked, and, except by an artificial key, it is difficult—in some cases even impossible—for one ignorant of Indian botany to identify them, and to find their places in the natural system which is followed in the body of the Hand- book.

APPENDIX TI, ON THE FORESTS AND WASTE LANDS OF CEYLON. With a Map showing the Forest areas.* By A. F. Broun, Esq., Conservator of Forests. THE area of uncultivated lands in Ceylon exceeds 20,000 of the 25,365 square miles of country contained within the Colony. The proportion of good forest in these 20,o00 square miles is unfor- tunately small, the largest portion being taken up by scrub and by grass-covered stretches of country called jatanas, which find their greatest development in the hills of the Province of Uva. The scrub is partly natural, especially so on the sea-coast and in the arid subzone, and partly the result of a destructive method of cultivation known as chena, and which consists in clearing and burning jungle and in raising crops for two or three years on the area cleared. Now that a careful control is exercised over this cultivation, nothing but small forest is felled; but not many years ago valuable forests were ruthlessly felled, and their: ashes were utilised as manure for the crops which were raised. Where such a system of cultivation has been in force, it takes years for the forest to take again a useful character. Usually a thorny scrub grows up; or, as is the case in the Eastern Province, a dense growth of Iluk grass (Jmperata arundinacea) springs up; or again, as in the moist districts, the ground gets covered with Zazfana, or, worse, because they are not soil-improvers, by Aedyotts, Ochlandra stridula, or Gleichenia linearis. The patanas were probably at one time covered with trees, such as will be described later on for the Park country, but fires and grazing have destroyed the majority of these, except in sheltered places such as gullies or ravines. The trees which are to be found on the patanas are, at higher elevations, Rhododendron arboreum, and, from 4000 feet downwards, Careya arborea, known in Ceylon as ‘Patana Oak,’ Phyllanthus Emblica, Terminalia Beterica, T. Chebula, and Prerocarpus Marsupium. These are, with few exceptions, the only trees which can stand the heavy grass fires; but in the gullies, * My cordial thanks are due to F. H. Grinlinton, Esq., Surveyor- General of Ceylon, for permission to reproduce this Map and that of the Forest Areas; and to P. D. Warren, Esq., Assistant Surveyor-General, for his kindness in supervising their reproduction.—J. D. HOOKER.} 356 The Forests and Waste Lands of Ceylon. where they are more sheltered, other species, which are less robust and which are the same as those found in forests at the same eleva- tion, are able to live and to reproduce themselves. In the backward state of the survey of the island it is not yet possible to state the area of the real forests, but they cannot much exceed 5000 square miles, although a larger area is, for the present, set aside for reservation, which includes stretches of scrub and patana englobed within the forests. The most important belt of forest stretches from the Northern Province, mostly between the centre line of the island and the east coast down to the Hambantota District, but important blocks are also found scattered over the rest of the island, chiefly in the Puttalam District of the North-western Province and in the upper hills, but also in the Kurunegala District of the North-western Province, in the Western, Southern, and Sabaragamuwa Provinces, where are still to be found, in isolated blocks, the remains of what was at one time the extensive Sinha Raja Forest. The vegetation of the forests varies especially according to rain- fall and elevation, and the forests can be classified according to the following zones and subzones :— Dry zones. + zone. Rainfall 35 to 50 inches. sa es te a9 Dry zone proper. Rainfall 50 to 70 inches. Intermediate zone. Rainfall 70 to 80 inches, a ee pore h U Low country zone from sea-level to 4000 feet. CIMINO) MOCISS ( Mountain zone above 4000 feet. and more. The Dry Zone.— this includes about three-fifths of the island, viz., the whole of the Northern, North Central, and Eastern Provinces, the Puttalam District and portion of the Kurunegala and Chilam Districts, the North-western Province, the northern part of the Central Province, about two-thirds of the Province of Uva, the Hambantota District of the Southern Province, and the Kolonna Korale of the Province of Sabaragamuwa. The Western Province is therefore the only one of which no portion enters in the dry zone. The Arid Zone occupies the North-western end of the island in the Puttalam, Mannar, and Jaffna Districts, and the South-eastern in the Hambantota District. The characteristic trees and shrubs of this subzone are Salvadora persica, Azima tetracantha, and Acacia eburnea near the coast, and Acacia planifrons on the island of Mannar.* The woody vegetation is usually shrubby and thorny, being represented by Carissa spinosum, Zizyphus Jujuba, Z. Gnoplia, Z. rugosa, Randia dumetorum, Flacourtia Ramontchi, &c. * Acacia Sundra is also found in the Puttalam and Hambantota Districts, Alb¢zzia amara in the Mannar District, and S¢trychnos potatorum not far from the sea. The Forests and Waste Lands of Ceylon. 357 Further from the coast the forest vegetation is composed of the same species as of the forests of the dry zone proper, but the trees are usually smaller and the undergrowth is composed mainly of Memecylon and of Stenosiphontum Rulyselianum. The Palmyra palm (Borassus flabelliformis) is found on sandy soil both in this sub- zone and in the dry zone proper. It is most abundant in the littoral districts, especially in the Jaffna Peninsula. The forests of the Dry Zone proper are the most important to the forester, not only because they are the most extensive, but also because they contain most of the valuable timber trees. The most important of these are Satinwood (Chloroxylon Swietenta), found on sandy soils, and attaining its best dimensions in the Puttalam and Batticaloa Districts; Ebony (Dzospyros Ebenum), which prefers rocky, undulating ground, and which, although found occasionally in the wet, low country, is most abundant in the Northern, North Central, and North-western Provinces, and in the Trincomalie and Matale Districts; Palu (MZimusops hexandra), which is found on more clayey soils from the north to the south of the island. It attains an enormous size, and grows best, if anywhere, in the Northern Province. It is one of the ironwoods of commerce. Trincomalie wood (Berrya Ammonzlla) is found in moist but well- drained places. It extends into part of the wet zone, but the trees are usually of small size. The finest trees are found in the eastern portion of the Province of Uva. Milla (Vitex altissima), one of the strongest of Ceylon timbers, extends also into the wet zone, where it is not uncommon; but, like the Bervrya, it is a much finer tree in the dry zone, especially in the Eastern Province. The same may be said of Ranai (A/seodaphne semecarpifolia), although it is not so common in the wet zone as Milla. The Ebenacez are (apart from Ebony) represented in this zone chiefly by D. ovalifolia, while D. crumenata, D. oocarpa, D. Embryopteris, and D. montana are also found abundant in certain localities; and Maba buxifolia is a small tree which is by no means uncommon even in the arid zone. Of the Guttiferee we have chiefly Garcinia spicata, Calophyllum Burmani, and, near streams or in groves, planted before the memory of man, Mesua ferrea. The Dipterocarps, which are so characteristic of the Low Country wet zone, are almost absent, being only repre- sented by Vatica obscura in moist soils in the Eastern Province, and by Hopea cordifolia along streams in Southern Uva and Saba- ragamuwa. Among trees which are characteristic of this zone the most common are Polyalthia longifolia, P. coffeoides, Crateeva Roxburghit, Pterospermum suberifolium, Sterculia fetida, Azadirachta indica, Walsura Piscidia, Pleurostylia Wightit, Sehleichera trijuga, -LNephelium Longana, Odina Wodier, Cassia Fistula, C. marginata, Bauhinia tomentosa, Acacia leucophlea, Acacia ferruginea, Gyrocarpus Jacquini, Eugenia Jambolana, Barringtonia acutangula, Adina cordt- folia, Canthium didymum, Bassia longifolia, Terminalia glabra (near streams and tanks), Strychnos Nux vomica, Cordia Rothit, Sivreo- 358 The Forests and Waste Lands of Ceylon. spermum chelonioides, Euphorbia antiguorum, Saptum insigne, Hemi- cyclia sepiaria, Mischodon zeylanicus, Holoptelea tntegrifolia, &c. The most common shrubs are Polyalthia Korint:, Allophyllus Cobbe, Ochna squarrosa, Cassia auriculata, Alangium Lamarckit, Webera corymbosa, Randia dumetorum, Gmelina astatica, Memecylon, Glycosmis pentaphylia, and Dimorphocalx glabellus. Creepers and climbers are not so well represented as in the moister zones, the most abundant being Hugonia Mystax, Ventilago maderaspatana, some species of Vitis, Derris scandens, D. stnuata, &c. ‘The most beautiful orchids found in this zone are, without doubt, Saccolabium guttatum, which is found in the Eastern Province, and Vanda Rox- burghit and V. spathulata, which are found chiefly not far from the sea. Vanda parviflora and Saccolabium Wighttanum are not un- common, while a pretty little white-ground orchid, Habenaria ptero- carpa, is found in rocky places. The ferns of this zone are not abundant, the Adiantum caudatum penetrating farther into the dry districts than any other, while Hemzonitis arifolia and Gymnopterts quercifolia are found in dark and moist places, while on rocks grow Cheilanthes mysorensis, C. axa, and the tiny Ophioglossum lusitanicum. In the Intermediate Zone trees of both the dry and the low- country moist zone are to be found, such as Berrya Ammonilla, Nephelium Longana, Mesua ferrea, Artocarpus integrifolia, Xylopia parvifiora, Albizzia stipulata, A. odoratissima, A. Lebbek, &c.; and there are a few species which, although they are found elsewhere, can be said to be characteristic ; these are /zdiccum decipiens, Chick- vassia tabularis, and Mela dubia. Terminalia Belerica attains an extraordinary size in this zone, in which are other gigantic trees, like Zetrameles nudiflora and Ailanthus malabarica.* Among the shrubs, Vétex Megundo is probably the most characteristic. Another characteristic feature of this zone is the great abundance of creepers, which cover the tallest trees and render forest operations extremely difficult. Some very handsome ferns grow in this zone, the most noticeable being Aspidium decurrens, A. subtriphyllum, A. cicutarium, and Adiantum lunulatum. The Park country of Uva can be included in this zone. It comprises the low lands on the eastern boundary of that province ; and it has a quite characteristic flora, very similar to that of the Sub-Himalayan forests. The trees which are found here are found only on the patanas and occasionally elsewhere, the most noteworthy being Axogeissus latifolia, Butea frondosa, Terminalia Chebula, T. Lelerica, Zizyphus xylopyra, Pterocarpus Marsupium, Miliusa indica, Sterculia colorata, Gmelina arborea, and Diospyros melanoxylon. The undergrowth is, as in the sub-Himalayan forests, mostly grass * Although Dipilerocarpus zeylanicus and Stemonoporus acuminatus extend into this zone, the only characteristic Dipterocarp known, so far, in this zone is the Balanocarpus zeylanicus, which has been found only in the Kurunegala District. a The Forests and Waste Lands of Ceylon. 359 (Imperata arundinacea), Near water-courses the flora is that of the ordinary dry zone type. The Wet Zone includes the Western Province, the Province of Sabaragamuwa excluding the Kolonna Korale, the Galle and Matara Districts of the Southern Province, the Hill Districts of the Central and Uva Provinces and about one-half of the Kurunegala and Chilaw Districts of the North-western Province, or, in a few words, the South-western and South Central portions of the island. It is the portion which receives the full force of the South-west monsoon, and includes the higher lands affected by the North-east monsoon, The rainfall usually ranges from 80 to 200 inches, but it exceeds even this in some places, and rumour has it that in Eratne, to the South- ‘west of Adam’s Peak, it actually does not fall far short of 400 inches. The Low-country Wet Zone is the country par excellence of the Dipterocarps. In the Chilaw and Kurunegala Districts, and in the Northern portion of the Colombo District, they are represented ‘only Ey Dipterocarpus zeylanicus, but further South and East they increase in number and species until, in many cases, they form almost the entire forest. No doubt, several new species will have to ibe added, and even since the first volume of Trimen’s Flora has been published fresh discoveries have been made, a case in point being the Stemonoporus (? Vatica) Lewist, which was found by Mr. F. Lewis of the Forest Department at about 1000’ altitude above Pelmadulla. The curious almost wingless fruit of Shorea lissophylla was also found near the Bentote river in the Western Province. The forests of this zone, where they have been saved, are to the eye the most magnificent of the whole island, the trees often reaching a height of too feet to the first branch. On this account the trees are often difficult to identify, and it is probable that many are still ainnamed, especially as it is not always possible to hit on new species at the time when they are in flower or fruit. The most beautiful of these forests is probably the forest of the Hinidun Pattu, in the Southern Province; in it the most important Dipterocarps are Dipterocarpus hispidus, which in the South almost replaces D. zey- lanicus, D. glandulosus, Shorea oblongifolia, Doona trapezifolia, which extends up to about 3000’ above sea level, D. cordifolia, D. macro- phylla, D. congestiflora, which produces a valuable timber, Hofea discolor and Vatica affints. Vatica Roxburghiana is found near streams and in lands subject to inundation in the Western Province and in Sabaragamuwa, while Vateria acuminata, which also loves the neighbourhood of water, is found on more rocky ground. ‘The Dipterocarps which are able to ascend to an elevation of 4000’ are Doona zeylanica and D. Gardnert, and Stemonoporus Gardneri, which has been found up to nearly 5000 feet. Among the natural orders, which are also widely represented, are the Guttifere, the Ebenacee, and the Sapotacee. ‘The first-named is ®epresented chiefly by the ironwood Mesua ferrea and M. Thwaitesi, 360 The Forests and Waste Lands of Ceylon. by Calophyllum spectabile, C. Burmannt, which extends into the dry country, C. bracteatum, C. tomentosum, Garcinia Cambogia, G. Morella. (the gamboge tree), G. derpuophylla, and G. echinocarpa, which latter grows up to 6000’ elevation. The denacece are particularly abundant in the forests of the Adam’s Peak Range, and in the Pasdun and Hinidun Korales. Ebony, as has already been mentioned, is found in small quan- tities in this zone, but the most important tree of this family, which is. unfortunately almost extinct, the Coromandel or Calamander wood of commerce, Drospyros questa, is still found here and there in the Pasdun Korale and in the Hinidun Pattu. Attempts have been made for several years to obtain the fruit in order to propagate the species artificially, but, although rewards have been offered, none has- been obtained. The other most noticeable trees of this family are described by Mr. F. Lewis, who has made a special study of them. In the wet forests, extending from the mountain known as the Haycock into the Sabaragamuwa Province, the most noticeable examples of the Ldenacee are Diospyros Toposia, D. Gardnert, D. insignis, and D. Thwaitesiz. The first of these is found up to 3000 feet altitude, while the last, though endemic, is restricted to- the areas of high rainfall. D. prurdens is found very sparingly in the wet forests towards Adam’s Peak, and in one place in the Western. Province. A remarkable species, possibly a form of D. Ebenum, locally known as ‘ Kallu kiria,’ occurs at the foot of the Rakwana hills, and is conspicuous by its black lace-like heart-wood, but little: is known of its flowers or fruit. One of the most common, but valueless, of the order is D. zwsignis, which extends up to 2000 feet altitude in the West of Ceylon. The Sapfotacee are also well represented, especially in parts of the Matara District. The most importaut are Chrysophyllum Rox- burghit, Isonandra lanceolata, Bassia fulva, B. neritfolia, which. lines the banks of rivers, Palaguium petiolare, P. grande, which extends into the mountain zone, and AZmusops Elengi, which is also found in the dry zone. Among the more noteworthy trees. belonging to other natural orders, the following are characteristic of this zone:—Dzllenia retusa, Wormia triquetra, Cullenia excelsa,. Eleocarpus serratus, Kokoona zeylanica, Canarium zeylanicum,. C. brunneum, Lastanthera apicalis, Pometia eximia, Campnosperma zeylanicum, which in places forms almost pure forest, Perzcopsis Moontana, near water-courses, Adenanthera pavonina, A. bicolor, Pygeum zeylanicum, Carallia integerrima, C. calycina, especially in the Galle District, Anisophyllea zeylanica, Homalium zeylanicum, Symplocos spicata, the three Myristicas (M. laurifolia, M. Hors- fiedia, and M. Iriya). Various species of Czanamomum and Litsea are also abundant; and, among the Euphorbiacee, Bridelia retusa, B. Moonti, Aporosa latifolia, A. Lindleyana, Ostodes zeylanica, Chetocarpus castanocarpus, and Macaranga tomentosa are the most Lhe Forests and Waste Lands of Ceylon. 361 common ; while among Urticacee there are numerous figs, Artocarpus integrifolia, A. nobilis, and Trema orientalts. Among the shrubs which characterise this zone may be men- tioned Humboldtia laurifolia, Mesa indica, Agrostistachys longifolia, A. Hookeri, Ixora coccinea, Ardisia Maen oe Most of the palms of Ceylon are found in this zone. The most important by far is Cavyota urens, the toddy and sugar of which provide many jungle people with means of existence. The Talipot palm (Corypha umbraculifera) is found in several forests, especially in the Kurunegala District, and is noteworthy for the enormous. panicle of flowers which the male tree produces, and for its leaves, which are used for umbrellas, fans, mats, &c. The Misa fruticans is characteristic of brackish waters, while several species of Calamus, with the help of their hooked tendrils, climb to the summits of the highest trees. Among the characteristic climbers may be mentioned Coscinium Jenestracum, Ancistrocladus Vahlii, Entada scandens, Acacia concinna, Strychnos cinnamomifolia. The most beautiful orchid of this zone is the Dendrobium Macarte; and among the most interesting ferns may be men- tioned Gleichenia linearis, which covers large extents of country, Blechnum orientale and Nephrolepis exaltata, which, after the first- named, are the most common, Cyathea sinuata, which is only found in the Southern Province, C. Walkerii, the tree fern of the low country, Zhammnopterts Nidus, the so-called Bird’s-nest fern found growing generally on trees, Asplenium rutefolium, Diplazium lanceum, D. Schkuhrit, Aspidium Thwaztesiz, Lastrea deparioides, Niphobolus Gardnerit, FPleopeltis pteropus (var. minor), Tenites blechnoides (in the Matara District), Drymoglossum heterophyllum, Stenochlena palustris, Polybotrya appendiculata, Gymnopteris vart- abilis, G. contaminans, G. subcrenata, G. quercifolia, Acrostichum aureum (generally not far from the sea in swampy places), Schiz@a digitata, Angiopteris evecta, Ophioglossum pendulum, and HHelmin- thostachys zeylanica. Botrychium daucifolium and Oleandra muse- jolia extend into the mountain zone. The forests of this zone are of by no means so large in extent as those of the dry zone; they usually occur in isolated blocks, covering ridges and separated by stretches of chena or by paddy fields. The most important blocks are the forests that in former days formed part of the extensive Sinharaja Forest; they are situated in the Galle District of the Southern Province, the Pasdun Korale of the Western Province, and the Kukulu Korala of the Province of Sabaragamuwa. The lower forests of the Adam’s Peak range also belong to this zone. The Mountain Zone.—The forests of this zone form the cap of the island. It is from them that all the most important rivers take their rise, and for the preservation of water supply it is therefore necessary that they be preserved. The highest summits of the 362 The Forests and Waste Lands of Ceylon. island, unless they are too rocky for tree growth, are covered with trees, which form a continuous sheet from Pedro Peak to Hakgalla, from thence to Totapella, and in a curved line to Kirigalpota and Adam’s Peak. The forests are found on both sides of the ridges, but the tea estates of Bagawantalawa and Maskeliya have encroached far up the slopes. It is not improbable that to these clearings is due the silting up of the lower reaches of the Kelaniganga, and the consequent frequent inundations which are a plague in the low country. A wise rule now prevails to allow no sale of Crown lands above 5000 feet, and there are not many of these left between 4000 and 5000 feet. ‘The general character of the forests of the mountain zone is the same as that of the dry country; the trees are flat topped, not generally very tall, and the undergrowth is not unlike in general appearance; the most characteristic are several species of Eugenia, Calophyllum Walkerit, Michelia nilagirica, Gordonia seylanica, Elieocarpus obovatus, E. glandulifer, Meliosma pungens, Litsea (5 species), Rhododendron arboreum, &c. The undergrowth consists, especially above 5000 feet, mostly of the numerous species of Szvobzlanthes, which flower and die down every twelve years, and some of which reach a height of 20 feet and a girth of trunk of 12 inches. During the flowering time the forest is a blaze of colour, and swarms of bees, attracted to the flowers, produce abundance of honey, which has a peculiar flavour. When the seed ripens, thousands of jungle fowl suddenly appear wandering up from the low country for the food, which they obtain abundantly. Besides these plants, there are also large quantities of the little hill Bamboo (Avundinarta), species of Coleus, Hedyotts, and ferns, of which the most noticeable and characteristic is the handsome tree- fern Alsophila crinita, which is found in moist places, in gullies, or on the face of moist rocky precipices. The stem of this occasionally attains a length of 40 feet. Among others, the most interesting are Lomaria Patersoni, Lastrea Beddomit, Leptogramme Totta, Osmunda javanica (in sunny places near streams), Déacalpe aspidiotdes, Doodtia dives, and Maranta fraxinea, the last being only found in the lower portion of this zone, replacing Angiopteris evecta, which it closely resembles. The moisture in the atmosphere causes the branches and trunks of trees to be covered with epiphytic plants, such as numerous mosses, ferns, of which some Hymenophyllums closely resemble the mosses, and orchids, the most beautiful of which latter are Dendrobium aureum, Celogyne odoratissima, and Evia bicolor, and creeping plants such as Paper, Medinilla fuchsiotdes, &c. In this zone are found the strange Balanaphoras, which are found at higher elevations only within the Tropics. European genera are found mostly in this zone, but, on the whole, they occur chiefly in well-lit localities, or in patanas, and, excepting Rhododendron arboreum, the majority are shrubs or herbaceous plants, such are Berberis, Cardamime, Viola, Hypericum, The Forests and Waste Lands of Ceylon. 363 Rubus, Viburnum, Anaphalis, Lobelia, Campanula, Gentiana, Pedt- cularis, Drosera, &c. Exceptions to this rule are /mpatzens, of which there are numerous species, some extremely handsome, Vaccinium and //ex, which all grow under shade. This concludes my sketch of the forest flora of Ceylon. It is .a very incomplete one, but with a wealth of species to choose from it is difficult not to omit a number of characteristic ones. To this may be attributed any glaring omissions, as well as to the fact that the writer of this notice can in no way lay any claim to being considered anything botanically but an amateur. A. F. Broun, Conservator of Forests, Ceylon. Colombo, 27 January, 1899. NE Eye ND TG ale ON THE DISTRIBUTION OF THE RAINFALL IN CEYLON. With a Map showing the Average Annual Rainfall. Ly ¥. Lewis, Esq., of the Forest Department. THE island of Ceylon lies to the South-east of the Southern extremity of the great peninsula of India, and is situated between North Latitude 5°53’ and 9°51, and East Longitude 79° 42’ and 81° 55. Its total area is about 25,360 square miles, or, roughly, one sixth less than the area of Ireland. ‘The greatest length and extreme breadth of Ceylon are 271 and 137 miles, respectively. From the Indian coast the island is divided only by a narrow strip of water too shallow for our large ocean steamers to cross, so that vessels bound for the Eastern ports of India are obliged to pass to the South of Ceylon. Although Ceylon has not been entirely free from those great convulsions of the earth which have so strikingly affected Java and neighbouring islands, it must, nevertheless, be regarded as practically outside volcanic action, and beyond the limits of hurricanes. Cyclonic storms have at long intervals visited the country, but none of such destructive severity as to affect the prosperity of the island. The prevailing monsoons are the N.E. and S.W., during which the vegetation of the country passes from rest to activity. The rainfall is heaviest in the immediate neighbourhood of Adam’s Peak, and, speaking generally, diminishes towards the North- west and South-east. Dividing the island into zones, according to the average amount of precipitation, these may be conveniently classified as follows :— (1) The driest zone—under 50 inches of rain per annum— pee of two rather narrow strips; one, starting from the extreme hern point of the island, runs for about 100 miles along the Sous west coast; the other starts from near the Southern extremity and runs along the South-east coast to near Batticaloa Lake. (2) The zone of 50-75 inches is enclosed between the two above-mentioned strips, and includes also the whole North-eastern sea-board (from Batticaloa Lake). This zone comprises the largest area of the country. (3) Enclosed within the crescent formed by the last district is the zone of 75-100 inches, lying roughly along the outside limit of the hill country, this zone forming a sort of elongated horse-shoe band of which the two horns are situated at Colombo and Galle. The Distribution of Rainfall in Ceylon. 365 ‘The inner limit between this zone and the next presents, however, an extremely irregular outline. In this region is found much of the mixed flora of the country, separating the wet from the dry Tegions. (4) The 1oo—-150 inch zone, within the last, comprises most of the mountainous part of Ceylon, including its highest peak. (5) The 150-200 inch zone is a nearly oval region, wholly surrounded by the last, and nowhere quite reaching the sea-coast. At its northern end lies (6) the zone of over 200 inches, a small area within the influence of Adam’s Peak. Here the greater portion of the rainfall occurs during the south-west monsoon, at which period a fall exceeding Io inches in the twenty four hours is by no means uncommon. It will be seen, therefore, that the area of greatest rainfall ‘corresponds with the mountainous country, and is marked by the path of the South-west monsoon, Negombo, 19 miles north of Colombo, with a fall of about 62 ‘inches, being its northern edge, and Galle, with a 91 inch average, being the southern edge of the Maximum monsoon path. Following the tract of maximum fall towards«the great central mass of mountains, the increase is very pronounced, culminating with an average of over 230 inches at Padupola, on the confines of the Central Province. The average temperature of Ceylon varies both with the time of year and the rainfall; but, taking the hottest and coolest stations, it ranges from 81°7’ at Mannar and Jaffna (both on the coast), to 57 9 at Nuwara Eliya (6188 feet above sea-level). The changes in temperature, according to the time of year, may be succinctly illustrated by a statement of the highest and lowest average monthly mean temperature at Jaffna and Nuwara Eliya. At the former the highest monthly average is 85°5’ in April, and the lowest 77°3’ in December; while, at the latter, the extreme averages are 60°4’ in May, and 56°5’ in January. The barometer (uncorrected for sea-level) shows an absolute range from 30°157 inches, the highest recorded in 1887, at Jaffna, to 23°800 inches, in 1886, at Nuwara Eliya. The range at particular localities is small, as will be seen from the appended table, taken from the statistics issued from the Surveyor General’s-Office, which is confined to the sixteen stations possessing umbroken records, in most cases for nearly thirty years. The movement of the atmosphere is much influenced by the distance from the sea. Thus at Kandy, roughly in the centre of Ceylon, the average diurnal velocity of the wind ranges from 28 miles in April to 84 in August. At Hambantota, on the sea-coast, the corre- sponding figures are 149 miles in March, and 268 miles in August. Again, the average diurnal velocity at Vavuniya, which is situated - about midway between the East and West coasts, ranges from 31 miles to 165 miles, while, at Ratnapura, with its high rainfall, it only varies from 18 to 69 miles. 366 The Distribution of Rainfall in Ceylon.

Lewis. APPENDIX IV. HISTORY OF CEYLON BOTANY. By G. 8. Bouucer, F.L.S., F.G.8., Professor of Botany, City of London College. THE first serious student of the botany of Ceylon was Paul Hermann, born at Halle, in Saxony, June 30th, 1646.* It is. related of him that, when a boy of ten, he fell into the water when he was collecting plants and was nearly drowned. He was educated at Wittenberg, Leipsic, and Jena, but graduated in medicine in Padua, in 1670. Through the good offices of Arnold Syen, Professor of Medicine and Botany at Leyden, and annotator of the first volume of Rheede’s ‘Hortus Malabaricus,’ he was introduced to the Governor of the Dutch East India Company, by whom he was appointed ‘Ordinary and First Physician’ in Ceylon, where he resided from 1672 to 1679. On his voyage out he botanised at the Cape of Good Hope, making large collections, some results of which were embodied in a catalogue published by J. Burmann in his ‘ Thesaurus Zeylanicus’ (1647). : At this period the Dutch held most of the coast towns of Ceylon, having wrested Colombo from the Portuguese only so recently as 1655; but the whole interior still remained under the rule of the native Emperor of Kandy, at this time the powerful Raja Singha, and it is interesting to note that our countryman, Robert Knox,t} was undergoing his long captivity in the interior at the very period of Hermann’s sojourn at Colombo.t Dr. Trimen infers from Hermann’s chief herbarium, which is, he says, ‘a representative one of the environs of Colombo, that Hermann neither travelled far from the coast nor had the opportunity of penetrating into any tract of untouched forest.’ In addition to an herbarium sent to Commelin, Hermann sent specimens from Ceylon to other botanists; but certainly not, as Dr. Trimen imagines (af. cit., pp. 132, 134), to Gronovius, since that botanist was not born until 1690, and was, therefore, only five years old at Hermann’s death. Hermann’s plants in the Banksian herbarium received from Gronovius must, therefore, have come to the latter indirectly. Hermann’s own herbarium of plants, collected either wild or growing in the gardens of the natives, was pasted into three * Not 1640, as stated in Pritzel’s. + Vide infra, p. 372. + ‘Journ. Linn. Soc.’ (Bot.), xxiv. p, 131. 368 flistory of Ceylon Botany. volumes ‘in forma atlantica... . sine ullo plane ordine, prout forte ad manus venerant.’* Hermann also had about four hundred drawings of plants executed in Ceylon.t On the death of Syen in 1678, Hermann was elected to the Leyden chair, Peter Hotton { acting as docum tenens until his return to Europe in August, 1680. Hermann introduced into the Leyden Botanical Garden more than twice as many plants as his predecessors, Bontius, Clutins, Pavius, Clusins, Vorstins, Schuylins, and Syen, had done in a century, rendering it the richest of the age.§ He built hot-houses, established a museum, and visited Germany, France, and England for plants. Possibly while in England he made the acquaintance of that ‘Meecenas of his day,’ Dr. Richard Richardson, a letter to whom from him, dated Leyden, 14 December, 1690, is printed in Dawson ‘Turner’s privately printed ‘Correspondence of Richard Richardson’ (Yarmouth, 1835). Hermann arranged the Leyden garden systematically according to Morison’s system, with modifications ‘which can scarcely be called an improvement upon it,’|| including, for instance, JZa/va and fumaria in his primary division of ‘Gymnosperms.’ ‘This system he propounded in ‘Flora Lugduno-Batavz flores, sive enumeratio stirpium horti Lugduno-Batavi methodo naturze vestigiis Insistente dispositarum,’ Leyden, 1690, pp. 267, published under the name of Lothar. Zumbach, but undoubtedly Hermann’s work, as is testified by Sherard,{] Linnzeus,** Haller, Sprengel, Pritzel, &c. Hermann’s classification was defended by his pupil Olans Rudbeck the younger.tt ‘The only work published by Hermann under his own name during his lifetime was ‘Horti academici Lugduno- Batavi catalogus .. . . quibus ab anno 1681 ad 1686 hortus fuit instructus, ....a nemine hucusque editarum,’ Leyden, 1687, pp. 699, 8vo, with copperplate illustrations. A few brief descrip- tions in this work, with reduced copies of some of the drawings made in Ceylon, is all that he himself printed on Ceylon botany. In 1689 William Sherard {{ published at Amsterdam his ‘Schola Botanica,’ pp. 390, 12mo, which the British Museum authorities catalogue under Pitton de Tournefort, and Pulteney and Pritzel attribute to a mythical Samuel Wharton or Warton. Its title runs: * ‘Flora Zeylanica,’ pref., p. 17, and ‘ Museeum Zeylanicum,’ pref. + ‘Flora Zeylanica,’ pref. ~ Born at Amsterdam in 1648, this botanist, one of the correspondents of John Ray, succeeded Hermann in 1695, and died in 1709.

A full account of his life, by Mr. B, D. Jackson, appears in the ‘Journal of Botany’ for 1894, p. 129. fiistory of Ceylon Botany. 369 ‘Schola Botanica; sive Catalogus Plantarum quas ab aliquot Annis in Horto Regio Parisiensi Studiosis indigitavit Jos. Pitton de Tournefort ut et Pauli Hermanri P. P. Paradisi Batavi Prodromus :’ it is signed ‘S. W. A.’ (Sherardus Wilhelmus, Anglus), and the preface is dated London, 1688. ‘The ‘ Prodromus,’ which Linnzeus, in the list of authorities prefixed to the ‘Flora Zeylanica,’ styles ‘supposititius,’ occupies pp. 301-386, with 4 pp. of addenda. In the last yan of his life, Hermann began to print a flora of Leyden. Linneus* styles this ‘Flora Lugduno-Batava, Lugd. 1695, 8vo, seml impressa moritur cum Autore,’ but it has no title, consisting of 128 pp. dealing with ‘ Plantes Gymnosperme.’ Hermann died of pneumonia at Leyden in January, 1695. After his death his widow t seems to have intrusted most of his MSS. to Sherard. The first result of this was ‘ Paradisus Batavus, continens Plus centum Plantas affabre sere incisis & Descriptionibus illustratis . . . . cui accessit Catalogus Plantarum, quas pro Tomis nondum editis, delineandas curaverat Paulus Hermannus, M.D. ; . Opus Posthumum edidit William Sherard,’ Leyden, 1698, 4to, pp. 262, with «rr plates. Sherard’s preface, dated from Geneva, April, 1697, relates the difficulties he met with in reducing the author’s papers into order, and gives an account of Hermann’s other works. The ‘Paradisus’ is dedicated to Bishop Compton, and a critical notice of it, sent by Ray to Sloane, is printed in ‘The Correspondence of John Ray’ (Ray Society, 1848, p. 349). The ‘Paradisus’ contains desenptions and drawings of Sinhalese plants in addition to those in the ‘Horti Lugduno-Batavi Cata- logus,’ but the drawings being in quarto are reduced from the originals. In 1710 Hermann’s ‘ Materia Medica’t was published under the editorship of J. S. Henniger (Argentor. 4to), subsequent editions by J. Boecler appearing in 1726 and 1729, and one by Strother, London, 1736. In 1711 there appeared ‘ Muszei Indici catalogus, continens varia exotica animalia, insecta, vegetabilia, mineralia, quze collegerat,’ 8vo, a catalogue of his museum in the Leyden garden; and in 1717 the important little ‘Museum Zeylanicum, sive catalogus plantarum in Zeylana sponte nascentium observatarum et descriptarum a viro celeberrimo, Paulo Her- manno.,.. , Leyden, 1717, 8vo, pp. 71.- In this pamphlet, to which the term ‘anonymous,’ used by Dr. Trimen (vc. czt. p. 129), seems scarcely applicable, the plants appear under their Sinhalese names, but references to Boccone, Acosta, C. Bauhin, the ‘ Para- disus Batavus,’ and ‘Hortus Lugd.-Bat.,’ are added. In the prefaee the editor, who is well known to have been Sherard, states that, in addition to the three volumes of the herbarium, a fourth would be made up, and pp. 39-71 are occupied by a list of ‘alice * ‘Flora Zeylanica,’ ‘‘ Autores,” and ‘ Bibliotheca’ Botanica,’ ed. 2, p. 58. y+ Anna Gertrude Stomphius, daughter of a pastor of Colombo.

Meanwhile Sherard, anxious to continue Hermann’s work in Ceylon, recommended John Hartog, who was born and trained in the Leyden garden, to proceed thither. At the Cape Hartog collected many rarities, but was only saved from being torn in pieces by a lion by the timely bullet (‘globus missilis’) of his servant’s gun. His Cape plants, with those of Oldenland, form the second of the two catalogues bound up with Burmann’s ‘Thesaurus.’ Though after being some time in Ceylon he sent to Voss the ‘complete’ herbarium which Burmann used for his ‘Thesaurus,’ Hartog seems not to have long survived. Meanwhile Hermann’s own herbarium, upon which the ‘Muszeum’ had been based, appears to have been completely lost sight of till the year 1744, when August Giinther, Apothecary-Royal at Copenhagen,* sent to Linnzus at Upsala to be named a collection of Indian plants in five volumes, one being a volume of drawings. From Ginther, Hermann’s herbarium ‘passed into the posses- sion of Count A. G. Moltke,t at whose death it was purchased by Prof. Treschow, of Copenhagen. The latter sold it to Sir Joseph Banks for 75/7,{ and it passed, with the rest of the Banksian collection, into the keeping of the Trustees of the British Museum in 1827. Since it came into the hands of Sir J. Banks, it has been frequently the object of examination. Especially it was very thoroughly gone over by Dryander, who, in a copy of the “ Flora Zeylanica” (now in the Botanical Department of the British Museum), entered against each species references to the volumes and folios of the herbarium where the corresponding specimens ate toube founds. ghee Robert Brown, Dryander’s successor in the charge of the Banksian collections, was also in the habit of con- sulting the herbarium, and frequently quotes its specimens. Dr. Wight was unfortunately able to consult it only to a limited extent.§ ... . W. Ferguson, F.L.S., of Colombo, when on a visit to England .... carefully examined the whole collection.’ || The results of Dr. Trimen’s own detailed work in 1886 are embodied in the paper from the introduction to which this passage is taken. He says of the herbarium (oc. ct, p. 132), ‘The specimens, considering their age and the vicissitudes the collection has sustained, are in very fair condition; and, in the few cases where identification is uncertain, this arises more from the material being originally scanty or imperfect than from any deterioration * There are five letters from Giinther to Linnzeus in the corre§$pondence of the great naturalist preserved in the library of the Linnean Society.

B71 “since its collection. A considerable proportion of the plants (about fifty) are exotics, and gathered, doubtless, from gardens. It is of interest to see at what an early date many of these were already common in Ceylon. Most are, of course, Old World plants, but -a dozen or more are of American origin, as the Custard Apple, Guava, Cashew-nut, Capsicum, and Cotton. But, besides these cultivated exotics, the list will be found to contain two or three species from the Cape.’ Of these errors, arising from Sherard’s fourth volume, those originally ‘non-agglutinatee,’ he specifies Linneus’s 4obartia indica, which is SB. spathacea, Ker, and Gnaphalium indicum, L., which is Amphidoxa gnaphalodes, DC. Carl von Linné. As stated under the notice of Hermann’s life and labours (ante, p. 370), the herbarium and collections of drawings of the latter were sent to Linnzeus to be named. ‘The great botanist was not long in discovering what a treasure he had in his hands.* In his own words, ‘ Hanc dum evolvo, examino et inquiro, observo plantas hasce per tres primos tomos, in singulis paginis totidem, easdem, eodemque ordini esse dispositas, quo in Hermanni ‘ Museo Zeylanico’ continentur a p. 1 ad 39; accedebat quod /cones, quas quintus tomus continet, essent ipsius Hermanni.... ut dubium nullum sit, quin heec collectio fuerit ipsissima Hermanni. Quartus tomus continebat plantas Capenses et Zeylanicas mixtas ’ |—Sherard’s ‘non agglutinate’ in fact. The delight with which Linnzus at once set to work at the examination of his treasure is well expressed in the following passage from his dedication of the ‘ Flora Zeylanica’ to Ginther: ‘Gratulor orbi erudito, quod hic Thesaurus, qui per 50 annos fuerat suppressus, indignorum manibus versatus, & in Barbarorum hominum scriniis sepultus, rerum vicissitudine iterum emerserit & ab interitu fuerit vindicatus. Est hoc opus Herbarium Zeylanicum, quondam a Principe Botanicorum, Paulo Hermanno, lectum in Zeylona multis itineribus, periculis, laboribus, curis, nec sine Foederati Belgii maximis sumtibus.’ t The ‘ Flora’ was publishea at Stockholm,§ in 1747, its full title being ‘Flora Zeylanica sistens plantas indicas Zeylone insule que olim 1670-1677 lectz fuere a Paulo Hermanno, Prof. Bot.

In it ‘ Linnzus has classified all the plants in the herbarium which he could determine (429 in number) under their genera; and these are duly arranged in accordance with his sexual system.

In the herbarium itself he has added to Hermann’s labels a reference to the number of the species in his own copy of the “ Flora Zeylanica ;”’ and in his own copy of the ‘Museum Zeylanicum,’ now in the Linnean Society’s library, ‘he has entered in the margin against each name the genus to which he referred it.’* ‘At this period of Linnzeus’s career he had not yet initiated his binomial system of nomenclature; thus no species in the “‘ Flora Zeylanica” are zamed in the modern sense, but are only referred to their Linnean genera. When, however, in 1753, that really epoch-making book, the ‘‘ Species Plantarum,” was published,. in which specific names were systematically employed, Linnzeus was careful to quote under them the numbers of the “Fl. Zeylan.,” and thus the specimens of Hermann’s herbarium become types for many of Linneeus’s species. It is this, of course, which gives to this in- teresting collection its great scientific value, and renders it an important supplement to the herbarium of Linnzeus himself... .; especially as the large majority of the species in Hermann’s her- barium are unrepresented in the latter.’ { A second edition of the ‘ Flora’ appeared in 1748, to some copies. of which is appended ‘ Nova genera plantarum zeylanicarum nuper edita .... per C. M. Dassow, pp. 1-14, with an index.’ This is. taken from the ‘Amoenitates Academice,’ vol. i1., No. 13, and is, no doubt, Linnzeus’s own work. ‘The forty-three new genera here described were afterwards incorporated into the fifth edition of the ‘Genera Plantarum,’ published in 1754;{ but Dr. Trimen does not refer to them in the paper from which we have been quoting. Robert Knox, the first Englishman to publish an account of Ceylon, was born in 1640 or 1641, being the son of Robert Knox, a Scotsman, a commander in the East India Company’s navy, and a cousin to John Strype, the antiquary. Knox was brought up at Wimbledon, Surrey, where his mother died about 1655, and in January, 1657, he sailed with his father to Madras. On the home- ward voyage, in November, 1659, they were driven by stress of weather into Cottier (Kottiyar) Bay, Ceylon, where Knox, his father, and fourteen others were made prisoners. The father died in captivity in 1660; but Knox remained a prisoner at large for nearly twenty years, making several unsuccessful attempts to escape, and supporting himself by knitting caps, lending out corn and rice, and hawking goods. In September, 1679, with his faithful comrade, Stephen Rutland, he escaped to the Dutch settlement of Aripo, on the north-west coast, whence he was sent to Batavia, and so to England. The East India Company took him into their service as. mate: he rose to be commander, and died in London, July, 1720.

Johann Gerhard Konig, a pupil of the illustrious author -of the ‘Flora Zeylanica,’ collected in the island in 1777, 1780, and 1781. Konig was born at Courland about 1728. He visited Iceland in 1765; but from 1768 was in the East Indies until his death at Jagannathpur in 1785. He was at first physician to the Danish settlement in the Carnatic, and subsequently naturalist to the Nabob of Arcot, and, in 1778, joined the Madras establishment of the East India Company. He also collected in Siam and Malacca, and bequeathed his plants and MSS. to Banks; but his Ceylon journal was unfortunately lost.* There is a short account of Konig’s visits to Ceylon in August Hennings’s ‘Geschichte ‘des Carnatiks,’ Hamburg and Kiel, 1785, pp. 289-311. Konig’s name has been twice commemorated ; by Tournefort for a genus of Malvacee prenamed Dombeya, and by Linnzus for an arctic plant now merged in Polygonum. Carl Peter Thunberg, the pupil and successor of Linnzeus, ‘was in Ceylon from August, 1777, to February, 1778. He was born in 1743, graduated as M.D. at Upsala in 1770, visited the Cape in 1771, Java and Japan (1774-1777), his visit to Ceylon being on his return journey. He became professor at Upsala in 1784, and died in 1828. From the British seizure of the Dutch possessions in 1796, when they were annexed to the presidency of Madras, until 1801, when Ceylon became a Crown colony, nothing seems to have been done for botany; but, before the deposition of the King of Kandy in 1815, William Kerr, a Kew gardener and collector, who had previously been in Java, Canton, and the Philippines, was appointed, by Sir Joseph Banks, Superintendent of the Botanical Garden at Slave Island, Colombo. He was, in fact, appointed in 1812, but -died in 1814. In 1817, Alexander Moon, a Scotsman, was appointed, by Sir Joseph Banks, Superintendent of the Gardens. He collected at Gibraltar and on the Barbary coast on the way out, and formed -an extensive herbarium at Peradeniya. In 1824, he published “Indigenous and Exotic Plants growing in Ceylon,’ Colombo, 4to, = Britten and eae: ‘ Biogr. Index of Brit. and Irish ns. Supplement,’ 0p.

Arnott dedicated to him the genus d/oonza, now sunk in Chrysogonum, L. James Iiacrae, who had been employed in the garden at St. Vincent in 1823, and had subsequently collected for the Horti- cultural Society in the Pacific, in Chili, and Bengal, was appointed Superintendent in 1827, but at his death, in 1830,¢ had not, appa- rently, much advanced the cause of botany in Ceylon; nor, in fact, was much likely to be done until a more highly educated type of man was appointed to the post. Meanwhile, amateur work was doing something. Colonel, after- wards General, James Thomas Walker and his wife, Mrs. A.W. Walker 7é Paton, collected in the island from 1830 to 1840. A description of their ascent of Adam’s Peak appears in the ‘Com- panion to the Botanical Magazine,’ vol. i. (1835), p. 3; and a ‘Tour in Ceylon,’ by Mrs Walker, in Hooker’s ‘ Journal of Botany,’ 1840, p- 223. General and Mrs. Walker’s plants formed part of Sir W. J. Hooker’s herbarium, now at Kew, and also did those of his friend, Dr. Charles Millett, who, about 1834, collected in Southern China, in Ceylon, and on the Malabar coast,{ and those of Major, afterwards Lieut.-Colonel, Champion. Dr. Robert Wight, F.R.S., born in East Lothian, :796,. graduated M.D. in Edinburgh in 1818. Entering the East India Company’s service as Assistant-Surgeon in the army, he was from 1826 to 1828 stationed at Madras, and from 1836-1850 was. Superintendent of the efforts of the Government for the improve- ment of cotton cultivation in the peninsula. During three years’ furlough in England (1831-1834), he began, in conjunction with Dr. Walker-Arnott, the publication of his botanical materials, especially in the ‘Prodromus Flore Peninsule Indiz Orientalis.” In 1836 a severe attack of fever, caught in Tinnevelly, obliged him to pay a short visit to Ceylon to recruit, and whilst there he collected. extensively in company with Colonel and Mrs. Walker, in compli- ment te the latter of whom he named the genus /afonza, now merged in Xylopia, L. It was during this furlough above mentioned, that Dr. Wight, when staying with his friend, Sir W. Hooker, at Glasgow, acquired the art of lithography, and providing: himself, at his own expense, with printing-press stones and all necessary materials; he on his return to India introduced the art into the Madras Presidency, and commenced his ‘Illustrations of Indian Botany,’ with 182 plates, which was followed by the ‘ Icones. * Sir J.

In 1853, after a residence of upwards of thirty years in India, during which he had published in the above-mentioned and other works nearly 3000 species of Indian (including Ceylon) plants, he retired from the service, returned to England, and took up his abode at Grazeley Lodge, near Reading, where he died, May 26th, 1872. His collection he presented to the herbarium of the Royal Gardens, Kew. Wghtia gigantea, a remarkable Nepalese scandent tree, of the Order Scrophularinee, was dedicated to his services by Wallich. John George Champion, F.L.S., was born about 1815, and in 1831 was gazetted as ensign in the g5th. He embarked for active service as captain in 1838, was stationed for some time in the Ionian Islands, where he collected insects diligently, and subsequently in Ceylon, where he took up botany under Gardner, remaining there until 1848. He then proceeded to Hongkong, whence he returned to England in 1850, bringing with him a fine collection of plants from that island, which were described by Bentham, and afterwards incorporated in the ‘Flora Hong- kongensis.’ In 1853 Champion went with his regiment to the Crimea. Having been wounded at the battle of Inkermann, and taken to the hospital at Scutari, he was gazetted lieutenant-colonel, but died November 3oth, 1854. He is commemorated by the Sinhalese genus Champzonia, Gardner. Almost coincident with Colonel Champion’s arrival in the island in a military capacity was that of another energetic amateur, who came as a civilian, William Ferguson, who, born in 1820, entered the Ceylon Civil Service in 1839, and, with the exception of short furloughs, remained there until his death, which took place at Colombo on July 31st, 1887. He devoted his leisure to botany and entomology, and his knowledge of the plants and insects of Ceylon became most intimate. Many of his papers appeared in the ‘Ceylon Observer’ and in the ‘Tropical Agriculturist.’ He published, at Colombo, ‘The Scripture Botany of Ceylon, nd; ‘Description of the Palmyra Palm (Gorassus flabelliformis, L.),’ 1850; ‘The Timber Trees of Ceylon,’ 1863; ‘Notes on Ceylon Ferns,’ 1880; and, in the ‘Journal’ of the Ceylon branch of the Royal Asiatic Society, an ‘Enumeration of Ceylon Grasses, with notes,’ 1880. He is commemorated by the monotypic genus Pergusonia, Hook. fil., in the Order Rudzacee. A new era seemed about to dawn for Ceylon botany when, in 1843, Dr. George Gardner was, on the recommendation of Sir William Hooker, appointed Superintendent of the Botanical Garden of Peradeniya. Born in Glasgow in 1812, he had studied medicine in the university of that city, graduating M.D. in 1835. Having 376 fTistory of Ceylon Botany. conceived a strong desire for botanical travel, with the assistance of his teacher, Sir W. J. Hooker, he started on a collecting expedition to Brazil, from which country he sent home 60,000 specimens, representing 3000 species, while his own collection comprised 6000 species of flowering plants alone, and he brought back with him to England, in 1841, a large number of living plants. His journal appeared in the ‘Companion to the Botanical Magazine’ and in the ‘Annals of Natural History,’ and the descriptions of his new genera in the ‘Journal of Botany’ A more detailed account of this journey, having been prepared by him on the voyage out to Ceylon, was published in 1846 as ‘Travels in the interior of Brazil.’ Gardner showed his energy by issuing, four months after his arrival in Ceylon, the first of those reports on the Garden which have since then been continued annually. In 1845 he visited Madras, and botanised in the Neilgherry Hills with Wight, in conjunction with whom and Dr. M‘Clelland he became editor of the ‘Calcutta Journal of Natural History.’ In this journal he was writing “Contributions towards a Flora of Ceylon’ during the last year of his life, and he also drew up, in 1848, ‘Some Remarks on the Flora-of Ceylon,’ which were printed in the appendix to Lee’s translation of Ribeyro; but his premature death from apoplexy, at Nuwara Eliya, on March roth, 1849, destroyed the hopes that had been built upon his great capacity. Gardner’s herbarium, com- prising 14,000 specimens, was mostly purchased by the British Museum. His name is commemorated by the Leguminous genus Gardneria, Wallich. On Gardner's death his place was taken, also on the recom- mendation of Sir William Hooker, by a botanist who had already achieved a singular reputation, George Henry Kendrick Thwaites, F.R.S., who probably has done more for our scientific and practical knowledge of the vegetable products of (eylon than any one man. ‘Thwaites was born at Bristol in 1811, and began life as an accountant, devoting his leisure impartially to entomology and microscopical botany, chiefly that of the cryptogams. His earliest paper was ‘Notes on a Species of Stylops’ (an insect parasitic on the bee), written in 1838, though not published till 1846 (‘Trans. Entomol. Soc.,’ vol. i.), and he never abandoned entomology. He was so recognised as a com- petent biologist as to be engaged by his fellow townsman, Dr. W. B. Carpenter, to revise the second edition of his ‘General Physiology’ in 1841. In conjunction with Christopher Edmund Broome, he investigated the structure of truffles: his earliest botanical note, contributed to the ‘ Phytologist’ in 1841, was on the occurrence of Asplentum lanceolatum near Bristol; and his first paper of importance was one ‘On the Occurrence of Tetraspores in Alge’ in the ‘Annals and Magazine of Natural History’ for 1846, which was followed by others, mostly phycological, in the same magazine. An acute observer and expert microscopist, fistory of Ceylon Botany. 377 sspecially skilful in preparing microscopic objects, at a time when students of the structure of cryptogams were so few in England that many of his discoveries were overlooked and subsequently. _attributed to later Continental workers, his most important obser- vations at this period were those on the conjugation and algal nature of diatoms—organisms which had till then been generally regarded as animals. This discovery led Montagne to dedicate to him in 1845 the algal genus Zhzwaztesca. He worked also at -desmids and lichens; but that he did not confine his attention to cryptogams is shown by his communicating a list of the flowering plants within a ten-mile radius of Bristol to Hewett Watson for his ‘Topographical Botany.’ He was also one of the early contributors to the ‘Gardeners’ Chronicle,’ one of his first discoveries with a direct bearing upon horticulture being the raising of two distinct varieties of /uchsia from the two embryos in a single seed. In 1846 he became lecturer on botany at the British School of Pharmacy and Medical School, and in the following year was, like Watson, an unsuccessful candidate for a natural history chair in -one of the new Queen’s Colleges in Ireland. Directly he reached Ceylon, which he never left till his death, he devoted himself to the investigation of the flora of the island, -and for fifteen years he almost ignored his favourite Cryptogamia. Until 1857 his duties were mainly scientific, and between 1852 and 1856 he contributed numerous descriptions, with drawings and -analyses, of Sinhalese phanerogams to Hookers ‘Journal of Botany,’ including twenty-five new genera. In 1857 the title of his office was changed from Superintendent to Director, and he became yearly more and more engrossed by the less congenial duties -of investigating the application of botany to tropical agriculture. It is hardly surprising that the lay mind, becoming aware of the absence of any adequate enumeration of Ceylon plants, and unable to appreciate the thoroughness of Thwaites’s method, should grumble. ‘Thus we find Sir J. Emerson Tennent writing in 1858: ‘Up to the present time the botany of Ceylon has been imperfectly submitted to scientific scrutiny. ... . It may be mentioned as a fact which is much to be regretted, that, although botanists have ‘been appointed to the superintendence of the Botanic Gardens at Kandy, information regarding the vegetation of the island is scarcely obtainable without extreme trouble and reference to papers scattered through innumerable periodicals. That the majority of Ceylon plants are already known to science is owing to the coincidence of their being also natives of India, whence they have been described ; but there has been no recent attempt on the part of colonial or European botanists even to throw into a useful form the already published descriptions of the commoner plants of the island. Such a work would be the first step to a Sinhalese flora. The prepara- tion of such a compendium would seem to belong to the duties of ‘the colonial botanist, and as such it was an object of especial 378 Ffistory of Ceylon Botany. solicitude to the late Superintendent, Dr. Gardner. But the heterogeneous duties imposed upon the person holding his office . ... have hitherto been insuperable obstacles to the attainment Giethis object. 2. h. ‘P.S.—Since the foregoing passage was written, Mr. Thwaites has announced the early publication of a new work on Ceylon plants, to be entitled “Enumeratio Plantarum Zeylaniz; with Descriptions of the New and Littleknown Genera and Species ;” and observations on their habits, uses, &c. In the identification of the species, Mr. Thwaites is to be assisted by Dr. Hooker, F.R.S., and from their conjoint labours we may at last hope for a production worthy of the subject.’* Thwaites, in fact, began the printing of the ‘Enumeratio,’ his. only independent book, in the very year, 1858, in which Tennent wrote, the work being issued in five fasciculi, between 1859 and 1864, and containing in all 483 pages, 8vo. It contains descriptions in Latin of many new species, and Thwaites acknowledges the assist- ance he had received in the identification of the species, and in the synonymy, from Dr. (now Sir Joseph) Hooker. On the completion ot the work, he was elected a Fellow of the Royal Society, and received the degree of Doctor of Philosophy from the Imperial Leopoldo-Carolinian Academy, whilst, in 1867, the beautiful genus of Sinhalese climbing plants, Kenxdrickia, Hook. fil., was dedicated to him; but he never himself considered his work as more than a prodromus to a complete flora, or a catalogue to the extensive sets. of exsiccatee which he distributed. It is worthy of note that in the preface to the ‘Enumeratio,’ dated 1864, Thwaites announces his. adhesion to the Darwinian view of the nature of species. In 1860, Thwaites had established the cinchona nurseries at Hakgala, the subsequent success of the cultivation of these plants in Ceylon being largely due to his efforts. His successive annual official reports deal also with the cultivation of vanilla, tea, cardamoms, cacao, and Liberian coffee. In 1869, he sent to the Rev. M. J. Berkeley the first specimens of the coffee-leaf fungus (Hemileca vastatrix); and his reports from 1871 to 1880 —in some of which he was assisted by Dr. Morris, C.M.G., F.L.S.,7 and Dr. H. Marshall Ward, F.R.S.f —deal with it and the suggested preventives, repudiating, in face of much adverse popular opinion, any hope of external cures. After the completion of the ‘Enumeratio,’ ‘Thwaites returned to the study of cryptogams, sending home more than 1200 fungi, which were described by Messrs. Berkeley and Broome,§ besides mosses, which were published by Mr. Mitten in 1872, and lichens, some of which were described by the Rev. W. A. Leighton in 1870.

Fistory of Ceylon Botany. 379 1879 to take his place, he in the following year retired on a well- earned pension, and purchased the pretty bungalow named ‘ Fairie- land,’ above Kandy. While in Kandy, on his way to the seaside, Thwaites died, September 11th, 1882. He had been an F.LS. since 1854, and a C.M.G. from 1878. A portrait of him accom- panies a brief memoir in the ‘Gardeners’ Chronicle’ for 1874, vol. 1. p. 438. Among those who assisted Thwaites, we can only mention three other names, those of Harmanis De Alwis, George Wall, and the Rey. S. Owen Glenie. Harmanis de Alwis Seneviratne _ joined the staff of the Ceylon Garden in 1818 as a writer under Moon (the second Superintendent) at the old Gardens in Slave Island, Colombo, and at Kalutara, assisting him in the preparation of the ‘ Catalogue of Ceylon Plants’ (1824). Perceiving De Alwis’s aptitude for drawing, Moon had him taught at his own expense. ‘In 1821, the Gardens were moved to Peradeniya, and two years after, in 1823, De Alwis was appointed draftsman, a post he con- tinued to hold for thirty-eight years. He at once commenced, under Moon’s direction, the coloured drawings of Ceylon plants which have now become so large and valuable a series. So well did he do his work, that Governor Barnes, in 1831, conferred on him the native rank of Muhandiram.’ When, in 1836, Wight visited Ceylon, he was so interested in De Alwis’s drawings, that, in 1839, he had him for three months at Madras, to learn floral dissection and draw some of the plates of the ‘Icones Plantarum Indize Orientalis.. ‘When Gardner arrived as Superintendent of the Gardens, he found already a good series of drawings, which, under his auspices, rapidly increased in number and aceuracy, it being Gardner’s practice for the artist to accompany him in all his botanical tours. Dr. Thwaites followed the same plan, and, in the preface to his “ Enumeratio,” acknowledges De Alwis’s “intelligent and hearty co-operation” in the work. In 1854, an assistant drafts- man was also at work in the person of one of the sons of De Alwis, and, in this year, the rank of Mudaliyar was bestowed on him by Governor Anderson. In 1861 he retired on full pension, which he lived to enjoy for thirty-three years in the complete possession of his memory and his senses, with the exception of failing eyesight. De Alwis died at Peradeniya, June roth, 1894, at a very advanced age. His name is commemorated in a very curious and minute leafless orchid, which he was the first to discover, and which was named after him in 1859, by Dr. Lindley, Zeniophyllum Alwisii. Dr. Lindley also named another little orchid A/wisia tenuis.* George Wall, F.L.S., born about 1821, went to Ceylon in 1846, where, as a leading merchant, planter, newspaper editor, and member of the legislative Council, he occupied a pro- minent position. He was an intimate friend of Thwaites, and took * H. Trimen, ‘Journ, Bot.,’ 1894, pp. 255-6. 380 fiistory of Ceylon Botany. up the study of ferns with an enthusiasm that characterised all his actions. He formed an extensive herbarium of the ferns of the world; and, in 1874, he arranged the large collection of exotic species in the Peradeniya herbarium, to which he added from his own collection. He was the author of two privately printed pamphlets on the ferns of Ceylon, ‘A Catalogue of the Ferns indigenous to Ceylon, with Notes by G. W.,’ London, 1873, 4to, and a Check List, printed in 1879. He became a Fellow of the Linnean Society in 1872. He died at St. Thomas’s Home, London, December 18th, 1894, a few days after his arrival in England from Ceylon. His name is commemorated in Zrichomanes Waltz, Thw., described in the ‘Journal of Botany’ for 1885, p. 274, and dis- tributed as C. P. 3989.* The Rev. S. Owen Glenie was Colonial Chaplain at Trin- comalee, and collected for Thwaites. He became a Fellow of the Linnean Society in 1863, and the monotypic Sinhalese genus of Sapindacee Gleniea, Hook. fil., is dedicated to him.t Mention should perhaps here be made of a German descriptive work by Baron Eugen von Ransonnet-Villez, entitled ‘ Ceylon.

Oln Cevloniam dias is a narrative of travel, including a visit to Thwaites at Peradeniya, illustrated by twenty-six large drawings lithographed by the author, about half of which represent the vegetation of the island. Henry Trimen was born in Paddington, October 26th, 1843. While still at King’s College School he began to form an herbarium, and in 1860 entered the medical school of the College. After spending one winter at Edinburgh University, he graduated as M.B. with honours, at the University of London in 1865. Shortly afterwards he acted as medical officer in the Strand district, London, during an epidemic of cholera, but his inclinations were obviously towards botany rather than medicine. He had become a member of the Botanical Society of Edinburgh in 1864, and in London took an active part in the Society of Amateur Botanists and the Botanical Exchange Club. From 1866 to 1869 he was engaged, in conjunction with Mr. (now Sir William) Thiselton Dyer, in the preparation of the ‘Flora of Middlesex,’ a work which ever since its publication in the latter year has been regarded in England as the model for county floras. Devoted from the first to the study of critical groups of plants, such as Rumex and Polygonum, he, in the year in which the ‘ Flora’ was published, added to the British list Wolfia arrhiza, the smallest of flowering plants, which happens to be also a native of Ceylon. In the same year he became an assistant in the Botanical Department of the British Museum, -* ‘Journ. Bot.,’ 1895, p. 63. ++ Thwaites’s ‘ Enumeratio,’ p. vil. fiistory of Ceylon Botany. 381 and, after having for some time aided Dr. Seemann with the ‘Journal of Botany,’ became its assistant editor in 1870, and on Seemann’s death, in the following year, succeeded him as editor. From 1875 to 1880 he issued, in conjunction with the late Prof. Robert Bentley, his second important work, ‘Medicinal Plants,’ which appeared in forty-two parts, and contains coloured figures of most of the species in the Pharmacopceia. For some years Trimen also acted as lecturer on botany at St. Mary’s Hospital. The zeal with which, on his appointment as Director at Pera- deniya in 1879, he took up Thwaites’s work was seen in the thorough rearrangement of the plants in the Gardens in scientific order, in much work at economic botany, especially quinology, recorded in his annual official reports, and in a diligent exploration of the island for materials for the present work. He published eitomus. Zeylanicus: A... . List of the Plants .... in the Royal Botanic Gardens, Peradeniya,’ in 1888, a ‘Catalogue of the ipisiye.)..-, in rds9, and -a. “Hand-Guide to the... . Gardens,’ in 1890, of which the last-named reached a fourth edition in 1894, whilst reference has also been made to his careful work upon Hermann’s herbarium whilst in England in 1886. The climate of Ceylon, however, seems to have proved fatal to him. He aged prematurely, became totally deaf, and was partially paralysed; but, after being again in England during 1895, he insisted on returning to Ceylon, hoping to finish the ‘ Hand-book,’ the publication of which had begun in 1893. ‘Trimen died at Kandy, October 16th, 1896, and was buried near his predecessor in the Mahaiyawa Cemetery. His name was given by Dr. King, of Calcutta, to the magnificent Sinhalese banyan, Fzcus Triment. The memoir by Mr. James Britten in the ‘Journal of Botany’ for 1896 (pp. 489-494), from which most of the above is taken, is accompanied by a portrait from a photograph, but his best memorial in the history of botany in Ceylon is undoubtedly the present work, though he did not live to compiete it.

Its thallus is like that of Farmeria, but it has the fl. of Podostemon; its fr. splits into two unequal valves.
