INTBODUCTION. EARLYin April of last year Mr. M. T. Dawe, Officer in Charge of the Forestry and Scientific Department of the Uganda Protectorate, started with the sanction of the then Acting Commissioner for Uganda, Mr. George Wilson, from his head- quarters at Entebbe, on an expedition through Buddu and the Western and Nile Provinces of the Uganda Protectorate. The object of the expedition was in the first place the exploration of the forests of the districts mentioned, and secondly a general botanical survey of the country traversed. After an arduous and extremely successful journey, Mr. Dawe arrived at Gondo- koro late in November of the same year, when his mission came to an end and he went home on leave. A complete set of his collections had meanwhile in several instalments reached Kew via Entebbe. They were taken in hand as they arrived, and with his active assistance it was possible to supply him early in the present year with a list of the names of the plants collected by him. An account of his expedition, including an enumeration of the plants of his collections, was published as a Blue Paper last April under the title ‘‘Report on a Botanical Mission through the Forest Districts of Buddu and the Western and Nile Provinces of the Uganda Protectorate I’ (London, H.M. Stationery Office ; Cd. 2904), pp. 1-63, and 5 plates. As it was desirable that the report should be published without delay, it was not possible to work out the descriptions of the numerous new species in time to be included in the report. Thus a considerable number of “ nomina nuda ” found their way into it, and it is the object of the present paper to supplement the report in that respect by adding the necessary technical descriptions. As Mr. Dawe’s official report may not be generally accessible, 496 DR. 0. STAPF-PLANTE NOVB I suggested to him that it would be usef‘ul to have a condensed account of the principal features of the vegetation of the districts visited. He was good enough to supply tne with what is really a summary of the botanical contents of his report, with some additional information on the climatic conditions and the general nRture of the country. He also added a sketch-map to illustrate the route of the tour, the location of the districts, and the distribution of forest and open land. I propose to add Mr. Uawe’s contribution as an appendix to our joint paper. I would fain have introduced a more definite ecological terminology similar to that used by Professor Engler in his valuable contributions on the [)]ant geography of Tropical, and particularly of East Africa, so as to facilitate comparioon. I found, however, I could not do it without a greater loss of time than I could afford, or the risk of misrepresentiug Mr. Daae’s statements, and confined myself therefore to a few purely editorial alterations. I would, however, observe that a uniform and classified terminology is as desirable for the description of the vegetation of a country as it is necessary, for instance, for that of morphological objects, although, of course, it can never claim the same degree of precision owing to the complication and diversity of the conditions which determine the character of a vegetation. I may be allowed to add a few words of’ appreciation of the scientific results of Mr. Dawe’s expedition. They consist, firstly, in the addition to science of a considerable number of new types. They are by no means exhausted in the present paper, wliich, as I have explained, is mainly intended to give a locus standi to the new names introduced into the report. Others which are not specially mentioned because they were not of‘ sufficiect importance for the purposes of the report, or would have required too extensive researches, will follow as time permits and occ*asioo arises. Then there are a great many species which, although already known, are new to the provinces visited by Mr. Diiwe. As to them L must refer to the enumeration in the official report. Of equal value is Mr. Dawe’s attempt at a more precise circum- pcription of the forest areas in the Equatorial Lake Region aiid their analysis. In both respects our knowledge wm so far of the most general character. That part of his work is particularly interesting in regard to the West African element present, a fartor the importance of which in its bearing on the history of DAWEME IN UGANDA LECTZ. 497 the African Contiuent liw already been pointed out twelve years ago by Dr. Stuhlniann in his suggestive summary in the conclud- ing chapter of his work ‘With Eniiri Pasha in the Heart of Africa.’ Thus fait Mr. Dawe’s account also supplements the survey work of the botanist of the Anglo-German Boundary Commission, the results of which were issued in no. 269 of the Journal of this Society last year. It was indeed very tempt- ing to follow up by means of &. Dawe’s collections the question of the exteut and character of the West African Hylaea element in the heart of Atrica, or that of the remarkably mixed higliland flora of Mt. Ruwenzori; but this woiild have required an extensive revision of all the material available from that region, and Ltius wideued the scope of this paper far beyond reasonable limits. M.y own and niy collaborators’ shares in the descriptive part of the paper are evident from the authors’ names after those of the species ; but I ought to mention that a not inconsiderable part of the preliminary work of comparing Mr. Dawe’s collection was done by Mr. J. Hutchinson, temporary Assistmt at Kew.

Toro: Kibale Forest, 1300 m., Uawe, 510. Native name, “ Masuko.” W. ugandensis appeared in Mr. Dawe’s Report under the provisional name Dawea ugandensis, Sprague (gen. nov. Bix- acearum). Further exnmination has proved it to be one of the Canellaceae, and although it differs from Engler’s and Warburg’a descriptions of WarbuTqia in liaving the ovulee biverintely arranged on the placentse and in the subcapitate stigma, it seems desirable to refer it for the present to that genus.-T. A. S.

Mr. L. A. Boodle, F.L.S., has kindly supplied the following account of the anatomy of W. ugandensis. An examination of the structure of this species gave the followiug results. Secretory cells are present in the palisade and spongy tissue of the leaf, in the petiole, and in the cortex, phloem, and pith of the stem. In the wood there are vessels with long scalariform perforations, iiarrow medullary rays (1-2 cells broad), and wood-prosenchyma Rith very distinct bordered pits. The periderm is superficial, and the cork-cells have thin walls. The medullary rays in the phloem increase in breadth from within outwards. The petiole contains three vascular bundles. In all these features the anatomy agrees with that of the American genera of Canellaceae, as summariaed by Solereder (Syst. Anat. Dicot. p. 97), and according to Eirgler (Pflanzonw. Ost-Afr. C. 276) a similar structural agreement is shown by Warburgia Stuhlmannii, Engl. It is specially interesting that there should be such a close similarity in structure between the American and African generii of this Order. Segarding one feature in K ugandensis, Sprague, I cannot speak definitely ; thickening of the iuner ~allsin the phelloderm had only begun in a few cells, hence it Kould be necessary to examine older specimens of the stem, to determine whether the phelloderm o:ibsequently zmirnea the structure typical of the Order.- L.

It is suspected to be a galled condition, as no traces of fungi are present. Mr. Brown describes the fruit as yellow and inedible, but all those collected are iri the same condition.

Mr. Dane collected both floffering aud fruiting specimens, DkWEANX 1N EGLNDA LECT.E. 517 and the latter are indistinguishable from those collected by Speke and Grant, hence they are provisionally referred to a siiigle species, which is quite distinct from the Senegambiaii 1: mncroptera, Guill. et Pvrr. Col. Grant describes the species au s fine, large, hniidsoiue tree, 10 to 12 feet circumference of trunk, ~itlithe old bark hard, black, and fissured, and the young marbled red and grey, and the wood lemon-yellow and watery when fresh. The leaves grow in tufts from the tips of the branches. The kernel of the fruit eats as sweet as an almond. He further remarks that it is called ‘. Wfoof’oo,” and that the natives use it for tinting their cloths (made of‘ bark) a yellow colour, and that the Arabs make supports for their houses of itu \\ ood.

The affinity H ith Oldenlandia rotata, Baker, is quite evident ; but a close esainiriatioii of the geiiua Oldeialalzclia will probably result iii the breaking up of the genus into several genera, one of which would be Cono- stonzzunt. As it stands at present, it includes plants which differ considerably not only in general appearance, but more particularly in the structure of the fruits and seeds. I’he flowers of 0. rotata are diHtinctly heterostylous. The corollas of the inacrostglous form hare a slightly larger limb with broader lobes and a very short funnel-shaped widening at the base, the stigma tips just reaching to where this widening begins, uhilst the authers surround the base of the slender stigmatic lobes. In the brachystylous form the stigma-tips are about 6 mm. below the mouth of the corolla-tube, which is scarcely widened and irom which the upper half of the sessile anthers are exserted. On the other hand, all the floivers of 0. dolichalztha which I examined were alike and as described above.

Afr. vol. iii. p. 42, although the latter has much broader leaves almost soft to the touch, the hairs being few and not rigid. Oliver’s description of the inflorescences as lateral rests evidently on a misconception of Grant’s note, quoted in the Trans. Linn. SOC.1. c., there being with Grant’s specimen only a detached branch of an inflorescence in the Kew Herbarium. Grant says “ A fruit-bearing brauch grows opposite a lrsaf-bearing one.”

Mr. Dawe describes the trhrub as pubescent when young. This probably refers to the young long-shoots, of which there are none with the specimens enumerated above, and only some of the leaves of the short-shoots have still retained traces of pubescence. There is, however, a specimen at Kew, collected by Schweinfurth at Doukollo, Eretrea, which consists of young long-shoots with their leaves still attached and with very young short-shoots in the axil8 of the latter. Most of the leaves of these long-shoots are rather less obtuse than those of the short-shoots and the longest are up to 5 cm. long. They are all BOf‘tlypubescent, and have broad-triangular scarious stipules. The branches are softly pubeseent like the leaves. There are no flowers with the specimeu. The fruits accompanying it are, however, exactly like those described above. Hiern referred (1. 0.) to Randia duntetoruna also a spec’‘imen collected by Grant in the Madi Country. This very much resembles Randia niloticn, but it is vcmgueria tetruphylla, Schweinf. : Kirk’s specimens referred likewise to Randia dumetoruna belong to two species-one with large oblong fruits, persistently tomentose leaves, and very few, short spines (Tete, Lupata, Chiradzula); the other identical with R. Lachnosiphoitium, Hochst., a species 80 far recorded only from Natal. DAWEANE IN UGANDA LECTR. 521

From the material available it is impossible to say whether this is merely a sexual (female) state of Himusops ugandensis or an independent form; possibly even a distinct species. The Bugoma tree is Raid to attain a height of 24 m., and the Toro tree is described as a “large, erect tree.” This species is referred to in Dawe’s Report,’ p. 14, by a slip as Mimusops toroensis, Stapf.

THE VEOETATION OF UOAIiDA. 533

Notes on the Yeyetation of Bud& and the Western and Nile Provinces of the Uqanda Protectorate. By M. T. DAWE. TEE districts visited by me, starting from Entebbe, are :-Busiro, Mabf akota, Buddu, Koki, Ankole, Toro (including Mt. Ruwen- zori and Semliki Valley), Buyaga, Unyoro, Chiope, Acholi, Madi and Bari ; the total distance covered amounting to over 3000 miles. In the following notes I intend lo give such information concerning these districts as bears on the nature of the country, its climatic conditions, and the predominant features of the flora. My collections comprise nearly a thousand species obtained on the line of route, whilst daily on the march, no halts having been made for the express purpose of collecting. A prolonged stay in these districts Todd materially have resulted in a far more complete and representative collection.

BUSII~O,Mawa~o~a, AND BUDDU. Busiro and Mawakota lie to the north-west of the Victoria Nyanza, and Buddu lies due west. The flora of these districts, together with Chagwe, the Sesse and Buvumu Islands, shows considerable affinity with that of West Africa. The low-lying alluvial area, bordering the lake-margin of these regions down to the Anglo-German Boundary, is more or less covered with forest. Receding from the Victoria Nyanza, the country is more hilly, and is mainly composed of grass- and buuh- land j but woodland and forest is found in the valleys and low- lying localities. These areas are watered by several rivers flowing into theVictoria Nyanza. The only large aud important one, however, is the Katonga, and it is somewhat sluggish, being choked with a dense growth of papyrus and reeds. The altitude of this region averages about 4000 feet above the sea. The mean maximum temperature in the shade, as represented by Entebbe, which is situated near the lake, is 76' Fahr., the mean minimum is about 68O, and the lowest recorded teni- perature is 59". At the higher elevation of Masaka, situated on the hills about twenty miles inland from the Lake shore, the mean maximum is 75", and the mean minimum 59". The 5341 31R. 11. T. 1)AWE ON TIIE extremes registered at the latter station are 82' (March Ilth, 1904) and 55' (June loth, 1904). As affecting transpiration, it ]nay be interesting to mention, that the records of 190$ show that Entebbe has a daily average of 5 hours 55 minutes bright su~ishine. This region has no very well-defined seasons. Rain falls throughout the year ; but, as represented by Entebbe, July to October arc usdly the driest months. The average rainfall of the last four years at Eiitebbe is 55 iuches, falling on an average on 138 days in each year, usually as sudden heavy storms, which rarely last more than a few hours. The highest recorded rainfall for any one year (1904) is 63 inches. On the inlying parts of these districts the rainfall is rather lejs; but on Sesse Islands, where storms occur almost daily (usually iu the morning), it is considerably heavier. The records available indicate that it is not much less thnu 100 inches per year. During May 1904 as niang as 16.84 inches were recorded on the islands. The prominent features of the forests throughout Busiro and Mawakotii are the large trees of the following species :-Pipfa- denia africana, Pycnanthais 8chweinf tcrthii, Pseudospondias microcarpa, Parkia $licoidea, Chlorophora escelsa, Cuqtnrium Xchweinfurthii, and Antiaris tosicaria. Tn Bunjialre, which is ahnost au island, and only connected with Mawakota by swamp, the predominating tree is a species of Cynonaetra ; whilst in the northern part of the littoral forest of Budu the principal species are Piptadenia africana and Masopsis berchemoides. A little further south, Xylopfa Eminii, which is allied to a West Africau species X. atkiopica, gives a special character to the forest. Still further south, a Conifer-Podocarpus milan- jiuna Tar. arborescens-is found in this littoral belt. It is very singular that it should occur in a low-lying swampy district, at an altitude of conaiderably less than 4000 feet-a tree which usually affects hill-slopes. In the extreme south of Buddu, Zimlcsops cuneifolia and Baikaea Entinii Sire conspicuous trees ; the former has previously been recorded only from Lower Guinea. Another iuteresting feature in this locality is found in Elcyenia owariensis, which groMs gregariously in the form of small forests isolated in the swamps. Raphia dlonbuttoruna and Phmnix reclinata are common palms found throughout this forest-region. VEGKTALIION OF UGANDA. 35 From the foregoing, it will be seen that coiisiderable varin- tion is found in the formation of various parts of this littoral forest, as it stretches from a little north of the Equator to one degree south. KOKI. The divtrict known as Eoki lies to the south-west of Buddu ; it is exceedingly hilly and averages about 4500 feet altitude. Its formation is of grassland, woodlilnd being only occasionally found in the deep ravines. The average niaximuin temperature in the shade during my stay in Koki (May) was 76", and the minimum frequently fell to 55'. 111 certain 1)arts of Koki the soil is calcareous; in other parts, especially the hills, it is laterite, and schistose rocks crop up on the surface. The natives inhabit the valleys or low-lying parts of ICoki, so that an overland view from the hills gives an appearance of desolation. I am informed by the White Fathers of the ltornan Catholic Mission that the rainfall is less than that of Buddu, nhich is to be expected, seeing that it is destitute of forest. The following are conspicuous shrubs fourid in Koki :-Secu- ridaca loiigipedunculata, Parinarium curatellifolium, Euphorbia antiquorum, Pappea ugandensis, Carissa edulis, Dichrosfach?p nutans, Gardenia Thunberyin, Erythha fonteii tom, Rhus insignis, Olea chrysophylla, Acacia Gerrardi, and two species of Dombpya (D.Mukole and D. Datuei). The latter affords 8 ubeful fibre Irnown as Nhokwa; the former is a sniall tree also common in Ctragwe in the Mthira Forest. A new specie3 of Bersama, B. ugandensis, is found here ; it is a small tree, The flora of' Kolri has a slight afiiiity to the flora of South Africa. Notable examples in my collection are Acacia Cerrardi, a species from Natal and Zululand, not hitherto recordcd froin Tropical Africa ; Pnppea uyandensis, a species previously coliected by Dr. Baphan e on the AngbGerman Boundary Commission, and allied to P. capensis. ANKOLE. Ankole lies in the Western Province of Uganda, and the portion I passed through has an altitude ranging from about 4000 to 6000 feet. With the exception of the westerii parts of Ankole, the country i.i composed of rolling grass-hills arid wide expanding valleys, while the extreme Ion -lying parts are usually LINN. J0URN.-BOTABY, VOL. XXXTIL. 2Y 536 MH. N. T. DAWE ON TEE covered n itb acacia woodland. In certain central looalitiea there is a striking absence of shrubs of any description; SO scarce are they iti Rome places where I camped, that cooking had to be done with dried steiiis of P~I~J~US,found in swamps and streams. The shrubs found in Koki are also common in the shrub-land of Ankole. At the higher elevation on the hills of West Ankole the following intereding specimens are found : Lobelia Giberroa, Gnidia lanqrantha, Phillipia Stuhlnzannii, Agauria salzcifolia, Acacia Berrardi, Xchizoglossunz exinarum, Asclepias glaucophy Ilu aiid A. nzacrantha; also Paurea saligna, a small tree common in the Transvaal. The western part of Anlrole is dtsnsely wooded, and forest wvers a large area east of Lake Albert Edward. I did not spend sufficient time in this forest to gain much idea of 51 hat it contained, but collected the following trees : Parinarium excel- sum, Symphonia globullfira, Zanthoxylum s~.,a Strovnbosia, and four new species-Carapa grandlfEora, Pseudocedrela exeelsa, .Mimusops Dawei, and Gabunia odoratissinza. Both the Pseudo- cedrela and Carnpa are valuable timber trees : the latter also affords an oil. North of this forest, beyond the plateau which terminates in an escarpment about ten miies from Lake Kufuru, woodlands formed of flat-topped acacias, alternating with bushland of Euphorbia antiquoruni and Capparis fonzentosa, stretch down to the shores of the lalie. Forest is abeent from the shores of Lake Kiifuru, on both sides being a stretch o€ arid land. In the extreme north-west of Ankole the land is densely wooded, cliiefly with Albizria Brownei and Albizzia coriaria. A sinall forest is found in the Bwezu district; aiid conspicuous among the trees found there are : Phcznix reczinata, Cordia a byssinica, Cola cordifolia, Neobou fonia canescens, Pseudospondias naicrocarpa, and a new species of Pteryyotu-a handsome tree belonging to Slerculiaces. The mean niaximum temperature of Anlrole, as rtyresented bp Xlbarara (1904), Rhich is the administratibe statimt, is 77*8",tile mean miniinurn 55.6", the extreme minimum (12th Pr'oveiiiber) being 45O. This may be taken as reprebentative of the greater portion of the plateau of Ankole, which lies at about 5000 feet. In the forest-region of West Ankole the minimum was 530 www.vr1ox OF UGANDA. 537 (June). Below the platean, on the yhina near the lalie, the maximum temperature ranged from 90" to 92", and the miui:iium from 85' down to 63'.

TOItO.

This district is also in the Western PIovince, and 1it.s south of Lake Albert, exteuding down to Ankole, being bouitded on the west by the Congo Free State. It lies from about 3000 feet altitude to Mt. Huwenzori, the highest peak of which yet reached is 15,000 feet. The portion of Toro lying from 4000 to 5300 feet is physically somewhat similar to certaiii parts of Ugauda proper, where high grass and swampy streams choked with papyrus are the charac- teri-tic features. This part of Toro, as reprewited by Fort Portal, has a mean mauimiim tempersture OF 75" and a me:ui minimum of 599'. The extreiiie n)ininiuln during 1904 was 51.3". Tlie average rnirifdl is 53.14 iticlielt, falling ou a11 nverage on 134 daj R in each year. In the east-ceutral part of Toro, forest (Kibde Forest) covers an area of nearly two hundred quare miles. It extends frotii east of Fort Portal down to the northeru extremity of Ldke Ruiziirnba. Its characteristic trees are Maba abyssinica, Doli- ehandrone plnfycntyx, Purinariunz excelstr-in, E'hretia sylcatiea, Syinphoizirc globulifera, Cola cordifolici, Chrysopkjllum albidzmz, Ct-oton zainbesicus, Milletia frrratyginea ; also the following new species : Balanites Wilsonianrc, Odyendyea longipes, Ximusops ugandensis, Louoa brachysiphon, Dactylopetaluin ugundense, and Wcirburgia ugan densis. Lging to the south-west of thia forest at a lower altitude occurs another foreut, which is reniarli~blyfr' e of undergrowth and composed almost entirely of C'nometra Alexandri, an immense gregdrious tree, also found in the Semliki Valley and Unyoro. The northern exwemity of Lake Ruisimba is hid from view on the plains by several hundred a2rt)s of Typhn anyustifolia. The flat country lying west of theae fore& and the ldhe is of a low altitude, uud is studded uith Bornssus palms (B.$abellfer, vnr. ethiopica). Importaut rivers watering these plrtiiw are the Mubuku and Luitni, wliich rise in the Kuwenzori Range. 638 SIR. U. 1. DAWE 03 TEE

MT.RLJWEKZ~RI. The iuhabitauts of Mt. Ruwtsnzori Form R tribe lrnown as Bakoiijo. They do not inhabit the mountain higher than 7000 feet, but nrake, even up as I&r as the glacier, frequeut Iiuntitig excursions after the hyrax, the flesh of which they are very fund. They are remarkable euaniples of physical strength and durability. No cultivation is therefore found on the mountain higher than the habitations of these people. The bauaua does not thrive above GOO0 feet. Colocasia antiquorunt forms an important article of‘ culture for food at the higher altitude mentioned. The plants collected on the RuKenzori were obtained mainly from the Mubuku Valley, only a few additional species beiug collected on the northern flank of the uiouiitaiu, which I crcjssed on returning from the Seinliki Valley. ln the Mubuku Valley, on the lower slopes of the range, there are dense forests, in which the most conspicuous trees are S!/q~lroninglohulifera and a new species of Pseudocadrela (P. utilis), which is a valuable timber tree of enormous dimenlions. On t!re hill-forests at G000-7500 fret, one of the most striking trees is Dombeya runsorensis. Other species which form the qieciel feature of the vegetation of this altitude are : LobeZia Gibewon, Busa fhcunda (a new Rperies), Dracmza rejexa, I’hillipia h’tuhlniannii, CyatAea Dregei, h-igelia ilfoosa, Epipactie cfvicnna, and Disperis neniorosa. Another interestiug shrub found at this altitude is Gjynznosporia gracilipes, var. arguta. Froiii 8000-9000 feet bamboos (Arundinaria sp., probably A. n?pina) form a11 alniost irnpeiietrnble zoue. Within this range the following were amongst the interesting species collected : J’oducarpus ndanjianus, Cornus Volkensii, Ericinella Naiinii, Xyrsine rliododendroides, Pelitas occidentalis, Rubus Doggcttii, I

SEMLIKt VALLEY. The Semliki Valley lies between the BUMenzori Range and the Bulega and Mboga hills. It is watered by the Semliki River, that flows into the soutli end of Lake Albert. The northern part of the valley near the lake is of grassland (mostly Imperata arundinacea) j it lies at on average altitude of about 2500 feet, and has a remarkably fertile soil. Further np the river is a dense forest of majestic trees, covering the undulated Bwamba couutry j it is inhabited by forest trihes, mainly the Baamba people, and forms part of the great Congo Forest. It lies at an average altitude of nearly 3000 feet. 5iO MR. 31. T. DANE 03 THE Of the forest trees the followiiig are the most interesting species : Cynonietra Alexnndri, Kicinodendron nfricawmr, Pachy- stela Msola, Niisanga Sntiihii, Khaya anthotheca, Balanites Wilsoniana, Doliehandyone platycalyx ; and, in the higher parts of the forest nenr the Ruweiizori Range, a new apecies of Bonzhnx (B.reJEexurn> and an Irvingia. On the western side of the river the country is park-like, being pictureAquelp studded with Borassus palms, wide in the bushland Elceis guineensis (the African Oil-palm) occurs.

BUYA~A. The clistrict of Bujaga lies between Toro and Unyoro. It is separated from the former by the Musisi Xiver, and from tlie latter by the Ngusi, both of which flow into the Albert pu’janza. It forms portion of the great plateau that terminates in an escarpment of the Albert Nyailza. The portion of Buyaga I pawed through in proceeding from Toro to ITnyoro is of an undulating nature, huge granitic boulders standing out conspicuously on the hills. The greater portion iA of shrub- or bush-land. Amongst the interesting species collected here are the following :-Hymenocaidia acida, Protea madiensis, Bauhinia reticulatn, Mucuna stans, Anona senegalensis, a Cumonin, and a new species of Terntinalia (T.velas- tina), tlie bark of which is used by the natives for tanning. UNYORO. Unyoro also forms part of the Western Province. It is a large district, extending northwards from the Ngusi Biver to the Victoria Nile, that Bows into the north-eastern end of the Albert Nyanxa. It consists for the most part of a plateau that lies at au elevation of 4000 to nearly 5000 feet above the aea, and ends in the north-wed in a steep escurpment, at the foot of wliich lies, nearly 2000 feat below, the Albert Nyanza. The physical aspect of the country diflers somewhat from that of the Uganda Province. The more sharply defiiied peak- or ridge-like hilla give a peculiarity to the cuuntry, which contrasts &kingly v ith the more rounded, uiidulating ridges common to the districts near the Victoria Nyanza. The plateau region of Unyoro is reinarkably fertile and is characterized by n deep loamy soil. It coiisists chiefly of elepliaut VEQETATION OF UGANDA. 541 grassland, with dense bushland in certain parts, especially in the north. Other parts are almost park-like, studded Kith mall trees of Vitex Cienkotuskii, Erythrina fonientosa, and Cordia abyssinica. The ealltern part oE Unyoro is intersected by a number of sluggish rivers, choked with reeds and papyrus. They drain through swampy valleys into the large Kafu River, which finds its way into the Nile. The Kafu vdley is clothed with denae bush, and the river itself has wide, alinobt impassable marshea of papyrus. Of the interesting species found in the open land of Unyoro I may quote the following :-Antpelocissics Chantinii (a vine affording edible grapes), Bnuhi.ninJasso~lensis,Vernonia infundi- bularis, Senecio ruwenzoriensis (a specieA previously collected by Dr. Bagsbawe on the Anglo-German Boundary Commission), Heteromorpha arborescens, and Clerodendron cordifliunt. On the sandy plains below the rugged, rocky escarpment, the flora differs considerably from that of Unyoro generally, agree- ing with that of the low-lying laud of the Nile Province. The western part of the Uuyoro plateau is composed of dense foreats known as Budongo and Bugoma, which taken together cover an area of approsiinately 600 square miles. The character- idc trees of the Unyoro forests are :-Cynomefra Alemandri, Erythrophloeum guineense,Ricinodendron africanunt,Chlorop hora excelsa, Balanites Wilsoniana, Cassia Sieberiana, hThaya anthotheca, Celtis Soyauxii, Masopsis berchentoides, 3untumia elastica and 3.latiflia, Maba abyssinica, an Alstonia, and a Draconto- melum. The following new tree# were found in these forests :- Pseudocedrela utilis, an immense and valuable timber tree ; Cordia unyorensis, a large tree used by the natives for makiiig drums ; Balsamocitrus Dawei, a new genua in Butaceae ; Miiizu- sops ugandensis, arid Lovoa budongensis. The nortliern part of Unyoro forms a sub-district known as Cliiupe. It differs considerably iu the nature of its ciitnate alld soil; the cliiiiate is much wartiier aud the soil is poorer thall further south. The greater poriioii of Chiope is foriiied ot dellse bushland. Of the interesting species found there I illily mention the following :-Balaniies agypfiaca, Sterculia cinereu, Tamarindus indicus, Xarcocephalus Russeggeri, Stereospermunt hitnthinntrm, Strychnos Burtoni, Xcus Sycanzorus, PeucerEcrnto~~~ 542 MR.

ACKOLI. The Acholi (Shuli) country lies in the Nile Province on the north side of the Victoria E’ile. The banks of the river are clothed with a narrow strip of forest, and in the valley a few conspicuous trees are found, such as Antiaris toxicaria and Xiyelia a thiopica. The physical aspect of the eastern part of Acholi differs cou- siderably from Uiiyoro. It consists mainly of slightly undulating couiitry of bush- and grass-land. Many parts of eastern Acl~ol~ attain an altitude of over 4000 feet. The climate seems to be fairly temperate in the iieighbourhood of Fatiko, aiid it is said that fever is unknown there amongst the natives. I an1 informeil that rain falls throughout the year except during the months of December to February, but there are uo meteorological records available for this part of Acholi. The common grass found throughout Acholi (Andropyon Jilipendulus) is of a wiry nature. In marching tlirough this coutltry one mag’ traverse miles and not see a single tree The common tree found in the graaslaiid from the Victoria N11e to 3” north is Ki.qelza dhioyica, a welcome oue to the weary tra\ eller in that it affords delightful slinde. Interesting species found a few ~tiilt.~north of the Victoria Nile are :-Tetrapleura uilotica, Pseudocedrela Kotschyi, Ciutmua Adansonii, Strychnos Burtonii, Afzalia rrfricana, Cassarc gora- tensis, and Prosopis oblonga. At the higher elevation in the \icinity of Fatiko there is a strikingly large number of Terminalias that lend a special character to the landscape. They belong to three species- T,macroptera, T. Spekei, and T. Daiuei, of which the two latter are new. I? Spekei had already been cdlected by Speke iind Griint. Prom Fatiko towards Nirnule the two most striking trees are Butyrospernaunz l’arkii and Ei’cus Sycomorus. The seeds of the former are used as food by the natives, aild the sweet liuits of the latter are eaten. It may be alao interesting to uimtiun that the -4choli people domesticate bees usually iu this species of E’zcus. Their hives are loug aid of cjli~dricalform, made of VEOEThTION OF U(X.INDI. 543 bamboos or wattle. The bees have been identitied by Colonel Bingham as Apis mellifera (race Adansoni), and he informs nre that, with the exception of the fellaheen of Egypt, 110 Africa11 people, so far as he knows, have ever domesticated bees. Jatropha Curcas is sometimes used for fences round Acholi villages, and it is usual to find a plant of Jatropha Kirkii growing fenced around in the corner of a village. The latter has a huge tuberous rootstock, into which the natives thrust their spears before leaving their village on a huntiug-expedition. I failed to ascertain whether it was with a view to poisou their sprars or as an omen of good luck that this iu done. The Acholi people live mairily on grain, scorn to wear clothes, and seem to be a healthy people, except in districts where the guinea-worm is a pest. The chief food-products are : Eleusine coracann, Sesantum indicuin, Phaseolus vulgaris and P. iVungo, Cajanus indicus, and maize. They also cultivate Ceratotheca sesamoides, a plant allied to the semsem, for its seeds, which are used for food in a similar way. A Labiate-Hyptis spiciyera- is also cultivated fur its seeds, the food prepawd from which is much relished by these people.

MADIAND BARI COUNTRIES. The rest of my collection was made on the usuaI route from Nimnle to Gondokoro, the distance between these stations beiug about 107 miles. Nimule is situated on the banks of the Nile, and is a very unhealthy station, with a dismal, rocky aspect. The maximum temperature in the shade frequenlly stands at loo", while the average minimum is 65.2'. The yearly railifall is scarcely 40 inches, which falls on about 70 days in the year. Bari, as represented by Gondokoro, has an average maximum of 87.9" and au average minimum of C;7.4", the extremes are 100" and 52". The raintall average3 41.91 inches, falliirg on an average of 92 days in the year. These districts are sometimes hubject todrouglits; the hottest montbs are i\jovembt*r,December, atid January.
