230 DR. А. B. RENDLE ОХ PLANTS 
fasciculata, а Cameroons plant, and Mucuna Родде (found at 4000 ft.). 
Schizoglossum eximium is restricted to Ruwenzori; and the following are new 
species: Aloe Wollastoni, Chlorophytum ruwenzoriensis, and Baphia Wollastoni 
(at 4000 ft.), allied to the West African B. angolensis. 
4000-5000 feet. About this level there 13 а good deal of native cultivation, 
chiefly bananas, manioc, indian corn and beans. At this altitude the huge 
* elephant-grass " growing from 10 to 15 feet high is the most important 
feature of the vegetation, and conspicuous among it are the pretty little trees 
of Erythrina tomentosa with tufts of crimson flowers. 
The following were collected at 5000 ft. :— Tephrosia paniculata (Angola 
and Uganda); Mlewrya podocarpa, a widely spread tropical African species; 
Crinum scabrum, а more northern type (Abyssinia and the Nile Valley); and a 
new composite, Guizotia collina. 
5000-6000 feet. Cultivation and elephant-grass still continue, with species 
of Ipomea climbing about the stems of the grass, and the very handsome 
red-and-yellow Gloriosa virescens (var. splendens, var. nov.), which is found 
up to 7000 ft. А few small patches of forest with a good many ferns, 
polypodiums and others fill the bottom of the valley at this level. 
The plants collected at 6000 ft. include some widely distributed tropical 
species, such as Vigna luteola, Psophocarpus palustris, Ageratum conyzoides and 
other composites, with a new variety of Laggera alata, a common tropical African 
and Asiatie species ; some widely spread tropical African species, such as 
Desmodium Scalpe (also India), Pentas purpurea, Melanthera Brownei (also 
South Africa), Platystoma africanum (also India), Cyathula cylindrica (also 
S. Africa and Madagascar), and Crinum giganteum. A marked east. tropical 
affinity is shown by Eriosema montanum, Rhamphicarpa Herzfeldiana, Osbeckia 
densiflora (Mozambique), Helichrysum fotidum, Sonchus Bipontini var., and 
Indigofera longebarbata (Abyssinia) ; Brillantaisia patula is а Cameroons 
plant also found in Uganda. Streptocarpus ruwenzoriensis (also in Usambara), 
Isoglossa runssorica, Triumfetta ruwenzoriensis and Gynura ruwenzoriensis, the 
two latter also collected at 7000 ft., represent an endemic distribution; and the 
following are novelties: Thunbergia oculata, Coleus gracilentus, and Pentas 
pubiflora ; a variety of the last occurs at 7000 ft. 
6000-7000 feet. The banana is not cultivated much above 6000 ft. and the 
elephant-grass ceases at the same level. Above this is a zone of shrubs, con- 
spicuous amongst them being Acanthus arboreus with mauve flowers, two or 
three yellow-flowered РарШюопасеж and a handsome Solanum with prickly 
leaves and a large yellow fruit. The first of the tree-lobelias (L. Giberroa) is 
found in the open places on sunny slopes. Wild bananas are found in shady 
places up to 7000 feet and beyond. Dracænas, reaching а height of thirty 
feet and upwards, are found in groups beside the streams. Millet and colo- 
casia are cultivated up to 7000 ft., above which level cultivation ceases. A 
large number of species was collected at 7000 ft., the majority of which are
