7,000 feet. A 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 6,000 feet include some 

 widely distributed tropical species, such as Vigna 

 luteola, Ageratmn conyzoides, and other composites, 

 with a new variety oiLaggera alata, a common Tropical 

 African and Asiatic species ; some widely spread 

 Tropical African species, such as Desmodmm Scalpe 

 (also India), Melanthera Brownei (also South Africa), 

 Platystoma africanuni (also India), Cyathida cylindrica 

 (also South Africa and Madagascar), and Crimtm 

 giganteum. A marked east tropical affinity is shown 

 by Eriosema montanum, Osbeckia densiflora (Mozam- 

 bique), Helichrysum fcetidum, and Indigofera longebar- 

 bata (Abyssinia) ; BrUlantaisia patula is a Cameroons 

 plant, also found in Uganda. Isoglossa rtmssorica, 

 Trimnfetta ruwcnzoriensis, and Gyniira ruwenzoriensts, 

 the two latter also collected at 7,000 feet, represent 

 an endemic distribution ; and the following are 

 novelties : Thimbergia oculata., Coleus gracilentus, and 

 Pentas pubiflora. 



6,000 to 7,000 feet : The banana is not cultivated much 

 above 6,000 feet, and the 'elephant-grass' ceases at 

 the same level. Above this is a zone of shrubs, 

 conspicuous among them being Acanthus arboreus 

 with mauve flowers, two or three yellow-flowered 

 papilionaceae, and a handsome Solamim 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 7,000 feet and beyond. Dracaenas, reaching a 

 height of 30 feet and upwards, are found in groups 

 beside the streams. Millet and colocasia are culti- 

 vated up to 7,000 feet, above which level cultivation 

 ceases.
