Enumeration of Plants collected by V. Lovett Camebon, Jjieut. 

 R.N., in the region about Lake Tanganyika. By D. Oxivee, 

 F.R.S. &L,S., Keeper of the Herbarium, Hoyal Gardens, Kew. 



[Read November 4, 1875.] 



[The following notes comprise" an enumeration of the species 

 contained in a small parcel of plants received at Kew in February 

 1875, and which had been collected by Lieut. Cameron south of 

 Kawele (lat. 4° 58' 3" S., long. 30° 4' 30" E.), in his journey round 

 the shores of Lake Tanganyika in search of the outlet which he 



Lieut. Cameron 



believes this to flow into the Lualaba, which he all but positively 

 identifies with the Congo f. The flora of the region round the 

 lake, on this supposition, belongs to the Congo river-basin. The 

 enumeration has been drawn up by Prof. Oliver ; the descriptions 

 of new species are by himself and by Messrs. Baker and Spencer 

 Moore, assistants in the herbarium.]
