486 PLANTS FROM THE EEGION OF LAKE TANGANYIKA. 



Appendix I. purpureis extus pilosis, leguniine oblongo applanato piloso inter semina baud con- 

 stricto. 



Of the Tropical-African species this will have to be placed next E. parvifiorum, 

 E. Meyer ; but it is very different in leaf and calyx, and has entirely the general 

 habit of a Rhynchosia — so much so that it would be inevitably referred to that 

 genus if the seeds were not examined. 



A voluble herb, with long internodes. Branches densely clothed with short, rather 

 spreading, gray hairs. Stipules small, lanceolate, persistent. Petioles J-1 inch 

 long, spreading, densely pilose. Leaflets 3 subcoriaceous, oblong, 1-2 inches long, 

 both sides thinly pilose, the lower with its veins and veinlets raised ; the point 

 bluntish, with a minute mucro, the end one largest, distinctly stalked, the side 

 ones shorter and rather oblique. Flowers 4-8, crowded at the top of an axillary 

 peduncle which much exceeds the leaf. Pedicels very short. Calyx 2 lines deep, 

 densely clothed with short, spreading, gray hairs, the lanceolate teeth much exceed- 

 ing the tube. Corolla twice as long as the calyx, much recurved, densely silky on 

 the outside. Pod oblong, flat, h inch long, \ inch broad, densely pilose, two-seeded, 

 abruptly rounded at the base, not constricted between the seeds. Flattened funic- 

 ulus attached obliquely to the extremity of the hilura.

Remarkable in the refuse fruit, which is neither beaked (except the persisting 

 style-base) nor distinctly oblique.
