338 ASCLEPIADAOE.E ELLIOTIAN^.. 



Kampala, shady places, Jan., No. 7294. 



This determination is a little doubtful, as I have not seen Schu- 

 mann's type, but the description agrees well enough, as far as it goes. 



Sarcostemma E. Br. 

 There are two numbers evidently belonging to this section, but 

 both without any flowers, and therefore undeterminable. (No. 7267 

 from Usoga, and No. 7341 from Kampala, Uganda.)

bbire, Zambesi, at Chiromo, Jan., No. 3791. 



A most distinct new species, which, from its appearance, would 

 rather suggest Penjularia as tlie generic name than Marsdenia, but 

 certainly belonging to tbe latter. From the few African species of 

 the genus it is very distinct by the size and shape of the flowers, 

 and may be nearest allied to the Abyssinian Marsdenia Schimpcri 

 Hochst., but from this it differs by the corona. Of other Marsdenias 

 it resembles somewhat the American M. Prinylei Wats, and M. 

 wiihellata Griseb. ^[. zambesiaca is the southernmost species of 

 the genus in Africa. The flowers appear to have been green in the 

 living state, but turn brownish in drying. 



Tylophora R. Br. 



Tylophora longipedunculata Schltr. S/iharocodon longipeduncu- 

 latum K. Sch. in EnqL Flor. Ost-Afr. 32G. 



Ruwenzori, Butagu Forest, 8000 ft., No. 7973. 



Sj)ha;rocodon longipeduncidatum K. Sch. should, I consider, be 

 placed in the genus Tylophora, of which it has the climbing habit, 

 and exactly the same coronal structure. The genus Sphcerocodon 

 is, I confess, very nearly allied to Tylophora, and may, when we
