Perhaps to this species should also be referred the following Uganda specimens: — 

 Ruwenzori, Scott-Mliot, 7569 ! and second day's march from Nandi, Whyte! But 

 tliey differ from the small branch of the type which 1 have seen, in being more 

 floriferous with the sepals but slightly or not at all recurved at the tips, corolla-lobes 

 2h lin. long, and the stigma more sessile. Both are very much bj-ancliedand very leafy 

 specimens 10-14 in. higli, with exceedingly numerous rather crowtled small cymes ; 

 tlie flowers are frequently 4-merous. — N. E. Br.
