Thave not succeeded in discovering any tangible difference between the type 
of 8. manniana and the plant described by Engler as S. Zenkeri. Engler says 
that his plant is more hairy and has larger leaves and stipules than in S. man- 
mana, but no such differences are evident in the Kew specimens. 
Engler figures the filaments of S. Zenkeri as being papillose, but he does not 
mention the fact in his description ; in the type number at Kew they are 
quite glabrous.
