K. Schumann and Pax state that S. gracilis differs from S. scaher in having quite 

 glabrous branches and corollas, less prominent nerves and broader sepals, the tips of 

 which ai*e recurved. Soyaux's siiecimen (312) from which S. gracilis was described, 

 has, however, also minutely puberulous branches and corollas. The nerves are less 

 prominent, but this is due to the leaves being quite young, and I find the sepals so 

 variable in Mann's and Barter's specimen that this difference also breaks down.
