K. Schumann and Pax state that S. gracilis differsfrom S. scaber in having quite 
glabrous branches and corollas, less prominent nerves and broader sepals, the tips of 
which are recurved. Soyaux’s specimen (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 80 
variable in Mann’s and Barter’s specimen that this difference also breaks down.
