All authors have mistakenly referred C. penicellatus A. Rich. to a variety of C. sagittatus presumably because they did not see the type specimen. This specimen and also the original description leave no doubt as to the identity of Richard’s species. The type of C. schweinfurthii has triangular-hastate leaves with concave sides whereas the Linnean type of C. farinosus has more regularly ovate leaves with convex denticulate margins. These two forms are joined by intermediates, e.g. Orde Brown (from Mt. Kenya, Feb. 1914).
