Notes:—1. Var. gilletii (De Wild.) Thomas is based on a type with unusually narrow, oblong-elliptic leaves, ca. 3 times longer than broad. Specimens with such leaves are found occasionally (e.g., A. Léonard 4875), but do not appear to deserve taxonomic recognition.
2. Records of C. splendens in Burundi are errors for C. umbellatum.
