Notes.

Radcliffe-Smith (2016) noted that Croton leandrii and C. chlaenacicomes are very similar, and in fact there is no reason to keep them separate. Some specimens that were identified under these names in the past, but with pubescence on the upper surface of the leaves as well as below, are now treated under C. toliarensis B.W. vanEe & Kainul.
