Notes.

Leandri (1939) treated Croton loucoubensis as a synonym of C. adenophorus , but his concept of C. adenophorus , as shown in his key and description, conforms to the type of C. loucoubensis as treated here. The syntype of C. loucoubensis from Mayotte is sterile and cannot definitively be placed in this species; it could also potentially belong to C. mayottae .
