Notes.

Croton chapelieri   was accepted by Leandri (1939) but was restricted to the type specimen, due at least in part to the meager type specimen and the lack of any reported collection locality. Similarly, C. aymoniniorum   has been recognized only from the type collection. Extensive collections and our own field studies from coastal areas of southeastern Toliara Province (Mandena, Petriky, and Sainte Luce) show that both of these type specimens correspond to a locally common species found in sandy, littoral forests to the west and north of Fort Dauphin, in the Mahabo area of Fianarantosa Province, and then in Toamasina Province much farther north. Chapelier collected mainly in the Foulpointe and Tamatave area ( Dorr 1997), and his specimen is similar to the type of C. louvelii   , from a nearby area. Many herbarium specimens of this species were identified by the late Alan Radcliffe-Smith and subsequent botanists as Croton daphniphyllus   Radcl.-Sm., or sometimes as Croton rhododendroides   Radcl.-Sm. for a more pubescent form. See Kainulainen et al. (2017a) for more details about the circumscription of C. chapelieri   . Newly added to the synonymy here are C. domohineifolius   Radcl.-Sm. and C. macrobuxus var. polygynus   Radcl.-Sm., both from littoral sites on the east coast where C. chapelieri   is one of the few species to occur.
