Habit and distribution.

Notes.
Baillon (1861) included material of Croton argyrodaphne (Bojer s.n.) and C. cupreolepis (Dupetit-Thouars s.n.), among the syntypes of C. chrysodaphne , which was lectotypified on a Chapelier specimen by Leandri (1972b). See Berry et al. (2011) and Berry et al. (2016b) for further discussions.
Both Croton meeusei and C. submetallicoides fit well within the variation of leaf size and shape of C. chrysodaphne , but they are reported to have the normal five petals in staminate flowers, whereas specimens from the Foulpointe area (the presumed lectotype locality as well as the epitype locality) have the unusual number of ten petals. We judge this to be somewhat of an anomaly and not a feature that has been fixed in the species overall. The type of C. meeusei lacks pistillate flowers altogether, whereas the type of C. submetallicoides has the short, curved inflorescence and pistillate flowers that are typical of C. chrysodaphne .
