Notes.

See the note above under Croton cassinioides and its synonym C. delphinianus regarding the Scott-Elliot 1557 specimen (P00133052, upper right), which was also cited by Baillon (1891a) as a syntype of C. lasiopyrus . Croton cassinioides and C. lasiopyrus are sufficiently different that they are not easily confused; the former has smaller (1.5-6 × 0.7-3 cm) elliptic leaves with dentate to subentire margins and grows in littoral zones near sea level, while the latter has larger (4-15.5 × 2.5-7 cm) obovate leaves with entire margins and grows in moist montane forests.
