Discussion

Genera 18, species ca. 530 (2 genera, 2 species in the flora).

Chrysobalanaceae was traditionally considered a subfamily of the Rosaceae. Family status is supported by morphology (G. T. Prance 1972; Prance and C. A. Sothers 2003) and molecular data, which place it as a member of the Malpighiales and thus not closely related to the Rosaceae (see, for example, M. W. Chase et al. 1993; N. Korotkova et al. 2009; K. Wurdack and C. C. Davis 2009). Only Chrysobalanus icaco is important commercially; it is planted as an ornamental and its fruits are eaten raw or bottled in syrup and sold (A. Cronquist 1981).
