Drupes 7–13 mm diam., spheroid. 2n = 20 (Costa Rica).

Malpighia glabra, native in southernmost Texas, is rarely cultivated as an ornamental shrub in Texas, but many of the plants sold under that name are actually M. emarginata. Malpighia emarginata resembles M. glabra, but its leaves are usually rounded or obtuse at the apex and often emarginate or apiculate, and some pairs of leaves are crowded in dense shoots with very short internodes, while others are separated by much longer internodes (versus all more or less evenly spaced in M. glabra).
