Description:
Species Description - Trees 4-15 m tall; stems persistently sericeous, the older woody stems glabrate. Lamina of the larger leaves (10-) 13-18 cm long, (5-)7-9.5 cm wide, elliptical, cuneate or truncate at the base, abruptly acuminate at the apex, bearing 2 large glands near the base and sometimes several small submarginal glands near the apex, glabrate above, densely and persistently silvery- or golden-sericeous below, completely covered by the short, straight, sessile hairs; petiole (7-)9-13 mm long, sericeous, eglandular; stipules ca 0.5 mm long, borne on the base ofthe petiole. Inflorescence 7-11 cm long, without vegetative leaves, sericeous, the 15-35(-50) flowers proximally decussate, distally mostly in no regular order; bracts 1-2.5 mm long, triangular; peduncle 1-3 mm long (-5 mm in fruit); bracteoles apical, 1 mm long, 1 or both bearing an abaxial gland or subtended by a gland on the peduncle. Pedicel 3-7 mm long, loosely sericeous. Sepals 1-1.5 mm long beyond the glands, 1-1.5 mm wide, rounded, ciliate on the margin and otherwise glabrous, the glands 8-9, 2-3.5 mm long. Petals yellow, eglandular or the posterior and some laterals glandular-dentate proximally. Filaments 2-2.5 mm long, ca 1/3 connate; anthers 1-1.5 mm long, the connective brown to red, glandular, broad and flat, the locules somewhat pendulous at base. Ovary 1.5 mm high, ovoid, bicarpellate, very densely sericeous; styles 2, free, 1.5 mm long, glabrous except at very base, the stigmas capitate. Fruit 15-25 mm long, 15-20 mm in diameter, ovoid, orange to red-orange, ± persistently sericeous.

Discussion:
2. Bunchosia argentea (Jacquin) de Candolle, Prodr. 1: 582. 1824. Malpighia argentea Jacquin, Fragm. Bot. 186, tab. 83. 1800-1809. Type. Jacquin, Caracas, Venezuela. It is surprising to find this northern species in Bolívar, but I have no reason to doubt the identification, except that the petals of the Guayana collection were glandular-dentate, versus eglandular in the northern collections. The description given above is based on the collection cited, plus others from northern Venezuela. Steyermark and Gibson described their plant as "vining," but it is more likely to have been a tree.
