 "Inflorescence and flowers somewhat strigose or sericeous. Branchlets slender, ascending, 

 terete, striate and tuberculate, the internodes about as long as their leaves. Petioles 

 slender, 6 — 10 mm long, 2-glandular about the middle, the glands black. Blades 2,5 — 

 4 cm long, 1,5 — 3 cm broad, irregularly oval, with rounded base and obtuse or minutely 

 apiculate summit, thin, dark-green, the vGnation very slightly prominent above, the sec. 

 about 8 on a side, spreading, crooked, weak. Racemes terminal, subsessile and axillary, 

 the latter about half the length of their leaves, floriferous only near the summit. 

 Pedicels in flower about 6 mm long, elongating in fruit, slender. Galyx 4 mm broad, 

 8-glandular, the glands large, sericeous. Petals 6 mm long, the claw a third of the 

 length, spreading or slightly recurved, the limb oval, obtuse, denticulate, obscurely 

 auriculate at the truncate base. Stamens 1 0, about as long as the calyx, equal, the 

 filaments dilated downward, sparsely pilose, connate. Pistils exceeding the stamens, the 

 ovary densely white-pilose, the style tapering, the stigma small. 



A vine to 15 feet, in thicket near San Pedro plantation, 100 feet, Febr. 1921. 

 (Herbert H. Smith, Golombia n. 1532). Apparently the same collected by Burcheil, 

 near Caracas."
