Description:
Species Description - Subwoody twining vine to 2 m long, many-branched from base, producing scanty milky sap; stems cylindrical, striate, covered with long, stiff, yellow hairs when young, becoming glabrous at age. Leaves 7-palmately-lobed, lower leaflets once divided, chartaceous; leaflets 4-7 x 1.2-3 cm, glabrous, with deeply lobed margins and acuminate and mucronate apex, the base tapering, unequal; petioles slender, 1.5-4 cm long, hispid. Flowers solitary or a few on axillary peduncles; bracts early deciduous. Calyx green, 2-2.2 cm long, the sepals glabrous, unequal, lanceolate to rounded; corolla bell-shaped, white, with reddish center within, 3-4 cm long, the limb slightly reflexed, with rounded lobes; stamens and stigma yellow, included. Capsule conical, to 1.5 cm long, light brown, with elongate, persistent sepals at base. Seeds obtusely 3-angled, ca. 7 mm long, dull black, glabrous.
Distribution and Ecology - Occasional in open, disturbed areas. Coral Bay (A1987). Also on St. Croix, St. Thomas, and Tortola; throughout the tropics.
