Description:
Species Description - Annual erect herb to 60 cm tall, usually with pseudodichotomous branching, sparsely covered with long, stellate, white hairs, especially when young. Leaf blades 4-7 x 6-8 cm, deeply 3(-5)-lobed, membranous, with a few scattered stellate hairs, especially along the veins, the base cordate or truncate; lobes elliptic to oblanceolate, with acuminate to long-acuminate apex, the margins crenate-serrate; petioles 3-8 cm long, almost glabrous; stipules 5-6 mm long, awl-shaped, with laciniate, glandular margins. Racemes simple, terminal, 5-11 cm long; flowers 5-merous, sparsely pilose. Staminate flowers distal on inflorescence; calyx ca. 1 mm long, the sepals ovate; petals to 1.5 mm long; stamens 10, white. Pistillate flowers on lower portion of inflorescence; calyx greenish, the sepals to 7 mm long, oblong, with glands along margins; petals to 7 mm long white or pinkish; ovary 3- lobed, sparsely pilose, green, the styles 3-8-branched, linear. Capsule sparsely pilose, 3-lobed to ellipsoid, 5-6 mm long. Seeds oblong, trigonous in cross section, ca. 4 mm long, warty, brown to grayish, carunculate.
Distribution and Ecology - A common herb of disturbed areas. Cruz Bay Quarter along Center Line Road (A645), Enighed (A3103), Fish Bay (A3874). Also on St. Croix, St. Thomas, and Tortola; throughout the West Indies (except Jamaica), Mexico, and Central America
