Copyright CSIRO +/- erect, glabrous, about 4-12 cm long, pedicels about 2-3 mm long at anthesis, subsequently elongating. Tepals about 2-2.5 mm long, glabrous. Anthers glabrous. Ovary subglobose, glabrous, style short with an extension running down the side of the ovary. Fruit Fruits bright red, about 3.5-4 mm diam. Testa brown, surface hairy. Embryo horseshoe-shaped, surrounding a central pocket of endosperm, cotyledons rolled longitudinally like a cigar. Seedlings Cotyledons orbicular to almost cordate, glabrous, about 9-11 mm diam, petiole about 8-10 mm long, almost as long as the cotyledon. At the tenth leaf stage: leaf blade lanceolate or broadly lanceolate, petiole almost Scale bar 10mm. Copyright CSIRO as long as the leaf blades. Upper surface of the petiole, near its junction with the leaf blade, densely clothed in short, glandular (?) hairs. Petiole grooved on the upper surface. Distribution and Ecology An introduced species originally from tropical America, now naturalised in CYP (Torres Strait Islands), NEQ, CEQ and southwards as far as coastal central New South Wales. Altitudinal range from near sea level to 900 m. Usually a weed associated with man-made or modified vegetation types but also grows in disturbed areas in lowland and upland rain and monsoon forest. Also found in closed vegetation types near the sea. Also occurs as a pantropic weed.
