Native to tropical America; introduced into Java (Indonesia).


S. glabra was considered a promising fibre plant for Indonesia, but experimentation was interrupted, and was not resumed. It was formerly cultivated as a fibre plant on Caribbean Islands.

Leaves simple, alternate; stipules linear, about 1 cm long; petiole 3-6 cm long; blade widely ovate to oblong, upper ones lanceolate, 1-10 cm × 0.5-6 cm, base cordate, apex acuminate, penninerved, 7-9-veined. Flowers axillary, solitary, by decrescence of upper leaves appearing as a branched, lax panicle; pedicel thin, jointed, 7-15 mm long, increasing up to about 20 cm in fruit; calyx widely campanulate, 4-5 mm long, 3-4 mm in diameter, 5-lobed; corolla 8 mm in diameter with 5 deeply emarginate petals, yellow. Fruit a pyramidal schizocarp, 3-3.5 mm in diameter; mericarps 5. Seed oblong to reniform, about 1.5 mm in diameter, brown-black. S. glabra is found in waste places and along roadsides up to about 300 m altitude.
