List of species

Sida javensis Cav.

Protologue: Diss. 1: 10, t. 1, f. 5 (1785).

Family: Malvaceae

Vernacular names

Philippines: igat-igat, marmaraipus (Iloko), hapunang-niknik (Tagalog)
Vietnam: bái java.

Distribution

India and South-East Asia; in Malesia, it is common in Java, Peninsular Malaysia, the Moluccas and the Philippines.

Uses

A decoction of the entire plant is used specifically against gonorrhoea.

Observations

A prostrate herb, branched at base, with stems rooting at the nodes, more or less hairy.
Leaves orbicular-ovate, 0.5-6 cm long, entire or trilobed, base cordate, apex pointed, margins crenate-serrate, palmiveined, petiole 0.5-6 cm long, stipules equal.
Flowers normally solitary, pedicel 10-25 mm long, petals obovate, emarginate, 7 mm long, yellow.
Mericarps 5, tetrahedral with rounded angles, 3-5 mm long, awns 2, 1-2 mm long, slender, short hairy.

S. javensis grows along roadsides, in teak forests, secondary growths, forest edges, from sea-level up to 1500 m altitude, mainly restricted to areas with a dry season. Two subspecies are distinguished: subsp. javensis , with usually trilobed, pointed leaves, pedicel 20-25 mm long, accrescent to 35 mm, calyx 6-7 mm in diameter, stems sparsely stellate-hairy, and subsp. expilosa Borss. Waalk., with entire, obtuse leaves, pedicel 7-15 mm long, accrescent to 20 mm, calyx 4 mm in diameter, and densely hairy stems and petioles. The 2 subspecies have a similar ecology and distribution.
