__NOTOC__
:Protologue: Gard. Bull. Sing. 21: 200 (1965).
== Synonyms ==
''Fleurya aestuans'' (L.) Gaudich. (1830)
== Vernacular names ==
*Papua New Guinea: maribean (Kurtatchi, Bougainville Island).
== Distribution ==
From tropical America, the West Indies, tropical Africa, Madagascar, Arabia, India to Sumatra, Java and the Lesser Sunda Islands, possibly extending to New Guinea.
== Uses ==
In Bougainville Island (Papua New Guinea), the root and stem bark are externally applied to sores on the sole of the feet. In Trinidad, Brazil and Peru, a decoction of the plant is taken as a diuretic.
== Observations ==
A monoecious, annual herb up to 1(-)2 m tall, stem fleshy, slightly woody at base, with few branches, glabrescent to densely armed with short irritant hairs and long glandular hairs; leaves ovate to broadly ovate, (3-)10-15(-30) cm × (2-)8-12(-21) cm, base rounded to cordate, apex acuminate, margin dentate, with scattered irritant hairs on the upper surface, petiole (2-)5-15(-20) cm long, densely covered with irritant and long glandular hairs, stipules up to 1 cm long, with few short irritant hairs; panicle bisexual, well-branched, usually solitary, up to 20 cm × 10 cm, bracteolate, male flowers pedicellate, about 1.5 mm long, with few glandular hairs and very few irritant hairs, filaments reflexed, interfloral bracts very numerous, female flowers pedicellate, pedicel slightly winged dorsi-ventrally, glabrescent, stigma linear, unbranched, about 0.3 mm long, interfloral bracts minute, numerous; achene asymmetrically ovoid, stipitate, 1-2 mm × 1-2 mm, partly surrounded by a narrow membranaceous wing, on each lateral side a triangular ridge enclosing a warty depression, perianth reflexed, pedicel often winged dorsi-ventrally; achene dispersed with perianth and upper portion of pedicel attached. ''L. aestuans'' is common in disturbed semi-shaded habitats, along roads in abandoned gardens, plantations and shoreline vegetation dominated by ''Pisonia grandis'' R.Br.
