<big>''[[Merremia umbellata]]'' (L.) Hallier f. subsp. ''orientalis'' (Hallier f.) Ooststr.</big>
__NOTOC__
:Protologue: Fl. Males. ser. I, 4: 449 (1953).
== Synonyms ==
''Convolvulus umbellatus'' L. (1753).
== Vernacular names ==
*Indonesia: lawatan kebo (Javanese), areuj geureung (Sundanese), daun bisul (Moluccas)
*Malaysia: andur nasi (Peninsular), ulan tapak pelandok
*Philippines: kalamitmit (Tagbanua), bangbangau (Iloko), kamokamotihan (Tagalog)
*Thailand: chingcho khaao (northern), thao dok baan tuum (south-eastern), en (peninsular)
*Vietnam: bìm tán.
== Distribution ==
''M. umbellata'' subsp. ''orientalis'' occurs from tropical East Africa, Seychelles, India, Sri Lanka eastwards to China, Indo-China, Thailand, and southwards through Malesia to northern Australia. Subsp. ''umbellata'' occurs in America from Mexico to Paraguay, in the West Indies and in tropical West Africa.
== Uses ==
In Peninsular Malaysia and the Moluccas, pounded leaves are used to poultice burns, sores and scalds. In Indonesia, a poultice of the leaves, together with Curcuma powder ( ''Curcuma longa'' L.) is applied on cracks in the soles of the feet. The seeds yield a mucilage used as an aperient and alterative in cutaneous diseases. In Indo-China, the latex of the root is taken as a purgative. In the Philippines, a decoction of the roots is drunk as a remedy for haematuria.
== Observations ==
An annual twiner, 1-3 m long, sometimes prostrate, terete, softly pubescent or glabrescent, young parts with milky juice; leaves ovate to oblong, 4-12(-16) cm × 1-6.5(-9) cm, base cordate, rounded or truncate, basal lobes rounded or angular, apex acuminate, both sides sparsely to densely hairy, petiole 1.5-6 cm long; cymes few- to many-flowered, umbelliform, peduncle 1-4(-7) cm long, bracts minute, caducous; flower-buds ovoid, pedicel 5-9 mm long, sepals subequal, concave, broadly elliptical or orbicular, 5-7 mm long, corolla funnel-shaped, 2-3 cm long, white, rarely yellow to orange, middle part mid-petaline bands hairy, anthers straight; capsule ovoid to conical, 10-12 mm high, mucronate by style-base, glabrous or sparsely hairy at top; seeds 5 mm long, densely hairy with soft, patent hairs. ''M. umbellata'' occurs in thickets, along edges of forests, in plantations, in grasslands, along fields and roadsides, from sea-level up to 1100 m altitude. Subsp. ''umbellata'' (synonym var. ''occidentalis'' Hallier f.) differs from subsp. ''orientalis'' in its more robust habit, with larger leaves, longer peduncles, more and larger yellow flowers, a subglobose capsule, with broader, ovate valves, and seeds shorter pubescent.
