*''Convolvulus umbellatus'' L. (1753).

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.

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.
