Protologue: Prodr. 4: 424 (1830).

• Hedyotis brachypoda (DC.) Sivar. & Biju (1990),
• Hedyotis diffusa auct. non Willd.,
• Oldenlandia diffusa auct. non (Willd.) Roxb.

• Malaysia: bunga chakar ayam, rumput angga (Peninsular)
• Philippines: ulasiman-kalat (Tagalog), daniri (Bisaya)
• Thailand: hom chaeo naa (Khon Kaen).

From Sri Lanka, India, southern China and Japan to Malesia; also in tropical America.

In Malaysia, the plant is used for poulticing, apparently against lumbago. In India, a decoction of the whole plant is used to treat biliousness, fever and gonorrhoea.

• A prostrate annual herb up to 45 cm long, usually branched from the base, branches terete.
• Leaves linear-lanceolate, up to 4 cm long.
• Flowers axillary, solitary, sometimes 2-3 together, corolla white to purplish.
• Fruit subglobose.
• Seeds reticulate.

O. brachypoda usually occurs in humid or swampy locations such as rice fields and along streams, up to 1100(-1500) m altitude. It has been very often confused with O. diffusa (Willd.) Roxb., which is also a common weed, and which possibly has comparable uses and properties.
