Botanical Description

Hedyotis diffusa (syn. Oldenlandia diffusa), snake-needle grass, is a slender annual herb of the family Rubiaceae native to moist grasslands, ditches, rice-paddy margins and waste ground throughout southern China, Southeast Asia, Japan and Korea. It produces a slender taproot and many prostrate to ascending, quadrangular, glabrous stems 15-50 cm long that branch repeatedly from the base. The opposite, sessile, linear to narrowly lanceolate leaves are 1-3.5 cm long and only 1-3 mm wide, with revolute margins and a single midvein, subtended by small membranous stipules. Tiny solitary or paired axillary flowers about 2 mm long have a four-toothed calyx and a four-lobed white tubular corolla, followed by small flattened-globose capsules 2-3 mm across crowned by the persistent calyx and containing numerous angular seeds. The whole flowering herb with root is harvested in summer.
