The Roundleaf star creeper (Lobelia nummularia) belongs to Campanulaceae (the Bellflower family). It is a perennial herb that is widely distributed in eastern Asia, from India and Sri Lanka to China, south to Australia. It grows in moist forests and thickets, and the stems are prostrate, rooting along their length, 10-60 cm long. The leaves are ovate or circular with petioles 3-10 mm long. The flower stalks a few cm long grow from the leaf axils and produce white to light purple, plain flowers about 1 cm in diameter. The fruits are broadly elliptic or subglobose purple, 1 to 2 cm long. In Taiwanese Chinese, it is called "普剌特草".
