Oxalis convexula Jacq.

Erect, rather succulent, 4-14 cm high, entirely glabrous, usually with a well-developed and sometimes branched stem. Bulb narrow-ovoid, attenuate or subrostrate at the apex, 2-3 cm long, the older often persisting on the rhizome through the action of the contractile root; tunics imbricating, rather thin, rough, reddish-brown. Stem thick, 2-5 cm long or rarely not exserted. Leaves often numerous, short and closely congested or spreading, up to 5 cm long; petioles dilated into prominent submembranaceous stipuliform wings below the articulation; leaflets 3, thick, fleshy, entire, the medial shortly petiolulate, subrotund, widely attenuate at the base, 4-10 mm long, 5-12 mm broad, the lateral obliquely rotund or sub-semicircular, rather smaller, conspicuously impresso-punctate on both sides (very irregularly on the scurfy lower surface) when dry. Peduncles 1-fld., 1-5 cm long, usually longer than the leaves, with 2 alternate linear or oblanceolate membranous bracts towards the calyx. Sepals ovate or oblong-ovate, obtuse, submembranaceous, 3-5.5 mm long, ecallose. Corolla 1.6-2.6 cm long, pale salmon-rose, with a short widely funnel-shaped yellow tube; laminae of the petals broadly and obliquely cuneate or subtriangular, obliquely truncate, twice or three times as long as the attenuate claw. Filaments, the shorter 2.5-4 mm, the longer 4-8.5 mm long, minutely glandular, edentate, the longest exserted from the corolla tube. Ovary oblong, sometimes minutely glandular-pilose on the upper half, ecallose, the chambers about 18-ovuled; styles sparsely and minutely glandular-pilose.

It is a subtropical plant.

The root is eaten as a snack and a vegetable. The leaves and flowers are used to make a drink.
