Oxalis tenella Jacq.

Slender, 2-20 cm high, the stem usually well exserted. Bulb ovoid, often 1 cm long, with soft brown papery tunics. Rhizome slender, 3-6 cm long, often enclosed in a thin tunicaceous cortex. Stem erect, usually 1-10 cm long, minutely pubescent, with 1-3 amplexicaul scales or small abortive leaves, rarely not exserted. Leaves few or many, terminally congested: petioles 1-3 cm long, pubescent, with a few glandular hairs admixed: leaflets 3, obovate, cuneate-obovate or cuneate, slightly incised at the apex, sometimes conduplicate, up to 1.2 cm long, glabrous above, pubescent beneath, minutely ciliate, the medial very shortly petiolulate. Peduncles rather numerous, as long or twice as long as the leaves, with others very short, undeveloped and producing almost sessile buds only, pubescent, with glandular hairs admixed, particularly near the apex: bracts 2, linear, alternate, on the upper part of the peduncle. Sepals lanceolate or ovate-lanceolate, 2-4 mm long, pubescent, ciliate, pale reddish, sometimes purple-streaked on the margins, ecallose. Corolla 1.1-2.4 cm long, glabrous, fugitive, white, pale rosy-violet or rarely a rich yellow, with a funnel-shaped yellow tube: laminae of the petals narrow-obovate, 3.5-7 mm broad, rotund at the apex, about as long as the narrow-cuneate claw. Filaments, the shorter 2.5-4 mm, the longer 4-6 mm long, often with short pluricellular hairs on the upper part, edentate. Ovary oblong, pubescent and callose on the upper half, the chambers 4-ovuled: styles pubescent below, with longer pluricellular hairs above. Capsule oblong, about 8 mm long, well exserted beyond the calyx. Seeds without endosperm.
