Oxalis exserta T.M.Salter

Erect, caulescent, densely pubescent, 4-10 cm high. Bulb narrow-ovoid often 2 cm long, with rather thin brown tunics. Rhizome 4-7 cm long, with several lateral underground scale-bearing runners or stolons up to 20 cm long, producing bulbils at their apices. Stem 1-7 cm long, sometimes bearing 1-2 subsessile cauline leaves. Leaves fairly numerous, apically congested, with slender petioles 0.5-1.5 cm long; leaflets 3, linear or oblong, emarginate, subconduplicate, 0.6-1 cm long, often glaucous, ciliate, ecallose, pubescent on both faces. Peduncles few, 1-fld., as long as or little longer than the leaves, with 2 subulate bracts imbricating the calyx. Sepals broadly lanceolate, subacute, 4.5-5 mm long, ecallose. Corolla rose, 1.7-2.2 cm long, with an obscurely yellow cylindrical pubescent tube; laminae of the petals obovate or narrow-obovate, as long as the narrow claw. Filaments, the shorter 5-8 mm, the longer 8-13 mm long, sparsely glandular-pilose, the longest unequal, well exserted from the corolla tube. Ovary densely pubescent, the chambers 2-ovuled; styles glandular-pilose, the longest exserted. Sometimes produces double flowers.
