Oxalis uliginosa Schltr.

6-16 cm high, sparsely clothed with short pluricellular viscous hairs or almost glabrous, the stem usually not exserted. Bulb ovoid, attenuate-acute at the apex, about 1-6 cm long, with somewhat wrinkled acutely pointed brown scales. Rhizome 8-24 cm long, with small scales. Leaves 10-25, imbricately clustered at the base: petioles 2-0.12 cm long, sparsely viscoso-pilose, with no perceptible basal articulation, the dilated scale-like base sometimes 1 cm long: leaflets 3, shortly petiolulate, broadly cuneate-obcordate, sometimes slightly attenuate at the base, not very deeply incised, 0-6-2 cm long and broad, thin, glabrous or sparsely pilose, beneath, ciliate, dotted with numerous reddish-brown calli, especially near the margin.. Peduncles, 1-fld., rather longer than the leaves, glabrous or viscoso-pilose, especially towards the apex, with 2 alternate subulate callose bracts on the upper half. Sepals 4-5 mm long, narrowly obovate-oblong, very obtuse, with numerous conspicuous orange-brown calli on the upper 2/3. Corolla 1.6-2.8 cm long, yellow, with a rather broad funnel-shaped tube: laminae of the petals widely and obliquely obovate, subtruncate, about twice as long as the attenuate claw. Filaments, the shorter 2.5-4.5 mm, the longer 4.5-8 mm long, with pluricellular hairs and rather short thick projecting teeth. Ovary glandular-pilose on the upper half, copiously sprinkled with reddish calli, the chambers 2-ovuled: styles pluricellular-pilose. Capsule globose. Seeds without endosperm.
