Oxalis fibrosa F.Bolus

Stemless, up to 7 cm high, or larger in shade forms, clothed with viscous pluricellular hairs. Bulb narrow-ovoid or the younger lanceolate in outline, with a long slender tapering curved beak; tunics black or dark brown, smooth, needle-pointed, the older often imbricating on the rhizome through the action of the contractile root. Rhizomes glandular-pilose on the upper part, the old dead ones persisting and numerous, at times forming a somewhat fibrous mass. Leaves 7-35, basal or in shade forms imbricating on a very short stem; petioles up to 2.5 cm long; leaflets 3, the medial shortly petiolulate, cuneate-obovate, 5-6 mm long and broad, the lateral sessile, oblique, sparsely pluricellular-pilose on both faces, ciliate with pluricellular, capitate or long simple hairs. Peduncles 1-3 cm long, ebracteate or with one or two minute bracts below the middle. Sepals ovate-lanceolate, acute, 3-4 mm long, ciliate, ecallose, usually more or less purple-margined. Corolla 2-3.5 cm long, glandular-pilose, pale lilac, with a subcylindrical yellow tube; petals very thin and fugitive, the laminae obliquely narrow-obovate, as long as the claw, rarely dotted with purple calli on the outer margin. Filaments, the shorter 5.5-8 mm, spreading, the longer 7-11 mm long, sparsely glandular-pilose on the lower half, shortly toothed near the base, spreading in the longistylar form; anthers subsagittate. Ovary shortly glandular-pilose on the upper half, the chambers 1-2-ovuled; styles pubescent below, glabrous above, spreading except in the longistylar form. Seeds without endosperm.
