Oxalis ambigua Jacq.

Stemless or the stem sometimes shortly exserted, usually 4-12 cm high, more or less finely pubescent, more rarely with some glandular hairs admixed or almost all the hairs glandular. Bulb ovoid, acute at the base and apex, often 2-4 cm long, with hardish dark brown gummy tunics. Stem scarcely exserted or more often 1-2 cm long or longer, robust, fleshy, leafless, with a few semiamplexicaul scales. Leaves 15-30, clustered at the apex of the stem, with petioles 2-6 cm long; leaflets 3, often emarginate, pubescent on both sides, ciliate with simple or rarely glandular hairs, rarely purple-mottled, sprinkled on the underside with numerous small blackish dots (sometimes with translucent red centres), the medial shortly petiolulate, cuneate-rotund, cuneate-obovate or cuneate-oblong, often tapering attenuately to the base, 0.5-2.5 cm long, 0.5-1.1 cm broad, or rarely oblong, 4-7 times as long as broad, the lateral subsessile, oblique, usually rather smaller. Peduncles 1-fld., shorter or longer than the leaves, with 2 small opposite bracts at an articulation above the middle. Sepals lanceolate, 4-5 mm. long, ciliate, minutely bicallose at the apex. Corolla 1.8-2.8 cm long, white, yellow or cream-coloured, with a rather widely funnel-shaped yellow tube; laminae of the petals broadly cuneate-obovate, purple-striate towards the outer margin, rather longer than the tapering claw. Filaments, the shorter 2.5-4.5 mm, the longer 4-7.5 mm long, glabrous or minutely glandular-pilose, with rather long subacute teeth. Ovary pubescent on the upper part, with numerous orange-red calli reaching nearly to the base, the chambers about 9-ovuled; styles pubescent below, glandular-pilose above. Capsule not exserted. Seeds endospermous.
