Oxalis pocockiae L.Bolus

Rather weak, 5-14 cm high, the stem rarely shortly exserted. Bulb narrow-ovoid, acute at the base and apex, with 4 longitudinal wings: tunics numerous, hard, dark brown, the outer adpressed together at the margin, thus forming the wings: aerial bulbils rarely produced in the leaf-axils. Rhizome 4-10 cm long, the apical scales more or less ovate, rather large. Leaves basal or loosely imbricate on a shortly exserted stem: petioles up to 2-5 cm long, glabrous or sparsely pilose, with stipule-like membranous and often ciliate wings below the basal articulation: leaflets 3, sessile, broadly cuneate-rotund, the medial usually emarginate or slightly incised, commonly 3-6 mm long, 5-10 mm broad, the lateral smaller, oblique, entire, rarely sparsely ciliate, thick, impresso-punctate on both faces when dried, often purple beneath, sometimes with 2 or more small black calli near the anterior margin. Peduncles 1-fld., longer than the leaves, with 2 alternate bracts above the middle. Sepals oblong-lanceolate, obtuse, 4.5-7 mm long, sometimes penicillate at the apex, rarely ciliate, usually more or less purple, particularly on the margins, bicallose at the apex. Corolla 1.2-4 cm long, rose or white, with a funnel-shaped yellow tube: petals broadly and obliquely oblanceolate, often acute at the apex, the claw slightly attenuate. Filaments minutely glandular-pilose, the longer edentate. Ovary glabrous or pubescent at the apex, rarely callose, the chambers 9-10 ovuled: styles pubescent. Seeds endospermous. Occasionally produces double flowers.
