Oxalis inaequalis Weintroub
LC Indigenous Endemic

Morphological description

Dwarf, stemless. Bulb ovoid, acute at the apex, about 1 cm long, with smooth brown tunics; numerous aerial bulbils are sometimes produced in the leaf axils. Leaves rosulate, often numerous (up to 70); petioles 1-2.5 cm long, minutely glandular-pilose, dilated below the articulation; leaflets 3, sessile, broadly cuneate-rotund, often about 3 mm long and 3-4 mm broad, rather succulent, with large epidermal cells, conspicuously impresso-punctate on both faces when dried, minutely glandular-puberulous above and on the margins, glabrous below. Peduncles 1-fld., up to 8 cm long, but often shorter, minutely glandular-pilose, with 2 minute alternate bracts on the upper half. Sepals oblong-lanceolate, subobtuse, glabrous or minutely glandular-pilose, 3-7 mm long, often very unequal, sometimes with 2 minute calli near the apex. Corolla 1.4-2 cm long, minutely pubescent, yellow or coppery-rose, with a rather short, widely funnel-shaped yellow tube; laminae of the petals cuneate-obovate, often slightly truncate, 2-3 times as long as the tapering claw. Filaments, minutely glandular-pilose, the longer (7-11) mm long, gibbose or scarcely toothed, the longest well exserted from the corolla tube. Ovary 2.5-3 mm long, glandular-pilose on the upper half, with elongate reddish calli near the apex, the chambers many-ovuled; styles glandular-pilose. From: Salter, TM. 1944.

Diagnostic description

Known from O. bullulata Salter by its comparatively smooth bulb tunics and longer, more exserted stamens and styles. From: Salter, TM. 1944. The genus Oxalis in South Africa: A taxonomic revision. J. S. African Bot. 1: 1-355. [CC BY]

Habitat
