Oxalis ericifolia Oberl. & Dreyer

Slender, stemless geophyte, 40-70 mm tall, clump-forming, variously covered with hyaline pluricellular hairs, glabrescent with age. Bulbs aggregated into complex system of old rhizomes, sheaths, adventitious roots and developing bulbs; with new years’ growth penetrating through remains of previous years; individual bulbs lanceolate to obovate, flattened due to growth in between layers of substrate, 10-20 mm long, tunics papery, dark brown to black, glabrous. Rhizome 45-160 mm long or longer, white to orange, succulent, often very thick, densely glandular pubescent towards apex, glabrescent towards bulb, densely enclosed in fibrous mass of old tunics and bulb remains, leaf bases on upper rhizome imbricated by 3-5 scales, scales sparsely ciliate. Above-ground stem absent. Leaves apically congested at tip of rhizome, 3-17 per plant, erect, all of similar height; petiole 15-30 mm long, filiform, up to 0.4 mm in diameter, rigid, wiry, red, leaves densely glandular hairy when young, becoming less so with age; leaflets 3, palmate, erect, rigid, sessile to very shortly petiolulate, involute, shortly glandular-pubescent when young, glabrescent with age, 15-28 x 2.0-2.5 mm, apex rounded to slightly emarginate, adaxial epidermis beset with cylindrical, translucent papillae. Peduncle 1-flowered, 35-55 mm long, slightly thicker than petioles, swollen apically, basal articulation massively swollen, almost gall-like in appearance, glabrescent with age, shiny. Sepals narrowly triangular to lanceolate, 2.0-3.0 x 1.0-1.5 mm, acute, wine red, glabrescent with glandular hairs along margins; bracts 2, filiform, alternate, variable in position but mostly in middle or upper part, sometimes appressed to calyx, wine red, glabrous. Corolla campanulate, white with base of petals wine red, floral tube absent; petals oblanceolate, minutely clawed, 12-16 mm long, apex truncate or rounded, occasionally subacute, ecallose. Stamens in 3 series, 2 series per plant, shortest 2.0-3.0 mm long, middle 4.0-5.0 mm long and longest 6.0-7.0 mm long, basally adnate; anthers oblong, yellow; filaments wine red, covered with red glandular hairs; filament teeth oblong to spathulate, adnate to longer filaments, obtuse, glabrous; pollen bright yellow. Ovary narrowly ovoid, 1.2-1.4 mm long, glabrous, 5-locular with 2-3 ovules per locule; styles 5, free, sparsely glandular hairy in distal part, in 3 series with 1 series per plant, shortest 1.5 mm long, middle 4.0 mm long, longest 7.0 mm long; stigmas yellow-green, cup-shaped, fimbriate. Fruit a 5-locular capsule, globular, not longer than sepals, light green. Seeds without endosperm. Pollen tricolporate, triangularly rounded in equatorial view, spherical in polar view, tectum coarsely reticulate with intraluminary bacules clustered along the muri.
