Characteristics

Stemless, rather succulent, 5-14 cm high, entirely glabrous. Bulb obclavate, up to 7 cm long; tunics loose, light brown, papery, transversely wrinkled, with a smooth, linear-lanceolate acute beak at the apex. Rhizome 25 cm long or more, thick in the upper part, at length bearing numerous large, elongate bulbils on short, underground stolons arising from the scale axils. Leaves 10-30 or sometimes very numerous; petioles flattened, up to 4 cm long, dilated and nerved below the basal articulation; leaflets 3, articulated to the petiole, bright green, sometimes inconspicuously black-dotted, the medial cuneate, obcordately incised at the apex, 1.5-2.4 cm long, 0.7-1.2 cm broad, the lateral somewhat oblique, rather smaller. Peduncles 1-fld., 1-3.5 cm long, with 2 linear-lanceolate bracts, 4 mm long, close to the calyx. Sepals lanceolate or oblong-lanceolate, 7-8 mm long, ecallose. Corolla 2.5-3.5 cm long, pale cream-coloured, with a broadly funnel-shaped yellow tube; laminae of the petals cuneate-obovate, subtruncate, 3-4 times longer than the tapering claw. Filaments sparsely glandular-pilose, the shorter 4-5.5 mm, the longer 6-10 mm long, with short, obtuse teeth. Ovary oblong, 3 mm long, sparsely glandular-pilose at the apex, the chambers 3-ovuled; styles minutely glandular-pilose.
More
Acaulescent, glabrous geophyte, 50-140 mm tall, readily falling apart at articulations when dry. Bulb tunics papery, transversely wrinkled, pale brown. Leaves with a flattened petiole swollen at base, leaflets 3, articulated to petiole, ± 2 times as long as broad, central one cuneate, shortly incised at apex, lateral ones smaller, sometimes ± black-dotted. Flowers 1 per peduncle, with 4.2 mmear bracts close to calyx, pale cream-coloured, with a yellow tube.
