Characteristics

Slender, caulescent, 3-5 cm high, usually somewhat tufted. Bulbs lanceolate or elongate-lanceolate in outline, often slightly tortuous, up to 4.5 cm long, congested, the bulbils budding from within the old bulb, forming a structure which resembles a branched tuber; tunics papery, imbricate. Rhizomes, both the living and the previous years’, closely fascicled, up to 6 cm long, arising together through the apex of the old parent bulb. Stem rigid, up to 4 cm long, rarely branched, dark green, minutely pubescent, with 1-2 scales. Leaves 6-12, apically congested; petioles pubescent, 0.5-1.5 cm long; leaflets 3, linear-oblong, often slightly cuneate, conduplicate-falcate, emarginate, 5-9 mm long, 1.5-3 mm broad, glabrous above, pubescent beneath, ciliate. Peduncles 1-fld., terminal, 5-8 mm long, pubescent, with 2 small subulate ciliate bracts often imbricating the calyx. Sepals broadly lanceolate, 2.5-3 mm long, pubescent, erispato-ciliate, purple-margined below, blackish towards the apex, with 2 elongate apical calli. Corolla 1.2-1.5 cm long, pale lilaceous, with a somewhat narrowly funnel-shaped yellow tube; petals oblanceolate, attenuate at the base or sub-spathulate, 2.5-3 mm broad, violet-veined, with 2 purple marginal striae about 1 mm long, a little below the middle. Filaments, the shorter 2-3.5 mm, the longer 3-6 mm long, glandular-pilose, edentate. Ovary pubescent on the upper half, ecallose, the chambers 2-ovuled; styles pubescent at the base, pluricellular-pilose above. Seeds without endosperm.
