Stemless geophyte, 50-70 mm tall when in flower. Bulb ovoid, acute at apex to form a narrow beak, 9-11 mm x 5-7 mm; tunics thin, imbricate, light to medium brown, smooth, glabrous. Rhizome glabrous, up to 60 mm long, with a single, light brown, triangular bract at each node, sessile axillary bulbils present at lower nodes. Leaves 10-12(-20), basally congested, petioles 23-56 mm long, glabrous, slightly broadened below the articulation, leaflets 3, lateral leaflets sessile, medial leaflet sessile to very shortly (0.5 mm) petiolulate, conduplicate, glabrous, narrowly elliptic to elliptic, 8-19 mm x 5-10 mm, apices obtuse to retuse, with two prominent round to oblong calli abaxially just below apex, sometimes with 1-6 less conspicuous calli continuing along upper margin, margins entire, reddish. Inflorescence one-flowered, subtended by two alternate bracts inserted just below flower, bracts narrowly triangular, 1.5-2 mm x 0.8-1.0 mm, glabrous, with prominent apical calli. Flowers 17-18 mm long, white with funnel-shaped yellow tube, sepals 5, lanceolate, 6.0 mm x 1.0 mm, glabrous, apices acute, margins entire, prominently bicallose. Petals 5, glabrous, obliquely obovate with a narrow claw, 8-10 mm x 6-8 mm; apices retuse with a cluster of 5-10 irregularly rounded to oblong orange calli abaxially near apex, claw 3.5-4 mm long. Reproductive structures morphologically tristylous, long-level organs 5 mm long, mid-level organs 4 mm long, short-level organs 2 mm long. Stamens 10, in 2 whorls of 5 each, filaments glabrous, longer filaments with a prominent toothlike basal appendage reaching up to about half the length of the filament; anthers oval, dorsifixed. Pollen tricolpate, micro-reticulate. Ovary with 3-5 ovules per locule, narrowly oblong, upper half scattered with simple hairs; styles 5, basally united for 1-2 mm, sparsely covered with simple and glandular hairs; stigma fimbriate.
