Stems 40-130(-300) mm long, 4-12 mm thick, erect, ± glabrous, bright green tinged with purple towards tips; tubercles 1-2 mm long gradually becoming less prominent with age, fused into 4 obtuse angles along stem; leaf-rudiments 1-2 mm long. Inflorescences finely pubescent, 1-2 per stem, each of 1-10 flowers developing in close succession near base of stems from short peduncle with deltoid bracts 1-2 mm long; pedicel 12-20 mm long, 2 mm thick, spreading, often with upturned apex; sepals 4-5 mm long, 2 mm broad at base, ovate, acute. Corolla 40-55 mm diam., rotate or somewhat convex with reflexed lobes; outside creamy pink with 5 darker veins on each lobe; inside smooth and shiny to faintly rugulose towards centre, pale yellow or orange to pale purple or pale pink becoming paler towards centre, often with faint concentric broken transverse yellow lines towards and below bases of lobes, glabrous except in tube and on margins of lobes; tube ±1.5 mm long, 4 mm broad, closely containing stipe of gynostegium, pentagonal, with mouth somewhat closed by inward-projecting slightly annulus-like thickening of corolla, pubescent towards base; lobes 15-18 mm long, 7-8 mm broad at base, spreading to reflexed, ovate-acuminate, convex above from revolute margins with straight white cilia up to 2.5 mm long. Corona ±4 mm tall, ±7 mm broad, raised on pentagonal stipe ±1 mm long, glabrous; outer lobes 2-3 mm long, 1.5-2.0 mm broad, oblong, widening gradually to obtuse emarginate apex, lightly concave above, spreading-recurved, orange or yellow towards base changing to pale purple towards apex; inner lobes ±1 mm long, adpressed to backs of anthers and slightly exceeding them, dorsiventrally flattened except for dorsal keel becoming more prominent towards base, ovate, acute, orange-brown.
