Small succulent 60-150 mm diam. Stems 30-120 mm long, 8-15 mm thick; leaf-rudiments 1.5-2.5 mm long. Inflorescence with few flowers developing in rapid to gradual succession on spreading to erect peduncle 5-20 mm long; pedicels 20-30 mm long, 2 mm thick, ascending then spreading to hold flower facing outwards or slightly nodding; sepals ±4 mm long, 1.5 mm broad at base, ovate, acute.

Corona ±10 mm tall, 9-10 mm broad, purple-black except for few yellow patches near bases of inner lobes, raised on very short stipe; outer lobes 5.0-6.5(-8) mm long, 1.5-3.0 mm broad at base, ascending, margin conspicuously folded up to form pouch towards base, above narrowly attenuate and channelled on inner surface, acute; inner lobes 8-10 mm long, ±1.25 mm wide at ovate base, connivent then ascending in slender narrow column ± equalling tube, terete and filiform above anthers with minutely obtuse or sometimes minutely clavate apices, without dorsal gibbosity.
