Small succulent 60-300 mm diam., sometimes with some stems spreading beneath the ground then emerging to form new clump. Stems 30-120 mm long, 8-15(-20) mm thick; leaf-rudiments 1-3 mm long, ± deltoid. Inflorescence with few flowers developing in rapid to gradual succession on spreading peduncle up to 20 mm long; pedicel 20-25 mm long, 2 mm thick, ascending and holding flower facing partly upwards; sepals ±3 mm long, ovate, acute. Corolla ±30-40 mm diam., rotate; outside pale green to suffused with brown, with 3-5 longitudinal veins on lobes; inside yellow to green or reddish brown mottled irregularly (sometimes obscurely) with brown to dull purple or red and becoming paler towards centre, with low dome-shaped papillae joined into obscure and irregularly reticulated ridges, each papilla tipped with a minute bristle; tube ±2 mm deep, nearly as broad as corona, shallowly cupular, formed by annular thickening of corolla near its base; lobes 9.0-12.5 mm long, 10-14 mm broad at base, spreading, ovate-deltate, acute to shortly acuminate, slightly convex above from margins slightly recurved especially towards base, with vibratile clavate purple cilia 1.5-3.0 mm long. Corona ±3 mm tall, 7 mm broad, reddish brown, raised on short stipe; outer lobes ±2 mm long, ±2 mm broad at base, ascending then spreading parallel to surface of corolla, trifid; central lobule ±1.5 mm long, narrowly deltoid, acute to obtuse or notched at apex, channelled on inner surface; lateral lobules ± deltoid, diverging, 0.5-1.0 mm long; inner lobes ±1.5 mm long, shorter than to exceeding anthers and meeting in centre but not rising above anthers, narrowly deltoid to ovate, acute to obtuse, near base with small obtuse dorsal gibbosity or hornlet <0.5 mm long.
