Compact clump-forming small succulent up to 150(-300) mm diam. Stems 30-100 mm long, 6-15 mm thick, erect to spreading, tapering slightly towards apex, pale green to reddish; tubercles very obscure so stem obscurely and very obtusely 4-angled to almost cylindrical, without apical tooth. Inflorescences 1-2 arising randomly on stem but mainly towards base, bearing 1-2 flowers developing in gradual succession on stout peduncle up to 5 mm long; pedicel 60-140 mm long, 2-3 mm thick, mostly prostrate with upturned apex holding flower facing upwards; sepals 3-5 mm long, 1.5 mm broad at base, narrowly deltoid, acute. Corolla 30-40 mm diam., shallowly campanulate; outside pale green spotted with maroon; inside with dark red-brown patch around corona changing to white on rugosities with red-brown in between them on most of tube and at least on bases of lobes, then usually uniformly beige or brown or red-brown for rest of lobes, reticulately rugulose all over except towards base of tube, with small nearly spherical to elongated clavate papillae around corona; tube 5-8 mm deep, pentagonal, cupular, with corolla thickened towards base and forming overhanging ‘annulus’ near base; lobes 12-25 mm long, 7-10 mm broad at base, ascending to spreading, narrowly ovate to deltate, acute, convex above from recurved margins, eciliate. Corona ±6 mm tall, 5 mm broad, raised on short very stout stipe; outer lobes ±1 mm long, ascending and closely adpressed to sides of tube, laterally fused to bases of inner lobes so as to form pouch between adjacent inner lobes, with crenulate-papillate and dentate margin sometimes with distinct central tooth, yellow-brown to blackish; inner lobes 3-4 mm long, adpressed to backs of anthers then connivent and erect in small column and slightly diverging towards apices, dorsiventrally flattened becoming slightly clavate-tuberculate towards apex, with irregularly papillate dorsal crest near base confluent with outer lobes, usually red, sometimes blackish towards tips.
