Small succulent forming dense to diffuse clump 60-300 mm diam. Stems 50-300 mm long, 8-25 mm thick, decumbent to erect, grey-green to purplish green; tubercles 3-6 mm long, conical, spreading to decurved, joined near base into 4 angles along stem, each tipped with sharp hardened yellow tooth 2-3(-5) mm long, usually with stipular denticles. Inflorescences of 1-3 usually successively opening flowers towards tips of stems; pedicel 1-10 mm long, ±0.5 mm thick, ascending to descending; sepals ±2 mm long, <1 mm broad at base, ovate-lanceolate, acute, usually with recurved apices, dark green. Corolla 4-18 mm diam., ± rotate; inside smooth and glabrous; tube shallow (<1 mm deep) to lacking, containing only base of gynostegium; lobes 2.5-8.0 mm long, 1.5-3.5 mm broad at base, spreading to recurved, deltate to ovate-lanceolate or lanceolate, margins usually very slightly reflexed, mostly with fine flattened twisted usually dark purple cilia. Corona 2.2-3.7 mm diam., narrowing towards base and usually raised on obscurely pentagonal stipe up to 0.5 mm long, often with flaps of tissue projecting downwards around top of stipe; outer lobes 1.0-1.5 mm long, erect to spreading, deeply to shallowly bifid into often widely diverging ± cylindrical lobules, channelled down inner surface towards base, fused laterally to inner lobes at base only; inner lobes <1 mm long, adpressed to backs of and at most slightly exceeding anthers, dorsiventrally flattened at least at base and sometimes ± cylindrical above, with or without swollen obtuse to ridge-like dorsal projection near base.
