Dwarf succulent forming low dense mats. Stems 10-20(-30) mm long, 5-8 mm thick (excluding teeth), erect, purplish green; tubercles 2-3 mm long, deltoid, spreading, laterally flattened towards base and there joined into 4-5 angles along stem, abruptly narrowing into acute tooth slightly flattened above. Inflorescence with 1-5 flowers developing successively from short peduncle; pedicel 4-8 mm long, ±1 mm thick, spreading with ascending apex holding flower facing upwards; sepals 3-7 mm long, 1 mm broad at base, ovate-acuminate, recurved towards apices. Corolla 10-15 mm long, 12-22 mm diam., campanulate to cylindrical; outside smooth with 3-5 heavy paler raised longitudinal veins on lobes and upper parts of tube, purple-red mottled on cream; inside cream, irregularly concentrically purple-red lined towards base of tube with lines coalescing around corona but above reduced to blotches and spots, smooth and shiny towards base of tube, above densely papillate with slenderly conical or somewhat dorsiventrally compressed and obtuse to shortly apiculate papillae up to 1.0-1.2 mm long (max. length in mouth of tube); tube 6-11 mm diam., deeply cupular; lobes 5-7 mm long, 6-8 mm broad at base, erect to widely spreading, deltate, acute, sometimes with thickened erect papillate margin. Corona 4-5 mm tall, 4 mm broad, without basal stipe; outer lobes broadly triangular to bidentate, fused to base of tube in lower half, deep maroon; inner lobes 2.5-4.0 mm long, maroon streaked with pale yellow, below adpressed to backs of anthers, somewhat dorsiventrally flattened and broadened into transversely gibbous base, above ± terete connivent, then (above middle) divergent and slightly tapering to obtuse or slightly clavate papillate-bristly apex.
