Dwarf succulent forming small clump, sometimes extensively rhizomatous. Stems 30-100 mm long, 6-8 mm thick (excluding teeth), sometimes forming rhizomes up to 150 mm long, slender, erect to shortly decumbent, pale green flecked with purple-brown; tubercles 4-10 mm long, arranged into 4 obtuse rows along stem with slight groove between rows, tapering into slender spreading conical tooth, with pair of much reduced to obsolescent stipular denticles shortly below apex. Inflorescence 1 per stem near base, of 1-3 flowers developing in gradual succession, with few concave narrowly ovate acute bracts 2-3(-6) mm long and 1.5 mm broad at base; pedicel (15-)20-25 mm long, 2 mm thick, heavily streaked with purple-brown on green, ± horizontally spreading often with upturned apex, holding flowers facing horizontally or upwards; sepals 5-12 mm long, 2-3 mm broad at base, narrowly ovate, acute or acuminate. Corolla 35-55 mm diam., rotate to somewhat reflexed right from centre, usually with lobes slightly reflexed; outside glabrous, pale green suffused with purple-brown, with 3-5 longitudinal purple-brown veins along each lobe; inside smooth and somewhat shiny, dark maroon to brown-red with few to many irregular transverse yellow markings towards tips of lobes or with maroon spots on yellow background; tube 2.0-2.5 mm long, ±5 mm broad, cupular, bounded by annulus that is abruptly to gradually raised 1.5-2.0 mm above surface of corolla and abruptly to gradually merging with rest of surface, pentagonal; lobes 12.5-20.0 mm long, 9.0-13.5 mm broad at base, spreading and often reflexed, ovate-deltate, shortly acuminate, rarely slightly rugulose towards tips, margins not folded back, with clavate vibratile maroon marginal cilia up to 3 mm long except at tips. Corona ±4 mm tall, 6.5-7.0 mm broad, raised well above base of tube on dark maroon obtusely pentagonal stipe ±1.5 mm long and 2.5 mm thick; outer lobes ±1.5-2.0 mm long, 1.5-2.0 mm broad, subquadrate, spreading and touching upper rim of annulus, truncate to obtusely 3-4-dentate, emarginate, dark maroon; inner lobes 1-2 mm long, adpressed to backs of anthers and shorter than to slightly exceeding them, ± ovate, acute to truncate, slightly gibbous on rear, irregularly and sparingly dentate on margins, yellow minutely speckled with red.
