Succulent spreading to form loose clump or pendent from ledges on cliffs. Stems 40 mm-2(-3) m long, 6-20 mm thick, prostrate or ascending then soon arching back to ground and sometimes somewhat rhizomatous, square in cross-section, blue-green; tubercles very obscure, without apical tooth. Inflorescence 1 to several, arising towards apex of stem, each bearing 1-5 flowers opening in gradual succession, flowers continuing over several seasons (as stem lengthens) on gradually lengthening peduncle 5-30 mm long; pedicel 12-15 mm long, 2 mm thick, ascending then spreading so that flower facing ± horizontally; sepals 2-3 mm long, 1 mm broad at base, ovate to lanceolate, acute. Corolla 20-25 mm diam., tubular-campanulate; outside faintly mottled with brownish to purplish pink becoming darker towards apex of lobes; inside brownish to purplish red, markedly to slightly transversely rugulose except in lower half of tube and towards tips of lobes, sometimes with small nearly spherical to clavate papillae all over; tube 7-15 mm long, 12-14 mm broad, strongly pentagonal to circular in cross-section, conical to nearly cylindrical, with corolla thickened in lower half except near base so that distinctly overhanging ‘annulus’ arises near base; lobes 5-8 mm long, 7-10 mm broad at base, erect to spreading, deltate, acute, margins recurved so that inner surface distinctly convex, sometimes with clavate vibratile cilia up to 2 mm long near base. Corona 6-7 mm tall, 4-5 mm broad, red to purple towards extremities, yellow towards base, raised on distinct stipe becoming very broad towards base; outer lobes 2.0-2.5 mm long, ±1 mm broad, ascending to erect, ± rectangular, divided in upper 1 mm into 2 erect acute teeth and a small truncate toothlet between them to truncate and finely and equally 3-toothed, deeply channelled down inner surface; inner lobes 4-5 mm long, adpressed to backs of anthers then erect and connivent then spreading towards apices, dorsiventrally flattened in lower ±2 mm then terete and filiform, somewhat rugulose at slightly clavate apex, with nearly erect slender laterally flattened obtuse dorsal horn 3.0-3.5 mm long arising near base.
