Dwarf succulent forming dense clump 30-300 mm diam. Stems 15-40(-60) mm long, 8-15 mm thick, decumbent, pale green to faintly suffused with reddish; tubercles 2-5 mm long, deltoid, spreading, laterally flattened and weakly joined towards base into mostly 5 angles along stem, abruptly narrowing into fine spreading acute tooth, somewhat flattened on upper surface. Inflorescences 1-3 per stem, each of 1-5 flowers developing in gradual succession on peduncle up to 15 mm long with few narrowly acute bracts 2-4 mm long; pedicel 7-25 mm long, 1.5-2.0 mm thick, ascending with spreading apex holding flower facing horizontally or nodding, green to purplish; sepals 3-7 mm long, 1 mm broad at base, narrowly ovate-attenuate, green. Corolla (16-)20-30(-35) mm diam., rotate beyond mouth of tube to campanulate; outside smooth to somewhat irregularly roughened, cream to reddish with 1 heavy (+2-4 lighter) raised longitudinal veins running down each lobe; inside cream, immaculate to finely spotted or rarely barred with maroon, smooth in lower half of tube, rest covered with low conical papillae at most 0.5 mm long (densest and longest at mouth of tube) each sometimes with minute apical bristle; tube 3-5 mm long, 5-7 mm broad at mouth, shortly cupular and somewhat constricted at mouth by thickening of corolla, without annular swelling around mouth; lobes ±5-8 mm long, 7-10 mm broad at base, erect to spreading, deltate, acute to slightly acuminate. Corona 3.5-4.0 mm tall, 3.5-5.0 mm broad, without basal stipe; outer lobes subquadrate, emarginate to deeply bifid, spreading on base of tube and fused to it towards base, yellow to maroon; inner lobes 1.0-1.4 mm long, yellow sometimes with maroon markings, adpressed to backs of anthers for half anthers’ length then sometimes slightly ascending and connivent, dorsiventrally flattened with slight dorsal gibbosity at base, tapering gradually to ± terete and smooth to bristly apex.

It is a subtropical plant. It grows in coastal areas.
