Stems 10-100(-150) mm long, (4-)6-22 mm thick, decumbent and occasionally rhizomatous, green to reddish green; tubercles 3-5 mm long, conical, fused near bases into 4-5(-6) broadly obtuse rows along stem with groove between them, abruptly narrowing into narrowly deltoid leaf-rudiment 1.5-2.0 mm long subtended by small stipular glands. Inflorescences 1(-3) per stem arising mainly in lower half, each of 1-3 flowers opening in gradual succession, with few small lanceolate bracts 1-3 mm long; pedicel 10-25 mm long, 1.5-2.5 mm thick, spreading with ascending apex, holding flower facing upwards close to ground, purplish green; sepals 3-6 mm long, 1.0-2.5 mm broad at base. Corolla 18-30(-35) mm diam.; outside pale brownish green; inside pinkish red to chocolate to dark purple or nearly black, often shiny on lobes; annulus (1.0-)2-5 mm tall, 6-12 mm broad, circular to pentagonal, vertically sided, with white to yellow spots on top and in tube, often covered with hair-like papillae 0.4-1.5(-2.2) mm long; tube 1.5-3.0 mm deep; lobes 9-15 mm long, 3-5(-9) mm broad at base, folded tightly along midrib for at least half of length and there narrowly linear-acute, sometimes with clavate vibratile cilia up to 2.5 mm long along margins in lower half. Corona 3-5 mm tall, 4.5-7.0 mm broad; outer lobes forming circular to pentagonal disc spreading at or just inside mouth of tube, reddish brown, orange-to purple-brown; inner lobes 0.5-1.5 mm long, with ascending obtuse dorsal projections 1.0-1.5 mm long, yellow to brownish purple.
