Characteristics

Small succulent forming spreading clump 60-300 mm diam. Stems 20-70(-100) mm long, 8-10 mm thick, decumbent-ascending, pale green often glaucous; tubercles 3-8 mm long, deltoid-acuminate, spreading, laterally flattened and joined towards base into 5 sometimes slightly spiralling angles along stem, often tapering into sharp, yellow-tipped spike 2-3 mm long. Inflorescence usually 1 per stem, of 1-3 flowers developing in gradual succession from lower half of stem on short peduncle (<5 mm long) with few filiform bracts 5-7 mm long; pedicel 15-60 mm long, 2 mm thick, spreading with upturned apex holding flower facing upwards on ground; sepals 7-12 mm long, 1.0-1.5 mm broad at base, narrowly ovate-attenuate to filiform, obtusely keeled. Corolla 30-50 mm diam., ± rotate beyond mouth of tube; outside covered with conical obtuse papillae especially on tube, greenish cream suffused with pink, with 3-5 heavy raised longitudinal veins running down each lobe; inside with concentric lines and dots of red-brown to maroon on cream, lines becoming finer and denser in tube and coalescing towards base, becoming coarser outside tube, covered from just inside mouth of tube to tips of lobes with obtuse columnar usually dorsiventrally flattened papillae, papillae marked with brown-red/maroon spots and lines, longest just outside mouth of tube (3.0-5.5 mm long) and often forming rows along margins of lobes, each with a minute apical bristle; tube 5-6 mm long, 10-12 mm broad at mouth, broadly cupular and slightly constricted at mouth by thickening in corolla, cylindrical; lobes 12-15 mm long, 12-15 mm broad at base, spreading to reflexed, deltate, acute to shortly attenuate. Corona 6-7 mm tall, 5-6 mm broad, without basal stipe; outer lobes 0.5-1.5 mm long, very short and ± rectangular (sometimes fused and nearly disc-like) to somewhat longer than broad, bifid to emarginate, spreading on base of tube and fused to it towards their base, cream often with maroon dots along margins to dark maroon; inner lobes ±4 mm long, white to greenish cream towards base, maroon speckled on cream on upper swollen part, erect, dorsiventrally flattened and linear from a slightly dorsally gibbous base, abruptly expanded at apex into inverted ± foot-to hoof-shaped fleshy appendage.
