Characteristics

Dwarf succulent forming dense clump up to 200 mm diam. Stems 10-30(-50) mm long, 10-20 mm thick, very shortly decumbent, short and stout, grey-green sometimes mottled with purple-red; tubercles 3-5 mm long, deltoid, spreading, laterally flattened and joined into 4(-5) angles along stem. Inflorescence of 1-5 flowers developing in gradual succession, arising near base of stem on short peduncle (up to 5 mm long) with fine lanceolate bracts 2-3 mm long; pedicel 4-12 mm long, 1.5 mm thick, ascending to spreading with ascending apex, holding flower facing upwards or outwards; sepals 3-4 mm long, ±1.5 mm broad at base, attenuate. Corolla 25-40 mm diam., rotate with short tube in centre; outside smooth, cream to greenish sometimes speckled with maroon, with 3-5 raised longitudinal veins running from lobes to base of tube; inside cream to pale greenish yellow with rounded red-brown to maroon spots becoming larger and coalescing transversely towards mouth of tube and changing to narrow concentric broken red-brown to maroon lines in tube with solid red-brown to maroon patch around corona, covered (mainly on lobes) with minute cream to maroon swollen-acute-tipped papillae changing near bases of lobes to larger obtuse conical papillae (±0.5 mm long) each tipped by slightly clavate bristle 1-2 mm long and continuing to just below mouth of tube; tube 5-6 mm long, 6-8(-12) mm broad at mouth, often slightly constricted at mouth, cupular, with corolla very slightly thickened towards mouth; lobes 7-12 mm long, 9-11 mm broad at base, spreading to recurved, narrowly deltate, acuminate. Corona ±5 mm tall, ±5 mm broad, without basal stipe; outer lobes spreading on base of tube and mostly fused to it, 5-lobed with each lobe bifid near apex, deep maroon; inner lobes ±3 mm long, maroon to reddish, adpressed to backs of anthers near their base, rising above their apices and connivent then diverging slightly, dorsiventrally flattened around laterally broadened base becoming terete above and tapering gradually to fine apex.
