Characteristics

Dwarf succulent forming a dense clump 100-500 mm diam. Stems 15-60(-200) mm long, 8-20 mm thick (excluding teeth), erect to decumbent, grey-green to purplish; tubercles 3-6 mm long, spreading, deltoid, laterally flattened towards base and joined into (4-)5(-6) angles usually spirally twisted along stem, tapering into stout hard acute yellowish tooth slightly flattened above. Inflorescence of 3-20 flowers developing in quick succession (often 2-3 open together), arising from short sometimes branched broad peduncle (3-25 mm long) with lanceolate bracts 2-5 mm long; pedicel 5-25 mm long, 1.5-2.0 mm thick, spreading to ascending, holding flower facing upwards or horizontally; sepals 3-8 mm long, 1.5 mm broad at base, ovate, acuminate, somewhat recurved towards apex. Corolla 18-25 mm diam., campanulate to rotate with cupular tube in centre; outside smooth, pale brown to flesh-coloured usually with 1-5 raised longitudinal veins running down centre of lobe; inside cream to white, with purple-red spots and concentric broken lines usually from tips of lobes to base of tube becoming finer in tube and coalescing into irregularly pentagonal purple-red patch around corona, covered with obtuse conical slightly dorsiventrally flattened whitish papillae (most prominent around mouth of tube where reaching 1 mm long, becoming shorter on lobes and ending abruptly just inside mouth of tube) often with apical bristle <0.25 mm long; tube 5-8 mm long, 8-13 mm broad at mouth, cupular and slightly pentagonal, often somewhat constricted at mouth; lobes 5-6 mm long, 7-11 mm broad at base, spreading, with apices slightly recurved, deltate, acute. Corona 4-6 mm tall, 3.0-5.5 mm broad, without basal stipe; outer lobes 1-2 mm long, divided into deltoid lobules near apex to truncate and subquadrate, pale yellow suffused with pink and with maroon patch near base; inner lobes 2.0-2.5 mm long, bright yellow, below adpressed to backs of anthers and somewhat dorsiventrally flattened and broadened into transversely conspicuously gibbous base, above connivent-erect tapering slightly to obtuse slightly bristly often reddish apex.
More
Succulent perennial herb, 80-200 mm tall. Stems 4-5(6)-angled, tuberculate-toothed, teeth mostly tipped with hardened acute point. Corolla campanulate, (20-)25-35 mm in diameter, limb and lobes regularly and boldly, transversely lined, evidently papillate. Inner corona lobes much exceeding anthers, subulate or narrowly triangular-obtuse (attenuate). Flowers greenish with brown-red spots and concentric broken lines; corona light greenish yellow.
