Characteristics

Small succulent forming dense to loose low clump up to 150(-300) mm diam. Stems 15-60(-180) mm long, 7-15 mm thick (excluding teeth), erect, ± cylindric or narrowly ovoid; tubercles 4-10 mm long, spreading, conical, arranged loosely in (9-)10-16(-24) vertical or sometimes spiralling rows, tapering into slender soft bristle 2-8 mm long. Inflorescence with 1-5 flowers developing in gradual succession on short peduncle; pedicel 2-8 mm long, 1 mm thick, ascending and holding flower facing upwards; sepals 8.5-12.5 mm long, narrowly ovate-attenuate. Corolla 30-50 mm diam.; outside yellowish to pinkish becoming cream towards base, smooth with 3 raised longitudinal veins on lobes and upper part of tube; inside densely papillate, cream to pale yellow densely and finely flecked with red or rarely uniformly red, covered except in lower half of tube with cylindric obtuse to slightly subclavate papillae to 1 mm long (longest at mouth of tube) sometimes tipped with minute bristle, papillae pale yellow banded and striped with red; tube 5-9 mm long, 6-8 mm broad at mouth, cupular to subcylindrical; lobes 12-22 mm long, 6-8 mm broad at base, spreading to recurved, narrowly deltate, acuminate to attenuate. Corona ±4 mm tall, 4 mm broad, dark maroon, without basal stipe; outer lobes fused to tube only at base, deltoid to broadly quadrate; inner lobes 1.8-2.5 mm long, erect, dorsiventrally much flattened, somewhat gibbous at widened base, tapering slightly to bristly clavate apex.

Perennial succulent. Stems erect, cylindrical to narrowly ovoid, 15-60(-180) x 7-15 mm, grey-green, (9)10-16(-24)-angled with vertical to spiralled rows of tubercles, each tubercle tipped with a 2-8 mm long bristle making the stems look ‘furry’. Flowers 1-5; pedicels 2-8 mm long. Sepals 8.5-12.5 mm long. Corolla 30-50 mm in diam., cream-coloured to yellowish with small red spots; tube campanulate; lobes spreading to recurved, 12-22 mm long; papillate to halfway inside tube, papillae cylindrical, up to 1 mm long, sometimes bearing a small hair. Corona maroon; outer lobes spreading, variable, ± rectangular to triangular; inner lobes erect, dorsiventrally flattened, 2.0-2.5 mm long, tapering to clavate, tuberculate apex.
Like H. barbata but stems cylindrical, with tubercles arranged into 10-16 rows, tubercles tapering into a slender bristle 2-8 mm long, corolla campanulate, inside with conspicuous papillae, each with a minute, apical bristle, inner corona lobes with bristly, clavate tips.
Leafless succulent to 10 cm, with stems cylindrical and tesselated, covered in soft bristles arranged roughly into 10-16, often spiralling rows; sap clear. Flowers like H. longii.
