Small succulent 60-150 mm diam. Stems 30-120 mm long, 8-15 mm thick; leaf-rudiments 1.5-5.0 mm long, subulate. Inflorescence with few flowers developing in rapid to gradual succession on spreading to erect peduncle 5-20 mm long; pedicels 15-30 mm long, 1-2 mm thick, erect to spreading; sepals 2.5-4.0 mm long, 1.7-2.0 mm broad at base, narrowly deltate to ovate, acute to acuminate. Corolla 20-35 mm diam., rotate to slightly cupular or conical; outside pale green, marked sometimes heavily with dark purple; inside cream with purple-brown to red-brown spots which become larger and more crowded towards margins and apex and merge to form continuous dark border, sometimes faintly rugulose or with low dome-shaped papillae each with minute apical bristle; tube 1-2 mm deep, cupular, with corolla much thickened around mouth (below bases of lobes); lobes 6-10 mm long, 6-10 mm broad at base, spreading to recurved, ovate to deltate-ovate, acute, sometimes with marginal cilia. Corona ±5-7 mm tall, 5-7 mm broad, raised on short stipe; outer lobes ±2.5-3.0 mm long, 1 mm broad, ascending, narrowly deltoid, acute to broadly obtuse to shortly to deeply bifid (lobules diverging), slightly channelled on inner surface, purple-brown; inner lobes 3-5 mm long, connivent then ascending in narrow column and often recurved towards apices, terete and ± filiform above anthers, obtuse, sometimes with small dorsal gibbosity to laterally flattened horn near base, cream marked with purple.
