Larryleachia perlata (Dinter) Plowes

Shrublet branching from base, with 1-10 stems. Stems 50-300 mm long, 25-60 mm thick, erect, cylindrical clavate; tubercles flattened rounded polygonal, arranged into 12-14 rows along stem, each with small conical to flattened persistent leaf-rudiment <1 mm long. Inflorescences mainly in upper parts of stem, flowers in groups of 3-6(-12) on often large ‘peduncular patches’, opening in rapid succession (often several per cluster open at once), with strong excrement odour; pedicel 0.5-2.0 mm long, 1 mm thick; sepals 1.0-1.5 mm long, 0.5-1.0 mm broad at base, ovate, acute, margins usually ciliate with transparent thick hairs, otherwise glabrous. Corolla (5-)7-10 mm diam., rotate; outside yellow-green; inside grey to greenish white to grey spotted with deep maroon to entirely deep maroon, covered densely with obtuse conical papillae each tipped with a horizontally spreading cylindrical obtuse bristle; tube 1.0-1.5 mm deep, shallowly cupular, containing gynostegium up to level of bases of inner lobes, not thickened at mouth; lobes 3.0-4.5 mm long, 2.0-2.5 mm broad at base, strongly reflexed and pressed against stem with bases raised into ‘annulus’ around mouth of tube, often with paler slightly raised medial ridge, narrowly ovate-deltate, acuminate, margins folded back strongly so inside convex. Corona ±2.5 mm tall, 2.0-3.5 mm broad, irregularly red-to maroon-spotted on yellow to whitish background, ± sessile; outer lobes ±1 mm long, ascending, bifid to near middle into divergent spreading dorsiventrally flattened lobules up to 0.5 mm long or emarginate and truncate, laterally fused in lower half to bases of inner lobes to form pouch; inner lobes ±0.5 mm long, adpressed to backs of anthers and sometimes exceeding them, occasionally with erect apices, deltoid to rectangular, acute to truncate or emarginate, with broad truncate nearly erect dorsal projection at base in series with outer lobes.
