Larryleachia cactiformis (Hook.) Plowes

Dwarf shrublet, branching from base, with 1-10 stems. Stems 40-150(-200) mm long, 30-60 mm thick, erect, cylindrical clavate, whitish to grey-green; tubercles flattened rounded polygonal, crowded but arranged into ±12-16 rows along stem, each tipped with small conical to flattened leaf-rudiment <1 mm long. Inflorescences mainly near apex of stem, flowers arising in groups of 1-5, developing successively; pedicel 1-2 mm long, 1 mm thick; sepals ±1.5 mm long, 1.0 mm broad at base, ovate, acute, glabrous except for cilia sometimes on margins. Corolla 6-15 mm diam., campanulate to shallowly campanulate; inside white to pale yellow barred (rarely spotted) with purple-red to ± uniformly purple-red or maroon, covered with obtuse papillae usually each with a small apical bristle; tube 1-3 mm deep, shallowly bowl-shaped to cupular, containing most of gynostegium; lobes 2.0-3.5 mm long, 2.5-5.5 mm broad at base, spreading, usually with recurved tips, broadly ovate-deltate, broadly acute, margins slightly recurved. Corona ±1.5 mm tall, 3.0-4.5 mm broad, spotted and lined with red on yellowish background, ± sessile; outer lobes ±1.5 mm long, ascending, bifid to well below middle into spreading-erect straight to slightly diverging slightly flattened obtuse lobules, laterally fused in lower half to bases of inner lobes; inner lobes ±1.5 mm long, adpressed to backs of anthers and usually not exceeding them (sometimes meeting in centre and slightly overlapping), linear to narrowly deltoid, acute to truncate-emarginate, with ± deltoid erect to slightly spreading dorsal projection near base ± in series with outer lobes, usually white above with red margins.
