Stems 30-150 mm long, 3-5 mm thick, often somewhat subterranean, then slender and becoming thicker on emerging. Pedicel 1.5-6.0 mm long, 0.50-0.75 mm thick, glabrous, ascending; sepals ±1 mm long, 0.25-0.50 mm broad at base, transparent-white, ovate-acuminate, papillate. Corolla 3.5-7.0 mm long, 4-6 mm broad (usually broadest just beyond mouth of tube), bud-like and broadly elliptical to nearly spherical to depressed-globose; outside white to white at base speckled with pale red above coalescing on lobes, glabrous, with small obtuse conical papillae except towards base; inside smooth, with bold irregular deep red spots on lobes and 3 concentric deep red rings in tube all on white background, with stiff erect cylindrical white to red hairs up to 1 mm long in tube and to ± middle of lobes; tube 1.5-2.0 mm long, 3.0-4.5 mm broad, shallowly bowl-shaped, not thickened at mouth; lobes 3-5 mm long, 2.0-3.3 mm broad at base, ascending then becoming horizontal or descending towards apices where remaining fused, deltate, acuminate, slightly convex inside. Corona ±1.2 mm tall, 1.5-2.5 mm broad, raised on short cylindrical stipe ±0.5 mm long, bright yellow, sometimes flecked with red on backs of inner lobes; outer lobes ±0.5 mm long (usually exceeding dorsal projection of inner lobe), ascending, lanceolate-obtuse to acuminate, joined laterally to horizontally spreading flattened projection apically divided into 4-5 obtuse teeth; inner lobes ±0.25 mm long, deltoid to subquadrate, emarginate, adpressed to backs of anthers and usually shorter than them, dorsiventrally flattened.
