Orbea miscella (N.E.Br.) Meve

Minute succulent forming several small clumps each 20-100 mm diam. connected by ± horizontal rhizomes. Stems above-ground 10-70 mm long, 4-8 mm thick, very slender, decumbent, sometimes running beneath surface for up to 150 mm, uniformly green to brown-or purple-green; tubercles 1-2 mm long, arranged in and partly joined into 4 obtuse angles along stem with groove between angles, tapering into short spreading conical acute tooth, without stipular denticles. Inflorescence 1(-2) per stem near base, of 1-3 flowers developing in gradual succession from short peduncle, with few lanceolate bracts 1-2 mm long; pedicels 4-18 mm long, 1.5 mm thick, erect, holding flower facing upwards, flecked with brownish; sepals 2-3 mm long, 1 mm broad at base, ovate-lanceolate, acuminate. Corolla 10-18 mm diam., rotate, deeply lobed, usually evil-smelling; outside smooth, pale green; inside dark purple-brown, lightly to deeply reticulated rugulose but not papillate; tube ±1 mm deep, containing lower half of gynostegium, formed by thickened (0.5 mm) raised to incurved pentagonal annulus (sometimes divided into 5 raised ± isolated islands, 1 below each lobe); lobes 4-7 mm long, 2.5-3.0 mm broad at base, spreading to recurved, ovate-lanceolate to lanceolate, acuminate to acute, convex from reflexed margins, eciliate. Corona ±3 mm tall, 2.5-4.5 mm broad, raised above base of tube on short pentagonal stipe (<0.5 mm long), dark purple-brown to nearly black; outer lobes ±0.5 mm long, 1 mm broad, spreading to touch surface of corolla at mouth of tube, ± transversely rectangular with slight to deep deltate notch in apex; inner lobes 0.5-1.0 mm long, adpressed to backs of anthers but usually much shorter than them, slightly to strongly dorsiventrally flattened, ± deltoid and obtuse or rarely ± rectangular and broadening towards deeply emarginate apex, sometimes with small obtuse dorsal gibbosity near base, joined to outer series dorsally towards base.
