Stilbe overbergensis Rourke

A low, erect, rounded, highly divaricate shrublet to 50 cm in height, with a single main stem up to 3 cm in diameter. Branches slender, erect, villous at first becoming glabrescent to glabrous later. Leaves 3-6 mm long, 3-nate, ericoid, patent; linear-subulate to semi-terete, apex acute; minutely petiolate, margins revolute; pubescent on under surface, otherwise glabrous. Inflorescence a sessile terminal spike 5-12 mm long. Flowers solitary, sessile, each subtended by a leaf-like bract. Floral bracts two, opposite, 2 mm long, narrowly lanceolate, acute, prominently keeled and cymbiform distally; upper surface villous. Calyx tubular, very slightly bilabiate, abaxially curved, 2-2.5 mm long; composed of 5 fused sepals, sepal lobes lanceolate and ciliate, villous on inner surface; outer surface of calyx glabrous. Corolla tubular, bilabiate, 3-4 mm long, very slightly abaxially curved; throat slightly dilated with a ring of dense pubescence on the inner surface; the two posterior corolla lobes erect, oblong-obtuse, 1.5-2 mm long, the three anterior lobes patent, lanceolate acute 1 mm long. Stamens four, subequal, inserted between the corolla sinuses of the anterior lobes; posterior stamen absent; filaments filiform, 2 mm long; anthers basifixed dehising longitudinally. Style filiform, 6-7 mm long, glabrous, arising from the abaxial surface of the ovary. Ovary oblong, 1 mm long, slightly compressed in vertical plane, potentially 2 chambered but the abaxial chamber abortive, leaving a single adaxial chamber with a solitary basal ovule.
