Rigid ascending suffrutices, 30-50 cm tall; stems leafy and branched above, leafless below with prominent nodes, branches and leaves notate with shiny, microscopic, subcutaneous cells. Leaves coriaceous, somewhat corrugated on both surfaces, from broadly to narrowly elliptic, sometimes oblong-, ovate-or lanceolate-elliptic, 1.7-3.5 cm long, 0.5-1.8 cm broad, rounded or acute at the apex, margins narrowly revolute. Cymes terminal, monochasial, 3-fiowered or reduced to a solitary flower; pedicels short or 0; flowers bibracteate at the base; bracts 6-18 mm long, 1.3-4 mm broad at the base, acuminate to an obtuse or acute apex. Calyx 9-16 mm long, divided beyond the middle; lobes acuminate from a broad base to an obtuse or acute apex, obscurely carinate. Corolla 'magenta pink', 2.2-2.8 cm long; tube rather thin textured, slightly narrowed in the throat and widened at the mouth, about 1.2 cm long; lobes elliptic to subrotund and cuneate into a claw-like base, usually obviously longer than broad, 1.2-2.8 cm long, 0.8-1.1 cm broad. Stamens inserted just below the throat; filaments about 4 mm long; anthers about 4 mm long not spirally twisted. Ovary about 1 cm long, attenuate into the style; style shorter than the ovary, about 8 mm long; stigma peltate, stigmatic surface prominent.
