Leaves coriaceous, flat, ovate, 3-8 x (1.5-)2-3.5 cm, base subcordate or rounded, apex long-acuminate, essentially glabrous but sparsely hispid along the midrib beneath and near margin above; obscurely 5-plinerved, midrib impressed above and raised beneath, lateral nerves obscure; petiole 1-1.5 mm long, hispid with hairs ca. 0.7 mm long. Inflorescence short-racemose, 5-8-flowered; rachis slender, up to 1 cm long, glabrous, surrounded at base by numerous, ovate, acute, ciliate bracts to 2 mm long; floral bract deciduous, lanceolate-oblong, ca. 2 mm long, ciliate; pedicel subterete, angled, striate, rugose, 10-20 mm long, glabrous or sparsely hispid; bracteoles medial to basal, linear, ca. 1-1.5 mm long, sparsely hispid. Flowers with calyx 3-6 mm long, glabrous or hirsute; hypanthium obconic, rugose, 2-4 mm long; limb campanulate, spreading, 1.5-2 mm long; lobes apiculate, less than 1 mm long, sometimes obscure at anthesis; sinuses flat; corolla cylindric, 10-11 mm long, glabrous or sparsely pilose at apex when young, bright red with pale pink lobes, the lobes strongly reflexed, deltate, acute, 1-1.5 mm long; stamen ca. 9 mm long, slightly dimorphic; filaments ca. 1.5-2 mm long, glabrous; anthers ca. 7 mm long; thecae smooth, ca. 2.5 mm long; tubules 5.5-6 mm long, dehiscing by elongate pores ca. 2 mm long; style exserted, glabrous; nectariferous disc densely hirsute with short, white hairs.
