Shrub, ca. 0.5 m tallwith silvery, corky bark, branched. Branches to 0.6 cm in diam., semi-terete, dark purple, rigidly 4-winged; internodes 0.2-1 cm long. Leaves clustered towards tip of branches at maturity; petioles 0.1-0.5 cm long, flattened; blade subcoriaceous, suborbicular, (0.7-)1-1.5 x (0.5-)0.8-1.2 cm, longer than internode, margin obviously revolute, apex obtuse, base obtuse to acute, attenuate; 3-veined, veins very distinct, impressed above, prominent beneath. Inflorescence dense panicles, terminal and in upper axils, 1-3 cm longincluding 0.3-0.6 cm long peduncle; bracts and bracteoles linear, 1-2(-3) mm long(basal bracts often leaf-like); pedicels (0.8-)1-2(-4) mm long. Flowers 5-merous; calyx dark purple, 1.5-2.5 mm long, lobes narrowly triangular, ca. 1.6 x 0.6 mm long, margin entire, apex acute, connate1/5-1/4 from base, small glands at base on inside; corolla dark purple to orange, urceolate/campanulate, ca. 4 mm long, tube 2.6-3 mm long (longer than calyx lobes), lobes broadly ovate, ca. 1 x 0.8-1.2 mm, papillose, margin entire, apex acute, sometimes somewhat recurved at maturity, connate ca. 3/4 from base; stamens ca. 1.5 mm long, filament ca. 1 mm long, straight, equal in length, inserted ca. halfway from tube base, no appendages present, anthers broadly ellipsoid, ca. 0.5 mm long; pistil ca. 2.5 mm long, ovary narrowly ovoid, ca. 2 mm long, gradually tapering into short style, style ca. 0.5 mm long, stigma capitate. Fruit narrowly ovoid-ellipsoid (capsule halves incurved after dehiscence so that capsule appears subspherical), 5-6 x 2 mm, including 0.5 mm long persistent style, calyx persistent (star-like); seeds irregular in shape, narrowly ellipsoid, laterally flattened, ca. 1.5 x 0.5 mm.
