Shrub to 2 m, armed; stems unarmed or sparsely prickly, the prickles 2-3 mm long, straight, broad-based, the basal diameter ca. 3 mm, pubescence dense, the trichomes porrect stellate, sessile or short-stalked, ca. 0.7 mm in diameter, the rays 7-10, the midpoint equal to the rays, trichomes drying whitish yellow; new growth densely stellate pubescent, drying whitish; bark of older stems pale to darker grey.
Sympodial units difoliate to plurifoliate, sometimes geminate.
Leaves simple, 3.5-9 x 1-2.5 cm, narrowly elliptic to lanceolate, chartaceous, slightly discolorous and paler beneath, densely stellate pubescent on both surfaces, the underside more densely pubescent and the lamina not visible, the pubescence a mixture of sessile and short-stalked porrect to slightly multangulate stellate trichomes 0.5-1 mm in diameter, the rays equal to the midpoints; primary veins 6-9 pairs, drying slightly yellowish brown; base acute to truncate, slightly oblique; margins entire or occasionally very shallowly lobed or sinuate; apex acute to acuminate; petiole 0.6-2 cm, densely stellate pubescent like the stems.
Inflorescences internodal, occasionally opposite the leaves, 2-4 cm, simple, with 8-14 flowers, densely stellate pubescent with whitish cream porrect stellate trichomes like the stems; peduncle 0.3-1 cm, unarmed; pedicels 1-1.5 cm, tapering to the calyx, ca. 1.5 mm in diameter, erect at anthesis, densely stellate pubescent like the stems and inflorescence; pedicel scars in pairs spaced 1-3 mm apart, the pedicels articulated at the base. Buds strongly curved, somewhat hooked at the apex, the corolla strongly exserted from the calyx tube before anthesis.
Flowers perfect or unisexual, strongly zygomorphic, 5-merous; calyx tube 4-5 mm, conical, the lobes of unequal lengths, 7-10 mm long, linear and awn-like, densely stellate pubescent on all surfaces; corolla 2-3 cm in diameter, dark purple, unequally stellate, lobed ½ to 2/3 of the way to the base, the lobes unequal, planar at anthesis, the three upper lobes ca. 1 x 0.5 cm, triangular, the two lower lobes 1.2-1.6 x 0.6-0.7 cm, curved away from one another at the tips, glabrous adaxially and on interpetalar tissue except for stellate trichomes along the midvein, densely pubescent abaxially with golden short-stalked multangulate trichomes with rays shorter than those of the stem trichomes; anthers dimorphic, the four short anthers 4-5 x ca. 1.5 mm, tapering and poricidal at the tips, the pores not lengthening to slits, the long anther 10-15 x ca. 1.5 mm, ca. 1 mm wide at the apex, strongly curved upwards and tapering to a poricidal tip, the pores not lengthening to slits; filament tube ca. 0.5 mm, the free portion of the filaments 1.5-2 mm, glabrous; style in long-styled flowers 10-16 mm, strongly curved upwards like the long anther, in short styled flowers ca. 2 mm, sparsely pubescent at the base with simple golden trichomes ca. 1 mm long; stigma not enlarged, a minutely papillose tip.
Fruit a globose berry, 1.1-1.5 cm in diameter, orange at maturity, the pericarp thin and shiny, glabrous; fruiting pedicels 1-1.2 cm, woody, slightly nodding, the calyx tube splitting in fruit.
Seeds 5-8 per berry, 5-6 x 4-6 mm, flattened reniform, pale tan or yellowish brown, the surfaces minutely reticulate, the testal cells rectangular with slightly sinuate walls.
