General Information

Shrubs (clonal?) to 2 m. stems erect, ca. 0.5 cm in diameter, sparsely to densely pubescent with uniseriate dendritic trichomes 0.25-1 mm, longer trichomes found in more densely pubescent populations, pubescence extremely variable and correlated over the entire plant; bark red or dark brown, very shiny; new growth sparsely dendritic pubescent like the stems.
Sympodial units (2-)3-foliate, only occasionally geminate.
Leaves simple, (2-)3.5-15 x (0.6-)1-5.7 cm, elliptic to narrowly elliptic, adaxially glabrous to sparsely pubescent with uniseriate simple or dendritic trichomes 0.5-1 mm on the veins and lamina, abaxially glabrous to densely pubescent with uniseriate dendritic trichomes 0.5-1 mm over entire surface, the base attenuate, the margins entire, the apex acute to acuminate; primary veins 10-12 pairs, often drying yellowish; petioles 0.3-1.2 cm, glabrous to densely dendritic pubescent.
Inflorescences internodal or terminal, 2.5-10 cm, many times (to 6x) branched, with 50-200 flowers, sparsely to densely pubescent with dendritic trichomes, the pubescence less dense apically, the peduncle 2-4 cm; pedicels 0.5-0.6 cm, less than 0.5 mm in diameter at the base and apex, nodding at anthesis, sparsely dendritic pubescent; pedicel scars closely packed distally, to 3 mm apart towards the base of the inflorescence, plane with the rachis. Buds globose, the corolla exerted approximately halfway.
Flowers all perfect; calyx tube ca. 1 mm, conical, the calyx lobes 1-1.5 mm, narrowly triangular, sparsely dendritic pubescent abaxially; corolla 0.8-1 cm in diameter, white, lobed ca. 3/4 of the way to the base, the lobes 0.5-0.8 cm, deltate, planar to slightly reflexed at anthesis, glabrous to densely papillate towards the apex abaxially; filaments with the free portion 1-1.2 mm, the tube essentially absent, glabrous; anthers 2-2.5 x ca. 1 mm, poricidal at the tips, the pores lengthening to slits with age; ovary conical, glabrous, the style 4-5 mm, straight, glabrous, the stigma capitate, the surface minutely papillate.
Fruit a globose berry, 0.5-0.6 cm in diameter, bright orange or yellowish at maturity, the pericarp thin, the pulp sticky; fruiting pedicels 0.7-0.9 cm, ca. 2 mm in diameter at the base, swollen just below the berry, ca. 1 mm in diameter at the apex, woody and erect.
Seeds 6-8 per berry, 3-3.5 x 2-2.5 mm, flattened reniform, pale yellowish, the surfaces minutely pitted.
