Small tree 1-6 m tall. Stems glabrous to densely pubescent-pilose with curled eglandular hairs ca. 1-2 mm long.
Sympodial units 4-foliate.
Leaves simple, the blades 3-18 x 1.5-7 cm, 1.5-3 (-4) times as long as wide, chartaceous to membranaceous, elliptic to ovate, sparsely to moderately pubescent-pilose adaxially, glabrous to densely pubescent-pilose abaxially; base cuneate, truncate, or rounded, without basal lobes; margin entire; apex acuminate; petioles 0.5-2 cm, glabrous to densely pubescent-pilose.
Inflorescences 5-30 cm, unbranched, with 4-20 (-30) flowers, all flowers perfect, the axes glabrous to densely pubescent-pilose; peduncle 2-6.5 cm; rachis 3-27 cm; pedicels (10-) 15-25 mm, 20-35 mm in fruit, spaced (1-) 4-15 (-30) mm apart, articulated near the base, leaving pedicellar remnants up to 1 (-2) mm long.
Buds ovoid, acute or obtuse at apex. Flowers with the calyx radius 3-7 mm, the lobes (1.5) 3-6 x 1.5-2 mm, triangular, acute at tips, often dentate at base, chartaceous, moderately pubescent-pilose. Corollas 2.5-3.5 cm in diameter, the radius 10-22 mm, (stellate-) campanulate, chartaceous to membranaceous, white, green, or purplish, the tube 3-4 mm, the lobes 7-19 x 3-5 mm, narrowly triangular, acute at apices, sparsely to densely pubescent-pilose abaxially, glabrous to sparsely pubescent adaxially, the margin tomentose to ciliate with hairs up to 1 mm long. Anther thecae 7-8 x 1.5-2 mm, lanceolate, connivent, yellow, white, or purplish, the pores directed abaxially; connective 8-9 mm x 2-3 mm wide at base, broad at base, abruptly constricted 1-2 mm above base, abaxially slightly shorter than thecae at apex, exceeding them at base by 1 mm, absent adaxially, purple. Ovary glabrous; style 6-9 x 0.5-1 mm, about equal to or exserted ca. 1-2 mm beyond stamens, cylindrical, glabrous; stigma truncate.
Fruits 2.5-5.5 x 1-3 cm, ellipsoidal, somewhat flattened laterally, obtuse or somewhat acute at apex, light green with dark green longitudinal stripes, glabrous (occasionally minutely puberulent); stone cell aggregates smooth, oval, ca. 3-5 x 3 mm.
Seeds ca. 2-4 x 1-3 mm, flattened, reticulate.
