Description:
Description - Shrub or weak tree 2-5 m tall, the branchlets densely rusty-pilose; stipules persistent, 2-3 mm long, linear or linear-lanceolate, strigulose externally, glabrous within; leaves unifoliolate, the petiole 2-6 mm long, densely pilose, apically stipellate, the stipels 1-1.5 mm long, the petiolules lacking, the blades 8-14.5 cm long, 4-7 cm wide, elliptic to broadly elliptic, the base rounded, subcordate, the apex acuminate with the tip obtuse and retuse, pilose or pilosulose on the costa on the upper surface of the blades, pilose or flexuose-pilose on the lower surface, the venation prominulous on the upper surface, prominent beneath, the costa and the primary vein-branches plane on the upper surface of the leaflets, salient beneath; inflorescence axillary, the axes densely pilose, 3-7 cm long, the bracts deciduous to persistent, ca 2 mm long, pilose, the bracteoles persistent, 2-3 mm long, linear-lanceolate, strigulose externally, glabrous within; pedicels 13-22 mm long, densely pilose; buds ovate in outline, ca 12 mm long and 10 mm diameter, pilose; calyx segments 3 or 4, persistent with the fruit, pilose densely externally, glabrous within; petal white, sparingly villose externally, glabrous within, the blade oblate, ca 2 cm long and 2.5 cm wide; larger stamens 5, glabrous, the filaments ca 18 mm long, the anthers narrowly oblong, ca 5 mm long and 1.5 mm wide, the smaller stamens glabrous, the filaments ca 8.5 mm long, the anthers oval, ca 1 mm long; gynoecium glabrous, the stigma punctiform, the style 3-5 mm long, the ovary elliptic, ca 9 mm long and 3.5 mm wide, the gynophore 14-16 mm long; fruits ovate, elliptic, or ovate-oblong in outline, "vermilion" (fide Spruce), 25-30 mm long, 12-17 mm diameter, the style persistent as a beak 3-6 mm long, the stipe 16-20 mm long.

Discussion:
There is some evidence to relate this species to S. fimbriata but the latter has the calyx segments pubescent on the inner surface and the ovary pubescent on one suture. From S. eriocarpa, an even closer relative, the present species differs in its glabrous gynoecium.
