Description:
Description - Tree 10 m tall, the branchlets densely ferruginous-strigulose; stipules deciduous to persistent, 1-1.5 mm long, narrowly triangular, densely strigulose externally; petioles 15-20 mm long, minutely strigulose, stipellate apically; rachis 9.5-14.5 cm long, stipellate at each pair of leaflets, minutely strigulose; leaflets 6- or 7-jugate, the petiolules 1-1.5 mm long, minutely strigulose, the blades oblong-lanceolate, ca 5 cm long and 1.5 cm wide, the basal ones smaller, all the leaflets rounded-obtuse basally, acuminate apically, glabrous on the upper surface, minutely strigulose and discolorous beneath, the venation obscure, the costa strongly impressed on the upper surface and salient beneath, the primary veins plane on both surfaces; infrutescence racemose, ramuligerous, 7.5-15 cm long, the axis minutely strigulose densely, the bracts persistent, narrowly ovate, 2 mm long, minutely strigulose externally, the bracteoles lacking; pedicels 5-6 mm long, densely strigulose; calyx segments 4, persistent; petal lacking (?); stamens and gynoecium not seen; fruit 20-25 mm long, 10-12 mm diameter, oval in outline, minutely strigulose, 1-seeded, the stipe 4-5 mm long; seeds 18-23 mm long, oval, black, nitid.

Discussion:
Although the flowers are not known, this species is very suggestive of S. sericea and for this reason alone it is placed among the species characterized by apetalous flowers. From S. sericea it differs in the glabrous inner surface of the calyx; from other related species it is separable by either the vestiture or the number of pairs of leaflets.
