Distal portion of stem nearly terete or sulcate, glabrous or puberulent, smooth. Leaves paripinnate, spirally arranged on distal portion of stem(s); distal process 5-7 mm long, acicular, deciduous leaving a truncate apex; leaflets 16-22, opposite or alternate, oblong, oblong-elliptic, or elliptic, nearly coriaceous, 8-18(44) × 2.1-6(13.5) cm, glabrous and glossy on both surfaces, midvein yellowish, prominent on abaxial surface, tertiary veins reticulate, the apex acuminate, the base inequilateral, one side obtuse the other acute, abruptly narrowing into the petiolule; petiolule 3-9 mm long, with a conical, reddish brown, pulvinate base; rachis 10-58 cm long, terete, or slightly striate on distal area, glabrous, dark reddish brown, glossy; petioles 9-38 cm long, pulvinate at base. Thyrses panicleshaped, 10-25 cm long, terminal or axillary on distal portion of branches; cataphylls clustered, supra-axillary, acicular or dendroid, 4-17 mm long, appressed-pubescent; axes reddish tinged, obtusely angled, sulcate, glabrous to puberulent; bracts persistent, subulate, 3-5 mm long, appressed-pubescent; dichasia compound; peduncles 3-5 mm long, puberulent; pedicels 1-1.5 mm long, articulate at the upper third, puberulent, reddish. Calyx reddish tinged, 2-3 mm long, puberulent, the sepals 1.5-2 mm long, ovate, concave, ciliate at margins; petals reflexed at anthesis, oblong-elliptic, 6-7.5 mm long, white, glabrous on abaxial surface, papillate on adaxial surface, the base truncate-cuneate, the margins ciliate; appendages deltate-lanceolate, as long as the petals, adaxially sericeous-tomentose, abaxially glabrous and papillate, adnate at the base of petal; disc annular, 5-lobed, glabrous or hispidulose; stamens (5)6-8, the filaments glabrous, equal or slightly unequal, 2.5-4.5 mm long, the anthers oblong, 1.3-1.5 mm long, apiculate at apex; ovary conical-trilobed, glabrous, the style elongated, appressed-pubescent, the stigma capitate, papillate. Fruit orange-yellow at maturity, ellipsoid-ovoid, apiculate, 2-2.5 cm long, glabrous, the pericarp coriaceous to woody, granulose, ca. 1 mm thick.
