Branches sulcate, tomentulose, becoming terete and lenticellate with age. Leaves paripinnate or imparipinnate; terminal process truncate, ca. 2 mm long; leaflets 5-8, alternate or subopposite, oblong, elliptic, lanceolate, or nearly obovate, chartaceous to subcoriaceous, 4-9(14) × 1.5-3.4(4.5) cm, discolorous, the venation brochidodromus, tertiary veins finely reticulate, the adaxial surface glabrous, often with scattered, raised, conical insect galls, or necrotic, round spots, with impressed midvein and prominulous secondaries, the abaxial surface usually drying brownish, minutely puberulent, especially along the prominent midvein, secondary veins inconspicuous or less often prominulous, the apex obtuse, retuse, sometimes nearly acuminate, the base obtuse or acute, decurrent onto the elongated petiolule; petiolules nearly cylindrical, slender, glabrous, 3-7 mm long, striate, adaxially canaliculate; rachis 3.5-7(11) cm long, puberulent, terete, striate; petioles 2.5-5.5 cm long, puberulent, slightly flattened adaxially, striate, minutely lenticellate, slightly enlarged at base. Thyrses panicle-shaped, 9-25 cm long, terminal on branches; cataphylls wanting, the axes obusely angled, striate, minutely, velvety pubescent; bracts and bracteoles triangular, tomentose, ca. 0.5 mm long, early deciduous; dichasia simple, nearly sessile; pedicels 1.5-2 mm long, ferruginous-tomentulose, articulate at the middle or below. Calyx pale green, 2.53 mm long, minutely tomentose or pubescent, the sepals free to the base, ovate or deltate, concave; petals white, rhombo-ovate or ovate, ca. 3 mm long, abaxially appressed-pubescent at base, adaxially glabrous, cuneate at base, obtuse at apex; appendages as long as the petals, ovate-deltate, fused at base to the basal margins of the petal to form a pocket, adaxially white-sericeous above the base, abaxially glabrous; disc annular, crenate, tomentose, 0.9 mm tall; stamens 8, the filaments of unequal lengths, glabrous or puberulent, the anthers ovoid, 0.5-0.75 mm long, apiculate; ovary ovoid, tomentose, the stigma trigonous-capitate, papillate. Fruit ellipsoid to ovoid, ca. 2 cm long, densely appressed ferruginous pubescent, the pericarp woody, ca. 1 mm thick, the endocarp sparsely woolly-pubescent. Seed solitary, with thin, dry testa. Embryo with cotyledons of similar size, lying transverse over each other.

Discussion
The specific epithet seems to refer to the Simaba-like (Simaroubaceae) appearance of the leaves.
