Description:

Species Description - Treelet or tree, with sympodial branching, 2-8 (30) m tall; trunk to 8 (35) cm in diam.; bark grayish to dark brown, smooth or lenticellate. Stems nearly terete, striate, glabrous, becoming lenticellate, sometimes hollow in the center and inhabited by ants. Leaves paripinnate, spirally arranged on distal portion of stem(s); distal process woody, truncate, early deciduous, 2-4 mm long; leaflets (2) 8-16 (32), opposite or alternate, oblong, narrow-oblong, elliptic, narrow-elliptic, obovate, oblanceolate or less often falcate, chartaceous to coriaceous, 14-36(-61) × 3.5-10.4 (-21) cm, flattened or less often bullate, the adaxial surface glabrous, with prominent midvein but impressed secondaries and tertiaries, the abaxial surface glabrous or less often puberulent, with prominent brochidodromus venation, the secondary veins alternate, forming a prominent intramarginal vein, tertiary venation reticulate, the apex long-acuminate or less often obtuse, the base asymmetrical to very strongly asymmetrical, one side obtuse the other cuneate or attenuate, the margins entire or undulate, revolute or slightly so; petiolules enlarged, cylindrical or bulbous (longer than wider), 7-12 mm long, glabrous or puberulous, adaxially canaliculate; rachis glabrous or puberulous, (7.5-) 21-41 cm long, slightly flattened dorsiventrally, sharply angled toward the margins on distal portion, nearly terete on proximal portion; petioles 14-41 (56) cm long, terete, striate, glabrous, less often lenticellate, enlarged at base. Thyrses panicle-shaped, 30-60 cm long, terminal or axillary on distal part of branches; cataphylls acicular, 5-15 mm long, appressed-pubescent; axes slightly angled, striate or sulcate, puberulent to tomentose; bracts and bracteoles deltate, puberulent to tomentose, ca. 0.5 mm long; dichasia compound; peduncle 1-2 mm long; pedicels < 1 mm long, articulate at the middle, with the same indumentum as the axis. Flowers buds angular-ovoid. Calyx 2-3 mm long, light green, puberulent to tomentose, the sepals 1-1.2 mm long, oblong-rounded or ovate, slightly concave; petals white, 4.5-7 mm long, lanceolate or less often oblong, glabrous or adaxially papillate, obtuse or rounded at apex, cuneate at base, the margins usually ciliate on lower portion; appendage as long as the petal or slightly shorter, long deltate, abaxially papillate or less often glabrous, adaxially hirsute above the base; disc 5-lobed, puberulent, tomentose or sparsely hirsute, 0.7-1 mm tall; stamens 5, the filaments of equal length, pilose to glabrous, 2.2-2.5 mm long, slightly flattened, the anthers oblong to lanceolate, 1.3-2.2 mm long, apiculate at apex; ovary tomentose, conical, the stigma elongate-capitate, ferruginous-papillate. Fruits yellow to orange-yellow at maturity, ellipsoid or ovoid-ellipsoid, apiculate, 1.8-3 cm long, glabrescent, minutely rugulate, the pericarp woody, 1-3 mm thick, the endocarp smooth, sparsely tuberculate and sparsely appressed or woolly-pubescent. Seed 1(2) per fruit, ellipsoid, the testa woody, with a thin, fleshy, upper layer. Embryo with cotyledons lying dorsiventrally to obliquely dorsiventrally over each other, both cotyledons of similar size or the lower one larger than the upper one.

Discussion:

Talisia nervosa can be distinguished by its flowers (5-stamens, pilose filaments and puberulent to hispidulose disc), fruits with pubescent endocarp and leaflets with strong intramarginal veins. The specific epithet refers to the conspicuous venation of leaflets.

From Nicaragua south to Colombia, Venezuela, Ecuador, Peru, and French Guiana, in understory of wet, non-flooded forest.

Phenology. Flowers from October to May, and fruits throughout the year.
