Description
Species Description - Treelet to 3 (7) m tall, unbranched or with a few upright branches on distal portion, these with determinate growth due to a terminal inflorescence; trunk to 5 cm in diam., bark grayish, smooth. Stems terete, minutely lenticellate, puberulent, glabrescent. Leaves paripinnate or less often imparipinnate; distal process acicular, early deciduous leaving a truncate base 2-3 mm long; leaflets 8-16 (26), alternate or subopposite, oblong-elliptic or elliptic, (5) 7.2-21 (27.5) × (2.5-) 3-5.5 (-7.9) cm, chartaceous to subcoriaceous, glabrous, the adaxial surface with a prominulous midvein, and slightly sunken secondary veins, the abaxial surface with prominent, puberulent veins, the venation brochidodromus, with secondary veins alternate or subopposite, arching, tertiary veins reticulate, the margins undulate, the apex acuminate to long-acuminate, the base oblique, one side obtuse the other attenuate, tapering on to the petiolule, distal leaflets usually larger than the proximal ones; petiolules pulvinate at base, canaliculate along adaxial surface, 3.5-10 mm long, glabrous to puberulent, the pulvinus obconical to cylindrical, 3.5-5 mm long; rachis (12) 18-52 cm long, pentagonous, bisulcate, obtusely to narrowly angled, nearly terete toward base, glabrous or puberulent, smooth; petioles 10-17 (27) cm long, terete, pulvinate at base. Thyrses panicle-shaped, terminal or axillary on distal portion of main stem and branches, or less often cauliflorous; cataphylls acicular, clustered, supra-axillary, 5-12 mm long, persistent or deciduous; axes (13.5-) 19-25 (-68) cm long, the secondary branches 6-10 (-21) cm long, angular, usually sulcate, reddish tinged, sparsely to densely covered with minute, whitish hairs; bracts ovate, persistent, ca. 0.5 mm long; dichasia compound, sessile or shortly pedunculate; pedicels 0.5-1 mm long, articulate at the middle. Calyx 1-1.8 mm long, puberulent to pubescent, the sepals 0.5-0.6 mm long, ovate, concave, rounded at apex; petals white, oblong, truncate at base, 2.5-3.6 (-4.2) mm long, reflexed at anthesis, adaxially glabrous or papillate, abaxially appressed-pubescent, especially on lower half, the apex rounded, the base cuneate-obtuse; appendages as long as or a little shorter than the petals, lanceolate, erect, entire at apex, adaxially sericeous-tomentose, abaxially sparsely sericeous-tomentose or glabrous; disc annular, 5-lobed, pubescent to tomentose, 0.4-0.5 mm tall; stamens 5 (6), the filaments of equal length, 1.5-2.2 mm long, pilose, the anthers 1.1-1.3 mm long, oblong, glabrous, apiculate at apex; ovary ovoid, densely ferruginous-tomentose, the stigma capitate. Fruits 1-2-seeded, ellipsoid to obovoid, turning from green to orange-yellow, sparsely pubescent, glabrescent, granulate, 1.5-2.1(-2.5) cm long, rounded at apex, shortly apiculate, the pericarp 0.4-1.2 mm thick, the endocarp granulate, glabrous. Seeds ellipsoid, to 1.5 cm long, with fleshy, edible, cream testa; cotyledons superimposed, of equal size.

Discussion
Talisia carinata seems to be closely related to T. sylvatica. However, T. carinata differs from T. sylvatica by: secondary veins 8-11 (vs. 11-20); abaxial leaf surface without granules (vs. punctate or granulate); venation and leaf rachis glabrous (vs. puberulent); and petals pubescent sericeous adaxially (vs. glabrous). In addition, Talisia sylvatica on the average, has larger leaflets and fewer per leaf than T. carinata. A few specimens of T. carinata with large leaflets resemble T. acutifolia, however, T. carinata differs by its angled leaf rachis (vs. terete), chartaceous and more numerous leaflets (vs. coriaceous and fewer leaflets), and by its flowers with abaxially appressed-pubescent petals (vs. glabrous), and 5 stamens (vs. 8).
The specific epithet refers to the abaxially keeled midvein of the leaflets.Phenology. Known to flower from May to October and to fruit all year round.
