Description:Species Description - Tree 10 m tall, stems 8-10 cm in diam. Distal portion of stems terete, blackish brown, puberulent, smooth. Leaves paripinnate; distal process minute, conical; leaflets 6-8, opposite or alternate, elliptic, coriaceous, 13.5-20 × 4.5-6.5 cm, glabrous, glossy on adaxial surface, midvein yellowish, prominent on abaxial surface, tertiary veins reticulate, the apex acute or acuminate, the base inequilateral, one side obtuse the other acute, narrowing into the petiolule; petiolules 10-20 mm long, with a conical, reddish brown, pulvinate base; rachis 20 cm long or longer, terete, puberulent, dark reddish brown, dull; petioles 9-17 cm long, pulvinate at base. Thyrses panicle-shaped, 17-33 cm long, axillary; cataphylls clustered, axillary, acicular, ca. 2 mm long, puberulent; axes terete, striate, minutely pubescent; bracts persistent, deltate, 0.6-1 mm long, minutely pubescent; dichasia compound; peduncles ca. 2-2.5 mm long, flattened, minutely pubescent; pedicels 1.7-2.2 mm long, articulate at the middle, minutely pubescent. Calyx green, 2.5-3 mm long, minutely pubescent, the sepals 1.2-1.6 mm long, deltate, concave; petals reflexed at anthesis, oblong-elliptic, 3.5-4 mm long, white, sericeous on abaxial surface, papillate on adaxial surface, the base cuneate; appendages deltate, as long as the petals, adaxially sericeous-tomentose, abaxially sericeous on upper half; disc 5-lobed, sericeous; stamens 6-8, the filaments pilose, slightly unequal, 2-2.3 mm long, the anthers elliptic, 1.3-1.7 mm long, apiculate at apex. Pistillate flowers, fruits and seeds unknown.
A T. guianensi Aublet foliolis paucis, petalis minoribus, sericeis et filamentis pilosis differt.
Discussion:Talisia douradensis resembles T. guianensis in general aspect. However, T. douradensis differs by its leaves with fewer leaflets (6-8 vs. 16-22) and puberulent rachis (vs. glabrous); its deltate, minutely pubescent (vs. subulate, appressed-pubescent) bracts and bracteoles; minutely pubescent calyx with deltate sepals (vs. puberulent with ovate sepals); abaxially sericeous, 3.5-4 mm long petals (vs. abaxially glabrous, 6-7.5 mm long); sericeous disc (vs. glabrous or hispidulose); and stamens with pilose (vs. glabrous) filaments. This species is easily distinguished by the elongated petiolules and abaxially sericeous petals. The specific epithet refers to Monte Dourado, the locality where the species was collected. Phenology. Collected in flower in October.
