Description:Latin Diagnosis - A T. coriacea Radlkofer floribus minoribus et filamentis pubescentibus differt.
Species Description - Tree 10-20 m tall; trunk to 30 cm in diam. Stems terete, puberulent, striate, becoming glabrous and lenticellate with age. Leaves paripinnate; distal process truncate, minute; leaflets 4, opposite, lanceolate, oblong or ovate, 4-10 × 1.9-4.5 cm, coriaceous, glabrous on both surfaces, the venation brochidodromus, the midvein plane or sunken on adaxial surface, prominulous on abaxial surface, secondary and tertiaiy veins inconspicuous, the margins slightly undulate, the apex obtuse to long-acuminate, the base rounded or obtuse, slightly asymmetrical; petiolules canaliculate, 3-5 mm long, puberulent or glabrous; rachis 0.8-3 cm long, slightly flattened adaxially, striate, puberulent; petioles 2.5-5 cm long, slightly flattened adaxially, striate, pulvinate at base. Thyrses panicle-shaped, terminal, to 18 cm long, branches to 17 cm long; cataphylls lacking; axes angled, sulcate, puberulent; bracts early deciduous; dichasia compound, sessile; pedicels ca. 1 mm long, articulate at base. Calyx 1.5-2 mm long, tomentose, the sepals free to the base, concave, lanceolate, obtuse at apex; petals ca. 3 mm long, lanceolate, clawed at lower half, pilose abaxially at claw, the blade abaxially glabrous, adaxially papillate, the apex obtuse; appendages as long as the petals, elliptic, erect, densely sericeous, adaxially, sparsely sericeous- papillate on abaxial surface; disc 5-lobed, minutely woolly-pubescent; stamens 8, the filaments of unequal lengths, 0.7-1.8 mm long, woolly-pubescent, the anthers ca. 0.6 mm long, elliptic, glabrous, apiculate at apex. Pistillate flower unknown. Fruits ellipsoid, ferruginous-sericeous-tomentose, 2.2 cm long (immature), green, shortly apiculate at apex, the pericarp 1 mm thick, leathery, the endocarp tomentulose. Seeds ellipsoid, ca. 1.3 cm long, with fleshy testa. Embryo with cotyledons superimposed, of equal size.
Discussion:Talisia parviflora seems to be closely related to T. coriacea because of their morphological similarity. However, T. parviflora differs by: calyx 1.5-2 mm long with lanceolate sepals (vs. calyx 2.3-3.2 mm long, with ovate sepals); petals ca. 3 mm long, (vs. 3.2-5.5 mm long); filaments woolly-pubescent (vs. glabrous). The specific epithet refers to the relatively small flowers of this species. Phenology. Collected in flower during May and August, and in fruit during October.
