Description
Species Description - Treelet 3-6 m tall, monocaulous. Stems terete, setigerous (yellowish setae 1-1.6 mm long), intermixed with shorter, erect, simple hairs. Leaves paripinnate, spirally arranged on distal portion of stem; distal process acicular, straight, 4-6 mm long; leaflets 16-22, opposite to alternate, narrowly oblanceolate, chartaceous, 9-23.5(36) × 2-5.2 (8.1) cm, adaxial surface glabrous, with prominulous venation, the abaxial surface with prominent, setigerous primary and secondary veins, the secondary veins arcuate, forming a more or less distinctive submarginal loop, tertiary veins reticulate, the apex acuminate, the base inequilateral, one side obtuse the other attenuate, the margins entire; petiolules slightly pulvinate or entirely cylindrical, 2-10 (15) mm long, coarsely pubescent; rachis 16-36 cm long, terete to obtusely angled on distal portion, striate, setigerous, intermixed with much shorter whitish hairs, sometimes glabrescent; petioles 7-18 cm long, terete, slightly striate abaxially, with same indumentum as the rachis, enlarged at base. Thyrses panicle-shaped, ca. 35 cm long, terminal or axillary; cataphylls pinnate, or less often acicular, 1-3 cm long, setigerous; axis angled, sulcate, sericeous-setigerous, the hairs ferruginous and septate, intermixed with shorter, straight hairs; bracts and bracteoles subulate, ca. 1 mm long, pubescent, early deciduous; dichasia compound, simple or of a solitary flower due to the abortion of lateral flowers; peduncle flattened, 2-6 mm long; pedicels 1-2.5 mm long, articulate at upper third, both with same indumentum as the axis. Calyx light green, 3-4.5 mm long, puberulent and sparsely setigerous, the sepals 2-3.5 mm long, oblong, elliptic or deltate, concave, obtuse to acute at apex, ciliate at margins; petals white, 5-6 mm long, oblong to nearly spatulate, glabrous except for the abaxially tomentose base and ciliate lower margins, rounded at apex, cuneate at base; appendage as long as the petal, deltate, abaxially sparsely appressed-pubescent sometimes nearly glabrous, adaxially sericeous above the base; disc cup-shaped, 5-lobed, hispidulous at apex, ca. 1 mm tall; stamens 8, the filaments of equal or nearly equal length, sparsely pilose, ca. 3.5 mm long, the anthers oblong or oblong-lanceolate, ca. 1.5 mm long, apiculate at apex; ovary ovoid, sericeous, the stigma oblong, trigonous, short, papillate. Fruit yellow, obovoid, apiculate, ca. 3 cm long, puberulent, granulate, the pericarp woody, ca. 2 mm thick. Seeds one or two per fruit, the testa fleshy. Embryo with cotyledons superimposed, the upper one larger than the lower one.

Discussion
A photograph of a likely holotype (Eggers 14704, annotated by Radlkofer) for T. setigera., was distributed by the Field Museum (F neg. 6025) as being a Munich specimen. However, I have not been able to locate this specimen at Munich, suggesting that the specimen belonged to another herbarium. It is quite possible that this specimen may have been from Berlin, in which case it would have been destroyed. Not being able to locate this specimen, I have decided to lectotypify T. setigera with one of the remaining isotypes.
Talisia setigera seems to be closely related to T. pinnata as they share numerous morphological features. However, T. setigera can be distinguished from the latter by its setigerous branches and abaxial side of leaflets (vs. hirsutulose to tomentose branches and pilose abaxial surface of leaflets). The specific epithet refers to the setigerous indumentum in this species. <>Phenology. Collected in flower during March and in fruit in February, May, and July. -
