Description
Species Description - Treelet 1.5 to 4 m tall, sometimes with few upright branches; trunk ca. 2.5 cm in diam. Stems terete, smooth or minutely lenticellate, puberulent or pubescent. Leaves paripinnate; distal process acicular, ca. 3 mm long, early deciduous, leaving a truncate base; leaflets (4) 6-8 (10), alternate to opposite, lanceolate to elliptic-lanceolate, 6-31 × 2.4-10 cm, coriaceous, glabrous except for the abaxially, minutely pilose midvein, the venation brochidodromus with a slightly conspicuous marginal loop, plane on adaxial surface, prominent on abaxial surface, tertiary veins reticulate, the margins sometimes revolute, the apex long-acuminate, acuminate or less often acute, the base acute-obtuse, sometimes unequal; petiolules pulvinate, 0.5-1 cm long, minutely pubescent; rachis 3-22 cm long, terete, minutely pubescent, glabrescent; petioles 7.5-15 cm long, gradually thickened toward base. Thyrses panicle-shaped, sometimes fasciculate, terminal or supra-axillary; cataphylls flattened-acicular or sub-pinnate, 1.7-2 cm long, tomentose; axes to 20 cm long, terete, ferruginous-tomentose; bracts triangular, persistent, 1.5-2 mm long; dichasia simple or compound, sessile or shortly pedunculate; pedicels to 1.5 mm long, articulate at the apex. Calyx 2.5-3 mm long, tomentulose, the sepals 1-1.5 mm long, oblong, concave to slightly keeled, rounded at apex; petals oblanceolate to elliptic, 4-4.5 mm long, reflexed at anthesis, papillate on adaxial surface, glabrous on abaxial surface except for a few hairs near the base, the apex sometimes slightly retuse, the base attenuate; appendages slightly shorter than petals, oblong, erect, entire or bifid at apex, sericeous-tomentose on both surfaces; disc cup-shaped, 5-lobed, hirsute, ca. 0.8 mm tall; stamens 8, the filaments of equal length or slightly unequal, 4-5 mm long, minutely pilose, the anthers 1.2-1.6 mm long, oblong-lanceolate, glabrous, apiculate at apex; ovary nearly conical, tomentose, the stigma obconical to capitate. Fruits ellipsoid to ovoid, glabrous, (trigono-obovoid and appressed-pubescent when young), turning from green to yellow, 1.7-2.5 (3) cm long, minutely granulate to smooth, apiculate, the pericarp 0.7-0.8 mm thick, the endocarp granulate, glabrous. Seeds ellipsoid, with fleshy testa; cotyledons superimposed horizontally or obliquely, the lower one slightly larger to twice as large as the upper one, sometimes poorly differentiated in the area adjacent to the radicle.

Discussion
Two collections with different dates and localities were distributed under Spruce 1992 (both annotated by Radlkofer). The first is from Tarumã-Agu creek, collected in February of 1855. The second collection is from Uanauca-Gapó and was collected in December of 1851.1 have designated the 1855 collections as lectotypes and isolectotypes because there are more duplicates available for this collection than for the 1851 collection. The specific epithet refers to the characteristic leaflets with acute or acuminate apices.
The seeds have a fleshy, edible coat, consumed by the local people.Phenology. Collected in flower from December to February and in August; known to fruit in January, May and August.
