Description
Species Description - Trees of unknown stature, the young branchlets, lf-axes, and units of inflorescence densely brownish silky-velutinous overall, only the ventral face of lfts glabrous. Stipules narrowly elliptic, ±3 mm, ephemeral. Lf-formula ii/4-6; lf-stks 5-7.6 cm, the petiole 3-4 cm, the one interpinnal segment 2-3.5 cm; a nectary between each pair of pinnae mounded-hemispherical but crumpled when dry, ±1.2-2 mm diam, nigrescent; rachis of distal pinnae 3.5-7 cm, charged at base with a pair of subulate paraphyllidia, the longer interfoliolar segments 11-14 mm; lft- pulvinules 1-1.4 mm; lfts subrhombic-oblong from inequilateral base, attaining ±20 x 9 mm but perhaps longer when fully mature, all faintly pinnate-veined. Peduncles solitary or 2-3-nate in axil of coevally expanding lvs, 3-5 cm; capitula incipiently umbelliform, the peripheral fls shortly pedicellate, the terminal fl sessile; perianth in bud resembling that of A. floribunda', ovary truncate. Pods unknown.

Discussion
The specimen cited has flush foliage and flowers ready to expand; it is not referable to any known Amazonian species of Abarema. The flowers are reminiscent of those of sympatric A. floribunda at the same stage of immaturity, but the leaf-formula is significantly lower and the young leaflets are densely brown-velvety dorsally. The specimen is from tree no. 1860 in Reserva of Projeto Dinámica Biolôgica de Fragmentos Forestais at ±2°19/S, 60°05'W.
