Description:
Species Description - Closely resembling A. filamentosa in habit, stature, indumentum, in verruciform lf-nectaries, inflorescence, and facially glabrous, eciliolate lfts, differing in lf-formula and ample lfts. Lf-formula i/1-2, the lfts 4-8 per lf; lf-stks 6-24(-55) mm; rachis of the geminate pinnae 1.5-7.5 cm, the one interfoliolar segment, when present, 1.8-5 cm; lft-pulvinules 2-3.5 x 1-1.4 mm; lfts of distal (or only) pair broadly elliptic-obovate 8-14 x 3.5-7 cm, 1.6-2.5 times as long as wide, in texture and venation like those of A. filamentosa, the anterior lfts of the smaller proximal pair often lacking. Peduncles 7-17 cm; axis of capitulum 1-2 cm; fls dimorphic, the perianth of all greenish white brunnescent, minutely puberulent distally; PERIPHERAL FLS: pedicels scarcely 1.5 mm; calyx turbinate 3.5-4.5 x 1.3-1.6 mm, the teeth 0.7-1.2 mm; corolla ±6.5 mm; androecium and gynoecium of A. filamentosa; TERMINAL FL(S): 1-3, sessile, slightly larger than the peripheral ones. Pods (few seen) of A. filamentosa but sometimes wider, ±15-19 x 1.4-2.4 cm, to 15-ovulate.
Distribution and Ecology - In restinga and Atlantic coastal forest, below 30 m, within the range of A. filamentosa but localized in coastal Bahia between 14° and 16°S (Maraú, Olivença, Una, Belmonte). — Fl. (V-)VII-IX.

Discussion:
Bentham gave no reason for equating his Pithecellobium turbinatum with P. filamentosum. Lewis (1987: 179) seemingly construed the substance, but not the name, of P. turbinatum as a form of P. filamentosum with large leaflets, but this needs demonstration.
