Description:  "A tropical American tree that can grow over 100 feet tall.  It is easily recognized by its leaves, which have as many as 50 pairs of relatively small (0.25-2 inch long), linear-elliptic leaflets and a gland between the lower 2-4 pairs of leaflets.  The pods are flat and 2-6 inches long" (Staples & Herbst, 2005; p. 326).

Subsp. lindleyana var. lindleyana:  "Tree 9-11 m. high (up to 25 m. where indigenous).  The larger leaves are up to 30 cm long, with 16-36 (-46) pairs of leaflets gradually decrescent toward base and apex of leaf, and the largest leaflets are up to 46 x 13 mm.  The flowers have greenish to yellow sepals, the largest (inner) one up to 7.5 mm long, and the yellow petals are as long as 16-26 mm."  Subspecies lindleyana differs from subsp. multijuga in having its stipules setiform, not more than 0.6 mm broad at base, and with plane margins (rather than, as in subsp. multijuga, asymmetrically dilated and 0.8-2.5 mm broad at base and undulately crimped or folded" (Smith, 1985; p. 115).
