Description:  "Shrubs, small trees, or trees, 7-20 (-40) m tall. Young parts generally puberulent; branchlets reddish brown when dry. Leaves 12-20 cm; stipules early caducous, linear; rachis and petiole puberulent, with a long, ovoid gland on rachis between lowest pair of leaflets (often early caducous); leaflets 10-26 (-50) pairs, linear-oblong or oblong, 1.2-4 x 0.6-0.8 cm, both surfaces puberulent or adaxially glabrous, apex obtusely rounded, mucronate, slightly oblique. Racemes several, arranged in a terminal, leafy panicle 10-20 (-40) cm; peduncle and pedicels puberulent. Flowers 2.5-4 cm in diameter; bracts ovate, ca. 2 mm, tomentose. Sepals greenish yellow when mature, slightly unequal, 5-6 mm. Petals yellow, ovate-oblong, 1-2(-3) cm, glabrous. Fertile stamens 7, 3 larger, with filament ca. 10 mm and anthers 6-7 mm, staminodes 3, tiny. Ovary linear, glabrous. Legume dark brown, flat, broadly linear, obtuse. Seeds 30-60, flattened, ca. 6 mm"  (Flora of China online).

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).
