Morphology General Habit
Tree 10–25 m. high; bark on trunk lemon-coloured to greenish-yellow.
Morphology Branches
Young branchlets brown to plum-coloured, almost glabrous and with some sessile reddish glands; twigs showing conspicuous pale yellow powdery bark.
Morphology Leaves Stipules
Stipules spinescent, straight or almost so, varying in length, up to 7 (–8.5) cm. long; “ant-galls” and other prickles absent.
Morphology Leaves
Leaves:rhachis (2.5–)3–7 cm. long, glabrous to sparingly pubescent; pinnae 3–6(–8) pairs (on juvenile shoots sometimes to 10 pairs) per leaf; leaflets rather numerous, 2.5–6.5 mm. long, 0.75–1.75 mm. wide; lateral nerves invisible beneath.
Morphology Reproductive morphology Flowers
Flowers varying from white or purplish to yellow or golden (see note below).
Morphology Reproductive morphology Inflorescences Peduncles
Peduncles sparingly (rarely rather densely) pubescent to subglabrous, and glandular below and sometimes also above the involucel, usually (at least) on abbreviated lateral shoots whose axes do not elongate and are represented by clustered scales, the peduncles thus appearing to be in lateral fascicles on the older often yellow-barked twigs whose leaves have fallen.
Morphology Reproductive morphology Inflorescences Bracteoles
Involucel conspicuous, 3–3.5 mm. long, near base of to about half-way up peduncle.
Morphology Reproductive morphology Flowers Calyx
Calyx 1–1.5 mm. long.
Morphology Reproductive morphology Fruits
Pods (Fig. 16/36, p. 67) indehiscent, linear-oblong, straight or slightly curved, ± moniliform with segments mostly longer than wide, often breaking up, pale brown or brown, reticulate-venose, eglandular or sparingly glandular, (3–) 4–13.5 cm. long, 0.7–1.4 cm. wide.
Morphology Reproductive morphology Seeds
Seeds olive to blackish-olive, smooth or nearly so, subcircular to elliptic, compressed, 4.5–5.5 mm. long, 3.5–4 mm. wide; areole 3–3.5 mm. long, 2 mm. wide.
