|Description of Species
||Hickory Wattle is a fast-growing, medium-sized, evergreen tree with expanded petioles that serve as leaves. Trees reach 30 m in height in their native range. The stem is usually straight and topped with a symmetrical crown of relatively light limbs; the lower bole is often fluted. The bark is reddish brown and lightly furrowed. Leaves (actually phyllodes) are 10-20 cm long, 5-10 cm broad, narrowly ellipti to elliptic, prominently veined, light or dark green. The small flowers are grouped in spikes up to 6-10 cm long, singly or in pairs in the leaf axils near the branch tips. The trees flower annually, usually at the end of the rainy season or the early part of the dry season.
||Phyllodes are large up to 25 cm long and 3.5-10 cm broad, 2-5 times as long as wide, straight or straight along 1 side and curved along the other, with 4 (max. 5) main longitudinal veins, secondary veins finely anastomosing; glaborous, pulvinus 6-10 cm long. A gland (extra floral nectary) is conspicuous at the base of the phyllode.
