Acacia leprosa (Leper Wattle, Cinnamon Wattle)

Erect or spreading shrub 1–6 m high, sometimes a tree to 10 m high; bark smooth, greyish; branchlets terete or angled towards extremities, resinous, glabrous except for appressed-hairy ridges. The raised fine ribs are yellowish to light brown or dark red-brown while the wider regions between them are more or less the same colour or darker than the ribs and sometimes have a thin veneer of resin.

Phyllodes usually elliptic or narrowly elliptic to lanceolate, straight to slightly curved, usually 5–14 cm long and 5–15 (-30) mm wide, glabrous or with appressed hairs on margins and veins, dotted with resin glands, with 1 or 2 longitudinal veins (when 2-veined the veins are of equal prominence or the upper (adaxial) one is more pronounced); lateral veins when present fine, openly anastomosing, often distally coalescing to form a fine, uneven intra-marginal vein on one or both sides of the phyllode; apex mostly acute to acuminate; 1 gland 0–8 mm above pulvinus; pulvinus 0.5–2 mm long.

Inflorescences simple, 1–6 in axil of phyllodes or rarely on an axis (rudimentary raceme) 1–3 mm long; peduncles 4–10 mm long, glabrous or hairy; heads globose, 20–40-flowered, 5–10 mm diam., pale or bright yellow.

Pods straight to slightly curved, ± straight-sided to barely constricted between seeds, sometimes more deeply constricted between some seeds, 4–8 cm long, 3–5 mm wide, firmly papery to thinly leathery, glabrous or ± hairy especially along margins; seeds longitudinal; funicle expanded towards seed.
