Common name: cinnamon wattle
Acacia leprosa var. leprosa Sieber ex DC. APNI*
Description: Erect or spreading shrub 1–4 m high.
Phyllodes elliptic to lanceolate, straight to slightly curved, usually 5–9 cm long and 3–7 mm wide, with 1 longitudinal vein (rarely an incipient second vein), glabrous or with appressed hairs on margins and midvein, dotted with resin glands, lateral veins superficially absent or very few and obscure, often coalescing to form a fine, uneven intra-marginal longitudinal vein on either side of the prominent midvein; 1 gland 0–1.5 mm above pulvinus.
Inflorescences simple, 1–6 in axil of phyllodes or rarely on an axis 2–3 mm long; peduncles 4–10 mm long, densely hairy; heads globose, 20–40-flowered, 5–10 mm diam., 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.
Distribution and occurrence: near Mittagong (Hill Top and Chain of Ponds Creek) and possibly at Mount Werong in the Blue Mountains.
Grows in eucalypt woodland or open forest, on ridge tops and steep slopes.

Distinguished from other varieties of Acacia leprosa by having narrow (not over 7 mm wide), 1-veined phyllodes. However, it appears to grade into var. graveolens around Mount Werong. Because A. leprosa var. leprosa is only known from a small number of collections, has a scattered distribution and there is limited information about population sizes it is considered to be Near Threatened (Maslin & Murphy 2009).
