Acacia storyi Tindale, Proc. Linn. Soc. New South Wales ser. 2, 91: 147 (1966)

Shrub or tree to 6 m high; d.b.h. 15–23 cm; canopy sparse. Bark smooth, grey-green. Branchlets dark purplish red, bluish or purple, sometimes pruinose, glabrous; ridges inconspicuous. Young foliage-tips cream-coloured. Leaves subcoriaceous, dark green; petiole above pulvinus (0.8–) 1.2–2.3 cm long, flattened vertically, with 1 or 2 (–3) glands; rachis 4–11 cm long, flattened vertically, with an orbicular or oblong, glabrous or slightly pubescent gland at base of all or most pairs of pinnae, with 1 or 2 (–4) sometimes contiguous, interjugary glands between some or all pairs of pinnae; pinnae 8–18 pairs, 2–6 (–8) cm long, the basal pair(s) often caducous leaving inconspicuous scars; pinnules 26–92 pairs, oblong to cultrate, 1.5–4 mm long, 0.4–0.6 (–0.8) mm wide, ciliolate otherwise glabrous, apex broadly rounded to subacute. Inflorescences in axillary racemes, or terminal or axillary false-panicles. Heads 14–20-flowered, cream-coloured or pale yellow. Pods straight-sided to slightly or irregularly more deeply constricted between seeds , 2.5–11 cm long, 8–12 mm wide, coriaceous, dark red-brown or blue-black, sometimes pruinose, glabrous.

Occurs on the Blackdown Tableland and adjacent, lower land on W side, Qld. Grows on sandstone plateaux, in open forest. Other acacias confined to the Blackdown Tableland include A. gittinsii and A. hendersonii . Flowers Apr.–Aug.; fruits Aug., Sept., Dec.

Closely related to Acacia filicifolia which also has fern-like leaves, fine, narrow, closely spaced pinnules, numerous interjugary glands on the rachises, and pruinose, glabrous, broad, rather flat pods. It differs from A. filicifolia in being mostly glabrous, having shorter pinnules and cream-coloured or pale yellow inflorescences. Acacia storyi is also closely related to A. olsenii .

Acacia storyi , A. deanei subsp. deanei , A. glaucocarpa and A. pedleyi are the most northerly occurring species in sect. Botrycephalae .
