Acacia citriodora Tindale & D.Keith (ms)
Semiprostrate, flat-topped, resinous shrub to 2 m high, branching from base. Bark fissured, grey-brown. Branchlets slender and angular near apices, light brown or light red-brown, glabrous, tuberculate; ridges pale coloured. Phyllodes linear-elliptic, sometimes basally tapered, flat, slightly upcurved to ±straight, 1.2–5.5 cm long, 1.5–5 mm wide, thick, glabrous, the minor veins sunken, obscure, sometimes with 2 longitudinal semiprominent veins; glands 1–3, minute, 4–22 mm above pulvinus. Spikes 0.9–3 cm long, golden. Flowers 5-merous; calyx 0.5–1.2 mm long, cut to 1/2–4/5, glabrous; corolla 1–2 mm long, cut to c. 1/2, glabrous; ovary glabrous or scurfy. Pods erect, linear-oblanceolate, basally tapered, flat, straight-sided, 2.5–5 cm long, woody, almost glabrous, obliquely veined, opening elastically from apex; margins thickly tuberculate. Seeds oblique, oblong-elliptic, 3.2–5 mm long, brown or olive-brown, with often darker, open areole; funicle-aril narrowly conical.
Occurs in arid tropical Australia, in the Halls Creek-Margaret R. area and N coast between Port Hedland and Anna Plains, W.A., the Tanami district, N.T. and mainly in the Mount Isa-Camooweal area, Qld. Grows in gravelly, red or brown, skeletal soils on quartzite or laterite, on ridges or plains in spinifex-shrubland or savannah eucalypt woodland. Flowers May–Oct.
Allied to A. hilliana from which it is distinguished by its flat, linear-elliptic phyllodes with 1–3 marginal glands, paler pods and larger seeds. Further fruiting material is needed.
