Acacia julifera Benth., London J. Bot . 1: 374 (1842)
Tree to c. 7.5 m high or straggly shrub to c. 3 m. Bark rough, fibrous, reddish, greyish brown or black. Branchlets slightly flattened towards apices, very slender, reddish or purplish brown, tomentose, later glabrous. Juvenile phyllodes elliptic, oblique, straight or slightly falcate, densely tomentose. Mature phyllodes narrowly lanceolate, gradually tapered to base, flat, falcate, 7–19 cm long, 5–33 mm wide, thinly coriaceous, glabrous to tomentose, with 3 prominent main nerves separate from apex to base, the minor nerves 6–9 per mm, parallel, not anastomosing, raised; gland 1, basal, inconspicuous, to 2.2 mm above pulvinus. Spikes 2–6.5 cm long, golden. Flowers 5-merous; calyx 0.5–1.2 mm long, dissected for 1/3–2/3, papillose or non-papillose, pubescent; corolla 1.1–1.8 mm long, dissected to 1/2, with papillose apex; ovary lanate. Pods linear, almost straight-sided, terete when fresh, 9.5–17 cm long, later longitudinally striate, glabrous or puberulous and papillose. Seeds longitudinal, oblong- or compressed-elliptic, 3.4–4.5 mm long, brown; pleurogram U-shaped, with yellowish halo; areole mostly paler than rest of seed.
Occurs in Qld from SE part of the Gulf of Carpentaria S through coastal and subcoastal areas. There are records, which are possibly doubtful, from the North Coast, N.S.W. Flowers Mar.–Aug.
According to L.Pedley, Austrobaileya 1: 140 (1978), A. curvinervia intergrades with A. julifera on the eastern side of its range. Related also to A. blakei , A. meiosperma and other species with spikes arranged in racemes. Specimens without fruit may be confused with A. torulosa or A. spirorbis subsp. solandri .
Details of ecology, utilisation, etc. of A. julifera are given in J.W.Turnbull (ed.), Multipurpose Austral. Trees & Shrubs 148 (1986).
There are 2 subspecies.
Mature phyllodes glabrous or subglabrous, l: w = 4–12 (–19); spikes 2–4.5 cm long; calyx lobes papillose
Mature phyllodes moderately densely silvery-pubescent, l: w = 12–20; spikes 2–6.5 cm long; calyx lobes not papillose
Acacia julifera Benth. subsp. julifera
Phyllodes c. 7–17 cm long, 5–33 mm wide, l:w c. 4–12 (–19), usually glabrous except juveniles. Spikes 2–4.5 cm long. Calyx 0.6–1.3 mm long, usually papillose at apices of lobes. Corolla c. 1.2–1.8 mm long.
Occurs in Qld from near Forsayth S to the N.S.W. border; possibly occurring on the North Coast of N.S.W. (records not verified). Grows in coastal and subcoastal country, often on sandstone, in well-drained sandy soils in open eucalypt scrub-woodland or grassland.
