Characteristics

Shrub to 2 m high, erect, glabrous, resinous, sometimes scurfy, usually branching near base. Bark smooth, dark grey to black. Branchlets angular towards apices often with resin-crenulated ridges. Phyllodes elliptic to narrowly elliptic (sometimes slightly wider below or above middle), oblique, curved and slightly sigmoid, (0.6-) 1-2 cm long, 4-9 mm wide, with an oblique short mucro (the apices of young phyllodes often dilated, pellucid and appear as if filled with gummy or resinous fluid, fide protologue), thinly coriaceous, sometimes ±glaucous, with 3 ±visible main nerves; minor nerves longitudinally obscure, finely longitudinally wrinkled; gland basal, minute, to 1.5 mm above pulvinus. Peduncles (5-) 13-22 cm long, 0.5-0.7 mm diam. Heads 5-8 mm diam., 20-50-flowered, medium golden or bright yellow, sometimes light golden; buds slightly spreading; bracteoles mostly with short irregularly triangular ±peltate lamina. Flowers 5-merous; calyx cupular, 1-1.3 mm long, dissected to 1/8-1/6; corolla 2-2.5 mm long, dissected to 1/3-1/2; petals with prominent midrib. Pods erect, narrowly oblanceolate to oblanceolate, basally tapered, 2-5.5 cm long, (4-) 5-10 mm wide, thinly woody and brittle, brown to blackish, obliquely nerved, opening elastically from apex. Seeds oblique, oblong, 3-5.8 mm long, brown; pleurogram with pale halo; funicle-aril narrowly turbinate.
