Acacia littorea Maslin, Nuytsia 2: 311; 312, fig. 16 & 330, fig. 24 (1978)
Dense shrub 1–2 m high. Branchlets prominently ribbed, glabrous. Stipules caducous. Phyllodes rather crowded, ascending, obtriangular to obdeltate with a prominent gland-bearing angle on adaxial margin above the middle, sometimes asymmetrically trapeziform with 2 gland-bearing angles, with adaxial proximal margin contiguous with branchlet, obliquely truncate, 7–17 mm long, 5–15 mm wide, l:w = 1–2, sometimes larger, pungent, glabrous; midrib near lower margin. Inflorescences extremely reduced 1- (3–or 4–) headed racemes with axes to c. 0.5 mm long; peduncles 6–12 mm long, glabrous; heads globular, 8–15-flowered, pale yellow. Flowers 4-merous; sepals united to near apex, with lobes broadly triangular. Pods linear, curved, to 6 cm long, 2.5–3 mm wide, crustaceous, blackish, glabrous or subglabrous; margins thick, yellowish. Seeds longitudinal, oblong, 2.5–3 mm long, shiny, brown; aril scarcely clavate.
Coastal areas from near Busselton E to Bremer Bay, also on Rottnest Is., south-western W.A. Grows on coastal dunes in deep sand, commonly in heath; often locally abundant. Flowers Aug.- Dec.
Possibly better treated as a subspecies of A. truncata . See B.R.Maslin, Nuytsia 2: 311–321 (1978), for discussion.
