Acacia lazaridis Pedley




Occurs in western areas of the Cook and Kennedy Districts, Qld, often on slopes of the Great Dividing Ra.


Shrub 0.5–2.5 m high, glabrous. Branchlets ±flattened, later angular, maroon-brown, grey when older, usually pruinose; ridges prominent. Phyllodes narrowly oblong, elliptic to narrowly ovate-elliptic, often oblique, 3–6.5 (–8) cm long, 11–22 (–27) mm wide, with retuse or rounded apex, coriaceous, stiff, green or subglaucous, with 3 prominent longitudinal main nerves (2 reaching the apex and base, the third confluent with lower margin near base) usually with 4 subprominent parallel nerves (the 2 outer not reaching apex or base); minor nerves 1–2 (–3) per mm, anastomosing; gland 1, basal, sometimes absent. Peduncles (8–) 10–20 mm long. Spikes (0.6–) 1–2 cm long, yellow. Flowers 5-merous; calyx 0.4–0.6 mm long, dissected for 1/4–2/5, glabrous or sometimes fimbriolate; corolla 1.3–1.9 mm long, dissected for 1/2–2/3, glabrous; ovary glabrous. Pods narrowly elliptic or oblanceolate to elliptic, straight-sided, straight to curved, flat, 3.4–5.8 cm long, 7–14 mm wide, often dark purplish- or reddish-brown and slightly pruinose, obliquely nerved, opening and curling back from apex; margins subprominent; seed-partitions thick. Seeds oblique, oblong-elliptic, 4–5 mm long, dark brown; areole open; funicle-aril narrowly conical.


Flowers Feb.–Nov.


Grows in gravelly red earth or shallow sandy soil, in open eucalypt forest or woodland or scrub with Acacia spp. and Triodia, on sandstone, granite or metamorphic rocks.


Qld: 7 miles [11.2 km] NE of Mirtna Stn, L.Adams 1138 (CANB, NSW); Newcastle Ra., between Forsayth and Einasleigh, L.J.Brass 1743 (BRI, MEL, NSW); 12 km N of Charters Towers turnoff, P.Hind 1052 & C.K.Ingram (BRI, CANB, K, MEL, NSW, US); Lappa, A.N.Rodd 4511 & M.Hardie (BRI, NSW, PERTH).


Acacia lazaridis is very closely related to A. limbata and their relationship needs further study to determine whether or not they should remain as separate species; also allied to A. argyraea.
