Acacia leptostachya

Acacia leptostachya is a shrub or tree that typically grows to a height of 0.5–6 m (1 ft 8 in – 19 ft 8 in) and usually has soft hairs pressed against the surface and young shoots resinous but not sticky. Its phyllodes are narrowly elliptic to lance-shaped, sometimes almost linear, 40–90 mm (1.6–3.5 in) long and 2–12 mm (0.079–0.472 in) wide and contain many fine, rather closely packed veins, with two or three more prominent. The flowers are golden yellow and borne in two spikes 20–40 mm (0.79–1.57 in) long on a peduncle 1–3 mm (0.039–0.118 in) long. Flowering occurs in August and September, and the pods are linear, up to 60 mm (2.4 in) long, 2–9 mm (0.079–0.354 in) wide, firmly papery to thinly leathery glabrous, and raised over the seeds. The seeds are oblong, 2.7–4 mm (0.11–0.16 in) long and shiny brown with a small aril.

This species of wattle grows in deep sand on sandstone or granite in eucalypt woodland, open forest or Triodia hummock grassland from the central-eastern parts of Cape York Peninsula near Coen through coastal and inland districts ae far south as Maryborough and south of Charleville. It is also found near Riversleigh Station, about 200 km (120 mi) north-west of Mount Isa.

This species of shrub or tree grows well a full sun position in dry well drained soils. It can be propagated from seed after seeds are scarified or treated with boiling water.
