Acacia xerophila

Jump to a taxon beginning with the letter:

Acacia xerophila W.Fitzg., J. Western Australia Nat. Hist. Soc . 2 (1): 8 (May 1904)

Spreading, multistemmed shrub 0.3–1 m high. Branchlets glabrous or puberulous. Stipules spinose, 2–6 mm long, slender, straight or shallowly recurved. Phyllodes dimidiate, narrowly elliptic to lanceolate, sometimes obovate-oblanceolate, sometimes recurved, 1–3 cm long, 2–7 mm wide, normally acuminate, pungent, rigid, glaucous, glabrous or puberulous; adaxial margin sometimes nerve-like; midrib central or near abaxial margin. Inflorescences rudimentary 1- or 2-headed racemes with axes <0.5 mm long; peduncles 5–11 mm long, normally glabrous; heads globular, 17–30-flowered. Flowers 5-merous; sepals free to 1/2 united; petals obscurely 1-nerved. Pods (var. brevior only) sessile, narrowly oblong, to 5 cm long, 8–10 mm wide, thinly crustaceous, blackish, glabrous. Seeds (var. brevior only, slightly immature), oblique and close together, c. 5 mm long, c. 3 mm wide; aril terminal, pileiform.

Scattered from Kanandah Stn on the western edge of the Nullarbor Plain to Southern Cross, W.A.

Probably related to A. pritzeliana .

Pritzel and Fitzgerald independently described this taxon in 1904, basing their respective names on different specimens of the same collection. It is assumed that Pritzel used a specimen at B to prepare his account of A. fitzgeraldii ; this specimen appears to no longer exist although PERTH has a fragment of it. Two varieties are recognised.

Branchlets and phyllodes glabrous; phyllodes 2–3 cm long; sepals 1/4–1/2 united

var. xerophila

Branchlets and phyllodes usually puberulous; phyllodes 1–2 cm long; sepals free

var. brevior


Acacia xerophila W.Fitzg. var. xerophila

Branchlets glabrous. Phyllodes 2–3 cm long, glabrous; adaxial margin finely yet clearly 2-nerved for at least part of its length. Heads 18–30-flowered. Sepals 1/4–1/2 united; petals c. 2.1 mm long.

Scattered from Kanandah Stn on the western edge of the Nullarbor Plain to Bardoc, N of Kalgoorlie. Grows in red sand over limestone on plains (Kananda) or in rocky loam on hillsides (Bardoc).

Acacia xerophila var. brevior (E.Pritz.) Maslin, Nuytsia 12: 410 (1999)

Differing from the typical variety in the following ways. Branchlets normally puberulous. Phyllodes 1–2 cm long, usually antrorsely puberulous; adaxial margin indistinctly nerved. Heads 17–21-flowered. Sepals free; petals 1.5–1.7 mm long.

Occurs mainly in the Kalgoorlie district from Hampton Hill Stn to near Coolgardie and Widgiemooltha; a glabrous variant occurs near Southern Cross (e.g. M.H.Simmons 1225 , PERTH). Grows on loam flats or rocky hills in Eucalyptus woodland.
