Acacia flavipila A.S.George (as ‘flavopila’), W. Austral. Naturalist 10(2): 32 (1966)

Spreading shrub 0.5–2 m high. Branchlets crispate-villous to puberulous or appressed-puberulous, the hairs golden or white on young shoots. Stipules persistent, c. 1 mm long. Phyllodes elliptic to widely elliptic, oblong-elliptic or oblanceolate, mostly inequilateral, 10–22 mm long, 3–9 mm wide, rounded to obtuse, sometimes emarginate, mucronulate, minutely crispate-villous or glabrous, with 2 or 3 main nerves and frequently anastomosing secondary nerves; gland 1–5 mm above pulvinus. Inflorescences (1- or) 2-headed racemes; raceme axes 1–7 mm long, sericeous to minutely pilose with golden hairs; peduncles 3–6 mm long, sericeous to minutely pilose, with pale yellow to bright golden hairs; heads globular, 4–5.5 mm diam., 28–35-flowered, golden; bracteoles ovate, lanceolate or quadrate-ovate, exserted or not in buds. Flowers 5-merous; sepals free, golden-puberulous. Pods linear, coiled or only arcuate, to 3 cm long, 3–4 mm wide, villous. Seeds not seen.

Scattered from near Cadoux SE to near Dunn Swamp (c. 89 km NE of Ravensthorpe), in south-western W.A.

Acacia flavipila together with A. auratiflora , A. cassicula , A. consobrina , A. ixiophylla , A. kingiana , A. lanei , A. lanuginophylla , A. lobulata , A. loxophylla , A. spongolitica , A. trulliformis , A. verricula and A. vittata constitutes the ‘A. flavipila group’. Closely related to A. consobrina and superficially similar to A. chrysopoda .

Acacia loxophylla var. nervosa (see Doubtful Names ) appears referable to the ‘A. flavipila group’ but cannot be accommodated within any of the above mentioned taxa.

Occurs as two varieties in southern W. A.

Phyllodes elliptic to oblong-elliptic or oblanceolate, mostly obviously tomentulose, 2 to 3 times longer than wide, not strongly resinous; bracteoles exserted in buds

var. flavipila

Phyllodes widely elliptic to elliptic, glabrous or sparsely hairy, mostly less than twice as long as wide, the base and often nerves strongly resinous-viscid; bracteoles not exserted in buds

var. ovalis

 

Acacia flavipila A.S.George var. flavipila

Shrub not obviously resinous. Phyllodes elliptic to oblong-elliptic or oblanceolate, mostly 1.5–2.2 cm long, 3–6 mm wide, 2–3 times as long as wide, mostly obviously tomentulose. Bracteoles ovate to lanceolate, long-pedicellate, exserted in buds.

Infrequent from Westonia S to near Dunn Swamp but locally common in Kulin area, south-western W.A. In low eucalypt woodland in poorly to well drained clay loam or brown sand.

Type of accepted name
