Acacia ulicifolia (Salisb.) Court, Victorian Naturalist 73: 173 (1957)
Juniper Wattle, Prickly Moses
Erect, often straggly shrub mostly 1–2 m high. Branchlets sparsely to moderately hirsutellous to puberulous, at least at extremities. Stipules persistent, frequently >1 mm long. Phyllodes often crowded, subsessile, scattered, sometimes some subverticillate, patent, linear-triangular, flat except quadrangular when very narrow, 5–15 mm long but often <10 mm, 0.5–1.5 mm wide, pungent, rigid, green, usually glabrous; midrib prominent on each face; gland obscure, 0.5–3 mm above base. Inflorescences simple, 1 per axil; peduncles 7–15 mm long, slender, 0.3–0.5 mm diam. when dry, mostly glabrous; basal bracts 3 and fused; heads globular, 20–35-flowered, creamy yellow; bracteoles acuminate, not or scarcely exserted beyond flowers in buds. Flowers 5-merous; sepals free to 1/2-united; petals 1-nerved. Pods normally slightly constricted between seeds, 2–6 cm long, 4–6 mm wide, thinly coriaceous, dark brown to black, glabrous or subglabrous. Seeds longitudinal, oblong to elliptic, 3.5–5 mm long, normally mottled, exarillate; funicle filiform.
Occurs in the Great Divide of eastern Australia from the Grampians, Vic., through N.S.W. and A.C.T. to the Blackdown Tablelands and Ravenshoe in Qld; also NE Tas. Usually grows in sand (often over sandstone), in heath or dry sclerophyll woodland or open forest. Flowers Apr.- Oct.
Acacia ulicifolia together with A. asparagoides , A. brachycarpa , A. brownii , A. echinula , A. gunnii and A. saxicola comprise the ‘A. ulicifolia group’. Acacia quadrilateralis and A. siculiformis are not far removed from this group. The important characters of the ‘A. ulicifolia group’ include the following: phyllodes small, pungent, 4-nerved (1-nerved per face when flat) with the adaxial nerve bifurcating at the gland; basal peduncular bracts 3, commonly fused; flowers 5-merous; funicle filiform, non-arillate. Acacia brownii is sometimes treated as a variety of A. ulicifolia , e.g. L.Pedley, Austrobaileya 1: 239 (1980). However, adoption of this approach would necessitate a similar reduction in rank for A. asparagoides , A. echinula , A. saxicola and perhaps also A. brachycarpa . Such changes warrant more study than has been possible to date.
Phyllodes and flower-heads resemble A. rupicola .
Three variants, sometimes sympatric with the typical variant, occur on the north and central coast of N.S.W.: (1) a maritime variant characterised by its compact growth habit, sometimes reaching only 0.5 m in height (e.g. Tiona Beach, 8 km S of Forster, E.F.Constable 1288 , NSW), (2) a slender phyllode variant (e.g. c. 4.8 km W of Wingham, 1.6 km SW of Koolee Flat, H.Salasoo 2783 , NSW) and (3) a hairy phyllode variant (e.g. 10 km N of Dural, on the main road to Wiseman’s Ferry, M.D.Tindale s.n ., NSW167328, PERTH).
In central eastern N.S.W. there is intergradation of A. asparagoides , A. brownii , A. echinula and A. ulicifolia , particularly A. ulicifolia - A. brownii and A. ulicifolia - A. echinula and they may form hybrids, fide T.Tame, Acacias SE Australia 96 (1992). May be confused with narrow phyllode forms of A. gunnii ; these two species are sometimes sympatric and possible hybrids between them are reported by T.J.Entwistle et al ., in N.G.Walsh & T.J.Entwisle (eds), Fl. Victoria 3: 630 (1996).
