5. Daviesia acicularis Smith (1805: 506) View in CoL , Bentham (1864: 81), Stanley & Ross (1983: 254), Crisp (1995: 1169), Crisp (2002: 527). Type: ‘Port Jackson, N.S. Wales, Mr. White, 1793’ Holotype: LINN; isotypes: BM, G (3 sheets), LIV

D. pungens A.Cunn. ex Bentham (1837b: 11) View in CoL , nom. inval., given as a synonym of D. acicularis Sm. View in CoL Type: Not designated.

Erect shrubs, 0.2–1 m high, glabrous to densely hispid on branchlets. Root anatomy normal (unistelar). Branchlets ascending, not spinescent, terete, ribbed. Phyllodes scattered, spreading and gently recurved, horizontally compressed or flattened but often appearing terete because of the revolute margins, linear, apex acuminate and pungent, margins with scattered teeth, base cuneate, articulate, 9–42 × 0.75–4 mm. Juvenile phyllodes obovate to elliptic, flat, hardly spinescent, (20–)25–65 × 3–10 mm for 3–4 nodes (though occasionally numerous) before grading into adult phyllodes. Unit inflorescences 1(2) per axil, 1-flowered; peduncle nil; subtending bracts ascending to appressed, oblong, ca. 1 mm long. Pedicel 1.5–2.5 mm long. Calyx View in CoL 4–5 mm long including the 0.5– 0.75 mm receptacle; lobes equal, triangular, 1.5–3 mm long. Corolla View in CoL : standard broadly elliptic, emarginate, 6.5–7 × 5–6 mm including the ca. 1 mm claw, adaxially (yellow-) orange with with dark red veins radiating from a ring surrounding the pale yellow centre, abaxially mostly dark red especially the veins, with a central yellow stripe; wings obovate, apex rounded, deeply auriculate, 5.5–6.5 × 1.5–2 mm including the 1.5–2 mm claw, orange with a central maroon stripe tapering towards apex; keel half transversely ovate, acute, slightly auriculate, slightly saccate,

5.5–6 × 1.5–1.75 mm including the ca. 2.5 mm claw, apically dark red, becoming paler and pink towards base. Stamens strongly dimorphic: inner whorl of 5 with longer, slender terete filaments and shorter, round, versatile anthers with confluent thecae; outer whorl of 5 with shorter, compressed filaments and longer, oblong, 2-celled, basifixed anthers; filaments free. Pod obliquely shallowly obtriangular with an acuminate apex and long, persistent style, 7–8 × 4.5–6 mm; upper suture sigmoid; lower suture acute. Seed globose, 3.5–4.3 mm long, 2.1–2.7 mm broad, 1.4–2 mm thick, light to dark brown with black mottling; aril 1.5–2 mm long. ( Fig. 6 View FIGURE 6 ).

Flowering period:— August to November. Fruiting period: October to December.

Distribution:— Widespread in eastern Australia, from Tambo, central Queensland, south-west to the Charleville and Gilruth Plains area, and also along the coast and Great Dividing Range from Fraser Island (Queensland) south through New South Wales to the Victorian border.

Habitat:— Grows on a variety of substrates, from sand to clayey sand or occasionally loam on plains, undulating terrain or mountain ridges, in open forest dominated by Eucalyptus , or mixed forest of Eucalyptus and Callitris Ventenat (1808: 10) , or Triodia hummock grassland with Eucalyptus and Acacia .

Affinity:— Daviesia acicularis is superficially similar to D. ulicifolia , though the toothed and usually recurved phyllode margins distinguish D. acicularis quite readily from D. ulicifolia . Occasionally, it has been confused with D. genistifolia , but the terete or vertically compressed phyllodes easily distinguish this species from D. acicularis .
