Description
40b. Daviesia nudiflora Meisner (1844: 53) subsp. amplectens Crisp (1995: 1214). Type: Western Australia, Avon, 8 km NE of Dowerin, 31°09’S, 117°05’E, M. D. Crisp 6536, 18 July 1980. Holotype: CBG; isotypes: AD, CANB, K, L, NSW, PERTH
Bushy shrubs to 2.5 m high × 3 m wide. Branchlets sharply angular with decurrent midribs. Phyllodes produced all along the branchlets, crowded (in typical specimens, margins of adjacent phyllodes are in contact) or closely spaced (up to 5 mm apart), spreading at 60–90°, broadly ovate, concave above, acuminate with a long, rigid, pungent apex, basally amplexicaul and cordate or truncate, 5–18 × 4–15 mm, smooth, glaucous to pruinose. Unit inflorescences distributed along branchlets, in axils of phyllodes. Corolla: standard broadly ovate, 9–10 × 7–9 mm including the claw. Pod sharply curved along lower suture, 10–13 × 7–9 mm. (Figs 38D–F, 39A).
Distribution:— Western Australia, in the north-eastern wheatbelt from Mt Collier, NE of Cadoux, south to the area around Dowerin.
Selected specimens (12 examined):— WESTERN AUSTRALIA. Avon: Dowerin, 31°12’S, 117°02’E, B. Rosier 50, August 1959 (PERTH); 1 km SW of Amery railway station, 31°10’S, 117°04’E, M. D. Crisp 6342, 3 October 1979 (AD, CBG, MEL, NSW, PERTH, UWA); Amery town site, western boundary, 31°08’S, 117°05’E, B. H. Smith 388, 3 August 1984 (AD, CBG, HO, MEL, NSW, PERTH); Namalcatching Well reserve, 15 km E of Dowerin, B. V. Smith 1, 25 April 1981 (CBG); N of Cadoux, 7 km E of Kirwan, M. D. Crisp 6690, 23 July 1980 (AD, CBG, K, MEL, NSW).
Affinity:— This is the most distinctive of the subspecies of D. nudiflora (Crisp 1995) and, if only the typical populations (from around Dowerin) were known, it would be treated as a species. However, some populations north of Cadoux clearly show a link to subsp. drummondii, as seen in the wider spacing of the nodes, the slightly narrower shape of the phyllodes, and a glaucous rather than pruinose epidermis, e.g. Lally & Lepschi TR 1113 (CANB, PERTH) from Petrudor Rocks area and B.V. Smith 5 (CBG 8102467) from near Mt Collier.
