10b. Daviesia ulicifolia subsp. stenophylla Chandler & Crisp (1997: 42) , Crisp (2002: 528). Type: New South Wales, North Coast, 52 km from Clarence River crossing at Grafton towards Casino along the Cummerland Highway, 29°17’30’S, 152°59’40’E, G.T. Chandler 75, 6 September 1994. Holotype: CANB; isotypes: BRI, NSW

Daviesia ulicina Sm. f. angustifolia Bentham (1864: 81) . Type: ‘Queensland and N. S. Wales.’ Type: In a range of specimens seen by Bentham (K, MEL), it is unclear which typifies this name. This is not the same taxon as D. umbellulata auct . non Sm. var. angustifolia DC. , which is based on D. umbellata Labill. We know this because Bentham (1864: 81) placed D. umbellata Labill. as a synonym of his taxon D. ulicina f. subumbellata (= D. ulicifolia subsp. ulicifolia in the present treatment—see above).

Daviesia ulicina Sm. var. angustifolia Bailey (1883: 90) . Type: ‘The common form about Brisbane. ’ Type: Unknown.

Shrubs rather delicate and not rigid. Phyllodes slender, linear-elliptic to slightly linear-ovate, 8–20 × 0.5–1.5 mm; upper face convex with midrib more prominent than below. Unit inflorescences 1 or 2 per axil, 1-flowered; peduncle nil. Pedicels 0.7–2.5 mm long. Calyx 3–3.5 mm long including the ca. 0.5 mm receptacle. Corolla : standard 6–7 × 5–6.5 mm including the ca. 2 mm claw, bright yellow infused with red which darkens toward the yellow centre; wings deeply auriculate, 4–5.5 × 2 mm including the ca. 1.5 mm claw, dark red centrally grading to orange or yellow at the margins and apex; keel very acute, auriculate, 4 × 2 mm including the ca. 1 mm claw, maroon or dark red. ( Fig. 11A ).

Flowering period:— August and September. Fruiting period: September and October, also November in the southerly limits.

Distribution:— Disjunct in far north Queensland (western side of the wet tropics ranges) and then more or less continuous from central Queensland to the Central Coast of New South Wales (rarely on the South Coast of NSW). Predominantly coastal, this subspecies occasionally occurs inland, e.g. the Pilliga Scrub of New South Wales and central Queensland ranges.

Habitat:— Mostly growing in coastal sandy or clay loams, though further inland the soils tend to be rockier. Vegetation is varied, though this subspecies grows vigorously in disturbed sites such as road and power line clearings.

Selected specimens (25 examined):— QUEENSLAND. Maranoa: 6 km E of Yuleba, Warrego Hwy , 26°37’S, 149°26’E, M . D. Crisp 11741, 3 September 2016 ( BRI, CANB). Wide Bay: 2.5 km from Bruce Highway towards Caloundra, turnoff on S side of road, 26°46’45’S, 153°03’45’E, G.T. Chandler 81, 7 September 1994, ( CANB, BRI). Cook: Mt Windsor Tableland , 16°26’S, 145°11’E, B. L . Hyland 4888, 19 June 1969 ( QRS) . NEW SOUTH WALES. North Coast: 4 km S Buladelah along Pacific Highway, near rest area on side of road, 32°26’30’ S , 152°11’30’E, G.T. Chandler 62, 5 September 1994, ( CANB, NSW). Central-west slopes: Goonoo State Forest , ca. 8 km E of Moriguy, 32°04’S, 148°43’E, E. F . Constable 21, 9 December 1961 ( NSW, NT, PERTH) .

Affinity:— This subspecies most closely resembles D. ulicifolia subsp. ulicifolia (east coastal form) but the phyllodes are narrower and often longer and the flowers slightly smaller. The whole aspect of the plant is rather slender, and the shrubs are distinctly soft compared with the fierce rigidity of the other subspecies. By contrast, subsp. ruscifolia has ovate phyllodes that are wide at the base, subsp. incarnata has longer and wider phyllodes and subsp. aridicola has very thick, rigid, glaucous phyllodes. Also, subsp. incarnata and subsp. aridicola have umbellate or racemose inflorescences, whereas subsp. stenophylla has flowers solitary or in pairs in the axils. Subsp. stenophylla has small flowers, as does subsp. ulicifolia and subsp. aridicola , but subsp. ruscifolia and subsp. incarnata have very large flowers, which also have a red or orange standard, in contrast to yellow in the other subspecies.
