10f. Daviesia ulicifolia subsp. incarnata Chandler & Crisp (1997: 40) , Craigie (2015: 33). Type: South Australia, Southern Lofty Ranges, Cleland Conservation Park, Perimeter Track, 34°57’54’S, 138°41’37’E, G.T. Chandler 96, 13 October 1994. Holotype: CANB; isotypes: AD, K

Shrubs to 1.8 m high, glaucescent to pruinose. Root anatomy unknown. Branchlets flattened or angular. Phyllodes more prevalent towards branchlet apex, narrow-elliptic, -ovate or linear, 9.5–22 × 1–3(–5) mm, twisted at base; upper face convex with midrib more prominent than below. Unit inflorescences 1 or 2 per axil, umbellate or rarely racemose, 2–5-flowered; involucre of basal bracts present, prominent, imbricate, keeled, 1–2 mm long; peduncle 0.2–3.5 mm long; rachis 0–0.2 mm long. Pedicels 1–3.5 mm long. Calyx ca. 3.5 mm long including the 0.5–1 mm receptacle, faintly to prominently ribbed, campanulate, upper lobes united slightly higher, all lobes acute, minutely ciliate at margins. Corolla : standard broadly obovate to broadly elliptic, emarginate, 7–8 × 7.5–9.5 mm including the ca. 1–2 mm claw, deep red-orange with a dark red band circling the yellow centre; wings deeply auriculate, ca. 6–7 × 2–3 mm including the ca. 2 mm claw, maroon centrally grading to orange-red at the margins and apex; keel acute, slightly auriculate, ca. 5–6 × 2–3 mm including the ca. 2 mm claw, deep red. ( Fig. 11F ).

Flowering period:— late September to early November. Fruiting period: October to November.

Distribution:— Endemic to South Australia, where it extends throughout the Mt Lofty Range, with isolated records from Yorke Peninsula, the southern Flinders Ranges and Kangaroo Island.

Habitat:— Sandy to rich loamy soils, in undulating hilly to mountainous country. The vegetation is varied, usually Eucalyptus -dominated sclerophyll communities, often with other legume species.

Selected specimens (15 examined):— SOUTH AUSTRALIA. Lofty South: Blewitt Springs, 35°10’S, 138°36’E, R . Filson 3094, 4 September 1960 ( CANB, MEL); 2.5 km E of Clarendon town centre towards Kangarilla at the intersection of Grants Gully Road and Bakers Gully Road, 35°07’33’ S , 138°38’29’E, G.T. Chandler 112, 16 October 1994 ( CANB). Flinders Ranges: Mt Charles , ca. 30 km NE of Port Pirie, ca. 33°07’S, 138°09’E, M . Sharrad 1460, 23 September 1967 ( AD) .

Affinity:— This subspecies resembles the subumbellate-inflorescence form of D. ulicifolia subsp. ulicifolia and both subspecies also share relatively large standards and phyllodes. However, D. ulicifolia subsp. incarnata has a rosy red to deep orange-red standard, whereas subsp. ulicifolia has a mostly yellow standard. Some inflorescences of subsp. incarnata are slightly racemose, resembling those of subsp. aridicola , which also has a similar flower colour, though the standard is much larger in subsp. incarnata .
