7. Daviesia wyattiana Bailey (1880: 102) View in CoL , Stanley & Ross (1983: 253), Crisp (1995: 1245), Crisp (2002: 527), Jeanes (1996: 756). Type: ‘... which I found about eighteen months ago growing among rocks at the Eight-mile Plain, a locality to the south of Brisbane.’ Lectotype (Crisp 1995: 1245): Eight-mile Plain amongst rocks, F.M. Bailey s.n., October 1878 (MEL 72493); isolectotype: BM, BRI
Sparse shrubs, 1–2.5 m tall, glabrous. Root anatomy unknown. Branchlets triquetrous, angular, 1.5–3 mm broad. Phyllodes scattered, spreading to ascending, linear, apically acute or obtuse, tapered to articulate base, decurrent, 40–370 × 2–8(–10) mm, grey-green, glabrous; midrib prominent; venation pinnate, obscure. Unit inflorescence 1(– 3) per axil, umbelliform, 4–7-flowered; peduncle 7–37 mm long; barren basal bracts triangular becoming oblong further up peduncle, keeled, to 1 mm long; subtending bracts oblong, keeled, spreading at tips, 1.5–2 mm long. Pedicels filiform, 6–17 mm long. Calyx 3.7–5 mm long including 0.75–1.5 mm receptacle, green except for dark red margins in the sinuses; lobes subequal, acute, ca. 1.5 mm long; upper 2 lobes united slightly higher than the lower 3, apices scarcely recurved. Corolla : standard depressed-ovate, emarginate, 6.5–8.5 × 6.5–9 mm including the 1–1.5 mm claw, with 2 small calli at the base of the lamina, yellow with red or purplish veins radiating from a ring surrounding the pale yellow centre; wings obovate with a rounded apex, strongly auriculate, 5–6.5 × 1.5–2.5 mm including the ca. 1.5 mm claw, basally red grading to orange or yellow at apex; keel half transversely elliptic, acute, auriculate, saccate, 4.5–5 × 1.5–2 mm including the 1–1.5 mm claw, light red. Stamens strongly dimorphic: inner whorl of 5 with slender, terete filaments and shorter, round, versatile anthers with confluent thecae; outer whorl of 5 with broader, compressed filaments and longer, oblong, basifixed, 2-celled anthers; filaments free. Pod obliquely shallowly obtriangular, acuminate to acute, ± compressed, 7–11 × 4–6 mm; upper suture slightly sigmoid to slightly recurved; lower suture acute. Seed ellipsoid, 4.1–5.2 mm long, 2–2.5 mm broad, 1.4–1.7 mm thick, light brown with black mottling; aril 2.3–3 mm long. ( Fig. 8 View FIGURE 8 ).
Common name:— Long-leaf Bitter-pea.
Flowering period:— Rarely in April, mostly August to November. Fruiting period: Rarely in May, mostly September to December.
Distribution:— From the central sandstone ranges of Queensland, extending southward to the north coast of New South Wales almost as far as Coffs Harbour, then disjunct to the ranges of the NSW south coast and extending south to East Gippsland, Victoria.
Habitat:— Usually on ridges, on skeletal soils derived from sandstone, granite and acidic volcanic rocks, in the shrubby understorey of dry sclerophyll forest.
Conservation status:— Not threatened. The species is officially declared Vulnerable in Victoria because a small population occurs in the far east of the state; however, this is at the very southern end of its natural distribution and it occurs extensively in New South Wales and Queensland.

Affinity:— Daviesia wyattiana most closely resembles D. stricta , which is endemic in the Flinders Ranges, South Australia. Though the umbellate inflorescences and triquetrous, winged branchlets are obvious similarities between these two species, D. stricta may be easily distinguished by the calyx, which enlarges significantly in fruit, is viscid, and has acuminate, maroon, strongly recurved calyx–lobes. Also, D. stricta has shorter peduncles (3–7 mm) and pedicels (2–5 mm), and longer pods (9–13 mm long).
