Phytotaxa 300 (1) © 2017 Magnolia Press • 143 free. Pod obliquely shallowly obtriangular, acute, compressed, 6.5–8 × 5–6 mm; upper suture sigmoid; lower suture acute. Seed not seen. ( Fig. 61 View FIGURE 61 ).

Chromosome number:— n = 9, 2n = 18 (voucher Sands 628.2.12, cited under D. squarrosa var. squarrosa by Sands 1975).

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

Distribution:— Known only from New South Wales, where it occurs mainly along the eastern escarpment of the Northern Tablelands from near Tenterfield in the north to the headwaters of the Hastings River in the south; also recorded near Warialda on the North-west Slopes. This species possibly occurs in Queensland because one population (Crisp 7310) is only 1 km from the state border.

Habitat:— Grows in sandy soils, usually derived from granite, at elevations of 500–1000 m. Associated vegetation is open forest dominated by eucalypts, with a sclerophyll shrub understorey; less commonly occurring in woodland or heath.

Affinity:— Specimens of Daviesia nova-anglica were once referred to D. squarrosa var. squarrosa (= D. squarrosa ). Daviesia squarrosa may be distinguished most readily by its smaller upper bracts (0.5–0.8 mm long and 0.3–0.4 mm broad). Phyllode shape also differs in these species, although the distinction is more subtle. In D. squarrosa , the phyllodes are basically heart-shaped with a pronounced cuspidate apex 3–5 mm long, whereas in D. nova-anglica , they are basically ovate with a shorter, acuminate apex up to 4 mm long. Daviesia villifera and D. pubigera differ from both these species in being hispid all over the phyllodes, and D. villifera is further differentiated by the hooked, beaked keel-petal.
