31. Daviesia lancifolia Turczaninow (1853: 263) View in CoL , Crisp (1995: 1206). Daviesia mollis Turcz. var. minor Bentham (1864: 74) —replacement name for D. lancifolia Turcz. Type: ‘Drum. IV. n. 28. Holotype: KW; isotypes: BM (2 sheets), FI-W, G (2 sheets), K (2 sheets), MEL, W

Daviesia pedunculata Benth. View in CoL in Lindley (1839: xiv) [var.] b minor Meisner (1844: 53). Type: ‘In glareosis sterilibus ad radices collium Konkoberuphills (Kent) d. 21. Nov. 1840. Herb. Preiss. no. 1154.’ Lectotype (Crisp 1995: 1206): LD; isolectotype: G (2 sheets), NY.

Prostrate to spreading-erect shrubs, to 0.5 m high and to 1 m broad, scabrous to occasionally glabrous and ± glaucous on vegetative parts. Root anatomy normal (unistelar). Branchlets terete, lightly ribbed. Phyllodes scattered, erect, mostly elliptic to obovate (to narrowly or broadly so), occasionally cuneate, ovate, orbicular or linear, apically truncate to acuminate, with the tip varying from pungent to mucronate (less rigid), marginally ± irregularly crenulate in the upper half, basally cuneate and constricted to a short pseudo-petiole, articulate at branchlet, 7–17(–20) × 2–11 mm. Unit inflorescences 1 or 2 per axil, umbellate or condensed racemes, 3–5- flowered; peduncle 9–31 mm long; rachis from almost nil to 4 mm long; subtending bracts oblong to narrowly triangular, keeled, spreading at the tips, 0.5–2 mm long; barren bracts oblong, keeled, ca. 1 mm long. Pedicels 3–7 mm long, somewhat viscid, thickened towards the apex, which is flanged. Calyx View in CoL 3–4 mm long including the ca. 1 mm receptacle, all lobes having recurved tips; upper 2 lobes united in a truncate, emarginate lip, 2–2.5 mm long; lower 3 lobes narrowly triangular, ca. 2 mm long. Corolla View in CoL : standard broadly ovate, emarginate, 6–7 × 6–6.5 mm including the 1–1.5 mm claw, with 2 small calli at the base of the lamina, yellow to pale orange with a thin (often faint) red ring surrounding the yellow centre; wings obovate with a rounded apex, auriculate, 6–7 × 2–2.5 mm including the 1–1.5 mm claw, yellow to red; keel half transversely ovate, acute, supervolute, auriculate, saccate, 5.5–7.5 × 1.5–2 mm including the ca. 1.5 mm claw, yellow to red. Stamens strongly dimorphic: inner whorl of 5 with longer, slender terete filaments and shorter, round, confluent, subbasifixed anthers; outer whorl of 5 with shorter, broader, compressed filaments and longer, oblong, 2-celled, basifixed anthers; filaments free. Pod obliquely shallowly-obtriangular with an acute or attenuate apex, 8–9 × 5–6 mm; upper suture strongly sigmoid; lower suture obtuse. Seed not seen. ( Fig. 32 View FIGURE 32 ).

Flowering period:— October to March. Fruiting period: One specimen fruiting in January seen.

Distribution:— Western Australia, southern wheatbelt and south coast, from Narrogin and the Stirling Range east to the Hyden area and Mt Ragged.

Habitat:— Grows on sand, gravel, sandy clay, lateritic clay or rocky soils, in heath or mallee-shrublands.

Affinity:— Daviesia lancifolia is similar in appearance to D. mollis and D. pedunculata . Daviesia mollis can be readily distinguished by its phyllodes, which are broadly obovate or orbicular, 5–15 mm broad, pungent, green and conspicuously and softly hirsute. Daviesia pedunculata has ovate to elliptic phyllodes, the flowers are larger (e.g. calyx 5–6 mm long, standard 7.5–10 mm long), the standard has a large and conspicuous central maroon patch with a vertical yellow stripe, and the pods are larger (15–18 mm long).
