67. Daviesia argillacea Crisp (1995: 1171) View in CoL . Type: Western Australia, Roe, ca. 55 km SSW of Norseman, 5 km from highway towards Peak Charles GoogleMaps , 32°38’S, 121°29’E, M. D. Crisp 5956, J. Taylor & R. Jackson, 20 September 1979. Holotype: CBG; isotypes: K, NSW, PERTH
Daviesia obtusifolia Mueller (1860: 104) var. parvifolia E.Pritz. View in CoL in Diels & E.Pritzel (1904: 247). Type: ‘Hab. in distr. Coolgardie pr. Gilmores in fruticetis lutosis fruct. m. Nov. (D. 5270)’ (B†). The type is missing, presumably destroyed in the Berlin herbarium during the Second World War ( Hiepko 1987). However, from the description it seems probable that this taxon is conspecific with D. argillacea View in CoL .
Daviesia phyllodinea Moore (1920: 168) var. parvifolia S. Moore (1920: 168) View in CoL . Type: ‘Bruce Rock; Stoward, 469.’ Holotype: BM.
Erect, bushy shrubs, to 2 m or higher, glabrous, glaucescent. Root anatomy with anomalous secondary thickening (cord type) or normal (unistelar). Branchlets ascending, terete, lightly ribbed. Phyllodes fairly crowded, erect, usually narrowly obovate, rarely narrowly elliptic, usually obtuse and mucronate at apex, tapered to base, articulate, 7–22(–35) × 3–6 mm; midrib visible, venation obscure. Unit inflorescences 1(2) per axil, flowers solitary or 2–3 in racemes; peduncle 0.25–2 mm long; rachis 0–1.5 mm long; subtending bracts ascending, spathulate, hooded, ca. 0.75 mm long. Pedicels 1–2.5 mm long. Calyx View in CoL campanulate or tapering, 3.5–4 mm long including the ca. 1–1.25 mm receptacle, dull green with purple margins; upper 2 lobes united in a truncate, emarginate lip, ca. 0.5 mm long; lower 3 lobes triangular, ca. 0.5 mm long. Corolla View in CoL : standard transversely elliptic, emarginate, cordate, 4.5–5 × 5–6.5 mm including the ca. 1.5 mm claw, orange to orange-yellow with a dull red or maroon centre; wings obliquely elliptic, rounded and incurved at apex, scarcely overlapping, auriculate, ca. 4.5 × 2 mm including the 1.5 mm claw, orange with maroon infusion towards base; keel half transversely elliptic, scarcely acute, auriculate, saccate, ca. 4 × 2 mm including the 1.75 mm claw, maroon. Stamens strongly dimorphic: inner whorl of 5 with longer, terete filaments and shorter, round, versatile anthers with confluent thecae; outer whorl of 5 with shorter, compressed filaments and longer, oblong, basifixed, 2-celled anthers; filaments free. Pod obliquely shallowly obtriangular, ± acute, compressed, 5–7 × 3.5–4.5 mm, thin-walled; upper suture strongly sigmoid; lower suture acute. Seed not seen. ( Fig. 67 View FIGURE 67 ).
Flowering period:— July to October. Fruiting period: November.
Distribution:— Southern Western Australia, widespread in the region approximately delimited by Southern Cross, Narembeen, the Pallinup River, Mt Ragged and Lake Lefroy.
Habitat:— Grows in sand, sandy, clayey or gravelly soils over laterite or granite, mostly on flat landscapes in eucalypt woodland or mallee shrubland with understorey shrubs such as broombush ( Melaleuca spp. ) or Dodonaea Miller (1754 : [unpaged]).

Affinity:— This species is readily recognised in Western Australia by its phyllodes alone: no other Daviesia there has phyllodes that are flat, narrowly obovate or elliptic, non-pungent, small (mostly 7–25 mm long), somewhat glaucous, with a single nerve (midrib) and unthickened margins. The phyllodes of D. lancifolia may appear similar but are more or less pungent and the plant is procumbent or prostrate. Phyllodes of D. grahamii and D. newbeyi may also appear similar, but have thickened margins, and additionally the calyces are 5-ribbed. The habit of D. argillacea is erect, and its calyx is not ribbed. Daviesia emarginata may also appear similar; in fact, D. argillacea was formerly

included under this species, as D. obtusifolia var. parvifolia . However, D. emarginata usually has larger, emarginate phyllodes and very different flowers, notably with a white-dotted calyx and an elongated, stipe-like receptacle that is as long as the body of the calyx. In floral and fruit characters, as well as the flat, non-pungent phyllodes, D. argillacea resembles D. mimosoides and related species in eastern Australia. However, these have either larger phyllodes ( D. mimosoides and D. suaveolens ), or more than two flowers per raceme ( D. buxifolia and D. elliptica ), or both.
