Common name: Stony Bush-pea
Pultenaea setulosa Benth. APNI*
Description: Erect to decumbent shrub; stems glabrous to spreading to appressed-pubescent.
Leaves alternate, linear to narrow-obovate to elliptic, concave, 3.5–15 mm long, 0.5–1.5 mm wide, apex acuminate and recurved to straight, margins involute, surfaces smooth to tuberculate, concolorous; stipules mostly 2–4 mm long.
Inflorescences subterminal or apparently terminal, dense, leafy at the base, the leaves often smaller and with enlarged stipules; bracts each composed of a leafless pair of stipules. Flowers 5–13 mm long; pedicels 0.5–3 mm long; bracteoles 1–8 mm long, narrow-ovate, acuminate to bristly, glabrous, attached on or at base of calyx tube, stipules c. 2/3 length of bracteoles. Calyx 3.5–8 mm long, glabrous to sparsely hairy; teeth acuminate. Ovary glabrous or with a few hairs at base of style.
Pods 5–6 mm long, turgid.
Distribution and occurrence: Grows in dry sclerophyll forest; west to Gilgandra district.
NSW subdivisions: CC, NT, CT, NWS, CWS, SWS
Other Australian states: Qld Vic.
As treated here, this species is a variable complex of populations distributed from Qld to Vic. In the past, several of these have been recognized as distinct species (see synonymy). One of us (RdK) considers these to be an intergrading series of geographic variants comprising one widespread species. However, the P. setulosa complex is still the subject of ongoing taxonomic research.
