Common name: Marlborough 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.
NSW subdivisions:
Other Australian states: Qld
Threatened species: Commonwealth EPBC: Vulnerable
As previously 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. One of us (RdK) considers these to be an intergrading series of geographic variants comprising one widespread species. However, the P. setulosa complex is the subject of ongoing taxonomic research. [Note: Research in 2022 shows that this species should be restricted to Queensland. Specimens from NSW belong to multiple taxa with a revision of species concepts in preparation by R.L.Barrett, J.Clugston and colleagues.]
