Description
editGrevillea oncogyne is an erect to spreading shrub that typically grows to a height of 0.6–3 m (2 ft 0 in – 9 ft 10 in) and sometimes forms a lignotuber. Its leaves are linear, mostly 50–120 mm (2.0–4.7 in) long and 1–2 mm (0.039–0.079 in) wide, sometimes with two to four linear lobes 50–90 mm (2.0–3.5 in) long. The edges of the leaves are rolled under, obscuring the lower surface. The flowers are arranged in leaf axils or on old wood on a silky-hairy rachis 5–30 mm (0.20–1.18 in) long. The flowers are red or pinkish red, the pistil 36–40 mm (1.4–1.6 in) long. Flowering mainly occurs from October to December and the fruit a follicle 7–15 mm (0.28–0.59 in) long with prominent ridges on one side.[2][3]
Taxonomy
editGrevillea oncogyne was first formally described in 1904 by Ludwig Diels in Ernst Georg Pritzel's Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie.[4][5] The specific epithet (oncogyne) means "swollen woman", referring to swellings on the ovary.[6]
Distribution and habitat
editThis grevillea grows on rocky outcrops in mallee woodlands and shrublands between Boorabbin, Coolgardie, Salmon Gums, Lake King and Hyden in the Avon Wheatbelt, Coolgardie, Esperance Plains and Mallee bioregions of inland south-western Western Australia.[2][3]
Conservation status
editGrevillea inconspicua is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.[3]
