Grevillea cyranostigma is a spreading shrub that typically grows to a height of {{cvt|0.5–2|m}} and has cylindrical, woolly-hairy to silky-hairy branchlets. Its leaves are narrowly oblong, {{cvt|20–55|mm}} long and {{cvt|5–11|mm}} wide, the upper surface glabrous and glossy, the lower surface covered with silky hairs. The flowers are borne in loose clusters of a few flowers on the ends of branches and in leaf axils on a rachis {{cvt|6–12|mm}} long. The flowers are pale green and more or less glabrous, the pistil {{cvt|16–17.5|mm}} long and the style gently curved. Flowering occurs from June to October and the fruit is an oval to elliptic follicle {{cvt|14–15|mm}} long.{{cite web |title=Grevillea cyranostigma |url=https://profiles.ala.org.au/opus/foa/profile/Grevillea%20cyranostigma |publisher=Australian Biological Resources Study, Department of Agriculture, Water and the Environment: Canberra |access-date=15 March 2022}}{{cite journal |last1=McGillivray |first1=Donald |title=Australian Proteaceae: new taxa and notes |journal=Telopea |date=17 July 1975 |volume=1 |issue=1 |pages=20–21 |doi=10.7751/telopea19753102|doi-access=free }}
Taxonomy
Grevillea cyranostigma was first formally described in 1975 by Don McGillivray in the journal Telopea from specimens collected between 1890 and 1895 by [https://www.anbg.gov.au/biography/biddulph-harriette.html Harriette Biddulph] of Mount Playfair Station, who was known for her collection of plants from the Carnarvon Range.{{cite web|title=Grevillea cyranostigma|url= https://id.biodiversity.org.au/instance/apni/523586|publisher=APNI|access-date=15 March 2022}} The specific epithet (cyranostigma) is a reference to Edmond Rostand's play, Cyrano de Bergerac, as the long stigma is reminiscent of the character's protruding nose.
The species appears to be related to Grevillea sericea and G. victoriae, and is distinguished by glossier leaves than the former and a less hairy perianth than both.
Distribution and habitat
Carnarvon grevillea is restricted to the Carnarvon Range in Central Queensland, where it is found on rocky slopes on sandstone soils in dry sclerophyll forest.
Conservation status
This grevillea is listed as Least concern on the IUCN Red List of Threatened Species and under the Queensland Government Nature Conservation Act 1992. It has a wide distribution and faces no known major threats, either current or in the near future.{{cite iucn |author=Forster, P. |year=2020 |title=Grevillea cyranostigma |volume=2020 |page=e.T112651121A113309295 |doi=10.2305/IUCN.UK.2020-2.RLTS.T112651121A113309295.en |access-date=28 December 2023}}{{cite web |title=Species profile - Grevillea cyranostigma |url=https://apps.des.qld.gov.au/species-search/details/?id=9917 |publisher=Queensland Government Department of Environment and Science |access-date=15 March 2022}}
