Taxonomy
Grevillea stenomera was first formally described in 1864 by botanist Ferdinand von Mueller in his Fragmenta Phytographiae Australiae from specimens collected near the Murchison River by Augustus Oldfield.{{cite web|title=Grevillea stenomera|url= https://id.biodiversity.org.au/instance/apni/470076|publisher=APNI|access-date=5 March 2023}}{{cite book |last1=von Mueller |first1=Ferdinand |title=Fragmenta Phytographiae Australiae |volume=4 |date=1864 |publisher=Victorian Government Printer |location=Melbourne |pages=85–86 |url=https://www.biodiversitylibrary.org/item/7221#page/87/mode/1up |access-date=5 March 2023}} The specific epithet (stenomera) means "narrow leaflets".{{cite book |last1=Sharr |first1=Francis Aubi |last2=George |first2=Alex |title=Western Australian Plant Names and Their Meanings |date=2019 |publisher=Four Gables Press |location=Kardinya, WA |isbn=9780958034180 |page=313 |edition=3rd}}
Distribution and habitat
Lace net grevillea is usually found in coastal scrub communities growing in sandy soils over or near limestone. The range of the plant extends from around Tamala Station, just south of Shark Bay, in the north down to around Kalbarri in the south and is found fairly close to the coast in the Geraldton Sandplains and Yalgoo bioregions of western Western Australia.
Conservation status
Grevillea stenomera is listed as "Priority Two" by the Western Australian Government Department of Biodiversity, Conservation and Attractions, meaning that it is poorly known and from only one or a few locations.{{cite web|title=Conservation codes for Western Australian Flora and Fauna|url=https://www.dpaw.wa.gov.au/images/documents/plants-animals/threatened-species/Listings/Conservation%20code%20definitions.pdf|publisher=Government of Western Australia Department of Parks and Wildlife|access-date=5 March 2023}}
Use in horticulture
The Grevillea cultivar sold by plant nurseries as "Grevillea stenomera prostrate red" is thought to be a hybrid of Grevillea pinaster.{{cite web|author=Hodge, M.|title=Mistaken identity|work=Grevillea Study Group Newsletter No.66|date=October 2003|publisher=Grevillea Study Group, Association of Societies for Growing Australian Plants|url=http://anpsa.org.au/grevSG/grev66.pdf|access-date=14 July 2012}}
