It is an erect and open to low, dense shrub with oblong, broadly elliptic or linear leaves, and red and yellow, or red, white and apricot-coloured, sometimes all yellow flowers.

Description

Grevillea celata is an erect, open or low, dense shrub that typically grows to a height of {{cvt|0.4–1.8|m}} and forms suckers. Its leaves are oblong, broadly elliptic or linear, mostly {{cvt|20–44|mm}} long and {{cvt|4–18|mm}} wide with the edges turned down or rolled under. The lower surface of the leaves is woolly-hairy. The flowers are usually arranged in groups of two to eight on the ends of branchlets or short side shoots on a rachis {{cvt|1–5|mm}} long, and are red and yellow, or red, white and apricot-coloured, sometimes all yellow, the pistil {{cvt|18–25|mm}} long, the style red with a green base and tip. Flowering occurs from July to February, and the fruit is a woolly-hairy follicle {{cvt|14–16|mm}} long.{{cite journal |last1=Molyneux |first1=William M. |title=Grevillea celata (Proteaceae), a new species from central eastern Gippsland, Victoria |journal=Muelleria |date=1995 |volume=8 |issue=3 |pages=311–316 |url=https://www.biodiversitylibrary.org/item/209924#page/53/mode/1up |access-date=21 February 2022}}{{cite web |last1=Makinson |first1=Robert O. |title=Grevillea celata |url=https://profiles.ala.org.au/opus/foa/profile/Grevillea%20celata |publisher=Australian Biological Resources Study, Department of Agriculture, Water and the Environment |access-date=21 February 2022}}

Grevillea alpina and G. chrysophaea are similar species, but neither forms suckers.

Taxonomy

Grevillea celata was first formally described in 1995 by Bill Molyneux in the journal Muelleria from specimens he collected from Colquhoun State Forest in south-eastern Victoria in 1993.{{cite web|title=Grevillea celata|url= https://id.biodiversity.org.au/instance/apni/559475|publisher=APNI|access-date=21 February 2022}} The specific epithet (celata) means "hidden" or "concealed within", referring to the earlier confusion with G. alpina and G. chrysophaea.

Distribution and habitat

Nowa Nowa grevillea grows in dry sclerophyll woodland in Colquhoun State Forest near Bruthen in south-eastern Victoria.

Conservation status

The species is listed as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act, as "critically endangered" in Victoria under the Flora and Fauna Guarantee Act 1988{{cite web |title=Grevillea celata |url=https://vicflora.rbg.vic.gov.au/flora/taxon/c5f363f4-cb85-43d6-9e20-98b6fb7c946b|publisher=Royal Botanic Gardens Victoria |access-date=30 December 2023}} and as "vulnerable in Victoria" on the Department of Sustainability and Environment's Advisory List of Rare Or Threatened Plants In Victoria, and a National Recovery Plan has been prepared. The main threats to the species include inapprpriate fire regimes, road works, and browsing by kangaroos.{{cite web |last1=Carter |first1=Oberon |last2=Walsh |first2=Neville |title=National Recovery Plan for the Colquhoun Grevillea Grevillea celata |url=https://www.awe.gov.au/sites/default/files/documents/g-celata.pdf |publisher=Victorian Government Department of Sustainability and Environment |access-date=21 February 2022}}{{cite web |title=Advisory list of rare or threatened plants in Victoria - 2014 |url=https://www.environment.vic.gov.au/__data/assets/pdf_file/0021/50448/Advisory-List-of-Rare-or-Threatened-Plants-in-Victoria-2014.pdf |publisher=Victorian Government Department of Environment and Primary Industries |access-date=21 February 2022}}
