Taxonomy
This pomaderris was first formally described in 1863 by George Bentham who gave it the name Pomaderris ferruginea var. canescens in Flora Australiensis from specimens collected on Percy Island by Allan Cunningham.{{cite web |title=Pomaderris ferruginea var. canescens |url=https://biodiversity.org.au/nsl/services/rest/instance/apni/517264 |publisher=Australian Plant Name Index |accessdate=21 January 2022}}{{cite book |last1=Bentham |first1=George |last2=von Mueller |first2=Ferdinand |title=Flora Australiensis |volume=1 |date=1863 |publisher=Lovell Reeve & Co. |location=London |page=417 |url=https://www.biodiversitylibrary.org/item/3669#page/475/mode/1up |access-date=21 January 2022}} In 1951, Norman Arthur Wakefield raised the variety to species status as Pomaderris canescens in The Victorian Naturalist.{{cite web |title=Pomaderris canescens |url=https://biodiversity.org.au/nsl/services/rest/instance/apni/516590 |publisher=Australian Plant Name Index |accessdate=21 January 2022}} The specific epithet (clivicola) means "slopes-dweller".
