'''''Sphalmium''''' is a monotypic genus of flowering plants in the protea family.<ref name=OriginalPublWhite1939/><ref name=SphalmiumPublBriggsetal1975/><ref name=FloraAustralia/><ref name="RFK8"/> The only species, '''''Sphalmium racemosum''''', is a large forest tree. Common names include '''satin silky oak''', '''mystery oak''', '''Mt Lewis oak''', '''poorman's fishtail oak''' and '''buff silky oak'''.<ref name=FloraAustralia/><ref name="RFK8"/>

==History== Botanists Barbara Briggs, Bernie Hyland and Lawrie Johnson named the new genus, updated the description and named the new species combination in 1975.<ref name=SphalmiumPublBriggsetal1975/><ref name=APNI/> They based the new species combination name on Cyril T. White's 1939 description of ''Orites racemosa'', now a synonym.<ref name=OriginalPublWhite1939/>
