Sphalmium is a monotypicgenus of flowering plants in the proteafamily.[1][2][3][5] 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.[3][5]
Botanists Barbara Briggs, Bernie Hyland and Lawrie Johnson named the new genus, updated the description and named the new species combination in 1975.[2][4] They based the new species combination name on Cyril T. White's 1939 description of Orites racemosa, now a synonym.[1]
