Sphalmium is a monotypic genus of flowering plants in the protea family.[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, Satin Silky Oak and Buff Silky Oak.[3][5]

The tree grows to 30 m (100 ft) or more. It is endemic to the upland rainforests of the wet tropics region of north-eastern Queensland, Australia.[2][3][5]

History

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]
