The name Cyathocalyx was erected as a genus in 1855 by Joseph Dalton Hooker and Thomas Thomson.[2] Since then the delimitation of the genus has proved problematic, with various taxonomists proposing different assessments of the scope of the genus. In 2006 Rui Jiang Wang and Richard M.K. Saunders reduced the size of the genus from the then 36 species to 15.[3] The genus was further reduced in 2010 to just seven species.[4]
