SpeciesThe Plant List, genus Athroisma
species of homonym genus William Griffith in 1854 used the same name for a genus of very different plants, thus creating an illegitimate homonym. The World Checklist categorizes his name as a synonym of the genus Trigonostemon in the Euphorbiaceae, but makes no mention of the two species names he coined. The Plant List does list the species as unresolved, i.e. of unknown application. The two species names areGriffith, William. 1854.
