Joannesia is a genus of plants in the family Euphorbiaceae, first described as a genus in 1798.[2][3] The entire genus is endemic to Brazil.[1][4]
- Species[1]
- Joannesia heveoides Ducke - Amazonas State in Brazil
- Joannesia princeps Vell. - eastern Brazil (Distrito Federal, Espírito Santo, Minas Gerais, Rio de Janeiro)
- species in homonymic genus
In 1807, Persoon used the same name, Joannesia, to a very different plant.[5] He thus created an illegitimate homonym, contrary to the rules of nomenclature. So the one species name that he had created in this illegitimate genus had to be renamed, as follows:[6]
- Joannesia insignis Pers. - Chuquiraga jussieui J.F.Gmel.[7]
