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]

Etymology

Joannesia is a taxonomic patronym honoring the king John VI of Portugal.[5]

The name Joannesia yielded a taxonomic anagram for the confamilial genus Annesijoa.[5]
