In 1696, Leonard Plukenet called a plant he found in Jamaica Euphrasia, affines majori folio (similar to Euphrasia but with larger leaves). Linnaeus ([1753] 1957) called it Justicia sexangularis. Both of those genera are other members of the family, but these herbs did not actually belong to either one. Then, in 1807, Jussieu moved Linnaeus’s species to create Dicliptera sexangularis. Today, there are 150 species in the genus (Mabberley 1997).
