Ruizia


Ruizia is a genus of flowering plants belonging to the family Malvaceae. It contains 13 species native mostly to the Mascarene Islands, and one species native to Madagascar.
The genus was described in 1786 by Antonio José Cavanilles, and named for Spanish botanist Hipólito Ruiz López. It was long thought to contain a single species, Ruizia cordata, endemic to Réunion. In 2021 the genus was re-circumscribed to include the genus Trochetia and several species formerly classed in genus Dombeya.
