Which genus of plant had more species identified with it in the past, Carissa or Aruncus?
Carissa Carissa is a genus of shrubs or small trees native to tropical and subtropical regions of Africa, Australia and Asia. Until recently about 100 species were listed, but most of them have been relegated to the status of synonyms or assigned to other genera, such as "Acokanthera".
Stylogyne Stylogyne is a genus of shrubs and trees in the family Primulaceae. Its members are found throughout tropical parts of the Americas, with the greatest diversity in South America. It is closely related to the genera "Ardisia" and "Geissanthus", and various species have been transferred between the three genera. All three were formerly placed in the family Myrsinaceae, which is now treated as a subfamily (Myrsinoideae) of the Primulaceae.
