Which has more species Aeonium or Crowea?
Crowea Crowea is a genus of small evergreen shrubs in the plant family Rutaceae sometimes known as Waxflowers. There are three species and many subspecies and cultivars, all of which are popular as ornamentals because of their abundant, attractive flowers which often occur during autumn and winter. "Crowea" species are all endemic to Australia, where they occur in Victoria, New South Wales and Western Australia.
Euploea Euploea is a genus of milkweed butterflies. The species are generally dark in coloration, often quite blackish, for which reason they are commonly called crows. As usual for their subfamily, they are poisonous due to feeding on milkweeds and other toxic plants as caterpillars. The latter are aposematically colored to warn off predators from eating them, and the adult butterflies are often mimicked by unrelated species which are not or less poisonous.
