Which genus has more species, Cibotium 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.
Corvus Corvus is a widely distributed genus of medium-sized to large birds in the family Corvidae. The genus includes species commonly known as crows, ravens, rooks and jackdaws; there is no consistent distinction between "crows" and "ravens", and these appellations have been assigned to different species chiefly on the basis of their size, crows generally being smaller than ravens.
