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.
Boisea Boisea is the least speciose genus of the soapberry bug subfamily. Members of this genus are found in North America, India, and Africa. Unlike other serinethine genera, the distribution of "Boisea" is very patchy; it is speculated that its highly vicariant range is relictual of what was previously a much vaster, continuous range. The most well-known species of this genus are the North American boxelder bugs (western "Boisea rubrolineata" and eastern "Boisea trivittata") and African "Boisea fulcrata". The US species mainly feed on the seeds of Maple trees and are occasional nuisance pests around homes.
