Are Billardiera and Calothamnus both types of genuses?
Billardiera Billardiera is a genus of small vines and shrubs which is endemic to Australia. The genus was first formally described in 1793 by botanist James Edward Smith who named it in honour of Jacques Labillardière, a French botanist.
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.
