Which genus between Borago and Banksia has the greatest number of species within the genus?
Borago Borago, or borage, is a genus of five species of herbs native to the Mediterranean, with one species, "Borago officinalis" cultivated and naturalized throughout the world.
Banksia rufa Banksia rufa is a shrub endemic to Western Australia. It was first published by Carl Meissner in 1855, where it was given the name Dryandra ferruginea by Richard Kippist. The following year, Meisner published what was purportedly a distinct species, "Dryandra runcinata". In 1870, George Bentham maintained "D. runcinata", but demoted "D. ferruginea" to a variety of "Banksia proteoides" (King Dryandra). This stood until 1996, when Alex George restored the specific rank of "D. ferruginea", and declared "D. runcinata" its synonym.
