Which genus between Borago and Banksia has the greatest number of species within the genus?
Banksia Banksia is a genus of around 170 species in the plant family Proteaceae. These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes and fruiting "cones" and heads. Banksias range in size from prostrate woody shrubs to trees up to 30 metres tall. They are found in a wide variety of landscapes; sclerophyll forest, (occasionally) rainforest, shrubland, and some more arid landscapes, though not in Australia's deserts.
Boraginoideae Boraginoideae is a subfamily of the flowering plant family Boraginaceae, as that family is defined in the APG III system of classification for flowering plants. The Angiosperm Phylogeny Group has not actually specified subfamilies within Boraginaceae. Some taxonomists place the genera "Codon" and "Wellstedia" in Boraginoideae. Others place one or both of these in separate, monogeneric subfamilies. "Codon" was long regarded as an odd member of Hydrophylloideae, but in 1998, a molecular phylogenetic study showed that it is closer to Boraginoideae.
