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.
Lauraceae Lauraceae are the laurel family, that includes the true laurel and its closest relatives. This family of flowering plants comprises about 2850 known species in about 45 genera worldwide (Christenhusz & Byng 2016 ). They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as "Sassafras", are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. "Cassytha" is a genus unique to the Lauraceae family in that it is a genus of parasitic vines.
