The Arbutoideae are a subfamily in the flowering plant family Ericaceae. Phylogenetic analysis supported all genera of the subfamily as monophyletic, except Arbutus.[1] Moreover, it was suggested that the sister relationship between Mediterranean and North American species may be explained by a once widespread distribution in the Northern hemisphere before the Neogene.[1]
The genera Arbutus, Arctostaphylos, Comarostaphylis form a particular type of mycorrhizal symbiosis with fungi resembling ectomycorrhizas; it is termed arbutoid mycorrhiza.[2][3]
