Arbutoideae

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 non-sister relationship between Mediterranean and North American species may be explained by a once widespread distribution in the Northern hemisphere before the Neogene.[1]

Genera

The genera Arbutus, Arctostaphylos, Comarostaphylis form a particular type of mycorrhizal symbiosis with the fungus Arbutoid mycorrhiza, which resembles ectomycorrhizas.[2][3]

gollark: In general, if you did a survey or something, I think you would find that people are annoyed by microcrafting. Also, sleep is important and you should do it.
