Eu. to W. and N. Asia. —One of the most important timber trees of Eu. It is quite hardy, but has little to recommend it as an ornamental tree.

Var. nivea, Schwerin. Lvs. a dirty greenish white. Var. Beissneriana, Schwerin. Lvs. green at first, changing to golden yellow in summer. Var. colum- naris compact;!, Bailly.
