Lombardy poplar Populusdilatata

The Lombardy poplar (P. dilatata), a native of the banks of the Po, where it is sometimes called the Cypress poplar, from its resembance to that tree, is too well known among us to need any description. Only one sex, the female, has hitherto been introduced into this country; and it has consequently produced no seeds here, but has been entirely propagated by suckers from the root.
