Populus nigra 'Italica.' LOMBARDY POPLAR. Asia
SALICACEAE (Willow family)
A tall narrow tree with branches growing almost straight up. The leaves are kite-shaped with finely toothed edges and flattened leaf stalks. The trees are genetically identical, cloned offspring of a male ancestor, propagated by cuttings that were brought to London from Tunisia in 1758 and introduced in Philadelphia in 1784. The roots will invade drain pipes or sewers if given a chance.
A group grows on Sand Hill Road at Saga Lane, Menlo Park, opposite the Stanford Linear Accelerator Center entrance.
