Populus x canadensis. CAROLINA POPLAR
SALICACEAE (Willow family)

Two trees at the main entrance to Green Library, on the south side of the Bing Wing, are reputed to be of this transatlantic hybrid species, as is a specimen to the right of Sigma Chi, 550 Lasuen Mall.

Poplars and willows are principal actors in phytoremediation, a technique of treating contaminated groundwater. Poisonous metals such as zinc, arsenic, and mercury are sought by the roots; as a consequence, removal of a few cubic yards of plant material offers an economic alternative to bulldozing thousands of cubic yards of contaminated soil.
