DOUGLAS' HACKBERRY Celtis Douglasii Flanchon This tree inhabits river valleys in Idaho, Oregon, Washington, and British Columbia, south to Utah cind Colorado, and much re- sembles the Thick-leaved hackberry of the southwest, with which it has been confused, and it is also closely related to the eastern Celtis occidentalis.

The leaves are ovate to ovate-lanceolate, 10 cm. long or less, pointed, often long-pointed, rough above, rather strongly netted-veined beneath; their stalks are hairy and short, usually not more than 6 mm. long.
