The poison-oak closely resembles the poison-ivy, and is sometimes called
by that name, but its leaves are differently shaped, being oval in
outline with a few coarse, blunt teeth. They are also thicker and
smaller than the ivy leaf. The poison-oak is plentiful in cool uplands
and in ravines, and is general throughout the Pacific coast from Lower
California and Arizona to British America.
