Toxicodendron rydbergii, the western poison ivy or northern poison oak, is a species of Toxicodendron in the cashew family native to North America.
Description
Unlike Toxicodendron radicans (eastern poison ivy), which often appears as a trailing or climbing vine, Toxicodendron rydbergii is a shrub that can grow to 1 m (3 ft) tall, rarely up to 3 m (10 ft). The leaves are trifoliate and alternate. The leaflets are variable in size and shape, and are usually 15 cm (6 in) long, turning yellow or orange in autumn. On the compound trifoliate leaves, the two leaflets opposite each other are typically asymmetrical, in contrast to the terminal leaflet which always shows bilateral symmetry. The fruits are small, round, and yellowish. Like other members of its genus, all parts of this plant contain urushiol, which can cause severe contact dermatitis in most individuals.
Distribution and habitat
It is native to most of Canada from the Maritimes to British Columbia, and most of the contiguous United States except the Southeast, Nevada, Oregon and California. It is apparently extirpated from West Virginia. It can be found growing in forests, and other wooded areas, usually near streams and rivers.
