251. POISON IVY, POISON OAK (Rhus toxicodendron L.) an abundant, woody, high-climbing vine, often appearing shrubby when young, or in the absence of a support; preferring woodlands, but also in open places.

Branches: extending at right angles from main stem. Flowers: inconspicuous, whitish. Fruit: white, in small, loose clusters. All parts of the plant very poisonous to the touch: the apparent immunity of some persons may be lost at any time and those who have suffered previous attacks seem more subject to the poison thereafter.
