The family Anacardiaceae contains poison ivy, poison oak, poison sumac, and Schinus terebinthifolius, or Brazilian pepper-tree.

They have formerly been listed under genus Rhus and are often referred to as sumac in common speach: Toxicodendron radicans (Poison Ivy), Toxicodendron diversilobum (Poison Oak), Toxicodendron vernix (Poison Sumac).

Poison ivy, with its distinctive three-lobed leaves, either climbs trees as a vine or forms free-standing "bushes" 2-3 feet tall. The bush form is referred to as "poison oak.

Fortunately, the plants and animals are adapted to these conditions. Most of the plants have small, hard leaves which hold moisture. Some of these plants are poison oak, scrub oak, Yucca Wiple and other shrubs, trees and cacti.

In addition to the uses already mentioned a root decoction has also been use to treat rheumatism, bronchitis seizures, and as an anti-inflammatory. The Cherokee would "hold root ooze in the mouth for toothache" and rub leaves on poison oak rash.

If a climbing surface isn't available, poison-ivy will grow as a free-standing shrub that looks a lot like its relative poison oak (T. pubescens). The attractive white berries are 1/4 in (0.6 cm) in diameter.

Mangos may be pruned to control size in late winter or early spring without a loss of fruit. Sap and debris can cause severe dermatitis, similar to poison oak. It is best to avoid burning prunings or litter.
