Life Cycle Comments
Long lived small tree, which repiroduces by seed.(a single seed held within a fleshy drupe). The species is bird dispersed and by gravity and is cold tolerant.
All members of the genus produce the skin-irritating oil urushiol, which can cause a severe allergic reaction. This is called urushiol-induced contact dermatitis (also called Toxicodendron dermatitis and Rhus dermatitis). In most cases rash symptoms appear within 24 hours. If a severe reaction occurs medical attention is needed to prevent damage to the skin. The rash may persist for up to one or two weeks (in some cases up to five weeks). One in four people are likely to experience severe symptoms. Since the skin reaction is an allergic one, people may develop progressively stronger reactions after repeated exposures.
