Toxicodendron orientale |
Toxicodendron orientale (Asian poison ivy) is an allergenic East Asian flowering plant in the genus Toxicodendron. The species was first characterized and named by Edward Lee Greene in 1905.[1] T. orientale is known to grow in Sakhalin, Japan, Taiwan, South central China, and South Korea. It was introduced to parts of Uzbekistan.[2]
Toxicodendron orientale is a climbing vine that grows on trees or other supports. The deciduous leaves of T. orientale are trifoliate and grow to be 3-10 cm in length. Young branches are covered with small brown hairs that turn into red lenticels as the branches mature.
T. orientale flowers from May to June. The small yellow-green flowers grow in groups from the leaf axils. The flowers mature into yellow-brown fruit in August to September.
All parts of Toxicodendron orientale contain urushiol, which is known to cause severe contact dermatitis.[3]
