Toxicodendron vernicifluum (Stokes) F.A.Barkley (synonym Rhus verniciflua) – Lacquer tree or varnish tree grows in Asia, especially China and Japan. Growing up to 20 m tall, its sap produces an extremely durable lacquer. The leaves have 7–19 leaflets (most often 11–13). The sap contains the allergenic oil, urushiol.
