Rhus Verniciflua
''Toxicodendron vernicifluum'' (formerly ''Rhus verniciflua''), also known by the common name Chinese lacquer tree, is an Asian tree species of genus ''Toxicodendron'' native to China and the Indian subcontinent, and cultivated in regions of China, Japan and Korea. Other common names include ''Japanese lacquer tree'', ''Japanese sumac'', and ''varnish tree''. The trees are cultivated and tapped for their toxic sap, which is used as a highly durable lacquer to make Chinese, Japanese, and Korean lacquerware. The trees grow up to 20 metres tall with large leaves, each containing from 7 to 19 leaflets (most often 11–13). The sap contains the allergenic compound urushiol, which gets its name from this species' Japanese name urushi (); "urushi" is also used in English as a collective term for all kinds of Asian lacquerware made from the sap of this and related Asian tree species, as opposed to European "lacquer" or Japanning made from other materials.

Toxicodendron Vernicifluum 03
''Toxicodendron'' is a genus of flowering plants in the sumac family, Anacardiaceae. It contains trees, shrubs and woody vines, including poison ivy, poison oak, and the lacquer tree.

The generic name is derived from the Greek words τοξικός (''toxikos''), meaning "poison," and δένδρον (''dendron''), meaning "tree". The best known members of the genus in North America are poison ivy ''(T. radicans)'', practically ubiquitous throughout most of eastern North America, and western poison oak ('' T. diversilobum''), similarly ubiquitous throughout much of the western part of the continent. The genus is a member of the ''Rhus complex'', and has at various times been categorized as being either its own genus or a sub-genus of ''Rhus.'' There is evidence which points to keeping ''Toxicodendron'' as a separate monophyletic genus, but researchers have stated that ...
