This is a rare tree in western Hupeh and Szech'uan where it grows only at low 

 altitudes. It yields no varnish and in western China the fatty oil is not extracted 

 from the fruit as it is in Japan. The bark is gray, rather thin and irregularly 

 fissured. The tree is shapely in habit and its glossy, rather coriaceous leaves in 



autumn assume a very fine color. 



From the description, native name and distribution it is highly probable that 

 Augia sinensis Loureiro {Fl Cochin. 337 [1790]) belongs here. Rhus succedanca 

 has been mistaken by some of the older authors for the true Varnish tree, R. ver- 

 niciftua Stokes.

This is a rather variable species; our specimen agrees very well with Franchet 'a 

 description except that the inflorescence is rather longer. In Honry s specimen 



longer.
