the most poisonous of the Sumachs. The name B. 

 Vernix, Linn., is used by some authors for this species 

 and by others for B. vernicifera; in order to avoid con-

 those proposed by DeCandolle.

 Tree-like, 20-30 ft. high: Ivs. ample; lfts. 11-15, smooth 

 above, pubescent beneath, midrib more or less broadly

 plant from which the Japanese obtain the lacquer for 

 the finely polished ware. It is poisonous, and it is said 

 that people have been poisoned by handling the articles 

 coated with the lacquer. Gn. 34, p. 158. -Cult. InS. Calif.

 slightly flattened, hairy, crimson. July, Aug. Eastern 

 N. Amer. to the Great Plains; succeeds well in dry 

 soils. S. 8.3:107-8. -This beautiful Rhus is the latest
