the most poisonous of the Sumachs. The name J?. 

 I'ertiix, Linn., is used by some authors for this species 

 and Ijy others for ii'. veriiicifera: in ordt-r to avoid con- 

 fusion, it seems best to drop the name lunl to sulistitute 

 those proposed by DeCandolIe.

 brilliant fall colorii' 

 and the 7»ersistenc 

 of its crimson fruii 

 chisters render this 

 plant of great value where a 

 warm color effect is desired. 

 It will grow in the driest soils.

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

 plant from whicli the Japanese obtain the lac(|uer for 

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

 that people have been poisoned by handling the articles 

 coated with the la<-(iuer. (_in. 34, p." 158. -Cult. inS. Calif.

 has only one species, B. rcrficillatum, a plant not in 

 cultivation.
