It seems only to create perplexity, to attempt to describe or 

 particularize the innumerable modifications of this polymorphous 

 species, which in reality have no definite limit, and arise from 

 local circumstances of climate, humidity, &c. They may be all 

 readily referred to the following varieties, by careful attention to 

 the prominent character. 



Var. vera pyxidata, podetia continuously corticate, granvlato- 

 verriwose.
