Hab. Northern States ! to sub-Arctic America! — We find 
no constant characters by which to distinguish C. vesicaria and 
amjndlacca. of American authors ; and we refer all our speci-

If the European C. amjnil/acca be distinct from C. vesicaria, 
ths two plants are certainly not generally understood nor 
feadily discriminated.
