Hab. Canada. Pursh. Saskatohawan. Drummond. — o. Slave Lake, Dr ^ Hichardson. — " There is," as Dr. 

 Boott justly observes, " great confusion about the heart-leaved Asters. Mr. Nuttallsays thdit A. paniculatus is 

 not distinct from A. undulatus, and that A. heteropliyllus is not distinct from A. cordifolius^^ Professor 

 Lindley remarks, upon one of my specimens from Dr. Short, of A. paniculatus^ that " it approaches A. 

 undulatus." The probability is that they are all forms of one and the same species; though I must observe 

 that I have myself seen noacknowedged undulatus and heterophyllus from British North America,
