The specimens referred to above are in the herbarium of the 

 New York Botanical Garden. 



The quotations from Professor Stone's letters give the history 

 of the introduction of the Austrian field-cress in Wisconsin. 

 Mr. Hansen's paper, referred to above speaks for New York, 

 The occurrence and firm establishment of the plant in these 

 States leads us to suspect that it may also be found in other 

 States and, perhaps, also in Ontario. The prolific and vigorous 

 underground stem-system, far surpassing that of any of our other 

 species of Radiciila will render it very difficult of eradication if 

 it becomes established.
