House: Notes on New Jersey violets 257 



quite glabrous, but forms occur, and usually more abundantly, 

 which are more or less ciliate or even pubescent and it is often 

 difficult to determine whether the specimens under consideration 

 should be referred to K sagittatay to V. fimbriattda, or to some 

 hybrid form. 



The key to the species and varieties of violets of New Jersey 

 given below contains 33 species and varieties, of which 29 occur 

 in Middlesex County, and are indicated by a star. Further report 

 of thej hybrid forms will be made by President Ezra Brainerd of 

 Middlebury College, to whom they have been referred.
