Viola palmata Britton 55 (in part). 



Frequent along the Coast strip and occasional in the Middle

This very distinct form of the cut-leaved group was first 

 recognized by Dr. N. L. Britton, Director of the New Yoi-k 

 Botanic Garden, formerly botanist to the New: Jersey Geo- 

 logical Survey, and author of the Catalogue of New Jersey 

 Plants, 1888. To Dr. Britton's example and encouragement, and 

 to the influence of his Illustrated Flora and Manual are mainly 

 due the development of the "new school" of botanists in North 

 America and the great advance in our knowledge of the flora 

 of. the Middle States, where he has been for many years a leader 

 both in the field and the herbarium.
