Professor Fernald has shown (Rhodora, 15: 182, 1913) that the com- 

 mon Prunella in New England differs from the European P. vulgaris 

 in the character of the principal cauline leaves (the median ones). 

 In the European plant these leaves are ovate or ovate-oblong, rounded 

 at the base, averaging one-half as broad as long. This plant is found 

 occasionally in lawns. In the common Prunella of the fields and road- 

 sides the principal cauline leaves are lanceolate to oblong, gradually 

 narrowed or cuneate at base, averaging one-third as broad as long.
