374 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



This is the common hright blue flowered vetch of the timbered mountains every- 

 where in the State. The leaf form varies greatly, the leaflets being from broadly 

 elliptic to narrowly linear-oblong. The name V. linearis is often applied to the 

 plants with very narrow leaflets, but the form does not appear to be constant, and all 

 intermediates are found, even in the same locality.

This has long been confused with V. pulchella, which it closely resembles in general 

 appearance. The flowers, however, are white instead of blue as in that species, and 

 much more numerous, while the peduncles are shorter and the calyx less pubescent. 

 Both species are found in the same region in the White Mountains, where they are at 

 once distinguishable in the field.
