MEMOIRS FROM THE DEPARTMENT OF BOTANY OF COLUMBIA UNIVERSITY 45 



Most specimens of what has been regarded as P. rivalis millegrana from the Pacific States 

 belong to this species. In the original description the cyme is said to be "mostly con- 

 tracted and dense," but this is scarcely true except in a very young state. Later on it 

 becomes very long and racemose. The leaflets are crenate rather than incised. There 

 are two more or less distinct forms found, one with small leaves and much elongated in- 

 florescence, the original P. lateriflora, and the other with large leaves and less elongated 

 inflorescence. The latter served, if I mistake not, as the type of P. biennis. 



It ranges from British Columbia and Assiniboia to Arizona and Lower California.
