The western form of .1. quitiquefolia L. is considered by Doctor Britton a distinct species, 

 but the apparent dilTerences are very slight. Our plant hivs been referred to as A. trifolia L., 

 and it is the basis of the "A. tetonewfis P(»rter?" in Suksdorf's list. Horner's 51 has dark 

 purple flowers and may 1h> di.stinct. 



Anemone narcirsielora L. is accredited to Washington by Torrey upon specimens col- 

 lettted at Port Di.scovery by the Wilkes expedition. The sp<>cimen in the National I lerbarium 

 is very young but it is not an Anemone. Apparently it is a Ranunculus, possibly an unusual 

 form of R. occidentalis Nutt.
