The western form of A. quinquefolia L. is considered by Doctor Britton a distinct species, 

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

 and it is the basis of the "A. tetonensis Porter?" in Suksdorf's hst. Horner's 51 has dark 

 purple flowers and may be distinct. 



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

 lected at Port Discovery by the Wilkes expedition. The specimen in tlie National Herbarium 

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

 form of R. occidentalis Nutt.
