The western form of A. quinguefolia Li. 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 list. 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 the National Herbarium 
is very young but it isnot an Anemone. Apparently it isa Ranunculus, possibly an unusual 
form of PR. occidentalis Nutt.
