In 1901, while visiting northern Europe, I found in the Botan- 
ical Garden at Upsala specimens of Potentilla pulcherrima Lehm., 
which had been cultivated for several generations since Lehmann’s 
time and kept unchanged the characters of pinnate leaves, etc. 
Side by side were growing also specimens of the so-called P. 
gracilis from Colorado with its digitate leaves. The latter is of 
course not the true P. gracilis but the P. pulcherrima of my 
monograph or P. pulcherrima communis Th. Wolf. Seeing these 
two forms together, the suggestion came to me that they might 
not be one species. While collecting in Utah, I found P. pul- 
cherrima in the same cafion where Dr. Watson had rediscovered 
it, viz., in the Big Cottonwood Cajfion, southeast of Salt Lake 
City. Here it was growing alone. Numerous specimens were 
seen in an open place along the river, but no digitate-leaved 
specimens were seen. I have come to the conclusion that it is 
not a parallel case to P. diversifolia, in which the basal leaves are 
either pinnate or digitate or both on the same plant. In all speci- 
mens of P. pulcherrima proper, the basal leaves are all pinnate, 
while in P. pulcherrima communis they are all digitate. In 19OI, 
I described a supposed new species under the name of P. jilipes, 
which Dr. Wolf reduced to a variety of P. pulcherrima. I have 
found that the characters separating P. filipes and the so-called 
P. pulcherrima of Colorado do not hold. I therefore united the 
two into one species under the name of P. filipes in the North 
American Flora. A depauperate high-mountain form of this 
species is P. pulcherrima condensata Th. Wolf. 
Professor Nelson in the New Manual of Botany of the Central 
Rocky Mountains makes not only P. pulcherrima and P. filtpes 
but also P. fastigiata and P. Blaschkeana synonyms of P. grace ’ 
a consolidation which goes altogether too far.
