486 RYDBERG: NOTES ON ROSACEAE 
oides of Meyer and the writer with pleasure dedicated it to the 
botanist who first distinguished it. It is strange that this species 
(or variety) of the Geum canadense group has not been recognized 
by any American authors. It was admitted and described also 
by Scheutz in his monograph.* It is related to G. canadense, 
but the basal leaves and lower stem-leaves are pinnatifid and the 
stem is more hirsute. These characters are sometimes found in 
G. hirsutum Muhl. [G. florum (Porter) Bicknell], but the petals in 
G. Meyerianum are white and longer than the sepals, while in G. 
hirsutum they are pale yellow and much shorter. 
The following specimens belong to G. Meyerianum: 
New York: Fleishmann, Delaware County, 1892, Hermann von 
Schrenk; Tuxedo, 1896, W. H. Lewis; Oneida, 1903, H. D. House. 
OnTARIO: Battersea, 1898, Fowler. 
QuEBEC: Danville, 1894, A. K. Berg. 
' PENNSYLVANIA: New Danville, Pike Crossing, 1901, Heller; 
Bangor, 1899, Porter; Easton, 1899, Porter. 
District oF CotumsiA: banks of canal, 1895, Pollard. 
Geum hirsutum Muhl. This species has been well characterized 
by Porter and Bicknell under the names G. album flavum and G. 
flavum. It-was also described by Fischer and Trautvetter, who 
mistook it for G. canadense, which they held distinct from G. album. 
The oldest name, however, is G. hirsutum Muhl. Muhlenberg 
listed it in his catalogue in 1813. In this publication it is to 
be regarded as a nomen semi-nudum, but nine years later Link 
gave it a short description, pointing out the essential characters. 
Geum decurrens Rydb. Some specimens from New Mexico, 
Arizona and Colorado and named G. strictum seemed so different 
from all other specimens of that widespread and rather variable 
species, that the writer thought it advisable to propose in the 
North American Flora a new species based on these specimens 
The essential characters are pointed out in that work. It is, 
however, advisable to cite some more specimens. 
Arizona: Bakers Butte, Mogollon Mountains, 1887, Mearns

NEw Mexico: Mogollon Mountains, 1903, Metcalfe 536.
