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 Genm 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 Columbia: 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 18 13. 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 

 59- 



New Mexico: Mogollon Mountains, 1903, Metcalfe 536. 



Colorado: Rico, 1898, Crandall 410Q.
