G, agrimonioides (Pursh ?) C. A. Meyer. As to Pursh’s plant, 
Scheutz has overlooked the positive affirmation in Torr. and Gray 
Flora, that it is Potentilla arguta, as was long before suspected by 
Sasa 8 Scheutz has no authentic materials of this, but describes 
no white flowered species with densely pubescent receptacle, which 
is the special character of G. strictuwm, and none of the latter 
with petals oval instead of orbicular, and rather shorter than the 
calyx. Meyer’s plant lies between 'G.. strictum and G. album or 
Virginianum. It is to be noted that there is a Geum in Penn- 
sylvania, Ohio, &c., with greenish-yellow or yellow petals, but 
with the receptacle and mainly the other characte rs of G. album 
is we have once referred to G. urban ., and the question 
is whether G. albwm altogether should not be e referred, as i 
intimated in the last edition of the Manual.
