 have been overlooked, and, on the other hand, that soms changes 

 may not stand. 



The first name given is the corrected name, the last one the 

 name used in the manuals. In many cases I have found it nec- 

 essary to interpolate either the binomial under which the plant 

 was first described or such synonyms as will show the derivation 

 of the several names.

 sma Pursh. PI. Am. Sept. .385. (1814) 

 Anemone patens var. nuttalliana Qraj Man. Ed. 5 36. (1867) 

 Dr. Britton as well as the best European authorities, con- 

 sider Pulsatilla a genus distinct from Anemone.

 This plant has been referred to Thalictrum as well as to 

 Anemone. It is generally regarded as the type of a dis- 

 tinct genus, and should have the older generic name — Syn- 

 desmon.
