A List of Species of the smaller herbaceous Genera of North 
American Saxifragaceae, 
By Wo. E. id cecoropits 
In studying the Socasanng: North Asoesicnin Saxifragaceae, it 
has seemed desirable to present a preliminary enumeration of the 
Species, with their synonymy and distribution as known to me at 
_ the present time, with-a view of eliciting comment and to request 
additional material for examination. The species of Saxifraga 
_ will be enumerated by Dr. Small in a subsequent contribution. 
The genera have been taken up in the sequence adopted by 
Professor Engler, in Engler und Prantl’s ‘‘ Naturliche Pflanzen- 
familien,” and I find myself able to seit with him in most of his 
generic limitations. 
The following key will serve to indicate these limitations, 
The synonymy is given only for those species not enumerated 
_in the “List of Pteridophyta and Spermatophyta of Northeastern 
_ North America,” Mem. Torr. Club, §: BA spiionde 1804: a
