No specimens of the above species have been available for study, and as 

 the descriptions of the authors deal principally with vegetative characters 

 their status can not be definitely determined at this time. 



Micranthes eriophora (S. Wats.) Small appears to be very different 

 from any species described in this paper, but the specimen at hand is in 

 such poor condition that no definite conclusions can be drawn from it. 



Saxifraga gaspensis Fernald was separated by its author from Saxi- 

 fraga nivalis. The distinguishing characters as pointed out by Fernald 

 appear, however, to be wholly vegetative. 



Micranthes apetala (Piper) Small is probably a form of Saxifraga 

 nidifica Greene. 



This monograph was undertaken at the suggestion of Dr. C. O. Rosendahl, and 

 has been carried out under his direction. The writer was privileged to use the large 

 collection of Saxifragas in the Herbarium of the University of Minnesota, and other 

 large and valuable collections kindly loaned by other herbaria. 



The writer desires to express his thanks to Dr. Rosendahl for much needed advice, 

 for his efforts in securing valuable herbarium materials, and providing ample facilities 

 for carrying on the work; to Dr. Frederic K. Butters for much practical advice, help- 

 ful criticism, and information about the Saxifraga flora of the Selkirks and the
