nivalis forma nionstrosa, floril)us prolifeiis" of Oliver, about which 

 Hart, 1. c, p. 31, says, "may possibly be a variety of S. Virginiensis, 

 Mich.," is really this j)lant. 



It was in general found in wet places, in swamps, or in shady 

 localities among moss.

Engler, 1. c, p. 187, points out, that Linnaeus has understood by 

 his S. caespitosa both certain forms of that plant found in Scandinavia 

 which has afterwards usually passed under this name in our floristic 

 literature, as w^ell as the S. moschata, Wulf. which is commonly spread 

 in the Alps. As the name S. caespitosa is further used by different 

 authors, now for one, now for another plant, he deems it best to let the 

 ambiguous name S. caespitosa fall, and to use other names for the 

 two plants that Linnaeus united. This may be quite right, but in doing 

 so, he nevertheless, in my opinion, becomes guilty of two faults, viz., 

 for one thmg he uses the name caespitosa, L. for a sub-species of the 

 plant which he calls S. decipiens, Ehrh., for the other, he uses the
