 Found on the Continent. 



Obs. — Since Hooker's time there has been considerable doubt 

 as to whether this form should rank as a species or not. In his 

 "Brit. Jung." it is published as a variety oi S. nemorom, but from 

 this it is distinguished by the shape of its leaves, which are also 

 only denticulate, not ciliate, in many respects approaching 

 S. undidata. Dr. Gottsche, writing to Dr. Carrington many 

 years ago, said : " I cannot yet define the limits of these species 

 {S. nemorosa and S. nndidala^ and if I believe myself for a time in 

 order with the genus, new forms confuse me again." 



It appears to occupy the same position between S. imdidata and 

 S. nemorosa as S. infer media, Husn., does between S. jj/frj}ifraseeii-s 

 and S. nmhrom.
