BRITISH HEPATIC^. 81 



Nor can the newly-proposed name gracilis be considered a happy one ; the shoots 

 are longer and more slender than in S. nemorosa, but the adjective expresses badly 

 the habit of a plant which Smith termed " crisped and turgid," and Hooker " crisped 

 and inelegant." Suppose it necessary to change the name, Hooker's term " recurvi- 

 folia " would be better, not to mention Dumortier's old synonym " dentata." 



Space will not permit me to pursue the subject further, but enough has been 

 adduced to show how much doubt envelops the question, and to tamper with names 

 which have been current for more than a century, except on the clearest evidence, 

 seems to me something more than a mistake.

 shoimng the reflexed lobes. 8. Apex of fertile stein seen from below, mth the colesule
