compared with those of Thuret on the im- 

 pregnation of the spores in Fucus. Little 

 is known of exotic species, as it is scarcely 

 possible to recognise them from dried 

 specimens, which lose all their distinctive 

 characteristics. [M. J. B.]

 proposed by Herbert for Barbacenia sqva- 

 mata. It has since been applied by Dr. 

 Lindley to a curious Japanese conifer, of

 now been shown by Professor Oliver to be 

 nothing but a monstrous condition of 

 some Japanese conifer, the name of which 

 has not been yet ascertained. [T. M.]
