THE FERN BULLETIN 



wrote me, that it is the form described by Druery in 

 "Choice British Ferns/' page 120, as bifid o-cristatum,

 prickly pear, sage-brush, grease- wood, and juniper — 

 a strange combination. Filix fragilis or Cystopteris 

 fragilis — which is it? — I found on a few occasions in 

 the deep wooded ravines which sometimes occur in the 

 regions. Two species of Equisetum were seen but not 

 identified. The species which is enclosed was very
