Summer. 



To Dictyosiphon hippuroides we have referred the 

 common species of the summer, which com- 

 pares well with material and descriptions of 

 this form. It is, however, a puzzling species 

 which should be studied at other seasons of the 

 year to make certain its affinities. It seems 

 possible that this form may be a late seasonal 

 condition of Dictyosiphon fceniculaceus , very 

 common in this region in the spring.
