NOTES ABOUT THE DREPANOCLADI OF THE VICINITY OF MON- 

 TREAL, QUEBEC, CANADA 



H. DUPRET 



The Drepanocladi CM., formerly known as Harpidia SuU., are an interest- 

 ing and considerable section of the true Hypna with a decided preference for an 

 aquatic habitat. The contributions of the late F. Renauld to the Revue Bry- 

 ologique (1906-1909) and the works of Warnstorf and other German bryologists 

 have of late created a lively interest in these plants. Still, one may wonder why 

 they seem to be rarely collected, or at least rarely discussed in our reviews. May 

 we be allowed to offer an explanation for this seeming neglect? 



Drepanocladi, indeed, present peculiar difficulties to collectors, difficulties 

 which may be due to these two reasons : the plants are difficult of access, and not 

 very easily found. They grow, most of them, in wet meadows, marshy places, 

 or deep peat bogs. On this account a special outfit (as rubber boots) and a
