 countries. 



This plant, which is found scattered over various and di- 

 stant parts of the globe, and which may be met with in the 

 darkest woods as well as in open bogs, is liable to no small 

 degree of variation in size as well as in the direction of the 

 leaves. The larger variety, with more falcate leaves, has 

 been distinguished by the name of D. majus ; while on 

 the other hand the smaller plant, with leaves scarcely if 

 at all secund, has been called D. fuscescens. This last- 

 mentioned variety is scarcely to be known from D.Jlagel- 

 lare Hedw. but by its more curved and somewhat drooping 

 capsules.

HAB. On moist banks. 



After an attentive examination of numerous specimens of 

 D. varium and D. mfescens, we have considered it most 

 prudent to make them varieties ; for notwithstanding that 

 D. varium in occasional plants has the leaves decidedly fal- 

 cate, of a greener colour, a firmer texture, with an entire 

 margin, and its capsules inclining; while some individuals 

 of D. rufescens have their leaves of a reddish colour, with 

 an evident reticulation, serrated margin, and with erect cap- 

 sules 5 yet we have met with specimens partaking so much
