DICRANACE^E.] io6 [Dicranella. 



The adoption of the genus Anisothecium enables us to retain the specific 

 name crispum for this plant, which otherwise would have to give way to 

 Dickson's and be termed D. vaginalis, for Dicranella Schreberi was named 

 crispum seventeen years before the present plant was known.
