This comes perhaps nearest in general appearance to D. cris- 
pum ; but from that and all the other species which have little or 
no stem it differs in the perichztial leaves, which are remarkably 
| sheathing like D. scoparium and its affinities. It is from habit 
alone I judge it to belong to this genus; for I have seen no peri- 
stome, and the operculum is singularly short and obtuse, in this 
respect approaching that of Didymodon purpureum and some 
others.
