dentate; perichaetial leaves longer and more upright 

 than the cauline, closely adpressed to the base of the 

 calyx, which is three times their length. Perigonia in 

 short slender spikes, usually terminal, of a brown colour, 

 the leaves minute, tumid at the base and closely imbri- 

 cated. The P. hiserialis ofJJind. and Lehm. approaches 

 nearest to our plant in habit, but is far more slender, 

 has the leaves smaller, and their teeth larger.
