 or pyrlform, cernuous, horizontal or pendent, very rarely erect. 

 Peristome generally double; teeth transversely barred; inner mem- 

 brane divided into segments alternating with the teeth, generally 

 separated by cilia.

 with nodose articulation. 



Leaves narrow, subulate. Capsule long- 

 necked. Peristome double. Cilia appen- 

 diculate.

 olation narrow, linear-hexagonal. Capsule 

 short-necked. Inner membrane broad ; cilia 

 smooth.

 tire; cilia none or very short. 



Cellules of the areolation rhombic-hexagonal, 

 loose, solid. Capsule pyriform, mostly reg- 

 ular. Teeth of the peristome lobed; seg-
