many. Leaves lanceolate, muticous or hyaline-pointed; muticous ones obtuse, 
entire; hyaline point short, somewhat denticulate, usually present on upper 
leaves of branches but sometimes wholly lacking throughout the plant; margin 
1 cell thick throughout. Upper opaque cells 1-4 times as long as wide, most 
of them elongated in the leaves having hyaline points; middle and basal cells 
1-2 times as long as wide. Dioicous. Calyptra long-subulate, slightly rough 
at apex. Seta 10-14 mm. long, twisted to the right, smooth. Capsule cylindric, 
erect, smooth, somewhat plicate when very old; body 3. 3-3. 8 mm. long; lid
