 moistened squarrose, curved from the ovate base, narrow, long-subulate, 

 nearly smooth ; borders reflexed nearly all around ; lower basaFcells 

 rectangular, more pellucid than the other ; costa reddish, percurrent 

 or short-excurrent. Inner perichetial leaves broad, blunt with a long- 

 excurrent costa, the other acuminate, all faintly crenulate. Capsule
