Autoicous ; in very lax soft pale yellowish green tufts, the stems 

 depressed, with distant irregular branches and a few short ramuli. Stem- 

 leaves glossy, lax, erecto-patent, narrow and slightly decurrent at base, 

 ovate, gradually extended into a subulate point, margin recurved at base, 

 feebly serrate, nerve yellowish f the length, cells laxer at base, quadrate 

 and hyaline at angles. Branch-leaves lanceolate, acuminate, sharply 

 serrate. Perich. bracts suddenly recurved and subulate from the middle, 

 faintly toothed, nerve slender. Seta purple, smooth, flexuose, capsule 

 longish cylindric, pale brown, curved, lid conic rostrate, peristome orange,

 mostly affects the vicinity of the sea.
