The habit of this genus is characteristic. The leaves present a flattened 

 or complanate appearance. The habitat varies, they are to be found on 

 rocks, soil, or on trees. They vary also in size from small plants to those 

 of medium size. Capsules ovoid to cylindrical. Leaves costate, mostly 

 entire, acuminate, o\^ate or oblong, lanceolate, thin. Capsule slender or 

 suberect. Seta smooth. Stems irregularily branched, riot pinnate, 

 stoloniferous, loosely tufted yellow green. 



Three forms most often met are P. sylvalicum, slrlalellum, denticulalum. 

 In striatellum the plants are not complanate, the leaves are squarrose 

 spreading. In sylvaticum, the leaves shrink when dry, in denlicidatum 

 the leaves are asymmetric.
