In this species the root is a small disk, the stems 

 cylindrical, expanding into simple or forked flat 

 membranceous frondlets, often producing* a young- 

 frond at the extremity, which springs from a short 

 stalk. In appearance, the present species is not 

 very unlike P, riibens, but smaller and much more 

 delicate in substance, and readily known by its 

 being proliferous from the tips of the frond, instead 

 of from the surface, as in P. ruhc7is, " Nemathecia 

 large, globose, dark red, sessile on the tips of frond, 

 at length converted into strings of tetraspores,^^ 

 Grows on rocks. Rare. Perennial. Spring.
