brown colour, in age becoming confluent; a few hairs are intermingled 

 with the sporangia. 



This has more erect and slender fronds, with narrower segments, 

 and more numerous oblong sunken sori, than the preceding species. 

 Perhaps its nearest affinity is to P. rigescens of Bory, from which, 

 however, it is also very distinct.

Plant ccespitose, the roots near the surface of the ground producing 

 at irregular distances from the parent stock, small, scaly buds, which 

 ultimately form new plants by throwing out roots and fronds. Fronds
