Rootstoch creeping, long mid slender, branched, covered with brown 

 slender palese. Fronds entire, the under surface with a dense, stellate, 

 brownish-ichite pubescence, imparting a somewhat hoary aspect ; the 

 upper surface less so; the sterile fronds orbicular, ovate or ovate-oblong, 

 from one-fourth to nearly an inch in length, seated on a short stipe 

 usually about half the length of the frond itself; the fertile ones lance- 

 linear, obtuse, much attenuated at the base, from one to 2 inches long; 

 the stipe nearly of the same length. Sori scattered, crowded, and 

 becoming confluent.

 stellate pubescence.
