tori are on a small, membranous, roundish cover, of 
which tbe edge is fringed with very long, taper, jointed, 
hair-like segments. 
This, one of the rarest of our Ferns, is found only on 
the highest and bleakest of our mountains It has not 
been found in Ireland. 
In England only on Falcon Clints, Teesdale, Durham. 
In Walet, at Glyder-vawr, near Lyn-y-cwm, and Clog-
