DESCRIPTIONS OF THE SPECIES 
251 
spreading segments, half line broad, toothed at the blunt 
apex. Stipe one to six inches long, slightly edged with 
green, and having scattered spreading scales. Fertile seg- 
ments longer, narrower, and more pointed. Sori linear, 
submarginal on each side of the segments, covered by a 
thin indusium opening inward. It seems to vary consider- 
ably in size, as some plants have fronds six inches high with 
as many as twenty-five segments one inch long, while other 
fronds on same plants are only one inch high with quarter 
inch long segments. Other specimens have similar medium- 
sized fronds, but along with them stronger fronds, divided 
into about sixteen segments three inches long. A specimen 
in Herb. Gub. has on a three-inch stipe a frond of nine linear 
segments, three to four inches long, and one line broad, the 
fertile infolded, not toothed at the tip, but sharp pointed.
