Genus 25. Ceropteris Link. 
Sori following the outer veinlets, simple or forked, without 
indusium. Under surface coated with white or yellow powder; 
frond (in our species) four-pinnatifid. Seven species, formerly 
included in Gymnogramme, confined to America, except as 
under. As mentioned in dealing with Gymnogramma, the 
species we have described under that genus seem to belong 
here.

Cl 
Plate 88. Nat. size, b P'ertile pinnule, enlarged. 
Crown erect, tufted, paleaceous, the young unrolled fronds 
clothed in yellowish scales. Fronds numerous, firmly herba- 
ceous, ovate-deltoid, acuminate, three-pinnatifid below, two- 
pinnatifid above, glabrous on the upper surface, coated with 
yellow powder on the under surface, one to one and a half feet 
long, five to seven inches broad at the base, with a furrowed 
brown stipe six to twelve inches long, which is dusted with 
white powder, and more or less paleaceous toward the base, 
with lanceolate spreading scales. On old fronds the powder 
is often absent from the stipe, and sometimes also from 
the under surface, except among the sori. Rachis furrowed, 
slightly green-margined. Pinnae lanceolate, widest at the 
base, distinct, and shortly stalked, except the upper ones 
which are slightly connected at the base. Lower pinnae two 
to three inches long, one inch broad, cut to the mid-rib into 
separate sessile, ovate-oblong, pinnatifid pinnules. Pinnae 
above the middle of the frond, cut to the mid-rib only at 
the base into ovate obtuse, toothed or nearly entire pinnules.
