Genus 24. Gymnogramma Desv. 
Sori oblong or linear, simple or forked, following the course 
of the veins, rising from them, and having no indusium. Veins 
free. Plant perennial, in our species three-pinnatifid. Forty- 
eight species are placed here by Christensen, mostly South 
American. In our first edition Gymnogramme was a wider 
genus, including several species now placed elsewhere. Baker 
(Syn. Fil}) includes G. argentea in his section Ceropteris, con- 
cerning which he says : “ Differs from Eu-gymnogramme only 
by the fronds being coated beneath with white or yellow 
powder.” Christensen restores Ceropteris as a genus, but 
includes our species in Gymnogramma though so coated. We 
follow Christensen only for herbarium convenience, but think 
if that be the only difference, both our species should be in 
Ceropteris. 
94. Gymnogramma argentea (Willd.) Mett. 
Plate 87. Nat. size, b Fertile pinnule, enlarged. 
Crown erect, slender, tufted, somewhat coated with white 
powder. Fronds herbaceous, fragile, deltoid, four-pinnatifid, 
green and glabrous on the upper surface, and on the under 
surface coated with white or pinkish powder, which is generally 
very abundant, but sometimes nearly absent. Fronds one 
half to two feet long, four to eighteen inches broad, with a
