brown or black, 1-3 inches high, some 
ped. Fronds scarcely a span long, extremely " 
lower pinne gradually becoming smaller, remote, 
bearing however sori, 
with a few short narrow segments, divided — 
from the very base, and spreading; upper ones much larger; 
more crowded, the segments also rather broader and more 
elongated, especially the ultimate ones. The cellular texture 
this is quite peculiar, so far as I know, among the Hymen0- 
phyllacee, and is best understood by our magnified figures. 
is so rem 
arkable that Pres] has therefrom constituted a new 
genus, Abrodictyum.
