glabrous, and "with the indusia largo and porsistent.

This specimen agrees witli Beddome's description, except that tlie stipe is 
longer and the pinnae broader, 
I have Iiitherto been disposed to regard M. poli/carpa as merely an abuiraiit 
Dryopteris unworthy of generic separation, but the study of this plant, so distinct 
in minor respects, although having in common the peculiar pubescence of paleae, 
hairs and glands, with the indusium character accentuatrd, makes it clear that 
MesoeliUuna is a small group with many characters, instead of a single peculiar 
species. It therefore seems desirable to continue to maintain the genus as a fixed 
and well-marked offshoot of Dryopteris. The two sides of the indusium are often 
unequal. By definition the genus can not easily 1k' distinguished from Athyritnn 
§ Callipteris, to which it is really not nearly related.
