Tn silvas, 1,800 m. s. m. (No. 5949), 
This plant miglit, with equal reason, be assigned to Microlepia, or Denn- 
fitucdtia; I should have preferred to have called it Mlcrolepid, since that genus 
is at best undefinable, but its generic separation from Dennstaedtia flaccida would 
not be justifiable on any ground. Its probable relatives are Dennstaedtiofi of the 
D, flaccida group, Microlepia hirta and the so-called M. dennstaedtioides Copel.' ' 
with regard to which I am now prepared to accept Christ's judgment and call it 
Dennstaedtia, D. dennstaedtioides. 
I have come to the conclusion that Microlepia will have to be abandoned, as 
a genua, and regarded in the future as the primitive section of Dennstaedtia.
