This new species is closely related to D. melanosticta, agreeing with it in shape 
of lamina and basal pinne, it differs by its scales of stipe and rachises, which are 
bright reddish-brown, very narrow, hairlike and flaccid,-often intertangled; the basal 
scales form a rather large tuft as in D. ampla and they are similarly soft and wool- 
like. The distant secondary and tertiary pinnulz give the leaf a habit rather different 
from that of D. melanosticta, and the upper pinnules are longer decurrent. Bullate 
scales may be found on the midribs of the pinnules, but they are very few and small. 
The lamina is much less glandular beneath than most forms of D. melanosticta.

In Index Filicum -I have followed Kunn in identifying N. Grisebachii Bak. 
with A. ameristonevron Fée, now I have my serious doubts as to this being well 
founded. Fér’s description does not agree very well with N. Grisebachii; the seg- 
ments are described as »ovoides« and the leaf as having a »teinte générale brunatre¢; 
this last character, although rather unreliable, fits D. ampla, not D. Grisebachii. FEE 
quotes no collector but the locality »Cuba« only; probably he has here committed 
_ an error. On a label in Herb. Mett. (B) MrTreNius has written: »Aspidium ameri- 
-stoneuron Fée ined. Mexico. Tabasco. 1489. JuRGENSEN. I have no doubt that MET- 
-TENIUS’ note is right, that the species of F&E is really Mexican; from Mexico I do 
not know any form that with certainly may be referred to D. Grisebachii. 
_D. Grisebachii is intermediate between D. meridionalis and D. ampla. In size,
