from A. flaccidum Fourn., based on ScHAFFNER nr. 85, 1877, San Luis Potosi (herb. 
Paris! PrinGLe nr. 11773 from Eslaba, Federal District, is probably the same. 
The species is perhaps not different from D. 
cinnamomea, with which it agrees by its small 
size, thin texture and large, grey indusia; it 
differs mainly by its deltoid lamina, lanceolate 
scales of the stipe and the less cut lamina; 
most pinnz are decurrent in a narrow wing 
to the rachis, and only the basal pinnules of 
the lower pinnz are free.

Perhaps a small form of the large D. 
patula var. Rossii. In the specimens leg. Ross indusia are clearly seen. The species 
resembles very much D. hirta and allied species of Ctenitis, but the venation and 
pubescence is that of Eudryopteris.
