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, witli which it agrees by its small 



size, thin texture and large, grey indusia ; it 



differs mainly bj' its deltoid lamina, lanceolate 



scales of the stipe and the less cut lamina; 



most pinnæ are decurrent in a narrow wing 



to the rachis, and only the basal pinnules of 



the lower pinnæ are free.

Perhaps a small form of the large D. 

 patula var. Hossii. In the specimens leg. Ross indusia are clearly seen. The species 

 resembles very much Ü. hirla and allied species of Ctenitis, but the venation and 

 pubescence is that of Eiidryopieris.

 In Ark. for Bot. 9" : 43 I have said that T. cinnamomea Cav. probably is the 

 same as Asp. athyrioides M. et G.; now I have no doubt that the two names are 

 synonyms. I add here the original description of T. cinamomea Cav.

 ficationibus solitariis. f 



La planta es lampifia; los peciolos delgados, amarillentos; las hojas de color
