 not so upcuived as in typical D. Poiteana.

Perhaps a variety of D. Poiteana, which does not seem to occur in Mexico. 

 It differs 1) by its perfectly glabrous frond, which is rigidly membranous or sub- 

 coriaceous, 2) its crenate or very shallowly serrulate pinnæ, which are gradually 

 narrowed from the middle to the base (in D. Poiteana the pinnæ have a short cu- 

 neate or rounded base), and 3) by venation. Veins 8 — 10-jugate, of which about 

 the 8 pairs are mcniscioid, but united under more acute angles than in the following 

 species. Sori a litlle inframedial, small and not rarely oblong; sometimes 2 or even 

 3 sori are found on the same vein, and these being confluent the species resembles
