G. hastata on Fée’s plates 18 f. 1—2 are confounded. — The veins of G. Rivoirei are 
not so upcurved as in typical D. Poiteana. 
D. Poileana has a wide distribution; it is found in most West-Indian islands 
and from Guatemala to Peru and Northern Brazil. I enumerate here some of the 
more important collector-numbers seen by me.

Perhaps a variely 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 pinne, which are gradually 
narrowed from the middle to the base (in D. Poiteana the pinn: have a short cu- 
neate or rounded base), and 3) by venation. Veins 8—-10-jugate, of which about 
the 8 pairs are meniscioid, but united under more acute angles than in the following 
species. Sori a little 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
