 DICTYOPTERIS. Presl. Tent Pterid. 194. 

 (Dietymia, J*. Smith ;— Polypodii sp., Auct. ;— Drynariae sp., Fee. ;— Aspidii sp., Blum ;— Phegopteridis sp., Mettenius) 



Gen. cliar. Sori non-indusiate, globose or oblong, compital, I e., the receptacles uniting several radiating reticulated veinlets, 

 or medial. Veins uniformly reticulated (or sub-pinnately branched) from a central costa, the areoles elongated, oblique, without free 

 included veinlets* 



Fronds coriaceous or sub- coriaceous, simple or bi-pinnate. Sori sometimes marginally serial. Rhizome creeping (% always). 



The nearly uniform venation, without included free veinlets, distinguishes this genus. (Moore.)

 inferior ones much elongated and acuminated, the basal ones again lobato-pinnatifid, intermediate pinnae ovato-lanceolate pinnatifid, 

 terminal pinna long petiolate broad-ovate acuminate deeply pinnatifid especially at the base, veinlets uniformly reticulated, areoles with
