uniform reticulated ; the venules anastomosing in sub-equal hex- 

 agonal areoles, without included free veinlets. 



Fronds pinnate, dimorphous ; the pinnse articulate, the fertile 

 contracted, their whole margins sporangiferous. Ehizome scan- 

 dent. The specimens to which this name has been given, may be 

 abnormal semi-contracted fronds of some species of Newro- 

 callis, with which this agrees in everything except that it has 

 marginal linear sori ; it especially approaches our Chorizopteris 

 of that genus.

(c) Veins uniform reticulated, with included, free veinlets.

Sori non-indusiate, linear, continuous ; the receptacles margi- 

 nal or sub-marginal, superficial or slightly immersed. Veint 

 uniform reticulated, obscure ; the venules anastomosing in 

 roundish or oblong hexagonal areoles, from which proceed free 

 included simple or hamate obtuse veinlets. 



Fronds simple, dimorphous, or contracted at the fertile apex, 

 usually coriaceous. Rhizome creeping.

Sori non-indusiate, superficial, of two kinds : (1) linear, con- 

 tinuous, seated on a sub-marginal receptacle; and (2), roundish 

 or oblong, irregular, the receptacle seated on the short anasto- 

 mosing venules, or the recurrent veinlets. Veins uniform, re-
