Sort non-indusiate, oblong or linear, oblique; the elongate 

 receptacles lying between and parallel with the primary veins. 

 Veins pinnate or sub-pinnate from a central costa ; venules oom- 

 poundly anastomosing, producing within the areoles variously 

 directed free curved veinlefs. 



Fronds simple, rarely pinnatifid or palmately-lobed, herbaceous 

 or coriaceous. Ehizome creeping. — Separable from Loxogramma 

 by the pinnate character of the venation.

Sori spuriously-indusiate, marginal, oblong ; the receptacles 

 oblong at the apices of the veins, contiguous ; the spore-cases 

 laterally confluent and forming a broadish marginal band. 

 Indusivm, (spurious) formed of a narrow continuous attenuated 

 inflexed portion of the margin. Veins simple or forked, from a 

 central costa ; venules parallel, free, soriferous along a portion of 

 their length at the upper end. 



Eronds pinnate or bi-pinnate, coriaceous or sub-coriaceous, 



often glaucescent, the pinnse sometimes articulated. Stipes often 



ebeneous. Bhizome short, decumbent or creeping. — This genus 



unites the FlatylometB with the Qymnogrwm/metB, through Btero- 



zonium. We do not find in it any afEnity with the Fteridea, 



among which it is often placed.
