Sori indusiate, linear-oblong or shorter and subltinate near the 

 eosta; the receptacles seated on the transverse anastomosing 

 veins. Jndimium plane or convex. Veins uniform ; the lower 

 ones arcuately anastomosing, forming elongated costal areoles 

 (one or more series) ; the marginal venules free. 



Fronds pinnatifid pinnate or pinnato-pinnatifld. Khizomo 

 short, erect or decumbent, or elongate creeping. — This genus has 

 considerable affinity, on the one hand, with the Lomariece, and 

 on the other with Brainea, which latter, on account of its short 

 transverse naked sori, we refer to MeniscieiB. The two groups 

 into which its species are disposed, have little to distinguish 

 them, the immersed and superficial sori being the principal 

 differences — characters which, in other instances, are not held 

 to be of generic value. 



§ Woodwcurdia. — Soriiimuersed; indusia vaulted, straight.

Sori non-indusiate, short, transverse, curved ; the receptaeles 

 seated on the arcuate costal veins, and often extending more or 

 less up the parallel oblique free venules j at length, irregularly
