linear, opening along the inward side. Veims (sterile) ; simple 

 or forked from a central oosta ; veimlea direct, &ee, thickened 

 at the apex; in the fertile fronds combined near the base or 

 within the margin by the receptacle. 



iPronds simple pinnatifid or pinnate ; the fertile sometimes 

 more or less contracted. Ehizome short, erect, or producing 

 elongated creeping stolones. — This genus is only intelligibly dis- 

 tinguished from I/omaria by including in it all those species 

 in which the indusia and sori are eyidently intramargiual, irre- 

 speotire of the contraction of the fronds,

Sori indusiate, linear, continuous, on a transyerse receptacle, 

 approximate to the costa. Imhtsmm broad, membranaceous, in- 

 volutely-cyUndraoeous, the opposite valves joined over the costa; 

 at length opening along the centre. Vems forked from a central 

 oosta ; venules parallel, combiued at the apex by a slight intra- 

 marginal veinlet, and near the base, (in the fertile fronds) by the 

 receptacle. 



Fronds bi-pinnate, scandent. Rhizome as in SlecTmam ? — Very 

 little different from JSlechnmn, except in the scandent habit and 

 combined venules. There appears to be but one species.
