Xeu. GEITESA OP FEESTS : 



sub-orbicnlar-reniform or transyersely oblong-reniform, plane, 



broadly af&xed at the posterior margin. Vein* stout, often 



thickened upwards, simple forked or pinnate, from a central 



costa; venules iiee. 



Fronds small, rigid, coriaceous, simple lobed pinnatifid or 



pedately-pinnatifid, or sub-temate. Sori usually rertical, rarely 



sub-terminal and oblique or sub-lateral to the yeins. Bhizome 



creeping, hirsntely scaly; or tufted (Imrayana.) — X characteristic 



group, with small coriaceous ironds, differing &om Acrophorm, 



in the broader base of the indusium. The DavalUa Imrayana 



of Hooker, an anomalous plant, appears to hare its place here, 



on account of its broad sub-reniform indusia. •

Sori indusiate, rotundate or transyersely oblong, intramarginal 

 or sub-marginal j the receptacles terminal or axillary on the yeins 

 or yenules. Indusium semi-orbicular, attached by the base and 

 sides, thus half-cup-shaped, the anterior margin free, truncate dir 

 rounded. Veins simple forked, or pinnate, from a central costa ; 

 venules direct free. 



Fronds herbaceous or sub-coriaceous, pinnate bi-pinnate or 

 decompound, the margin sometimes attenuated sub-membrana- 

 ceous and indistinctly crenated simulating accessory indusia.
