icil. GENEEA OF PEENS : 



sub-orbicular-reniform or transversely oblong-reniform, plane, 

 broadly affixed at the posterior margin. Veins stout, often 

 thickened upwards, simple forked or pinnate, from a central 

 costa; venulesfoee. 



Fronds small, rigid, coriaceous, simple lobed pinnatifid or 

 pedately-pinnatifid, or sub-ternate. Sori usually vertical, rarely 

 sub-terminal and oblique or sub-lateral to the veins. Rhizome 

 creeping, hirsutely scaly; or tufted (Imrayana.) A characteristic 

 group, with small coriaceous fronds, differing from AcropTiorus, 

 in the broader base of the indusium. The Davallia Imrayana 

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

 on account of its broad sub-reniform indusia.

Sori indusiate, rotundate or transversely oblong, intramarginal 

 or sub-marginal ; the receptacles terminal or axillary on the veins 

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

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

 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. 

 Rhizome creeping or tufted. A genus of large-growing herbace-
