 ortly and regularly undulate or lobed, the apices of the lobes, which are 

 oader than ileep, dilated Texture ± coriaceous ; veins of the barren 

 nnae nearly straight, "parallel, close, simple or forked, those of the fertile 

 es oblique, curved, branched in the lobes. Sori n)arginal, 1 to each lobe, 

 liting the 2 — 3 branches of each vein; indusia 2 valved, firm-membrana-
