and we do this with the less reluctanoe, tecause we oannot as a 

 principle, admit, that the habit and aspect of a species should 

 override obvious characters of the fructification, in determining 

 its genus. In this instance, the compound-fronded species, are 

 the link connecting Chrammitis with Oym/aognlm/ma — genera by 

 no means too distinct, and only definable by giving its due 

 prominence to the forked sori of the latter. 



§ Chilo-pterin. — Fronds smaJI, simple forked or piunatifid, rigid or thin 

 coriaceous, 



Ex. ; G. BUlardieri, Willd. I G. marginella, Sw. 



G. myosuroides, Siv, G. fiircata, J£k. and Gfr. 



G. blechnoides, Ghev. \ G, orgauensis, Ga/rdn. 



§ Lepichroa, — Fronds small, pinnate, densely scaly beneath. 

 Ex. : G. capensis (Ceterach, Kze.) | G. cordata, Sw. 

 § Leptogramma. — Fronds larger, compomid, i.e., pinnato-pinnatifid, her- 

 baceous ; spore-cases often echinate. 



Ex. : G. aurita, Moore. .

Sori non-indusiate, oblong (or sub-globose), solitary; the 

 receptacles seated at the thickened apices of the simple vein 

 which occupies each lobe, the margin of the lobe being longitu- 

 dinally folded Bub-cucullately over the sorus, in the manner of 

 a spurious involucre. Veins simple. 



Fronds small, fasciculate, thin, somewhat rigid, pinnatifid, the 

 lower barren lobes longer, the fertile folded longitudinally. 

 Ehizome short, erect. — Small plants, with a tendency towards 

 polypodioid structure.
