and we do this with the less reluctance, because we cannot 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 Grammitis with Gynvnogramma* genera by 

 no means too distinct, and only definable by giving its (Jue 

 prominence to the forked sori of the latter. 



Chilvpteris. Fronds small, simple forked or pinnatifid, rigid or thin 



coriaceous. 

 Ex. : G. Billardieri, Willd. \ G. marginella, Sw. 



G. myosuroides, Sic. G. furcata, Hk. and Gr. 



G. blechnoides, Grev. \ G. orgauensis, Gardn. 



Lepichroa. Fronds small, pinnate, densely scaly beneath. 

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

 Leptogramma. Fronds larger, compound, i.e., pinnato-pinnatifid, her- 

 baceous ; spore-cases often echinate. 



Ex. : G. aurita, Moore. \ G. aspidioides (Ceterach, Willd.) 



G. Hewardii, Moore. G. totta, Presl.

XlPHOPTEBIDIS 8p., Allot. 



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 sub-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. 

 Rhizome short, erect. Small plants, with a tendency towards 

 polypodioid structure. 

 Ex. : C. cucullatus, Prel. \ ? C. denticulatus (Grammitis, SI.) 



(b) Veins connivently anastomosing lelow.
