XIX. GENEEA OF FERNS : 



riferous one two deeper furrows in which the sori lie. Ehizome 

 creeping, scaly. Totally distinct from the Gymnogrammeee, and, 

 as it appears to us, from all the established genera of ferns. 

 Ex. : 0. pentagonus (Grammitis bisulcata, HooTc.) 



(b) Veins uniform reticulated, without free included veinlets.

PTEBOPSIDIS sp., Desvaux; DIGBAMHA, Kunze; PIEEIDIS sp., Auct ; Air- 

 TEOPHII sp., Auet. 



Sori non-indusiate, linear, continuous or interrupted; the 

 receptacles sub-marginal or medial, superficial or somewhat im- 

 mersed. Veins uniform reticulated, forming elongated longitu- 

 dinal or oblique areoles, without included free veinlets. 



Fronds simple lobate or pinnate, rigid ; the sori and costa in 

 T. nipkololoides, clothed with stellate hairs. Ehizome creeping. 



Ex. : T. angustifolia, Sr. I T. marginalia (Antrophyum, SI .) 



T. blechnoides, 8w. \ T.niphoboloides (Antrophyum, Kze .)

SCHIZOLOMATIS sp., Gaudichaud} IIHTDSXM sp., Auct.; DETMOGLOSSI 

 sp., Hooker. 



Sori non-indusiate, linear, continuous ; the receptacles sub- 

 marginal, immersed ; the interior thickened margin of the groove 

 elevated and sub-indusiform. Veins uniform reticulated; the 

 venules anastomosing in unequal elongated oblique areoles, with- 

 out included free veinlets. 



Fronds polymorphous, simple or lobed, coriaceous ; the fertile 

 more or less contracted. Ehizome creeping. A well-marked 

 genus, differing from ScMzoloma in the absence of an indusium, 

 and from Drymoglossum in the absence of free included veinlets. 



Ex. : S. cordatum, Fte. \ S. rigidum (Drymoglossum, We.)
