 or rarely with two branches, veinlets slightly clavate at the apex not

GENUS LXXVIIL— T^ENITIS. (Willd.) 



(From tainia, a fillet or ribbon.) 



Veins reticulated, forming oblong hexagonal oblique areoles ; 

 sori linear, but the line sometimes interrupted, forming a transverse 

 band between the midrib and margin ; fronds adherent to the caudex. 



1. T.-enitis blechnoides. {Sw.) Rhizome creeping, setose ;

 8-12 inches broad, pinnate ; pinnae of barren frond 2-3 on each side, 

 1-2 inches broad, oblong-lanceolate, the point acuminate, the edge 

 thickened and wavy, the base cuneate, the lower ones stalked, fertile 

 pinnse more numerous and narrower, texture coriaceous, areoles

GENUS LXXIX.— DRYMOGLOSSUM. {Fresl.) 



(Drymos, wood ; glossa, tongue). 



Veins obscure, compoundly anastomosing in the sterile fronds, 

 forming 3-4 series of areoles between the midrib and the margin, 

 each including simple or forked free veinlets, with clavate apices ; 

 fronds articulate with the caudex, dimorphous, the sterile broad and
