VITTARIA. 14T 



GENUS VIII. 



VITTARIA. J. Smith. 



An interesting small tribe of plants, two species of which 

 have been introduced into this country. 



The fronds are simple, linear, and smooth. 



Habit pendulous. 



Veins simple, forming an acute angle with the midrib, and 

 having their apices prolonged into a transverse marginal vein, 

 which eventually becomes the sporangiferous receptacle. 



Sori marginal or slightly intramarginal, being a continuous 

 line, looking like the fructification of the Pteris without the 

 indusium.
