142 Narrow-Leaved Chain-Fern 



soriferous. The petiole lengthens, and both petiole and rachis 

 become stouter and dark-colored. 



This fern is usually included in the genus Woodwardia, at 

 least in America, but appears sufficiently distinct to warrant 

 the restoration of Presl's genus Lorinseria, of which it is the sole 

 representative.
