In the Section Cyrtophlebium of Authors. 



To those who do not understand the botanical distinctions 

 between one genus and another, the Polypodium phyllitidis may 

 very naturally be called the Hart's-Tongue Fern of the Tropics, 

 as in the form of the frond it has some slight resemblance to 

 our Scolopendrium vulgare. 



An interesting and desirable species, yet one seldom to be 

 met with except in our larger collections. 



A West Indian Fern. 



The P . pilujllitidis is an evergreen stove species.
