50 POLYPODIUM DIVERGENS. 



Rachis above furrowed, and densely pubescent. 



Stipes sparingly scattered with scales. 



Sori circular, medial; veins pinnately forked. 



The form of the frond is so similar to that of P. effusum, 

 that an ordinary observer would with difficulty find out the 

 difierence. In P. effusum the serratures are scarcely acute. The 

 rachis above scarcely pubescent, and the stipes, especially near 

 the base, is densely covered with scales. 



P. diver gens is a more tender species, the fronds paler and 

 more yellow in colour, and the pinnules are short and deeply 

 divided. 



Length of frond four to five feet. 



My thanks are due to Mr. Smith, Curator of the Royal 

 Gardens, Kew, for a frond of this species. 



It is not in the Catalogues of any of our Nurserymen. 



The fronds are proliferous; it is therefore very readily 

 propagated. 



The illustration is from Mr. Smith's frond.
