38 POLYPODIUM HARPEODES. 



Length from three to four feet; colour dull bluish green. 



Stipes nearly half the length of the frond. 



Veins much more indistinct than in P. CatJiarince. 



Sori uniserial, large, and yellowish brown in colour. 



For fronds of this species my thanks are due to M. Schott, 

 of the Imperial Gardens of Vienna, and to Mr. J. Smith, curator 

 of the Royal Gardens, Kew. 



A plant sent from Hamburg, by Messrs. Booth, as this Fern, 

 proved to be the P. Caiharince of Langsdorff and Fischer. 



It does not appear to be in any of the Nurserymen's collections. 



The illustration is from the frond forwarded by Mr. Smith, 

 of Kew.
