4 POLYPODIUM TRICHODES. 



sunshine very speedily blanches its large but delicate fronds. 

 Easily cultivated, yet requiring abundance of pot-room. 



An evergreen stove Fern. 



Native of the East Indies. 



Polypodium tricliodes came up spontaneously at the Royal 

 Gardens, Kew, in the year 1849. 



Fragile fronds bi-tripinnate, with linear-lanceolate pinnae, and 

 pinnatifid pinnules, with bluntly-lobed rather ovate segments. 



Length of frond usually from three to five feet; my plant 

 has fronds five feet and a half in length, which are naked 

 for two feet. 



Stipes and rachis covered with a silvery green fine powder, 

 hairy, with reddish brown scales, which are thickly scattered 

 near the base, becoming thinner upwards. 



Fronds terminal, being adherent to a stout somewhat creeping 

 rhizoma. Stipes scaly, and very much so near the base. 



Sori round, medial; brownish in colour. 



The pinnules, when young, are broad and flat, yet when 

 more mature contract by curling downwards. The midrib of 

 the branches fluted. 



To the ordinary observer the P. trichodes is not much unlike 

 a giant Asplenium filix-fcemiiia in general appearance. 



This species must not be confounded with Lastrea tdiginosa 

 of Newman, which is said to be a variety of L. cristata. 



For plants I am indebted to Mr. Moore, Curator of the 

 Chelsea Botanic Gardens; and to M. Schott, the Director of 

 the Royal Botanic Gardens of Schonbriinn, near Vienna; and 

 for fronds to Mr. Henderson, of Wentworth; and to Mr. Smith 

 and Dr. Hooker, of the Royal Gardens, Kew. 



It is in the Catalogues of Messrs. Veitch, of Chelsea; RoUisson, 

 of Tooting; Stansfield, of Todmorden; Sim, of Foot's Cray; 

 and A. Henderson, of Pine-apple Place. 



The illustration is from a young frond, from a plant in my 

 own collection.
