88 :,YGODIUM FOIISTERI. 



A warm greenhouse species. 



Native of the Polynesian Islands. 



In general habit it is similar to the Lycjodium, in which 

 family it was placed by Schkuhr. 



Fronds scandent, twining, and conjugate; usually three 

 (sometimes four) pairs of pinnae, with an ultimate double 

 pinna, (which is sometimes single.) Pinnte broadest at the 

 base, and narrowing to the apex; an inch and a half in 

 length, and thin in texture. Colour bright green. 



Sori consisting of indusiate cysts, making an interesting row 

 of spore-cases beyond the margin of the frond. 



For the fronds illustrated my thanks are due to Mr. J. 

 Smith, Curator of the Royal Gardens, Kew.
