AN ENUMEEATION OP CULTIVATED FEENS. 287 



OBS. On receiving this plant, it accorded so well with the 

 Indian specimen of P. obliquum, which led to that name being 

 inserted at p. 149, but the plant grew out of its imported form ; 

 and if the Indian plant (which has not yet been introduced) 

 should assume the character of this by cultivation, then this 

 name must become a synonym. 



The introduction of this species is due to Mr. Eichard Oldham, 

 the last special collector of plants sent out from Kew, who, 

 after remaining three years in Japan, visited Formosa, where 

 his health failed. He returned to Amoy, and there died in 

 November, 1864.
