Ferns of British India and Ceylon. 85 



it is not represented at Kew, or probably in any herbarium in 

 England. 



6. Dictvopteris heterosora. Omit this species, it being 

 Aspidium vastum. 



4. Dictyopteris difformis. Perak, sea level. {Day. King.) 



1. Polypodium parasiticu-M. The rhizome is generally 

 creeping, though sometimes erect ; the fronds are sometimes 

 quite glabrous, at least in age. 



4. Polypodium Wallii. Dr. Trimen has named this in his

 very like the small parasiticum, must be very distinct, as it has 

 pinnate veins with 3-4 branches. Thwaites' MS. name on the 

 specimens at Kew is parasiticum var. latiusculum. It may be a 

 variety of No. 1, but as it is so very much larger and more 

 coriaceous, and as there are no intermediates, as far as I know, I 

 think it may be considered distinct.

 (Also in China.) 



:.\. Polypodium universe. {Baker.) Densely tufted ; fronds 

 simple sessile, rigidly coriaceous, linear, 1I-2 inches long, ^-\ 

 inch broad above the middle, narrowed gradually to the base, 

 furnished with deciduous brown hairs, midrib distinct ; veins 

 immersed, hidden ; sori oblong crowded, uniseriate, confined to 

 the upper part of the frond, where they fill up the whole of the
