11. Nephrodium moulmeinense. The rhizome is creeping, 

 specimens lately received in very young state show ciliated 

 involucres on almost all the sori. Mr. Mann sends very fine 

 specimens from the Nambur Forest in Assam, with the pinnae 

 2 J inches broad. — Wall. Cat. 300. Polypodinm lincatum is a 

 mixture of this species and the next (costatum). 



12. Nephrodium costatum. The rhizome is sometimes 

 creeping, sometimes erect ; gathered by Mr. Clarke in the Jawi 

 Valley, Cashmir, 4,000 feet alt. 



13. Nephrodium Arbuscula. — The fronds sometimes attain 

 3 feet in length. 



Nephrodium larutense. (n. sp.) Stipe 8-12 inches long 

 furnished with very regular auricles below the pinnae, densely 

 villous with short hairs, as is the rachis ; fronds 2-3 feet long, 

 pinnae 10-12 inches long by i-J inch broad, finely acuminate at the 

 apex, broadly truncate at base, only cut down about J towards the 

 costa into short subfalcate lobes, texture herbaceous, colour very 

 deep green ; above, the costa midrib veins and lamina hairy ; 

 below, costa midrib and veins hairy, the lamina furnished with 

 minute resinous dots ; veins about 10 pair, much ascending, the 

 5-6 lower pair anastomosing ; sori medial, indusium elongated, 

 didymochlaenoid hairy.

 Incorrectly referred by me to saggittaefolium in my catalogue of 

 Mr. Day's plants. This will be placed in Mesochlaena by those

14. Nephrodium pennigerum. {Hook, in part.) 



The typical plant, which occurs in N. India, S. India 

 and Ceylon, has no reduction of the lower pinnae and no 

 auricles, 5-8 pair of veins anastomose, except in contracted 

 fertile pinnae, and the rhizome is often, if not always, more or less 

 creeping. In the description in the Handbook, instead of
