Ferns of British- India and Ceylon. yy 



is about i foot ; pinnae sessile or shortly stalked, generally distant, 

 7-12 on each side, the 2-3 lower ones generally very distant, 

 suddenly reduced and small, or auricle-like, the upper ones 5-7 

 inches long by i-2f inches broad, texture papyraceous, the 

 margins shortly lobed, the lobes about f- of the distance to the 

 costa, rounded but sometimes, apiculate, perfectly glabrous on 

 both sides, except the costa above ; veins 8-1 1 on each side, the 

 3-6 lower pair anastomosing, either joining the opposite vein or 

 alternate with it, and joining the spurious costule ; sori medial, 

 or rather below the middle of the veins. Nephrodium penni- 

 geruni var. multilineatum, Clarke, F.N.I. 532 (Nos. 43,103, 

 19,678, 19,884, 19,898.) N. amboinense var. evolutum, Clarke, 

 Jour. Linn. Soc. Bot. xxiv. 417 (Nos. 44,509, 44,528, 44,534), 

 N. amboinense, Clarke, Jour. Linn. Soc. xxv. 95 (No. 40,852). 



Shillong, 3,500 feet alt. and Tura, Garo Hills, 4,000 feet alt. ; 

 Nambre Forest, Assam ; Neechoogard, Naga Hills, 500 feet alt. 

 (Clarke). Below Shillong, 4,500 feet, Khasia (Mann), Burkul, 

 Chittagong (Clarke). 



In both this and molle var. major, the veins of the 

 lowest pinnules (i.e. the ones nearest the main rachis) are occa- 

 sionally forked and anatomose towards the margins ; this, how- 

 ever,. occurs in several other species. This is a well-marked fern, 

 distinguished by its very papyraceous texture and its broad 

 distant pinnae. The Java specimen in the amboinense bundle at 

 Kew, with which Mr. Clarke compares it (Jour. Linn. Soc. xxv. 

 95), is only the apex of a frond, very distinct from this, probably 

 Arbuscula ; with critical Nephrodiums it is absolutely necessary 

 for determination to have the whole frond and stipe, also the 

 rhizome if possible. 



Evolutum var. ft. Rhizome creeping, pinnae narrower than 

 in the type and more rigid in texture. Nephrodium procurrens 

 var. microlobum (Clarke, Linti. Soc. Jour. xxiv. p. 416). 



KopiliHot Springs, N. Cachar Hills, 1,000 feet alt. (G. Mann), 

 Nambe Forest, Assam (Clarke, No. 40,811) ; perhaps a distinct 

 species. I have only seen two specimens.
