Ferns of British India and Ceylon. 279 



Var. 7 aureum. {Clarke, F. N. I. p. 533.) Differs by having 

 the minute pubescence bright and golden, the fertile fronds longer 

 than the barren, and the pinnae sometimes contracted near the base ; 

 the frond truncate at the base, i.e., the lower pinna not reduced. It 

 is to be feared that none of these characters are permanent. It is a 

 form from Sikkim and Bhotan, 1,000-4,000 feet elevation, and 

 from Assam. 



Aspidium multijugum. (Wall. Cat 348.) Taken by Mr. 

 Clarke in his type of var. miiltijuga, is typical extenstim (Bl.) 



Var. didymosorum. (Parish, Bedd. F. B. I. t. 200.) From 

 Tenasserim ; is a very hairy form of molle, lower pinnae not at all 

 reduced, sori twin, confined to the two lower vc inlets (the latter 

 character probably not constant.) Wall. Cat. 354, Asp. canescens, 

 from Singapore, second sheet, is this plant. 



Asp. tectum ( Wallich, Cat. 394, in Linnaean Herb.) is a deltoid 

 form of molle with no reduction of the lower pinnae, and a creeping 

 root. 



16. Nephrodium crinipes. (Hook.) Stipe up to i\ foot long, 

 stout, erect, clothed, as is the main rachis, with lanceolate-linear 

 brown scales ; fronds about 2-3 feet long, pinnate, dwarfed below 

 into auricles ; pinnae horizontal, 4-6| inches long, f-f- inch broad, 

 cut down \— f towards the midrib into oblong scarcely acute lobes, 

 the upper basal one often somewhat enlarged ; texture herbaceous ; 

 veins beneath minutely puberulous ; costa, costules and veins spar- 

 ingly furnished with longish hairs above ; veins 6-8 on a side, the 

 two lowest pair anastomosing; sori medial, but a little nearer the apex 

 than the costule ; indusium reniform glabrous persistent. Hook. 

 Syn. Fil. 294. Bedd. F. B. I. t. 263. 



North-east Bengal, up to 1,500 feet elevation, from Nepal to 

 Assam and Chittagong ; Malacca (Mr. Clarke's Nilgiri example is 

 a portion of a contracted fertile frond of pennigerum.) 



17. Nephrodium ferox, (Moore?) Stipe 1 2 feet long
