56 Ferns of British India and Ceylon. 



lanceolate; pinnules about 15 pair, about 1 inch long by--f— § inch 

 broad (those of the lower side of the 1-2 lower pinnae sometimes 

 more developed), cut down |— | towards the midrib into obtuse 

 lobes which are sharply toothed, or sometimes, especially towards 

 the apex of the frond, entire or nearly entire except the sharp 

 serratures, sori small. Var. normalis, Clarke, F. N. I. p. 519. 

 Nephrodium lacerum, Baker, Syn. Fil. 273, since referred to 

 Filix-mas in the Ann. Bot. Dr. Watt has collected specimens in 

 Munipore, and Mr. Levinge in Sikkim (Badam Tham), quite 

 intermediate between this and cochleata. Baker's lacerum is from 

 Japan. 



Var. |3 parallelogramma. Clarke's var. khasiana is a 

 synonym here ; it only differs in the apex of the pinnules being 

 rather more sharply serrated, it is from Nongbri in Khasia. 

 The sub-variety of this called Clarkei is paleacea Don. 



Var. y elongata. North India botanists appear to have 

 adopted Wallich's name of marginata for this variety ; elongata. 

 Swartz, Syn. Fil. 117, is the older name, and was adopted 

 by Sir W. Hooker in his Sp. Fil. vol. iv., and by Hooker and 

 Grev. Ic. Fil. t. 234, Wallich's name being given as a synonym. 

 It has been collected on Maxwell's Hill, in Perak, 3,000 feet alt. 

 by Day. 



Var. § cochleata. Wallich's Arthobotrys avana is this 

 species, with the fertile segments so contracted as to be quite 

 bead-like ; it is from Ava. 



Var. e panda. This fine fern may be said to resemble 

 odontoloma [Moore), with the pinnae pinnatifid only, instead of 

 being pinnate ; it has apparently been collected only by Mr. 

 Clarke. There are specimens at Kew which are intermediate 

 between this variety and Schimperiana. 



Var. subtriangularis. Crown of the rhizome and base of 

 stipe furnished with long black linear-pointed scales ; stipes
