104 ASPLENIUM, § EUASI'LENIUM. 



and it certainly is a vrry liaiidsonie one. It approaches nearest to the normal 

 form of J. liiieafum, S\v., having the same general colour of frond and the same 

 copious fiarallol lines of fructification : hut the much larger size of the frond, the 

 very elongated and singularly acuminated pinna:, with the very deep and regular 

 senatures, will readily distinguish it. 



47. A. (Euasplenium) lineatum, S\v. ; (normal form) caudcx 

 thick erect or decumljent knotted paleaceous above with 

 brown lanceolato-acuminate scales, smaller and deciduous 

 ones more or less invest the stipes and rachis, stipitcs tufted 

 mostly terminal on the caudex 6 inches to a foot long lurid- 

 green or purplish, fronds 1-2 feet long lanceolate acuminate 

 impari-pinnate coriaceo-membranaceous dark-green paler be- 

 neath, pinnfc patent or horizontal petiolate from a broad ob- 

 liquely cuneate base gradually tapering into a long acumi- 

 nated more or less deeply and coarsely serrated apex, superior 

 base often truncated, veins apj)roximate forked patent, sori 

 linear copious in parallel lines from the rachis to the margin 

 (or nearly so) and generally occupying all the broader portion 

 of the pinna, involucres narrow brown membranaceous. — Sw.

 was the accurate Kunze who, in 1833, announced the fact that he had seen a 

 specimen of Asplenium nodulosum, Klfs. (A. lineatum, Sw. et nobis) with the 

 lower pinnae altogether, and the superior at the base, " dissected," and passing
