zigzag and prominent, the lower pinnae rarely twice pinnate, the indusium 
glandular, and the whole plant much more delicate. 
It should he observed that the above remarks are not intended to apply to that 
plant which Sir J. E. Smith’s herbarium contains, and which Sir W. J. Hooker 
describes as a variety of dilatatum, under the above name. The spinulosum of 
northern botanists, of Sir J. E. Smith, and of the Liverpool Botanic Garden, is, 
in realitv, but a variety of the next, and closely approaches to the recurvum of 
Bree, and dumetorum of Smith, if not identical with them. The plant here 
intended to he described is altogether different, and in cultivation retains precisely 
the character of the wild plant, never approaching in the most remote degree the 
Aspiclium dilatatum, though the mountain form of this latter plant has the lower 
pinnae much abbreviated. 
In a variety of spinulosum given me by Mr. J. Merrick, of Manchester, the 
lobes on the upper side of each pinna are much larger than those on the lower ; 
also, it may be remarked, that in dry situations the pinnules will become convex, 
but this is by no means common.
