80 ENGLISH BOTANY. 



by the veins being less impressed above, but chiefly by the indusium 

 being firm and very convex, and retaining its shape like that of 

 L. Filix-mas instead of being thin, flat, and soon crumpled up when 

 the spore-cases swell and raise its edges. Still there can be no 

 doubt that it is a form connecting L. spinulosa and L. Filix-mas.

Caudex short, very thick, separating into few divisions or crowns, 

 which are very thick and erect or " creeping." Fronds all similar, 

 many produced from the extremity of each division or crown, sub-ever- 

 green, "semi-erect" (Newman). Stipes long (two-thirds to as long 

 as the lamina), stout, deeply channelled on the anterior face, con- 

 taining 5 vascular bundles, thickly sprinkled with minute clavate or 

 stalked glands and rather thickly clothed with broadly-ovate cuspidate 

 and lanceolate tapering entire pale brown nearly concolorous sub- 

 persistent scales. Lamina firm, dull green, sprinkled beneath with 

 very numerous clavate glands, narrowly oblong or lanceolate-oblong, 

 tapering more or less gradually towards the apex, abrupt at the base, 

 bipinnate or almost tripinnate ; lowest pair of pinnse unequally 

 triangular with the 2 basal pinnules on the lower side of the secondary 

 rachis much longer than those on the upper side, nearly as long as 

 the succeeding pair of pinnae ; the others becoming gradually longer 

 and narrower as far as a little below the middle of the lamina, after 

 which they at first gradually and then rapidly decrease in length; 

 all of them shortly stalked, pinnate ; pinnules " flat or convex," lan- 

 ceolate-oblong ; those towards the base of the lamina shortly stalked 

 and pinnatipartite, or sometimes almost pinnate; those towards the 

 apex of the frond decurrent at the base ; ultimate segments adnate by 

 a broad base and decurrent on the lower side, oblong inciso-serrate, 

 with the teeth hooked upwards and strongly mucronate. Ultimate 

 veins rather faintly impressed on the upper surface, running to the
