Laciniato-laceratum, Clapliam. (Fig. 429.) — Gathered near 

 Harrogate, in 1859, by Mr. A. Clapham, of Scarborough. A 

 large-growing narrow-fronded form. Length three feet, usual 

 width less than six inches. A singular and handsome lacerate 

 form of laciniatiim, densely soriferous. Pinnae and pinnules 

 very various, no tv/o alike, varying from one to five inches in 

 length, mostly furcate or fan-shaped at their apices. I am 

 indebted to Mr. Clapliam for fronds. 



CoLPODES, Moore. — Found by Mr. G. B. Wollaston. Length 

 eighteen inches, breadth five inches. Symmetrically lanceolate. 

 Pinnae distinct, broad, and acute, and some branched towards 

 the end. Pinnules distinct, ovate-oblong, profoundly-pinnatifid. 

 The distinct character is in the lobes curving towards the 

 apex of the pinnule, forming a very open sinus. Lobes 

 acutely toothed. 



Decurrens, Moore. — Found near Conistone, in the Lake 

 District, by Mr. G. B. Wollaston. Length from twelve to 

 eighteen inches. Lanceolate in form. Pinnee rather narrowed 

 towards the apex, which however ends abruptly and irregularly, 

 as if the tijD had been cut off. Pinnules distant, sessile, and 

 decurrent, linear-oblong, pinnatifid; teeth not conspicuous. The 

 frond seeming as if nibbled all over.
