15G rOLYSTICtlUM AXGULAllE. 



having a conspicuous auricle ; mostly only spinous at the tips 

 of the pinnules and auricles. Stipes, rachis, and rachides 

 scaly. My thanks are due to Messrs. Stansfield, of Todmorden, 

 for fronds. From Mr. Elworthy, of Nettlecorabe, I have received 

 a decomposite form of Laxum, in which the pinnules are 

 deeply incised, the superior basal pinnule much longer than 

 the others, and subtripinnate. I have also received fronds of 

 d Decompositum form of this variety, from the Rev. F. Mules, 

 of Mar wood.

Proliferum Padleyaxum, Loicc. (Fig.. 133.) — Found at 

 Monkleigh, North Devon, by the llev. Charles Padlcy. Normal 

 in outline. Length eighteen inches. Bipinnatc. Pinnce crowded, 

 opposite on the lower half of the frond, and alternate above, 

 linear-lanceolate, apex acuminate, crowded, in the basal half of 

 the pinn;ii linear, and strongly auriculatc, the rest much broader. 

 The distinctive feature of this Fern is the abundance of long 

 spines along the margins as well as at the apex of the pinnule. 

 I am indebted to the Rev. Charles Padley, for fronds. 



Setigerum, Moore. — A sub-form of Biserratum, found near 

 Barnstaple by the late Mr. C. Jackson. A large Fern, with 

 shorter pinnae, but equally large pinnules; the end of the 

 lobes terminating in a very long seta, hence its name. Too 

 near Biserratum to figure. 



Trtpinnatum, Moore. — This is of the same noi*mal form as 

 my Tripinnatum, (now changed to Achurodes,) but has not 

 that chaffy character, nor the ladder-like horizontal position of 

 the pinna). The pinnules are identical. It is unnecessary to 

 give an illustration. Mr. Elworthy has found this variety at 

 Nettlecombe. The pinnules slightly imbricate; the stipes, 

 long and very scaly, and the pinntc elongate^triangubir,
