POLYSTICHUM ANGCLARE. 179 



AcuLEATOiDES-CBiSTATUM, Wolliiston. f Polystichum aculea- 

 tum-cristatum. J — From the collection of the late Mr. Charles 

 Jackson, of Barnstaple, and now in the possession of the Rev. 

 Charles Padley, of Bulwell HaU. Mr. G. B. Wollaston informs 

 me that this plant has been known for some years, and was found 

 in Devonshire, by Mr. Dempster, and taken to Mr. Jackson. 

 Mr. Moore supposed at the time that it was a variety of Poly- 

 stichum actdeatum, which he named Cristatum. It is however, 

 no doubt, a variety of Polystichum angular e, therefore Mr. 

 Wollaston has re-named it. A long narrow^-fronded form, about 

 eighteen inches in length, with opposite or sub-opposite pinnae, 

 lanceolate or linear-lanceolate in form, the apex indistinctly 

 cristate. Pinnules entire, small, a lengthened oval, aculeate, 

 scarcely auricled, a strong spine takuig the place of the auricle. 

 Stipes and rachis sparingly covered with hair-like scales. I am 

 indebted to the E,ev. C. Padley, of Bulwell Hall, for fronds. 

 The variety differs from Aculeatoides in having longer and 

 narrower pinnae, in being somewhat cristate, the pinnules being 

 wider apart, and more aculeate. 



Decompositum-multifidum, Lowe. — A multifid form of 

 Decompositum, found in Devonshire by the Rev. F. Mules, of 

 Marwood. Fronds large, three feet six inches in length, 

 lanceolate in form, and eight inches wide. Three or four 

 inches below the apex branching into three branches, these 

 again branching; their apices furcate, the furcations being 

 cristate. Stipes thick, twelve to fourteen inches in length; 

 scaly. Rachis scaly; rachides scaly. The three pairs of basal 

 pinnae remote, the rest approximate, the basal pair shorter 

 than the others; all approximate. The inferior pinnules 

 somewhat larger than the rest, stalked almost to the apices of 

 the pinnae, long, blunt-pointed, deeply lobed, and strongly 

 auriculate. In the centre of the frond pinnules more deeply 

 cut, the basal lobes divided to the costa, and the superior 

 basal pinnules larger than the others, densely but minutely 

 spinous. My thanks are due to the Rev. F. Mules for fronds. 



Semitripinnatum, Moore. — A not uncommon large-growing 

 variety, two feet or more in length, and six or seven inches 

 broad. Almost tripinnate. Pinna? opposite below, alternate
