POLTSTICHUM ANGT7LABE. 141 



Thompson ij:, Lowe. (Fig. 119.) — Found at Sir "William 

 Hairis's, Lynniouth, Devonshire, by Mrs. Thompson, of Exeter, 

 and named in honour of that lady. This crested variety is narrow, 

 with a large spreading tassel at the apex. Length of frond 

 from twelve to fourteen inches, width scarcely three inches in 

 the widest part. Pinnje, the three basal pairs sub-opposite, the 

 next three pairs alteraate, and the remainder opposite. Some- 

 times all alternate. Bipinnate; four or five pairs of pinnules, 

 large, and an ultimate expanded one, which is crested. The 

 superior basal pinnule much the largest, especially in the centre 

 of the frond; it is placed parallel with the rachis, and perpen- 

 dicular to the secondary rachis, on which it is situated. Stipes 

 and rachis scaly, pinnules spiny, and having a Polystichum 

 aculeatum look. A^'idth of frond equal except near the apex, 

 where it is sometimes, but not always, slightly contracted, 

 beyond which expanded out into a branched Corymbose head 

 of three inches and a half in width. A verv distinct form, 

 approaching Corymhiferum of Moore. My thanks are due to 

 the Rev. Charles Padley, of Bui well Hall, for fronds. 



PoLUEiDES, Lowe. (Fig. 120.) — Found near Exeter, by the 

 Rev. Charles Padley, of Bulwell Hall, Xottinghamshiie. This 

 is a handsome large-growing Fern, which sometimes bends round 

 in a remarkable manner. The length of the frond is about 

 thirty-eight inches. About eight inches from the apex it becomes 

 branched, and one of the branches again branched, the latter 

 being much shorter than the others. This may be con- 

 sidered as one of the forms of the variety JMulliJidum, but 

 having characters sufiiciently distinct to warrant its being named. 

 The stem is very scaly quite to the apex of the frond. The 

 pinnaj are everywhere alternate from the base to the apex, and 

 they are shorter on one side of the rachis than on the other, 

 as the following measurements will shew: — Taking a frond of 

 thirty-eight inches in length, at about the height of nine inches 

 the pinnjE on the left side are from three inches and a quarter 

 to four inches in length, whilst on the right side none exceed 

 one inch and a half. At eighteen inches in height the pinnse 

 become more equal in length, but are yet shorter on the right 

 side. The pinnae are remote, long, narrow, and acuminate at
