Arcuosum, Clapham. (Fig. 443.) — Gathered near Ilkley, in 

 July, 1863, by Mr. A. Ckpham, of Scarborough. A form of 

 dissectum, in which the fronds and pinnae are arcuated. This 

 bended character gives the frond a singuhir appearance. 

 Length two feet, width eight inches.

Rachiuioides, Clapham. (Fig. 444.) — Gathered near Scar- 

 borough, in October, 1864, by Mr. A. CLapham, of Scarborough. 

 A distinct narrow-fr ended form. Stipes and rachis covered 

 with long scales. Length of frond twenty inches, of which 

 the lower six inches is naked; width four inches at the widest 

 part of the frond, that is, above the centre. Pinna? alternate, 

 small at the base, irregular in distribution, often a third of 

 them absent, horizontal at the base, and ascending above, their 

 apices acuminate and very sharp-pointed. I am indebted to 

 Mr. Clapham, of Scarborough, for this variety.
