Tenue, Clap/mm. (Fig. GO.) — This variety I believe was 

 raised from spores by Mr. A. Claj)ham, of Scarborough. A 

 delightful form; not so abundantly proliferous as Proliferum, 

 but being the connecting link between that form and Prolife- 

 rum-Wollastonii, much resembling, when well in character, the 

 latter form. It has a spreading lax habit, and although 

 circulated in bulbils by Mr. Clapham, and by Mr. C. Monkman, 

 it is by no means common in collections. Vivid green slender 

 fronds, about fourteen inches long, and three inches and a 

 quarter wide. Pinnae equal in length, except close to the 

 apex of the frond. Rachis and stipes exceedingly chaffy; scales 

 very pale, except near the base. Scales also on the rachidcs. 

 My thanks are due to Mr. C. Monkman, of Malton, for fronds. 



CmsTULATUM, Stansfield, MS. (Fig. 61. j — Gathered by Mr. 

 Stansfield, near Stainland, in Yorkshire, in the autumn of 

 1861. The fronds are from two to three feet in length, and 

 from nine to twelve inches in breadth. Generally terminating 

 in tufts or crests. The pinnrc are also occasionally crested.
