Tenuifolia, Clapham, (Fig. 437.) — Found in 1865 in 

 Mr. Barnes' Nursery, Thirsk, and now in the possession of 

 Mr. A. Clapham, of Ramsdale Bank, Scarborough. A very 

 elegant and distinct Fern, at present about eight inches in 

 length, and three inches in width in the widest part. Pinnas

 very sharp-pointed. A thin slender form, likely to become

 Mr. Clapham for fronds.
