N. F.-m. acrocladon — ac-roc'-lad-on (having branched ends), Lowe. 



A beautiful variety, raised from spores by Mr. Clapham, of Scarborough. 

 It is a distinct, handsome Fern, having, in general outline, a strong resem- 

 blance to Aspidium (Foh/stichum) angulare. Its fronds, about 2ft. long, are 

 elegant in form and of a deep green colour ; the deeply-cut leaflets have their 

 extremities dilated into fan-shaped " fingers," these much-cleft tassels being- 

 largest on the basal leaflets, and becoming smaller towards the summit of the 

 frond, which terminates somewhat abruptly. — Lowe, Our Native Ferns, i., 

 t. 28 ; New and Rare Ferns, p. 127. Nicholson, Dictionary of Gardening, 

 ii., p. 440. 



N. F.-m. Barnesii — Bar-ne^-si-i (Barnes's), Moore. 



This particularly distinct and narrow-fronded variety was originally found 

 near Milnthorpe, in Lancashire. Its fronds, l^ft. long, are of about equal 

 breadth throughout, their leaflets being short, distant, somewhat triangular, 

 seldom more than l\m. long, and divided into oblong pinnules (leafits) 

 conspicuously toothed on the margins. The stalks and midribs are densely 

 scaly. This variety reproduces itself freely from spores. — Lowe, Our Native 

 Ferns, i., fig. 222. 



N. F.-m. Bollandiae — Bol-lan'-cli-as (Mrs. Bolland's), Moore. 



A strong-growing variety, which, on account of the great breadth of its 

 fronds, their winged rachises (stalks of the leafy portion),' and large, wavy 

 pinnules (leafits), is very distinct. It was originally found in a hedgerow at 

 Ashurst Park, Tunbridge Wells. The fronds, fully IJft. long, are broadly 

 spear-shaped and twice divided to the base of the leaflets, the divisions of 

 which are connected by the wings of the rachises. — Ljowe, Our Native Ferns, 

 i., fig. 188. Nicholson, Dictionary of Gardening, ii., ]3. 440. 



N. F.-m. crispum — cris'-pum (curled), Sim. 



This distinct variety, of small dimensions and compact habit, was originally 

 found in Westmoreland, Cumberland, and Yorkshire. It is a densely-leafy 

 Fern, with almost erect, short- stalked, dwarf, crispy, compressed, spear-shaped 

 fronds, 8in. to 12in. long, 4in. to Gin. broad, and of a peculiar dark green 

 colour. The pinnas (leaflets) and their pinnules (leafits) overlap each other,
