NEPHRODIUM. 
149 
This fern used to be called fcenisecii, or Hay-scented 
Buckler-fern, but Sir William Hooker prefers the term 
c emulum . 
Ireland and the West of England are its favourite 
habitats. 
In the fernery it requires a great deal of shade and 
moisture. It can exist with less consideration, but if 
neglected it will gradually assume the stunted form. 
21. Nephrodium sphmlosum. Prickly Buckler- 
fern. Yar. dimetoram. 
Caudex short, stout, scaly. Stems tufted, scaly. Eronds 
ovate, 1 to 2 feet high. Pinnae close and blunter. Leaflets 
broad. 
This is a fern of smaller size ; the fronds bipinnate 
and very glandular on the rachis, stipes, and lower sur- 
face of veins ; the pinnae are blunt and concave, arranged 
closely together ; the leaflets crowded, convex, crisp, 
having broad coarse teeth tipped by a sharp bristle. 
Altogether it is a more compact and less elegant va- 
riety ; its stem is very pretty, pale green in colour, and 
with dark brown scales. 
It is found in the mountain districts of Wales, West- 
moreland, Derbyshire, and the Lothians. 
In the fernery it requires the same treatment as the 
Mountain -fern.

Fronds 3 to 4 feet in height, oblong-lanceolate, glossy, without 
glands, bipinnate. Lower pinnse distant, stalked ; upper ones
