greatest degree of luxuriance. It appears to be also com- 
mon on the Continent of Europe and in North America. 
This species is of free growth, and easy culture, suitable 
either for rock work, shady borders, or wilderness scenery. 
It is one of the most compound and elegant of our native 
species, and though it may be grown fully exposed, yet it 
succeeds better in the shade.

The Hay-scented Buckler Fern has a large tufted cau- 
dex, with a broad crown and numerous roots. The fronds, 
which are terminal and adherent to this caudex, are per- 
sistent, the old ones remaining fresh until after the young 
ones are produced in the following year, which occurs 
about May; they are at tirst regularly convolute, and 
in the partially developed condition the larger size of the 
lower pair of pinnae is remarkably manifest. They vary 
from one to two feet seldom if ever more, in height, are 
of a pale-green colour, and have when fully developed a 
graceful drooping habit, and a remarkably crisped appear- 
ance, caused by each of the lobes of the pinnules being 
concave, its edges and spiny teeth being curled upwards. 
They are covered with minute nearly globular sessile 
glands, and have, when dried, a fragrance like that of new 
hay. The stipes varies from a third to one half of the 
entire height, and is dark coloured ajnd rigid, and clothed 
with long narrow laciniated pale-brown concolorous scales
