Duration. The caudex is perennial. ‘The fronds are annual, produced in spring and perishing in 
autumn. 
This species may be known from those to which it is allied by several characteristics. ‘The fronds 
‚enerally broadest at the base, always covered with minute glands, which give 
asant balsamic fragrance, often appreciable in the vicinity 
of the living plants during sunshine 
‘The outline of the pinnules—bluntly oblong—different from that which occurs in any other native 
species, is most nearly approached by 
me states of the Incised Маје Рог, and the serratures, as in 
that species, are not at all spinulose or awn-tipped, but are short and merely acute ; but from that it is 
distin 
guished by its size, its outline, its glandular surface, and its glandular-fr 
d indusium. It can 
hardly be mistaken for any other of the Lastreas, nearly all the rest of which have spinulose serratures. 
‘The culture of this Forn is very similar to tha 
of the other larger growing kinds, It grows well in 
free well-drained loamy soil; and the faet of its range bein 
almost if not quite confined to limestone 
is that the use of limestone among the soil m

It is of far more importance that the soil should be kept moderately moist, and 
be of such a texture, as may 
tho same time prevent any accumulation of stagnant water. Tt 
is increased by separating the lateral crowns formed by the caudex. "The latter is the better for being.

Mr. Wollaston notices a variation in which the fronds or the pinne aro simply or multifdly divided 
at the apes, but it is not a c 7
