- The fronds of this species are eighteen inches long, 
broadly lanceolate, of a deep green colour, smooth as 
well as the stipites ; the pine are lanceolate and pinnu- 
lated, and these pinnules again pinnatifid. The groups 
of cap are di as in Aspidium filiz mas, but

' There are none of the species of Darea hitherto found 
in Europe; most of them being native either of the 
Cape of Good Hope, Bourbon Island, or New Holland. 
This genus was first established by Bergius under the 
name of Ceenopleris. The lines of capsules are generally 
situated in the marginal sinuses of the narrow lobes of 
the frond. The generic character is represented b 
Sprengel, in his third Plate, exhibiting part of the frond 
ot D. odontites. Sometimes, however, the groups are at a 
ter distance from the margin. | The D. fumaroides, 
ately discovered in Caraccas by Humboldt and Bon- 
pland, to whom all the physical sciences owe so much, 
is a most beautiful species. The stipes is smooth, chan- 
nelled, and half a foot long ; the frond from three to 
five inches; bipinnate, the pinne and pinnule alter- 
nate ; the pnoule are linear, obtuse, and bipartite, 
with bipartite lacini. 
The D. rhizophylla is figured by Sir J. Edward Smith, 
eris rhe ila (icon. in edit. tab. 50.) is a 
native of the West Indies. The D. vivipara, which is 
figured by ius, (Act. Petrop.6. tab. 713.) affords an 
instance of buds being produced from the pinnule of 
the frond. This fern is found in the woods of Mauri- 
tius and Bourbon Islands, 
(2.) Asplenium (Willd. Sp. Pl. 1967.) 
Capsules in linear separate groups, originating late- 
3 from a vein, and opening towards the rib. 
Yilldenow describes about one hundred of this ge- 
nus, of which only eight are natives of Britain. 
1. A. trichomanes. The stem of this Sairan species 
is very short, enveloped with the decayed stipites of 
former and having in the centre of these the 
buds of the future season. The pinne of the frond are 
oval, finely crenate, with a stipes of a shining purple 
hue, carinated in the under side. It is y found 
on the northern walls of our ancient buildings, where, 
although it requires but little moisture, it is in some 
measure protected from the total want of it. It is cor- 
rectly _— by Sowerby in Eng. Bot. 576, and by 
Woodville, Med. Bot. tab. 204. A syrup was formerly 
from a decoction of it, the whole plant pos- 
sessing a slight astringency ; but other ferns far exceed 
it in the ion of sweet mucilagi matter, 
abounding not in the frond, as Woodville observes, 
(Medical Botany, ut supra), but in their stems. Mr 
Teasdale found a variety of this fern with the frond 
a A. viride osm the a but differs, 
ing a green quadrangular stipes ; the pinne of 
finned sented, cadet t paler ; the middle fasci- 
culus of the frond is occasionally bifid. 
3. A, marinum. .This species has also alternate 
pinne, ovate, blunt as in A. trichomanes, and of a deep 
green colour, wedge-shaped at the base, and above 
sometimes united. On several parts of our coast, and 
in the sandstone caves at Wemyss in Fifeshire, observed 
by Sir Robert Sibbald. These three beautiful species 
sess an evident affinity with each other.

ternate, erect, veer pinne, eroded at the point.
