ASPLENIUM MARINUM. 
MARINE, OR SEA SPLEENWORT. 
All writers seem to have agreed to call tliis plant 
by the same name, so we are not troubled with 
synonyms, as is the case with most others. The 
root is tufted, black, with stout fibres. Rachis, or 
stalk, black or brownish black, smooth, and shining, 
often bent at the base, free from pinnae at the lower 
part, the first set opposite, the upper mostly alter- 
nate, slightly decurrent; upper side of each pinna 
auricled, or possessed of a projecting lobe ; mid-vein 
commencing at the lower corner, and consequently 
not running through the middle. Pinnae are firm 
in texture, toothed, and glossy green. The specimen 
from which the illustration was impressed, has the 
pinnae rather longer and narrower than the normal 
shape. The sketch of the Venation in the plate 
shews that the oblong sori are produced from the 
anterior veinlet, as in the Asplenium Trichomanes . 
They range in two rows, one on each side of the 
mid-vein, and are set diagonally to it. The in- 
dusium, or scaly cover, opens along the anterior 
margin, or on that side nearest the point of the 
pinna, and furthest from the stalk. The plant is 
evergreen. 
Uses.— T he thick consistence of the leaves will 
yield a mucilage, which was once thought to be a 
useful application to burns. 
Where found.— It grows in the yellow perpen- 
dicular rocks of the Dunscombe Cliffs. I see no 
reason why it should not grow in the yellow rocks 
at the upper part of Salcombe Hill, but it has not 
been detected there. In going to the Dunscombe 
Cliffs, surmount Salcombe Hill by the road; pass 
through the village of Salcombe, and proceed half- 
a-mile further to Dunscombe Farm. Go through 
the yard and straight out to the cliffs. A carriage 
can be taken this way. The farmer, however, dis- 
courages visitors through his premises. Or, there 
is another way— if on foot Suppose yourself again
