SCOLOPENDRIUM VULGARE. Common Hart’s-tongue. 
(Plate XX. Fig. 80.) This Fern is easily known, as it has 
its frond undivided. It is narrow, and sometimes found two 
feet long, very ornamental in hedges and on banks, and 
from its peculiar form attracting notice. It makes its first 
appearance in April, and is erect, except the apex, which 
remajns rolled up for some time, but at last becomes pendu- 
lous; it arrives at maturity early in October, and remains 
green till the young ones again make their appearance. The 
seed-cases are long, narrow, and placed across the leaf in 
lines pointing to the mid-rib.
