Linnaeus first altered it from Phyllitis to Asplenium Scolo- 
pendrium and Withering adopted the same name. All 
others designate it now Scolopendrium vulgare. The com- 
mon name given to it in Prance is “ Langue de cerfe,” 
Hartstongue. 
Scolopendra, from whence Scolopendrium is derived, is 
the scientific name of a Millipede, or Thousand-legs, an 
insect with which most persons are very well acquainted. 
The Pern was given this name because some fancied that 
the covers and fructification of this plant resembled these 
insects. 
Here there is no difficulty as to cultivation. As generally 
the finest plants are found in moist, shady, hedge-banks, the 
same result may be expected, if due regard be paid to the 
course which nature points out. If placed in rich soil in a 
greenhouse, varieties will be produced, and the plant will 
depart from its ordinary form. 
Pamilt IV. Maidenworts. Adiantece. 
Covers linear, either parallel to the edge of the leaflets or 
apparently formed by their bent-back edges. This family 
contains the true Maidenhair, Adiantum capillus Veneris, 
which is not one of the Perns of the Axe. 
Genus 1. 
Hard Perns. Bleclina, The covers are parallel to the 
edge of the leaflets. The bags of spores lie in a long straight 
line between the mid-rib or mid-vein, and a vein somewhat 
parallel to the mid-vein. This vein is connected with the 
mid-vein by transverse lines. This genus is distinguished 
from the rest of the family in not having the edge of the 
leaflet bent back when fructification is formed. Thirty-one 
species of this genus have been discovered, though we have 
only one in Great Britain.
