ADDER'S TONGUE. 193 
Adder's Tongue : — ‘Templeton remarks that it is 
partial to moist, loamy or clayey soil, especially 
meadows liable to be flooded after heavy rains: he 
particularizes a locality of this nature on the banks 
of the river Logan, about three miles from Belfast.” 
Mr. Thompson, in company with Mr. Ball, found the 
Adder’s Tongue in the south of Arran, off Galway- 
The Adder's Tongue, in order to succeed well in a 
garden or pot, must be removed, like the Moonwort, 
_ with a large sod of the herbage amongst which it is 
found. If its connection with the herbage, of what- 
ever nature this may be, is once disturbed, it is 
extremely difficult to get the plant to grow: it may 
perhaps live out the usual duration of the frond, but 
will be almost sure to be found wanting when looked 
for in the ensuing spring. Most cultivators consider 
this genus, like Botrychium, perfectly unmanageable. 
But this need no longer be the case; and it will be a 
boon to Science if any one will attentively study both 
“genera under cultivation, keeping in mind the con- 
ditions indispensably essential to success. First, dig 
up the plants when perfectly mature, and with every 
particle of their roots intact ; secondly, leave the grass. 
“or accompanying herbage of whatever kind, undis- 
urbed ; thirdly, let the soil, whether hungry, as in the 
ase of Botrychium, or loamy, as in that of Ophio- — 
um, in which the plant is found growing, be the 
compost allowed near it; and, lastly, cultivate
