THE FERN WORLD 
Madeira ; and in the Azores, Canary, and Cape de Yerd 
Islands. It is found in the island of St. Helena, New 
Zealand, and in Western Australia. In Britain it is stated 
to have been found in Cornwall, but no other habitat has 
been recorded — a circumstance, however, which may arise 
from the fact of the plant being so diminutive, occurring 
amongst grass, starting up into life in the frigid month of 
January, and disappearing from sight early in the year. It 
was first discovered to be a British species in the year 1854, 
the place of its discovery being Petit But Bay, Guernsey. 
That island is now in fact, the only British habitat which is 
actually known to exist. 
Culture. — Precisely the same conditions of culture should 
be applied to this little plant as we have suggested for the 
common Adders -tongue.
