This species inhabits chiefly the central part of Europe. Besides 
the British stations, it is found in France: e. g. Arles, Jura; in 
Belgium ; in Spain, on the Pyrenees ; in Italy: e. g. Naples; among 
the mountains of Switzerland; in Germany, and Hungary; and in 
Greece. It also occurs in the Scandinavian kingdoms, according to 
Sadler; though Ledebour and Ruprecht appear to be doubtful of its 
occurrence in European Russia. In Asia, the species is recorded as a 
native of the Ural mountains, in Siberia ; and it is found in Kashmir. 
Asplenium fontanum is a frame or greenhouse Fern, particularly 
desirable in a limited collection on account of its small size and 
evergreen habit. The plant is easily grown, if carefully tended, but 
being of small size, it of course requires but a moderate share of 
pot-room, and like most of the small Ferns, Aspleniee especially, 
the pots must be thoroughly drained. Small plants like this, too, 
require considerable care in watering, the condition to be aimed at ` 
being to keep the soil and the roots in a moderately moistened state, 
with as little fluctuation as possible. Hence, while the liberal sup- 
plies which would be required by larger and more rapidly growing 
kinds, would reduce this to an unhealthy condition, if it did not 
kill it, the small bulk of soil renders any neglect in the opposite 
direction, if it occurs in hot parching weather, liable to become 
fatal. When this amount of eare is bestowed, the plant may be 
grown without risk of failure. It should be potted in porous soil,
