The present fern, Asplenium Ceterach, and in fact all species 
that flourish on rocks and walls, require to be grown in exposed 
situations, using a large amount of stone with the soil. The plan 
adopted by myself is to grow them in pots, giving the protection of 
a cool greenhouse in winter, and in April plunging them amongst 
stones and sand in a long narrow shallow box, fastened on the 
north side of a wall five feet from the ground, and only watering in 
very dry weather. 
THE MAIDENHAIR SPLEENWORT. 
Asplenium Trichomanes. — Linnceus. 
A COMMON species throughout the United Kingdom, growing on 
rocks and walls, and occasionally in hedgerow banks. It attains a 
large size in the West of Ireland, sometimes the fronds being more 
than a foot long. Found at every height up to 2,000 feet above the 
sea. On Ben I.awers the plants are very small. In the Eastern 
Counties it is not common. A native of the Atlantic Isles, Cape
