adapted for covering a wall ora trellis, and if care be 
taken not to prune away too many of the young shoots, it 
will afford its blossoms abundantly. It may also, by cut- 
ting in, be trained up as a small standard shrub, or it may 
be trimmed to a single stem and head, potted, and placed 
in the green-house. As extremely low evergreens, we may 
mention Gualtheria procumbens and Shallon, Polygala 
“Chameebuxus, and Astragalus Tragacantha; but these 
would probably be better placed among what are popularly 
called American plants, Of the more tender evergreens, 
we should name the Andrachne (Arbutus Andrachne), a 
beautiful shrub, but liable to be injured by severe frosts; 
and the pittosporum Tobira of Japan, with glossy foliage 
and fragrant flowers. The Broad-leaved Myrtle (Myrtus 
Romana), in warm places, and with the aid of a covering 
in the depth of winter, may be made to clothe the wall 
with its brilliant verdure for eight months in the year, and 
with its white flowers for some weeks in the end of summer. 
Treated in the same way, the noble Magnolia grandiflora 
(particularly the Exmouth variety) will yield its large and 
fragrant blossoms. Ancuba Japonica and Buxus Balearica 
are handsome shrubs, of a somewhat stronger constitution; 
the former is very ornamental in dull shady places, where 
no other shrub will grow, and it withstands severe frost, 
which destroys laurustinus. The beautiful tribes of Cistug 
and Helianthemum, some of which are quite hardy, are well 
adapted for adorning sloping banks. 
Amongst the shrubs that require a peaty soil, or at least 
a damp and shady situation, the splendid genus Rhodo- 
dendron holds the principal place. Of the larger species 
may be mentioned R. Ponticum, Catawbiense, and Maxim- 
um, with their numerous hybrid varieties. In early spring, 
R. Dauricum and atrovirens expand their blossoms among
