have large cordate leaves, and are very effective when asso- 
ciated with some of the more brilliant-flowered shrubs. The 
former is rather tender, and should only be planted in sheltered 
situations. 
d. Shrubs requiring the proteetion of « wall or other shelter. 
—There are many beautiful and interesting shrubs, some of 
‘which are not included in either of the foregoing divisions, 
that may be successfully cultivated with a little additional 
care in winter. Many of them do not, it is true, require any 
covering, or even the protection afforded by a wall, in the 
milder parts of the kingdom, except during unusually severe 
weather. But as a rule they must be planted in warm well- 
drained soil, and, beyond the districts named, they will need 
the protection of a south wall, and in some cases extra covering 
in winter. Amongst the erect tender shrubs frequently met with 
we may enumerate: Euonymus Japonicus varieties, Photinia 
spp., Arbutus Andrachne, ete., Pittosporum spp., Myrtle, Ele- 
agnus Japonicus varieties, Escallonia spp., Bupleurum fruti- 
cosum, and Osmanthus—with more or less ornamental foliage ; 
and Hydrangea spp. and, varieties Magnolia grandiflora, Cornus 
(Benthamia) fragitera, Viburnum spp., Buddleya Lindleyana, 
and Spirea Lindleyana—with conspicuous flowers or fruits. 
Tender shrubs requiring support as well as protection are 
equally numerous. The following are some of the more 
familiar species: Lonicera spp., Bignonia spp., Jasminum 
revolutum, etc., Euchsia macrostema varieties, Berberidopsis 
corallina, Lapageria rosea, Philesia buxifolia, Stauntonia lati- 
folia, Lardizabala biternata, Akebia quinata, ete. The fore- 
going list might be extended almost indefinitely, especially 
if made applicable to the colder parts of the kingdom. Fur- 
ther remarks relative to the hardiness of plants will be found 
under the head of General Observations. Amongst dwarf, 
trailing, or creeping shrubs suitable for covering banks, rock- 
work, etc., we may mention the genera Vinca, Helianthemum, 
Cotoneaster, Polygala, Rosa, Erica, and Clematis. 
II. Hersacrous PLants. 
In nearly all parts of the temperate zone of the northern 
hemisphere there is a great preponderance of the herbaceous 
over the woody vegetation, and we have scarcely any hardy
