Evergreen Trees. 601 
Variegation in large evergreen trees—if we except the silvery 
bands on the leaves of many Conifers, which may be termed 
natural variegation—is almost unknown. There is, however, a 
variety of Cryptomeria Japonica beau.ifully variegated with 
yellow, a silvery variety of the Spruce Fir, and gold and silver 
varieties of Cupressus Lawsoniana ; and perhaps the most beauti- 
ful are the gold and silver variegated Yews ; but the latter are 
better referred to the shrubby class. Variegated Hollies 20 
to 30 feet or more high are occasionally seen, but as a rule 
they do not exceed the dimensions of a shrub. 
- Weeping forms in the true sense of the word, as applied to 
the Weeping Ash, Elm, Beech, etc., are scarcely represented. 
Some, like a variety of the Silver Fir, have depressed branches. 
The varieties of Biota, Taxus, etc., with pendulous branches 
are more properly referred to the frutescent class. 
b. Deciduous Trees.—In this class we have greater variety 
than in the preceding, both in habit and foliage, as well as 
flowers. We have trees of large and small dimensions, desirable 
in landscape gardening either for the beauty of their flowers 
or foliage, or for both combined. The number of large trees 
distinguished more for their foliage and grandevr of habit 
than for the attractiveness of their flowers, is very large, in- 
cluding the Oaks (Quercus Robur, Q. Cerris, Q. coccinea, etc.), 
Beeches, Elms, Sweet Chestnut, Planes (Platanus orientalis), 
some of the Willows (Salix fragilis and 8. alba), many of 
the Maples (Acer platanoides, A. rubrum, A. Pseudoplatanus 
and A. eriocarpus), the Poplars (Populus tremula, P. alba, 
P. nigra, P. balsamifera, P. angulata, etc.), Hop Hornbeam, 
Planera Richardii, Common Birch, etc.—with simple, entire, 
toothed, or lobed leaves. Amongst large trees with pinnate 
leaves we have the Ailanthus glandulosa, Sophora Japonica, 
Common Walnut (Juglans regia), Black Walnut (J. nigra), the 
Hickories (Carya spp.), and the Ashes (Fraxinus spp.). Decidu- 
ous coniferous trees are not numerous; but there are three well- 
known species, representing as many distinct types, namely, the 
deciduous Cypress (Taxodium distichum), the Common Larch 
(Larix Europa), and the Maidenhair tree (Salisburia adianti- 
folia). Amongst trees of smaller dimensions we may mention :— 
the Hornbeam, Common Alder, Sallow Willow, Liquidambar, 
some of the Maples (Acer Monspessulanum, A. Tataricum, A. 
polymorphum, and A. Pennsylvanicum), Paper Mulberry (Brous- 
sonetia papyrifera), ete.—with simple, entire, or lobed leaves ;
