Deciduous Trees. 603 



2. Trees having their foliage variegated with white and 

 green. Turkey Oak (Quercus Cerris variegata), Beech (Fagus 

 sylvatica foliis argenteo-variegatis), Elm (Ulinus campestris 

 elegantissima), Elseagnus Japonicus albo-variegatus, Negundo 

 fraxinifolia variegata. 



3. Trees with coloured foliage. The most striking of this 

 limited group is the Purple Beech (Fagus sylvatica purpurea). 

 The Copper Beech (F. s. cuprea) has dull reddish-brown 

 leaves, and is not nearly so handsome. Another very handsome 

 tree is the Scarlet Oak (Quercus coccinea), whose ample foliage 

 changes to a brilliant scarlet hue towards autumn. Several 

 other trees might be enumerated as worthy of consideration 

 in planting, on account of the colour of their foliage. The 

 Purple-leaved Sycamore, the Purple-leaved Elm, and the Abele 

 (Populus alba), whose foliage is snowy white beneath, and Elae- 

 agnus argenteus, with silvery glistening scales, are examples. 



4. Trees with brightly coloured bark on the young branches. 

 --The Grold-barked Ash and the scarlet and yellow twigged 



varieties of the Lime are very distinct and beautiful, more 

 especially the Scarlet-twigged Lime. 



5. Trees ivith cut or dissected foliage. There is scarcely a 

 genus, or even a species, of cultivated trees that has not produced 

 abnormal variations of foliage, from simple to deeply divided 

 or cut. Some of these aberrations are very ornamental, whilst 

 others can only be described as ugly monstrosities. Very 

 handsome cut-leaved varieties of Beech, Alder, Elm, Lime, 

 Horse-Chestnut, Sweet Chestnut, and Oak, are described or 

 mentioned in the descriptive portion of this work. There are 

 three or four species of trees which deserve special notice on 

 account of the great number and diversity of the varieties 

 they have produced, viz., Ulmus campestris, U. montana, 

 Eobinia Pseudacacia, and the elegant Japanese Acer poly- 

 morphum. The varieties of these trees may be counted by 

 scores, or even hundreds in the case of the Robinia. A selec- 

 tion of the most distinct and ornamental is given under the 

 respective genera. 



6. Weeping Trees. Under this head we include only those 

 forms in which the main branches as well as the ultimate 

 branchlets are pendulous. Until quite recently the Weeping 

 Aih and Weeping Willow were the only trees of this class 

 commonly seen. Now, however, the number in cultivation has 

 increased from units to tens. But many of them, like the 

 variegated and cut-leaved varieties, are mere degradations of
