HARDY PICTORIAL TREKS. 261 



Philadelphus coronarius variegatus (the Variegated 

 Syringa). Deciduous. Height, 3 feet. Leaves green, 

 broadly margined with white. A beautiful dwarf shrub. 



Populus argentea vera (the Silver Poplar). Deciduous. 

 Height, 60 feet. Leaves and bark much whiter than those 

 of the Abele Poplar. A beautiful cool-looking tree in 

 summer, worthy of very general adoption. 



Shepherdia argentea. Deciduous. Height, 6 feet. 

 Leaves like frosted silver. A beautiful dwarf shrub. 



Tilia argentea (the Silver Lime). Deciduous. Height, 

 40 feet. Leaves large, whitish above, quite white under- 

 neath, very effective when the leaves are moved by the 

 wind. 



Ulmus campestris variegata (the Variegated Elm). 

 Deciduous. Height, 40 feet. Leaves white and green. 

 Very effective. 



Under the head of colour we must rank those trees 

 whose leaves change before their fall in autumn. The 

 most effective are : Red Acer rubrum (Scarlet Maple), 

 Berberis vulgaris, Cornus alba (Dogwood), Liquidambar, 

 Quercus coccinea (Scarlet Oak), Rhus Cotinus "(Venice 

 Sumach), Rhus typhina (Stag's-horn Sumach), Spiraea 

 ariaefolia, Spiraea prunifolia fl. pi., Viburnum Lentago, 

 Viburnum Opulus (Gueldres Rose), Crataegus prunifolia. 

 Yelloiv ^Esculus Hippocastanum (Horse Chestnut), Acer 

 platanoides (-Norway Maple), A. Pseudo-Platanus (Syca- 

 more), A. saccharinum (Sugar Maple), Amelanchier 

 Botryapium (Snowy Mespilus), Betula (Birch), of sorts, 

 Cerasus Padus bracteosa '(Bird Cherry), Cerasus Virgin- 

 iana, Crataegus (Thorns), of sorts, Gleditschia triacanthos, 

 Kolreuteria paniculata, Liriodendron tulipiferum (Tulip 

 Tree), Magnolia tripetala, Morus alba, Pavia flava, 

 Populus (Poplars), of sorts, Salisburia adiantifolia, 

 Syringa vulgaris (Lilac), and Tilia europaea (Lime). The 

 colours of the decaying leaves were less vivid than usual 

 last autumn, owing probably to the quantity of rain that 

 fell late in summer.
