leaf. Thus the palmatum group have five-lobed, the 

 septemlobum group seven-lobed, and the dissectum 

 group variously-lobed leaves. It is difficult to select 

 from among so many, but palmatum decompositum, 

 septemlobum elegans, and dissectum roseo-marginatum 

 are worth mentioning. Any reference to the Maples 

 must include Acer Negundo variegata, a small tree with 

 green and white leaves that is admirable for enlivening 

 shrubberies. The Norway Maple, Acer platanoides, is a- 

 useful tree with yellow flowers in spring, and there is a 

 popular form of it called Schwedleri, the young leaves of 

 which are reddish. 



Little planted as a garden tree, the common Ash, 

 Fraxinus excelsior, has weeping forms which are some- 

 times used. Two may be named : pendula and Went- 

 worthii ; the former is wholly pendulous, the latter has 

 a stiff leader. There is a silver variegated Ash, F. e. 

 argenteo-variegata. F. ornus is the Flowering Ash. 



The Planes are of trivial importance as garden trees, 

 although valuable for street planting, particularly in the 

 case of the common London Plane, Platanus acerifolia. 

 There is a good variety of this called Siittneri. 



Nor are the Poplars of great importance in the garden. 

 The white Poplar or Abele tree, Populus alba, may be 

 commended for moist sites, and there is a good pyramidal 

 variety of it named pyramidalis, which is suitable for 

 the garden. The black Poplar, Populus nigra, is a good 

 screen or shelter tree, but has no particular beauty ; its 

 variety pyramidalis is the well-known Lombardy Poplar, 

 a stiff, upright tree entirely devoid of beauty, and only 

 planted to the enormous extent it is because when headed 

 a few feet from the ground it throws hundreds of young 

 shoots along the main stem from the ground upwards, 

 and therefore serves as a means of providing a quick
