DECIDUOUS TREES. 435 



Naked young wood brown and green. Size, ten to fifteen feet in 

 height, and greater diameter. 



The Panicled-flowered Dogwood, C. paniculata, is a tree or 

 shrub of more upright growth, with a profusion of white flowers in 

 July and August, and purplish young wood. Height, fifteen to 

 twenty feet. On account of its compactness it is considered one 

 of the best for small grounds. 



The Round-leaved Dogwood. Comus terdnata. — A species 

 noted for its large circular wavy leaves, which are downy on the 

 under side, and for its rough warted branches. Flowers small, 

 white, in June and July. Fruit white when ripe, in October. 

 Young wood slightly tinged with red. Height five to ten feet. 



The Variegated-leaved Dogwood, Comus mascula variegata, 

 is a pretty variation, with leaves striped or blotched with white, 

 interesting to persons who fancy trees which sport in this manner, 

 and considered one of the most desirable variegated-leaved shrubs 

 in cultivation. 



The Siberian Golden Variegated-leaved Dogwood, C. 

 aurea variegata, has a yellow stripe on its leaves, and bark striped 

 with red and yellow. The latter is quite curious. 



All the foregoing varieties have their leaves in opposite pairs. 

 The following has alternate leaves : 



The Alternate-leaved Dogwood. Comus altemifolia. — ^We 

 are not familiar with this variety in cultivation. Loudon thus, 

 speaks of it : " This species is easily known from every other, even 

 at a distance, by the horizontal, umbelliferous character assumed by 

 the branches, which are dichotomous, with clusters of leaves at the 

 joints, and the general color is a lively green. The leaves are gen- 

 erally alternate, but not unfrequently opposite. Flowers white. 

 May to July. Fruit purple, ripe in October. Decaying leaves red- 

 dish-yellow. Naked young wood greenish or reddish brown." It 

 seems doubtful if Loudon were familiar with the horizontally um- 

 belliferous character of our Cornus florida, or he would not have 

 thought of making this trait a distinguishing one of the Cornus. 

 altemifolia ; it is a characteristic of all the arboreous dogwoods.
