SMALL DECIDUOUS TREES. 137 
There is a variety of this with narrow leaves, which 
blooms more profusely, and the flowers smaller but in-

the Ash, it makes a more beautiful tree, and grows more 
rapidly than on its own roots. 
Cornus. (Dogwood.) 
A genus that contains many native species as well as 
several foreign ones that are cultivated for ornament. 
The only native species that grows large enough to be 
classed among trees is

the leaves expand, gives it a very showy appearance, 
rivaling the well-known Chinese Magnolia (M. conspicua) ; 
trees of twenty to thirty feet high, with fine-grained, very

CorNUS MASCULA is a foreign species of this genus 
which bears edible fruit. 
Craracus. (Huwthorn.) 
There are many species in this genus, few of which attain 
the size of trees, as they seldom grow more than twenty 
feet high. The flowers are white or pale pink, resembling 
the apple, but smaller; fruit variable in size, sometimes
