210 DESCRIPTIONS OF THK SHRUBS 



and the berries grow together in a globular head. The American species 

 blooms before the leaves are fully expanded, while the flowers of the 

 Japan species appear after the leaves. Both are hardy to Massachu- 

 setts. 



All the other shrubby forms have the clusters of flowers more open and 

 without large conspicuous bracts. The true flowers of all the species are 

 small and have four petals to the corolla, four teeth to the calyx, and four 

 stamens. The fruit is a drupe-like berry with one stone in the center 

 and thin flesh. Much of the beauty of the species is due to the bright- 

 colored berries which they bear, though the autumn coloring of the 

 foliage adds to the attractiveness of the group. The bright colors of the 

 twigs of some species, when the leaves have dropped, give winter effects 

 of great beauty. 



In general, the common name Cornel, below, may be changed to 

 Dogwood. [Twig cuttings; layers.]
