VIBURNUM DILATATUM 
Thunberg’s Viburnum 
Native of China and Japan 
Family CAPRIFOLIACEAE HONEYSUCKLE Family 
Viburnum dilatatum Thunb, Fl. Jap. 124. 1784. 
This is one of the most attractive viburnums of Japan, a country 
- rich in members of this genus. Its flowers, which appear about the 
middle of June in the latitude of New York city, clothe it with a 
mantle of white, and in the early fall the fruit, which is borne in 
great profusion and lasts well through the winter, makes of the 
bush a mass of rich scarlet; the leaves also take on a rich fall color- 
ation, so that this plant is an object of great beauty for many 
months of the year. It is of easy culture, thriving in almost any 
soil of ordinary fertility. Longevity is added to its other desirable 
qualities, as is indicated by the fact that the plant in the New York 
Botanical Garden from which the illustration was prepared was 
secured in 1895 from the Arnold Arboretum. V2burnum dilatatum 
was introduced into England about 1875 by the Messrs. Veitch, 
and has since then become widely spread in cultivation. 
A general discussion of the genus Viburnum, including methods 
of propagation, will be found in volume 4 of this periodical, at 
page 55. To the information there presented it may be added 
that in the northeastern parts of North America there are fourteen 
species native, and three others in the southeastern United States, 
making a total of seventeen species for eastern North America. 
But it is in eastern Asia that the genus finds its greatest repre- 
sentation, about sixty-five species being known from that region. 
Thunberg’s viburnum in habit is an upright shrub up to ten feet 
tall, bearing its white flowers and scarlet fruit in broad flat-topped 
clusters. he branches of the year are clothed with a rather long 
dense pubescence, the older branches finally becoming glabrous. 
The leaves are opposite, each on a densely pubescent stalk com- 
monly less than a half inch long. The outline of the blades is 
oval, broadly ovate or obovate, or adiicaier or nearly so, the apex 
being abruptly pointed and the base rounded; they are densely 
pubescent on both surfaces, especially the lower, in age the pubes- 
cence becoming sparser; they measure commonly up to three
