ville, Tennessee. Sent to France by its discoverer, the elder Michaux, 
it has been in cultivation for more thau a century. One of the first, 
and perhaps the first specimen planted in the United States was stand- 
ing a few years ago in the grounds of the Philadelphia Cricket Club 
near that city. It was planted in Massachusetts, where it is perfectly 
hardy, at least eighty years ago. This tree flowers well in France and 
Germany, but rarely produces flowers in Great Britain where the sun 
is not hot enough to ripen sufficiently the flowering wood. Here the 
trees flower only once in two years and, with few exceptions, all in- 
dividuals planted in the northern states flower the same year. Although 
one of the handsomest trees that can be used for the decoration of 
parks and gardens in the eastern states, the Virgilia seems to be less 
commonly used here than it was seventy-five years ago. Fortunately 
it can still be obtained in a few American gardens. 
Deutzia hypoglauca. This plant was not injured by the severe cold 
of the past winter and has now flowered for three years in the Arbor- 
etum. It is a tall vigorous shrub with erect, much branched stems, 
lanceolate, long-pointed leaves dark yellow-green on the upper surface 
and pale below, and light orange-brown branchlets. The pure white 
flowers are seven-eighths of an inch in diameter and are borne on 
slender drooping pedicels in many-flowered compound, round-topped 
clusters from three to four inches across. The broad, petal-like fila- 
ments, which are rather shorter than the spreading petals and are 
notched at the apex, form a tube rising from the center of the flower 
from which the bright yellow anthers emerge. Deutzia hypoglauca 
was discovered by Wilson in Hupeh but the plants in the Arboretum 
were raised here from seeds collected in 1910 by Purdom on the moun- 
tains of Shensi at altitudes between eight and ten thousand feet above 
the sea-level. This may prove a valuable plant to cross with some of 
the Chinese Deutzias with rose-colored flowers which are not really 
hardy in this climate. It is a handsomer plant than D. parvifiora, 
another Chinese species and an old inhabitant of the Arboretum where 
it has proved to be one of the hardiest of all Deutzias. Sent by the 
Arboretum to Lemoine at Nancy, France, it was successfully crossed 
by him with D. gracilis. The result of this cross was Deutzia Lemoineiy 
one of the handsomest and hardiest garden shrubs of recent creation. 
One of the forms of D. Lemoinei, Boule de Neige, has been unusually 
full of flowers this year. 
The Persian Yellow Rose. This Rose is just opening its flower-buds. 
It is the last of the yellow-flowered Roses which are hardy in the Ar- 
boretum and a few days later than the Harrison Rose. The Persian 
yellow Rose is a dwarfer plant of better habit than the Harrison Rose, 
and the flowers are larger and of better color; and when it succeeds it 
is the handsomest of the double-flowered yellow Roses. It is a form 
of Rosa foetida, a beautiful and too little known Rose of southern 
Russia, the Caucasus and Persia. The so-called Austrian Briar, with 
petals yellow on the outer surface and dark copper color on the inner 
surface, is believed to be a variety of R. foetida (var. bicolor). The Har- 
rison Rose, which was raised in New York many years ago, is believed
