ornamental plant is Syringa Sweginzowii. This, too, is a tall shrub 
but the branches are not as stout as those of S. rejiexa, and the leaves 
are narrower, pointed at the ends and pale on the lower surface. The 
flowers are produced in broad erect clusters and are pale rose color and 
half an inch long. The flower-buds are of a peculiar brownish green 
color, and as the flowers open gradually from the bottom to the top 
of the cluster the contrast between the open flowers below and the 
closed buds above give this plant a peculiar appearance during the 
week or ten days the flowers are opening. This Lilac was first made 
known through plants raised in the Arboretum of Max von Sivers at 
Riga in Russia from seeds sent from some place in Mongolia or north- 
ern China, the name of which is not recorded. Later it was found by 
Wilson in western China, but the plants growing in the Arboretum 
were obtained from the nursery of Regel & Kesselring in Petrograd. 
S. Komarowii has leaves which resemble those of S. rejiexa but the 
flowers are produced in short, compact, nearly cylindrical clusters nod- 
ding on long stems. The flower-buds are bright red and very conspic- 
uous, and the open flowers are deep rose color. This Lilac sometimes 
blooms profusely when still a small bush. Syringa tomentella promises 
to grow taller than the other new Chinese Lilacs for some of the plants 
in the Arboretum are now nearly ten feet high. The leaves resemble 
those of S. villosa, and the flowers are pale rose color or white, and are 
borne in narrow erect clusters. None of the Arboretum plants have 
ever produced many flowers and S. tomentella promises to be one of 
the least desirable of the new Lilacs as a garden plant. Syringa Juli- 
anae flowers earlier than most of the new Chinese Lilacs and the 
flowers are already fading. As it grows here this is a compact low 
shrub nearly as broad as high, and for several years has covered itself 
with short clusters of rose-colored and white fragrant flowers. Re- 
ated to the Chinese S. pubescens, it blooms much later than that and 
other related species, and is an excellent addition to the list of Lilacs 
which can be grown in our gardens. Syringa Woljii, which has dark 
violet-purple flowers in short compact clusters, is another good garden 
plant in this climate. This species, too, was first cultivated by Von 
Sivers at Riga who obtained it from some place in northern China 
which is not known. The other new Chinese Lilacs in the Arboretum, 
S. Meyeri, S. microphylla, S. pinnatifolia and <S. yunnanensisi have 
comparatively little decorative value and are curiosities rather than 
good garden plants. 
The Yellowwood or Virgilia. This tree, the Cladrastis lutea of 
botanists, is now covered with long drooping clusters of pure white 
pea-shaped flowers which make it one of the most beautiful trees in 
the forests of eastern North America. It is a round-topped tree some- 
times sixty or seventy feet in height, with pale smooth bark which 
resembles that of the American Beech-tree, and large light green com- 
pound leaves which turn clear yellow in the autumn before falling. 
In the forest this is a rare and local tree, and is found growing, 
usually on river cliffs, from western North Carolina to Tennessee, Ken- 
tucky and northern Alabama, and in southern Missouri and northern 
Arkansas. It is most abundant probably in the neighborhood of Nash-
