with small leaves and small clusters of minute flowers; and there is 
one in which the corolla is deeply divided into narrow lobes (var. poly- 
peiala). This plant, which is not at all ornamental, was found near 
Deerfield, Massachusetts, and has been propagated and distributed from 
the Arboretum. A form with broad, handsome, Rhododendron-like 
leaves (var. obtusata) which rarely flowers was found a few years ago 
near Pomfret, Connecticut. These forms, with the exception of var. 
fuscata, are all established in the general Kalmia collection which is 
planted on both sides of Hemlock Hill Road at the northern base of 
Hemlock Hill. This part of the Arboretum where there are other in- 
teresting plants, including the collection of Rhododendrons, is easily 
and quickly reached from the South Street entrance of the Arboretum. 
Syringa yunnanensis. This Lliac from southwestern China is now in 
flower. It has long-pointed, glabrous leaves dull green above and pale 
below, and large, rather open clusters of small creamy white flowers 
faintly tinged with rose color, with an unusual and delicate perfume 
which greatly adds to the attraction of the plant. S. yunnanensis is 
one of the plants introduced by George Forrest through the Bee Com- 
pany of Liverpool and has now been growing in the Arboretum for 
several years. Although it first flowered here in 1913, it has not 
shown its real character as a flowering plant until this season. S. yun- 
nanensis can be seen on the lower side of the path which follows the 
top of the bank occupied by the Lilac Collection. 
Syringa Julianae. This Chinese Lilac has flowered in the Arbore- 
tum every year since 1909 but never so abundantly as this year. In 
the shape of the leaves and in the long slender corolla-tube it has 
something in common with S. pubescens. This, however, is a native 
of the northern part of the empire; it blooms fully three weeks earlier 
here, and the flower-buds are rose color, not purple. The flowers, too, 
of S. Julianae are without the strong perfume of S. pubescens which, 
especially in the evening, is stronger than that of the flowers of any 
other Lilac. S. Julianae is one of the most distinct of the numerous 
Lilacs discovered by Wilson in western China and promises to be a 
useful garden plant here, if for no other reason, on account of the 
lateness of the flowers. It can be seen with all the other Chinese 
Lilacs discovered by Wilson nearly opposite the plant of S. yunnanensis 
on the path at the top of the Lilac bank. 
Caragana Maximowicziana. This is a good addition to the so-called 
Siberian Pea-trees which can be successfully grown in northern gardens. 
It is a shrub with slender, wide-spreading and arching, spiny stems, 
small pinnate leaves and narrow, canary yellow flowers which are pro- 
duced in great numbers and appear later than those of the other Car- 
aganas in the collection. It is a native of northern China and first 
flowered in the Arboretum two years ago when not more than two 
feet high. Plants in flower can be seen in the Shrub Collection and 
among the Chinese plants on the southern slope of Bussey Hill. 
Photinia villosa. This is a small tree or arborescent shrub of a 
genus of the Rose Family closely related to Crataegus and Cotoneaster 
and is widely distributed in eastern Asia. It has thick, dark green 
leaves and white flowers produced in great profusion in compact, many-
