its genus, and one of the most beautiful of the small flowering trees of 
western China. The different forms of the so-called European Walnut 
(Juglans regia), introduced by Wilson, and the distinct J. cathay ensis, a 
tree with splendid foliage and nuts resembling those of the American 
Butternut, are uninjured by the cold. Populus lasiocarpa, which has 
lived in the Arboretum uninjured during the past two years, adds a very 
remarkable and hanc some species to the large group of these trees which 
can be cultivated here. A still more beautiful species brought back by 
Wilson on his last journey and still unnamed has passed the winter with- 
out injury. Even the Liquidambar of central China, L. formosana , is 
uninjured and may prove hardier here than the native species which suf- 
fers in eastern Massachusetts except in favorable positions. 
The greatest of all the Hazels, Corylus chinensis , judging by the 
plants at this time, gives promise of becoming an important addition to 
the ornamental trees which can be cultivated here. With an average 
height of from sixty to eighty feet and a girth of trunk of from eight to 
ten feet, in favorable situations on the mountains of Hupeh it attains a 
height of more than a hundred feet with a trunk five feet in diameter. 
There is much interest in the various forms of Cherry raised from seeds 
sent home by Mr. Wilson, who found an unexpectedly large number of 
species in several of the groups of the genus Prunus to which the Cherries 
belong. They are nearly all quite new to science and of course have not 
been found before in gardens. Thirty of these new species or varieties 
have passed through the winter uninjured, and only two species, which 
will probably not live here, have suffered. Among these species are a num- 
ber of great beauty and this group perhaps is the most interesting of the 
deciduous-leaved trees obtained by Mr. Wilson during his first journey. 
The Hemlock of western China, Tsuga yunnanensis, has now lived for 
two years in the Arboretum. This is one of the largest and most widely 
distributed of the conifers of China. The fact that it grows with the 
Spruces and Firs which cover the mountains of the Tibetan frontier indi- 
cates that these trees may also be hardy in this climate. The introduc- 
tion of these conifers was the object of Mr. Wilson's last journey to 
China, and they are now growing in the Arboretum and in many public 
and private collections. 
It can be said that generally the new Chinese species of Oak, Beech, 
Birch, Willow, Poplar, Pear, Maple and Ash, besides some of the less 
well known genera like Idesia, Euptelea, Poliothyrsus and Eucommia, 
judging by the experience of the past year, are likely to succeed here and 
it is probably reasonable to hope that not less than seventy-five new 
species of trees will be added to our plantations by Mr. Wilson’s first 
journey to China. In another issue something will be said of the condi- 
tion of some of the new Chinese shrubs. 
There are already many flowers to be seen in the Arboretum. The 
Elms, and the Red Maple, the Poplars and some of the Hazels are in 
flower. The flowers of the Silver Maple are already falling. Many of 
the Alders are now covered with their delicate flowers. One of the most 
interesting of these is the Japanese Alnus tinctoria. This is a medium 
sized shapely tree with smooth pale bark and large dark green leaves. 
Two specimens can be seen on the right-hand side of the Meadow Road 
close to the walk and in front of the Linden Group. They were raised
