usual interest in that they come from the extreme northern part of 
China, a region of severe winters and hot summers, generally similar 
in climatic conditions to the Northern Great Plains area of the United 
States . 
Though one of the following poplars is not new to this country, 
they will tooth be propagated for trial. It is possible that Mr. 
Woeikoff's form of Populus moximowiczii will prove slightly different from 
the one previously distributed by this Office. 
58483. populus maximowiczh. A handsome, stately poplar which is 
said to reach large size in its native country, Manchuria. In the 
United States, it is one of the few large deciduous exotic trees which 
can be recommended for general planting in extremely cold sections. 
John Dunbar, assistant superintendent, Department of Parks, Rochester, 
N.Y. , who has grown this tree for some years, and who has been instru- 
mental in effecting its dissemination in this country, says that it is 
successful on dry gravelly soil where Norway spruce and white ash are 
failures. During the first eight years, it increases in height at the 
rate of 3 to 5 feet annually. Its foliage 'is of striking appearance. 
Unlike that of many other poplars, it hangs on until late in the season. 
The specimens grown in this country up to the present time have shown 
remarkable freedom from borers and from several rather obscure diseases 
which affect other poplars, and which are generally known as "canker." 
Unless all indications fail, Populus maximowiczii will become an important 
shade and windbreak tree in the northernmost parts of the United States. 
58484. populus suaveolens przewalskii. Mr. Woeikoff reports this 
to be a fairly common tree in towns and villages of northern China, 
easily distinguishable from others by its close, compact habit. For 
hot, dry climates it is recommended as highly valuable. While it is 
of slower growth than Populus maximowiczii, it eventually becomes a large 
tree of ornamental appearance. The small, oval leaves are prominently 
whitened beneath. 
PRUNUS armeniaca ( Amygdalae eae ) , 58809. Apricot From Tripoli, 
North Africa. Seeds presented by Dr. E. 0. Fenzi. In forwarding seeds 
of this curious variety of apricot, Dr. Fenzi remarks that it is known 
locally as 'ain thor' (bull's eye) and 'bergsam. ' He describes it as 
"a very large tree, taller and more vigorous than other kinds; leaves 
thin, irregularly toothed; fruit globular, with hardly any suture, weight 
40 grams, diameter 40 mm.; skin scarcely tomentose, reddish yellow, 
adhering closely to the flesh, which is more juicy than that of other 
apricots, clings to the stone, and suggests a plum in flavor. It is 
not common in Tripoli." 
This form should prove interesting for trial in the western United 
States, not alone for its fruit, but also as a possible stock-plant on
