Galloway: New Pear Stocks 
stock purposes. Fig. 10 shows the habit 
of the seedlings in the nursery row. 
We have budded eight or ten of our 
principal varieties ef pears on this 
stock. Not more than 30% of the 
buds took. The bark is tough and 
frequently refuses to “slip” easily. 
In striking contrast there is shown in 
Fig. 11 a cultivated form of the Usuri 
pear found by Meyer in 1917, in the 
Chihli Province, China. 
Kuan li or Chinese Water Pear, 
S. P. I. No. 44235 (see Fig. 11) —This 
pear unquestionably belongs to the 
Usiuriensis group. Meyer reported it 
as having small fruits flattened some- 
what like an apple and of a rusty, 
greenish color. He sent in but one 
lot of seed of 17 ounces. From these 
seeds several thousand seedlings have 
been grown and tested as stocks at 
several places. Our first tests were 
with grafted stocks. All the pears 
worked on this stock, including Bartlett, 
Clapp’s Favorite, Anjou, Dutchess, Law- 
rence, Seckel, Sheldon, Howell, Clari- 
geau, and others, are doing very well 
in the nursery row. Unfortunately, 
the source of further seed supply from 
China is doubtful. In the maze of 
Chinese pears it is questionable if 
anyone except an expert could relocate 
the type from which Meyer obtained 
his original supply of seed. In order 
to preserve this valuable type of pear 
we have had top-worked, at the Chico, 
Cal., Station, a part of an old pear 
orchard to the Kuan hi, and within a 
year or two we should be getting seed 
from this source. We shall also be 
prepared at an early date to furnish 
budwood of this pear to those who may 
desire to propagate it for seed produc- 
tion. We place the Kuan li as one of 
our most promising pear stocks. 
The Chinese Saw-leafed Pear, Pyrus 
serrulata, S. P. I. Nos. 34567 and 45832 
(see Fig. 12).—This pear, first collected 
by Wilson in 1907 in the Hupeh Provy- 
ince, 800 or 900 miles west and south 
of Shanghai, was again found by 
Reimer near Ichang, China, in 1917. 
Ichang is in Hupeh Province. Reimer 
found the pear about 15 miles northwest 
of Ichang at elevations from 3,000 to 
29 
3,700 feet. Its growth in the nursery 
compares favorably with the Kuan li. 
It is affected but slightly with leaf- 
blight, holds its foliage well in our hot 
summers, and has a long budding season. 
Our plants are from seeds sent by Mr. 
Reimer. The species does not appear 
to be common, and for this reason, if 
it should prove on further trial to be a 
useful stock, sources of supply should 
be established here. Authentic seed 
may be obtained from the Arnold 
Arboretum, but the supply there is 
naturally limited. We shall be in 
position to supply budwood in limited 
quantities from our collection. Buds 
from our principal varieties of pears 
worked upon this stock took well. 
It is too early to determine the value 
of the stock in producing an ideal 
nursery tree. 
The Birch Leaf Chinese Pe Pyrus 
betulaefolia, S. P. I. No. 21982 and other 
S. P. I. Nos. (see Fig. 13).—This pear 
has come to the Office of Foreign Seed 
and Plant Introduction from a number 
of places and has been listed under 
several 5. P. I. numbers. Meyer col- 
lected it several times and Reimer 
sent in seeds of it. According to the 
late Jackson Dawson, it came to the 
Arnold Arboretum from the mountains 
near Pekin, China, in 1882. Fine speci- 
mens are now growing in the Arboretum. 
The tree occurs in many parts of China, 
and supplies of seeds for commerical 
purposes would not be difficult to get. 
Reimer reports it as being more or 
less susceptible to fire-blight. In the 
east we have never seen it blighted. 
No attacks of blight, so far as we are 
aware, have appeared on the trees at 
the Arnold Arboretum, and these are 
now more than thirty years old. The 
tree has proved practically free from 
leaf blight. It is a vigorous grower 
and is capable of being budded any 
time from July to the middle of Sep- 
tember in the region around Wash- 
ington. According to Reimer it is 
extensively used in China as a stock, 
where it is readily grafted, making a 
good union and producing vigorous 
trees. The pear can be readily grown 
from cuttings. Fig. 13 shows the re-
