Quercus serrata (Fagaceae), 54433. Oak. From Roches- 
ter,N. Y. Acorns presented by Mr. John Dunbar .Assist- 
ant Superintendent of Parks. "A half -evergreen oak na- 
tive to Japan and Chosen. We have grown it here for 
about twenty years and it seems to be perfectly hardy. 
Two trees fruited quite freely this year, but Dr. Sar- 
gent has no record of any other trees baving produced 
mature nuts in this country. 
''Being of a half -evergreen nature the leaves re- 
main green until very late in the season; sometimes 
they assume a dull yellow color. I think it is one of 
the most ornamental of the different species of oaks 
which have been introduced from Japan." (Dunbar.)

A mygdalus davidiam (Amygdalae eae) ,36664. Peach. From 
Peking, Chihli, China. "I set out 20 or 30 trees on my 
farm in Vermont and top-worked them to different va- 
rieties of peaches and a few plums. They have done 
exceptionally well and the stock apparently has im- 
parted to them some of its hardiness, for the peaches 
which were top-worked on this stock have suffered much 
less from winter injury than many of the others. "(W.H. 
Darrow, Extension Pomologist, Storrs, Conn. February 
17, 1922.) 
Amygdalus persiea (Amygdalaceae) , 41395. Peach. From 
Kaying, Kwantung, China. "Planted 1920, the tree blos- 
somed and set two dozen fruits in 1921. One of the 
most delicious peaches I have eaten; it has the flavor 
of a-hot-house peach and is a beautiful .yellow-pink 
color; the flesh is firm and, being a cling, cans well."

Alta Verapaz, Guatemala. "A very fine plant with beau- 
tiful velvety leaves 9 inches in diameter. The plant 
is easy to grow and mine now has a spread of over 2
