Elaeis guimensis (Phoenicaceae ) , 48001 to 48010. 
Oil palm. From Buitenzorg, Java. Seeds presented by 
Dr. P. J. S. Cramer, chief, Plant Breeding Station. 
"I ammailing seeds of E. guineensis, which were collected 
from trees grown in our garden at Sumatra." (Cramer.) 
This palm is very Important economically. The 
fruit is used by the natives for food; the leafstalks 
and leaves for thatching houses; and the fleshy outer 
layer and kernels of the fruit each yield a commercial 
oil,- that from the fleshy part being the ordinary 
palm-oil used in the manufacture of soap and candles, 
and that from the kernels being the white or nut-oil 
used for making margarine or artificial butter. (A- 
dapted from MacMillan, Handbook of Tropical Gardening 
and Planting, p. 538.)

Juglans eathayensis ( Juglandaceae ) , 48014. Prom 
Rochester, N. Y. Seeds presented by Mr John Dunbar, 
assistant superintendent of parks. "This Juglans Is 
said to grow 70 feet tall, but it does not show any 
tendency to be arborescent here. Our plants, which 
were received from the Arnold Arboretum in 1911, are 
about 10 years old, 8 feet tall, and bushy in habit. 
They began bearing two years since. The nuts germi- 
nate readily." (Dunbar.) 
Mimusops kauki ( Sapotaceae ) , 48011. From Buiten- 
zorg, Java. Seeds presented by Dr. P. J. S. Cramer, 
chief, Plant Breeding Station. Seeds from big fruits. 
The taste resembles very much that of Aehras sapota, but 
the fruit is not eaten very often by Europeans. It is 
a tree that likes to grow near the sea." (Cramer.)
