of the dungonlate from Manila. Presented by 0. W. Barrett, 
Chief, Division of Horticulture, Philippine Bureau of 
Agriculture. "A medium- si zed tree with a dense crown, 
leaves entire, leathery, dark above and silvery beneath. 
The wood is very hard and durable and is classed among the 
best of the Philippine hardwoods. The tree is a good 
ornamental and makes an excellent windbreak. It succeeds 
on moist land and grows well even in the proximity of salt 
water." (Barrett.) For distribution later. 
IPOMOEA BATATAS. ( Convolvulaceae . ) 35280-281. Tubers

JUGLANS MANDSHURICA. ( Juglandaceae . ) 35303. Seeds 
of the Manchurian walnut from Mukden, Manchuria. Received 
from Mr. Frank N. Meyer, Agricultural Explorer. "The Man- 
churian walnut is a stately timber tree, occurring in 
Manchuria and Japan. It is very sensitive to late frost 
and on that account has proven to be a difficult tree to 
grow away from its native countries." (Meyer.) For 
distribution later. 
LOVOA SWYNNERTONII . (Meliaceae.) 35459. Seeds of brown 
mahogany from Mount Silinda, Melsetter, Rhodesia. Present- 
ed by Mr. 0. J. Omer, American Board Mission in South 
Africa through the Forest Service of this Department. 
"This tree produces a splendid dark brown wood of great 
strength and durability and is found only in our forest 
here at Mount Silinda, the only forest of large trees in 
Rhodesia. The tree grows to a height of 150 to 200 feet, 
diameter 5 to 8 feet, a 150 foot tree requiring about a 
hundred and fifty years for growth. It is, I understand a 
true mahogany, and it is because of its rarity that I 
thought you might take an interest in experimenting with 
it in America. The temperature here varies from about 30° 
F. in the cold season to about 80° in the shade during the 
summer months, rainfall 70 inches, more than half of this 
falling during the three summer months, elevation 5000 
feet, distance to sea one hundred and fifty miles, pre- 
vailing winds from the sea." (Omer.) "It is a fact worth 
mentioning that other trees from Rhodesia have done pecul- 
iarly well in Florida . " (Fairchild ) For distribution later.
