Geo. B. Newman, Chengtu, Szechwan.

42683. ACTINIDIA CORIACEA. Received from Vilmorin-Andrieux & Co., 
Paris, France. A strong-growing, woody vine native to central China; 
it is useful for covering arbors and pergolas, and for training over 
porches. The leaves are large and leathery, and the clusters of red 
or rarely yellow, sometimes white-margined flowers, and small, spotted 
berries, make it highly ornamental. Its cultivation is practicable 
only in mild-wintered regions.

ALEURITES FORDII. Tung-Oil Tree. From China. From the seeds of 
this tree is obtained the valuable drying oil known as tung oil, or 
China wood-oil, used in the manufacture of high-grade paints, varnishes, 
and linoleums and for many other purposes. The seeds are not 
edible. The species is useful as a street and shade tree, being a 
rapid grower with catalpalike leaves, and producing a profusion of 
pinkish white flowers in the spring just as the leaves begin to expand. 
A deep sand-clay loam is preferred by this species, but it grows well 
in other well-drained soils that produce ordinary crops. It is already 
grown scatteringly in the Southern States and in the warmer parts of 
California; it does not thrive where the winter temperature falls much 
below 15° F. Tung oil is being used more extensively each year, and 
the annual imports now amount to more than 10 million gallons. The 
oil has become so important in the industries mentioned that the 
question of a steady supply is now a matter of serious concern to 
manufacturers. Due to recent disturbances, the supply of the oil from 
China has been much interrupted and the price has occasionally risen 
to three times what was formerly considered normal. In view of the 
foregoing and the further fact that the imported product is nearly 
always adulterated, it seems worth while for Southern farmers to experiment 
on a small scale with the cultivation of the tung-oil tree.

56636. ALNUS NEPALENSIS. Alder. From Yunnan, China. Collected by 
J. F. Rock, Agricultural Explorer. A tree from the mountains of Yunnan, 
where it sometimes reaches 70 feet in height, and has a trunk 3 
to 4 feet thick. It is a rapid grower, said to thrive under rather 
adverse conditions. For trial in the southern United States.

55411. AMERIMNON SISSOO. Sissu. From Dehra Dun, India. Presented 
by R. S. Hole, Forest Botanist. A splendid leguminous forest and timber 
tree native to subtropical slopes of the lower Himalayas. It is 
highly esteemed as an ornamental tree for street planting, as well as 
for its very durable wood which seasons well, does not warp or split 
and is strong and elastic. The thin layer of sapwood is white, while 
the heartwood is very hard and brown with darker longitudinal veins. 
Introduced for trial in southern Florida.

39434. AMPELOPSIS ACONITIFOLIA. From Pingyanfu, Shansi, China. 
Collected by Frank N. Meyer, Agricultural Explorer. This is a handsome 
vine related to the Virginia creeper, with cut-toothed leaves and 
yellow berries. It is valued as a porch and pergola vine on account
