          56304. COTONEASTER sp. From Yunnan, China. Collected by J. F. Rock, 
Agricultural Explorer. An ornamental, prostrate shrub from the mountains 
of Yunnan. It has small, elliptical leaves, dark green in color, and 
small, red berries of attractive appearance. Not hardy in the northern 
parts of this country.

56305. CUPRESSUS sp. Cypress. From Yunnan, China. Collected by J. F.
Rock, Agricultural Explorer. A promising cypress of rapid growth, with 
foliage of a bluish cast. In its native region it grows to 40 or 50 feet 
in height. While it may not be sufficiently hardy for cultivation in the 
northern part of this country, it should be tested in the Southern States 
and on the Pacific coast, where it seems likely to find conditions 
altogether congenial.

56117. DICHOTOMANTHES TRISTANIAECARPA. From Yunnan, China. Collected by J. F. Rock Agricultural Explorer. A spreading shrub, reaching to 15 feet 
in height, with large clusters of red and yellow berries. Suggested for 
trial as an ornamental plant in the Southern States and on the Pacific 
Coast. It probably will not prove hardy as far north as Washington, D. C.

54983) DIOSCOREA ALATA. Greater Yam. Four commercial varieties (at 
present not separately identified) of yams of excellent quality from the 
West Indies. There are slight differences between them in shape or quality 
of tuber. They have been tested for several years in Florida and more 
recently in the Gulf regions of nearby states, and are shown to be suited 
for cultivation there in several types of deep and fairly rich loam soils. 
The vines are 4-angled and somewhat winged; they resemble those of 
S.P.I. No. 37943, but the tubers are of better quality. Yams of this 
class are much in demand on the market, and the commercial supply is as 
yet very inadequate.

46801. DISCOREA ALATA. Greater Yam. A West Indian variety of yam grown 
for several years near Miami, Fla. The tubers, which are white fleshed 
and drier than those of most varieties, are of good flavor though often 
rough and irregular in shape. Tubers sometimes reach a weight of 15 pounds 
in rich sandy loam or on well-drained muck soils.

56389. DIOSPYROS KAKI. Kaki or Japanese persimmon. From Yokohama, Japan. 
Purchased from the Yokohama Nursery Co. The importance of securing desirable 
rootstocks for the Japanese persimmons cultivated in this country has led 
to the importation of this variety, which is used by the Japanese 
extensively. It is said to be a semiwild kaki, which bears a long, 
pointed fruit of little value. As a rootstock for other and better sorts, 
it is hoped that it may prove vigorous and long-lived. It should be tested 
in California and the southern States.
