by R. S. Hole, Forest Botanist, Dehra Dun.

56307. DEUTZIA sp. From China. Collected by J. F. Rock, Agricultural 
Explorer. A shrub of this handsome genus found upon the Likiang Snow 
Range, in Yunnan.

37943. DIOSCOREA ALATA. Greater, or Ten-month's Yam. A West Indian 
variety of the true yam, sparingly cultivated in Florida. It is not 
related to the sweet potato, some varieties of which are called yams. 
The tubers of this plant, which sometimes reach a weight of more than 
10 pounds each, are white-fleshed, and in composition are similar to 
the white potato, from which they can scarcely be distingushed when 
properly cooked. Yam tubers, when carefully handled, may be stored for 
a long period without appreciable deterioration. For cultivation a 
deep mellow soil and a growing season of 9 to 10 months are required, 
but the plant is a handsome vine and may be grown for porch decoration 
where the season is much shorter. This yam deserves much wider cultivation 
in Florida for home use and for markets.

39705. DIOSCOREA ALATA. Guam Yam, or Dago Haya. From Guam. A 
variety of the greater yam with purple inner skin and white flesh sometimes 
slightly tinged with purple. The tubers are often large and of 
irregular shape. The flesh darkens somewhat when cooked, but posseses 
a rich flavor. The vine is easily distingushed from that of the preceding 
variety (No. 37943) by the reddish maroon color at each end of 
the petiole or leaf stalk.

46801. DIOSCOREA 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.

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.

13842. DIOSPYROS KAKI. Kaki or Japanese persimmon. Variety Mamegaki. Received from the Yokohama Nursery Company, Japan. A very good, 
late-keeping variety, the flesh of which is dark and nonastringent
