a length of a foot, are rather cylindrical, and av- 
erage a weight of 4 or 5 pounds in favorable seasons. 
The interior of the starchy root is a rich light yel- 
low and turns dark brown when exposed to the air. It 
is smoother and more even grained than the water yams 
and not less so than the roots of the "White Guinea" 
or the "Potato" yams. It is rich yellow and of good 
texture when cooked. The flavor is pleasant and com- 
pares favorably in richness with the best yams. The 
vines of this variety are not angled; they are small 
and very strong, and made a moderately vigorous growth.

"In addition to the data on quality given by Mr. 
Kinman, it may be noted that this yam has a slightly 
bitter taste; on this account special methods of cook- 
ing may sometimes be required. It is said that the 
bitterness is more noticeable in immature tubers than 
in fully mature ones." (R. A. Young.)

Hydnocarpus anthelminthiea (Flacourtiaceae) , 54726. 
From Chiengmai, Siam. Seeds collected by Mr. J. F.Rock, 
Agricultural Explorer, of the Bureau of Plant Industry. 
"This is a large tree about 50 to 80 feet in height, 
found along stream beds north of Chiengmai in northern 
Slam, and is apparently a new variety. It differs from 
the southern Siamese form in the fruit which is chest- 
nut brown and neither velvety nor strongly lenticel- 
late. The staminate flowers are on long pedicels and 
have no rudimentary ovary, but the pistillate flowers, 
which are on shorter pedicels and occur in the axils 
of young (this year's) shoots, have five short, sterile
