Catalpa bungei (Bignoniaceae) , 53989. Prom Nanking, 
Kiangsu, China. Seeds presented by Mr. J. Lossing Buck, 
acting dean, College of Agriculture and Forestry, Uni- 
versity of Nanking. "Seeds collected in the first Ki- 
angsu Provincial Forest Station, Ming Tomb, Nanking. A 
tree with white, pink-dotted flowers which are edible 
when cooked; the bark and leaves are used in medicine. 
The soft, light wood is easily split when newly cut, 
but durable when thoroughly dried; it is used mostly 
for building purposes and for making furniture, carts, 
coffins, window sashes, and for carving. It would prob- 
ably be valuable for fence posts." (Buck.) 
Datura sp. (Solanaceae) , 54049. From Ibarra, Ecua- 
dor.. Seeds collected by Mr. Wilson Popenoe, Agricultu- 
ral Explorer. "(No. 625a. Hacienda La Rinconada.) 'Huan- 
tuc . ' >A yellow-flowered form of the common arborescent 
Datura which is cultivated about the huts of the Indi- 
ans throughout the Ecuadorean highlands. The plant some- 
times grows to 15 or 18 feet; its tubular flowers are 
about 6 inches long, 2 inches broad at the 'mouth, and 
of a rich deep-yellow color. The plant is worthy of tri- 
al as an ornamental in protected situations throughout 
southern California, and in southern Florida." (Popenoe.) 
Dioseorea batatas (Dioscoreaceae) , 54048. Yam. From 
Hereford, England. Tubers presented by Dr. H. E, Durham, 
Dunelm. "Chappellier . " The tubers are club shaped, 
tapering to a finger size at the upper part, and when 
grown in the open are generally about 9 to 10 inches 
long and weigh 12 bo 14 ounces when fully grown. Occa- 
sionally twin tubers develop on a single plant, but they 
are then of medium size. This yam may be multiplied 
either by means of cuttings of the tuber or by means of 
bulbils. The size of the eventual tuber seems to depend 
a great deal upon the size of the piece from which the 
plant was grown. By far the most important mode of mul- 
tiplication is by bulbils . (Adapted from an article on 
"The Hardy Yams," by Dr. H. E. Durham, The Gardeners' 
Chronicle,' ser. 3, vol. 69, p. 18.) 
"The stem of the vine is roundish; the leaf blade 
is heart shaped, smooth, upper surface shining, - with 
reddish purple at base of blade." (R. A. Young.)
