102954. PLATYCARYA STROBILACEA. Juglandaceae. From China. Collected in Lu Shan, 
Kiangsi Province, and presented by A. N. Steward, University of Nanking. A bush or 
small tree or rarely a tree over 60 feet high, with thick dark deeply furrowed bark. 
The moderately thick branches form a rounded or flattened crown. The leaves, 12 
inches long, are composed of 9 to 17 sessile, doubly serrate leaflets, and the brown 
oval cone—like fruits are over an inch long. For trial from the Ohio River south= 
ward. (Glenn Dale, Md.) 
62111. POPULUS GENEROSA. Poplar. From Kew, England. Presented by the Director, 
Royal Botanic Gardens, Kew, through Dr. David Fairchild, Bureau of Plant Industry. 
This hybrid poplar is intermediate in characters between its parents (Populus angulata 
and P. trichocarpa.) The leaves are coarsely serrate and pale gray beneath. The 
tree is a rapid grower and unusually vigorous. For trial in the upper south and in 
all but the coldest parts of the northern states. (Glenn Dale, Md.) 
68170. POPULUS MAXIMOWICZII. Japanese poplar. From Jamaica Plain, Mass. Cuttings 
presented by the Arnold Arboretum. A very fast-growing and stately tree native to 
N. E. Asia. It will succeed in the coldest portions of the United States on the 
poorest and driest soils and at all times it makes phenomenally rapid growth. Its 
leaves, which are handsomely crinkled like those of Rosa rugosa, appear very early 
in the spring and remain longer in the autumn than those of almost any other decidu- 
ous plant. The tree is said not to be attacked by borers or seriously by leaf-— 
eating insects. It is recommended as a shade tree and windbreak generally, es— 
pecially for the northwest plains country. (Glenn Dale, Md.) 
92522. POPULUS NIGRA BETULIFOLIA.* Poplar. From Spain. Procured from Juan Levya, 
la Quinta, Granada. Spanish name Chopo. A form of poplar, striking because of the 
almost complete absence of true lateral branches, the stems being clothed with 
twigs which, as is common in poplars, are sooner or later thrown off by separative 
layers near the base. Because of this habit of growth, the trees can be planted very 
close together and, as they are rapid growers, they yield an enormous amount of 
wood. For trial in all except the coldest parts of the northern states. (Glenn 
Dale, Md.) 
58484. POPULUS SUAVEOLENS PRZEWALSKII. Poplar From Echo, Kirin Province, Manchuria. 
Budwood presented by the Director, Experiment Farm. This is a rather common tree 
in the towns and villages throughout northern China; it is easily distinguished by 
its close compact habit. The rather small, oval leaves are prominently whitened 
beneath. While the tree is comparatively slow growing, it eventually attains large 
size and it has distinct merit as an ornamental. The tree is said to have especial 
value for hot dry climates, and it also endures considerable cold. For trial through— 
out the northern states. (Glenn Dale, Md.) 
101291. PRATIA ANGULATA.* Campanulaceae. From New Zealand. Obtained from A. 
Wilkinson, Tauranga. A slender creeping herbaceous perennial forming broad matted 
patches. The stems are 2 to 7 inches long, the rather fleshy ovate to orbicular 
leaves, less than one half inch long, are sinuate-dentate, and the auxillary flowers, 
less than 1 inch long, are white with purple streaks. It is native to New Zealand. 
For trial in the milder parts of California and in the Gulf region. (Chico, Calif.)
