          the leaf buds, boiled like spinach, are eaten by the Chinese.

49746. PITHECOLOBIUM TORTUM. Black-bead Tree. From Guatemala. 
Collected by Wilson Popenoe, Agricultural Explorer. A handsome medium-
sized tree, producing an abundance of small, feathery yellow flowers, 
followed by curious leguminous fruits. In Guatemala, where it is called 
aripin, it blooms during the winter. It should be tested in the warmest 
sections of the United States.

57273. PITTOSPORUM FLORIBUNDUM. Presented by G. H. Cave, director, 
Lloyd Botanic Garden, Darjiling, India. An ornamental tree from the 
subtropical Himalayas with a short, straight trunk, spreading branches, 
and terminal clusters of fragrant yellowish flowers. It yields a yellow 
oleoresin with powerful adhesive qualities. The bitter, aromatic bark 
is used in India as a narcotic drug.

56826. PITTOSPORUM sp. From Yunnan, China. Collected by J. F. Rock, 
Agricultural Explorer. A shapely tree about 30 or 40 feet in height, 
with handsome foliage, and large terminal masses of cream-colored flowers followed by bright-red fruits.

55920. PLOCAMA PENDULA. From the Canary Islands. Collected by 
David Fairchild, Agricultural Explorer, A low-growing shrub, found 
on arid hillsides in the Canary Islands. It has a beautiful weeping 
habit, giving the plants the appearance of tiny weeping willows not 
over 3 feet high. It is able to withstand severe drought.

55939. POLYGALA ARILLATA. From Yunnan, China. Collected by J. 
F. Rock, Agricultural Explorer. A rare ornamental shrub 3 to 4 feet 
high, found on mountain slopes at an altitude of 7,000 feet. The 
bright-yellow flowers are borne in long spikes.

51877. POPULUS MAXIMOWICZII. Poplar. Presented by John Dunbar, 
assistant superintendent, Department of Parks, Rochester, N. Y. A very 
fast-growing and stately tree native to China. It will succeed in the 
coldest portions of the United States on the poorest and driest soils. 
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 
deciduous plant. The tree is not attacked by borers or leaf-eating insects; 
it is highly recommended as a shade tree and windbreak generally, 
especially for the northwest plains country.

48510. PORTULACARIA AFRA. Spek-boom. From Johannesburg, Transvaal, 
South Africa. A succulent South African shrub, rising to 12 feet, which 
affords locally the principal food for grazing elephants, but it is 
also well liked by sheep, and it should for this reason be tested in 
the southwestern United States on stony ridges and semiarid land, to 
which it is well adapted by reason of its cactuslike habit of storing 
water.
