          42730. PINUS BUNGEANA. The White-Barked Pine of China. Seeds 
collected by F. N. Meyer, at Peking, China. A very beautiful 
pine with silvery white bark; a slow grower with rather sparse 
foliage but extremely striking when old. The bark peels off 
in flakes like the bark of the sycamore but the white appearance 
becomes noticeable only when the tree is old. Occurs 
wild in China, but much planted around temples. The seeds 
are roasted and eaten by the Chinese. Hardy as far north as 
Boston.

21970. PISTACIA CHINENSIS. Chinese Pistache. From Shantung, 
China. A very promising shade tree for those sections of the 
United States where the summers are warm and the winters 
but moderately cold. The young leaves are carmine-red, and 
the fall foliage a gorgeous scarlet and yellow. The wood, 
which is very heavy and not often attacked by insects, is 
used in the manufacture of furniture. From the seeds an oil 
is obtained which is used for illuminating purposes. The 
young, partly opened foliage buds, boiled like spinach, are 
sometimes eaten by the Chinese.

12783. PISTACIA VERA. Pistache. From Sicily. Collected by 
T. H. Kearney, Agricultural Explorer. Var. Bronte. Named after 
the Duke de Bronte from whose Sicilian estate it came. The 
pistache is a small tree which is cultivated extensively 
in the Mediterranean region for its delicate-flavored, highly 
nutritious nuts called pistaches or pistachios. It is 
adapted to a dry warm climate. A variety with large nuts, purplish 
inner skin, and deep green kernel. As the tree is dioecious, 
arrangements for pollination must be made. Female buds 
on Chinese pistache stocks.

17250. PISTACIA VERA. Pistache. Var. Large Red Aleppo. Introduced 
by Rev. A. Fuller of Saratoga, Calif., from Aintab, 
Turkey. One of the commercial varieties in Turkey, producing 
large nuts of excellent quality and appearance.

50667. PLOCOSPERMA SP. From Guatemala City. Collected by 
Wilson Popenoe, Agricultural Explorer. An ornamental shrub 
with small, opposite, ovate leaves, which produces small purple 
flowers. Native name "Barreto."

50668. PLUMERIA ACUTIFOLIA. From Guatemala City. Collected 
by Wilson Popenoe, Agricultural Explorer. A stiff, erect, 
small tree up to 25 feet in height, known in English as 
"Frangipani"; it is a source of the perfume of the same name. 
The branches are naked except for clusters of leaves at the 
tip, where also appear in late spring the deliciously fragrant, 
white, star-shaped flowers. Native name "Palo de la 
Cruz." Very susceptible to frost.
