strom.) Passiflora sp. 42033. "A Passiflora much cultivated 
by the Indians in the valley of Zambiza, north-east of 
Quito. The fruit is smaller than No. 42032, is sweeter, 
and contains more seed. The flower is much attacked by 
bats and mice so that at Quito the plant seldom has 
fruits; it also requires a warmer climate, 17 to 18 degrees 
C. The Zambiza valley is about 1,000 to 1,500 feet lower 
than Quito and much warmer. Collected during the months of 
September to October." (Soderstrom.) Passiflora ligularis 
Juss. 42035. "The Granadilla or passion flower plant. This 
plant is cultivated in all the warm valleys in the interior 
of Ecuador. I have even found this plant growing wild in 
the woods at about 6 r 000 feet altitude. In the woods the 
squirrels always eat the fruit so very few seeds can be 
collected there." (Soderstrom.) 
Pinus bungeana Zucc. (Plnaceae.) 41954. Seeds of the 
white-barked pine of North China. Collected by Mr. D. P. 
Higgins, Peking. "These seeds are from trees about 12 miles 
west of Peking." (Higgins.) Although the oldest specimens 
of this most remarkable pine have not yet shown their white 
barked character In America, they are situated In moist 
regions and it may require a drier climate to develop this 
attractive characteristic which makes this one of the most 
striking of landscape trees. (Palrchlld.) 
Piratinera alicastrum (Sw.) Baillon. (Moraceae.) 41880. 
Seed6 from Merlda, Yucatan, Mexico. Presented by Dr. L. 
Lavedan, New Orleans, Louisiana. "The leaves are used ex- ; 
tenstvely for forage purposes in Yucatan, as already re- 
ported by Mr. G. N. Collins of this office a few years ago. 
Dr. Lavedan also considers that the seeds, which are pro- 
duced in great abundance, might be utilized as a source of 
industrial starch, or perhaps distilled Into alcohol. I 
have assured him that we would be Interested to test the 
possibilities of growing this tree, at. least in southern 
Florida." (O. P. Cook.) 
Primus serrulata Llndley. ( Amygdalaceae . ) 41817 to 
41870. A collection of scions of 54 named varlties of 
Japanese flowering cherries, presented by the Municipality 
of Tokyo to the American Government. These scions were cut 
from authentic trees growing in the famous Arakawa flower- 
ing cherry collection maintained by the Tokyo Municipality, 
which collection contains, in the opinion of such a noted 
authority on the subject as Mr. Funatzu, some of the love- 
liest forms of these remarkable trees. This collection 
duplicates one which was secured by Mr. E. H. Wilson of 
the Arnold Arboretum in January, 1915, (see S.P.I. Nos. 
39743 to 39798 and 39820 to 39826), many numbers of' which 
we were not successful In propagating. The arrangements to
