along the bank of a small stream. It seems, however, 
to be comparatively rare, and does not occur in great 
numbers. It is erect and slender in habit, growing 
to a height of 40 or more feet, with foliage somewhat 
finer than J. nigra of the United States. The nuts re- 
semble those of J. nigra in size and appearance, though 
sometimes smaller. The kernels, however, are removed 
with difficulty, the septae being very thick and woody. 
In its present wild state the Cuban walnut, as it is 
called, does not seem of great horticultural value, 
but with very little improvement by selection it seems 
that it might become an excellent nut for tropical 
regions. It has been suggested that it might serve as 
a stock for the Persian walnut, making possible the 
culture of this species in Cuba and other tropical 
regions where it is not now successfully grown. For 
illustrations of the tree and fruit see Journal of 
Heredity, December, 1915." (Wilson Popenoe.) 
Litchi ehinensis Sonne rat . (Saplndaceae .) 43034. Seeds 
from Swatow, China. Presented by Mr. G. C. Hanson, 
American Consul. "This fruit is placed on the market 
at the beginning of summer, and can only be obtained 
during a very short period. The Swatow litchi has the 
reputation of not being as good as the Canton variety, 
which also matures early in the summer. Grown in the 
neighborhood of Chaochowfu. " (Hanson.) 
Osterdamia matrella (L.) Kuntze. (Poaceae.) 43023. 
Seed from Yokohama, Japan. Purchased from the Yokohama 
Nursery Company. A creeping grass, important for 
binding coast-sands, which does well on alkali soils, 
and also as a lawn-grass. Said to be relished by stock. 
Paeonia brownii x albiflora, (Ranunculaceae . ) 43015 . Seeds 
from Los Angeles, Calif. Presented by Mr. P. D. Barn- 
hart. "From our native paeonia which are the products 
of flowers that I pollinated with pollen of the Chinese 
type, such as you grow in the East. I got the material 
of the Henry A. Dreer people last year. They collect- 
ed It from white varieties in their great field. I 
hope to get a cross that will bear large flowers, and 
plants that are adapted to this climate. Our hills 
are covered with them, but the flowers are small and 
inconspicuous, though they begin to bloom, and pro- 
fusely too, in early February and continue into March. 
This year the first flowers appeared in January, and 
those that I worked failed to set seed. I used heavy 
paper sacks to protect the subjects from rain and in- 
sects." (Barnhart.)
