ornamental shrub 4 feet high, found growing on limestone rocks. The 
flowers are white with a pinkish tinge, and the fruits are black." 
vitis sp. ( Vitaceae ) , 55953. Grape. From Yunnan, China. Seeds 
collected by J. F. Rock, Agricultural Explorer of the Bureau of Plant 
Industry. "(No. 6286. September ?, 1922. ) A very hardy wild grape 
found covering rose bushes along streams among limestone bowlders in 
the northern end of the Likiang snow range at an altitude of 10,000 
feet. The leaves are small, thick, and deeply 3-lobed. The vine is 
a prolific bearer. The small, dull purple fruits, a little larger 
than pea#s, with large seeds, are borne in racemes 3 to 4 inches long, 
and are very sweet, with no acid taste." (Rock.) 
warszewiczia coccinea (Rubiaceae), 56022. From Camboa, Canal 
Zone. Seeds presented by F. Marti. "This is a remarkable ornamental 
t tree; I first saw it on the banks of Gatun Lake at Rio Sucio. At a 
distance its racemes - over 2 feet long -with their brilliant scarlet, 
enlarged sepals produced a startling splash of color against the dark- 
green foliage. The color is as vividly scarlet as the autumn colors 
of the sour gum, the sorrel tree, or some species of Japanese maple. 
The colored 'leaves' are in reality enlarged sepals. Only one flower 
in each cluster of flowers on the raceme has an enlarged sepal. Though 
the flowers themselves are not over a quarter of an inch in diameter, 
the enlarged sepals are often Z\ inches long. The fact that this 
tree blooms in summer - the wet season - whereas most of the showy 
flowering trees of the Tropics bloom in the dry season, would seem to 
make this an unusually valuable ornamental tree for tropical regions. 
It is certainly worthy of a place in every collection of tropical 
trees." (David Fair child. )

amygdalus persica ( Amygdalaceae ) , 43134. Peach. "Osprey Im- 
proved." From Avondale, New Zealand. "This is a fair grower and an 
unusually precocious bearer. It has borne about 25 medium-sized, light- 
colored, very sweet, freestone peaches of good flavor. It is excellent 
for home use but will not ship." (Dr. Alfred Shryock, Loma Linda, 
Calif., December, 1922.) 
casuarina cunninghamiana ( Casuar inaceae ) , 49720. Beefwood. Origi- 
nally from Australia. "This was planted in 1922. It is now a very 
beautiful tree and outgrows everything else on the place." ( C. J. 
West, Lake Childs, Fla., December 16, 1922.) 
CUCUMIS SATIVUS (Cucurbitaceae) , 40783. Cucumber. From Seharunpur,
