42720. TOLUIFERA BALSAMUM. Tolu balsam tree.
From Mr. H. M. Curran, Calamar, Colombia. A South American
balsam-bearing tree, up to 75 feet or more in height. The foliage
resembles that of the locust, as do the white or whitish clusters of
pealike flowers. Trunk straight, covered with thick rough bark.
The balsam is obtained from incisions in the bark.

41871. TRACHYCARPUS TAKIL. Fan palm. From Mr. A.
C. Hartless, Seharunpur, India. A lofty Himalayan palm, 40 to 50
feet high, of slender and stately appearance. It much resembles the
somewhat smaller Chinese Windmill palm (T. excelsus), which has
been planted extensively in California. Found at altitudes up to
8,000 to 10,000 feet in the western Himalayas. Fruits are said to be
edible.

43580. TRICONDYLUS MYRICOIDES. From Mr. H. B.
Shaw, Clarence, Blue Mountain, New South Wales. Ornamental
shrub, 8 to 10 feet in height, with very narrow lanceolate leaves and
terminal or axillary clusters of cream-colored flowers. The wood,
which is of value, is very hard, light colored, and beautifully marked.

44415. TRICONDYLUS OBLIQUA. From the Jardin Botanico,
Buenos Aires, Argentina. Ornamental Chilean shrub with
alternate, smooth, slightly toothed leaves, and yellowish white
flowers in axillary racemes. It is not unlikely that the wood may
be of value in cabinetwork, as is that of other species of this genus.

32831. ULMUS DENSA. Charavidny elm. From F. N.
Meyer, Oasis of Merv, Russian Turkestan. Divides into several
stems immediately above the ground, forming a remarkably dense
umbrellalike head. Valuable shade tree for regions with long, hot
summers and winters not too cold. Thrives fairly well on alkaline
soils.

ULMUS FOLIACEA SUBEROSA. Cork-barked elm. Ornamental
tree of stiff, spreading, low habit, with corky winged
branches and smooth, bright-green obliquely oval leaves. The
corky ridges, of which there are usually four, do not appear until
the branches are two or more years old. Said to be common in the
forests of central Europe, where it is a native woodland tree.

ULMUS PUMILA. North Chinese elm. Shade and timber
tree, remarkably resistant to droughts, alkali, and severe extremes of
temperature. Timber used in China mainly in the manufacture of
carts. Of exceptional promise as a shade tree for the semiarid regions
of the United States, where it has made phenomenally rapid
growth. Deserves trial in shelter belts of the Northwest.
