CASTANEA MOLLISSIMA. Chinese chestnut.  From North
China.  Collected by F. N. Meyer from old trees in a region where
the chestnut bark disease has probably existed for centuries.  High
degree of resistance, but entire immunity not probable.  Hardy tree,
not valuable for timber, being only 40 feet tall and low branching.
Nuts larger than American, but not so sweet. (PI. III.)

CASTANEA PUMILA x CRENATA. Hybrid chestnut. A
hybrid between the American chinkapin and the Japanese chestnut.
Produced by Dr. Walter Van Fleet, Chico, Cal.  Good producer and
strongly resistant to the chestnut bark disease.  Nuts of fair quality,
intermediate in size between the chinkapin and Japanese chestnut.

40035. CASTANEA sp. Chestnut.  From F. N. Meyer, Huihsien, 
Kansu, China.  A species of medium tall growth; trunk more
slender, and bark smoother than in C. mollissima, also the leaves,
burs, and nuts are smaller.  Prefers well-shaded situations, and damp
soil.  Of value as a nut-bearing tree.

37900. CELTIS sp.  A tree about 30 feet high and sometimes
spreading in habit, related to our native hackberry, found growing
on the river banks in Pirapora, Minas Geraes, Brazil.  The small,
orange-colored fruits, about one-fourth of an inch in diameter, are
edible and eagerly sought after by boys.

CERATONIA SILIQUA. Carob. Evergreen tree, 20 feet high,
with thick trunk and shining leathery leaves.  The female trees
produce dark-brown pods, about 4 to 10 inches in length, commonly
known as St.-John's-bread; these are eaten for their sweetish pulp.
They also form a very nutritious feed for cattle.

CHAENOMELES CATHAYENSIS. From F. N. Meyer, China.
A shrub or small tree, the fruits of which are prized for their strong,
pleasant aroma.  Used in China for perfuming rooms; also for 
preserves.  Leaves turn rich scarlet in the fall.  Probably not hardy
north of Philadelphia, except in sheltered locations.  Known also as
Cydonia cathayensis.

40550. CHAETOSPERMUM GLUTINOSIIM.  From William
S. Lyon, Manila, Philippine Islands.  A Philippine tree allied to
Citrus, and recommended for trial in semiarid regions as a stock for
the cultivated citrus fruits.  Occurs on gravelly hillsides almost
devoid of rainfall during seven months of the year.  It is probably
susceptible to frost.
