          The tubers are small and numerous and look like a lot of closely 
strung beads. The plant is hardy and is propagated by the tubers. 
These are set out in rows in a rich loamy clay soil very early in 
spring, about potato-planting time. They are covered to the depth 
of 6 or 8 inches in hills 16 inches apart. The ground should not be 
stirred after the first of October, so as not to disturb the forming 
tubers which may he dug in November and should he stored in dry soil 
at a uniform temperature with protection from the air to prevent discoloration.

53918. STEVIA REBAUDIANA. From Paraguay. Presented by the Botanic 
Gardens, Asuncion, through D. S. Bullock, agricultural trade commissioner. 
A small shrub, with slender stems and inconspicuous white 
flowers, of little ornamental value, but interesting because it contains 
a sweet glucosid. When placed in the mouth and chewed, a single 
leaf is so sweet as almost to be unpleasant. As a possible substitute 
for sugar in the dietary of persons suffering from diabetes the species 
has attractive possibilities.

56018. STYRAX LANGKONGENSIS. From Yunnan, China. Collected by 
J. F. Rock, Agricultural Explorer. An ornamental shrub 1 to 2 feet 
tall which grows in the arid region between Langchiung and Shapi at an 
altitude of 7,500. feet. The flowers are large, white, and drooping, 
with rich reddish brown calyces. It may prove of value as an ornamental 
for the Southern States.

32072. SYZYGIUM CUMINI. Jambolan. Presented by Dr. L. Trabut, 
Algiers, Algeria. This handsome tree, a native of Asia, has long 
slender leaves somewhat resembling those of certain eucalypts. Its 
small black fruits, produced in clusters, are acidulous in flavor, suggesting 
sweet cherries. There is wide variation in the quality of 
fruit produced by different trees; that of some is large (an inch long), 
sweet, and pleasant, while that of others is smaller, and almost bitter. 
The tree is sufficiently hardy for cultivation in southern Florida and 
the milder parts of California.

56592. TACSONIA LANATA. From Bogota, Colombia. Presented by Brother 
Ariste Joseph, Institute de la Salle. An evergreen climber native 
to Colombia. All parts of the plant are covered with downy wool. The 
long, slender, salmon-pink flowers are borne singly and are quite ornamental. The fruit is said to be edible.

51567. TACSONIA MANICATA. From Colombia. Collected by Wilson Popenoe, Agricultural Explorer. In Bogota this is called Curuba de Indio, 
and it is one of several cultivated species of Tacsonia in the neighborhood. 
It is not, as a fruit, so good as the Curuba de Castilla,
since it has less highly flavored pulp, but as a vine it is more ornamental. 
The fruits are green, oblong, and about 3 inches in length. 
The tacsonias are closely related to the granadillas, (Passifiora spp.), 
and like them are adapted to cultivation only in the warmest portions 
of the United States.
