          tubers. During the year 1916, 660,000 pounds of this starch were produced  
from about 3,000 tons of tubers. In the Andes of South America 
the tubers are eaten by the Indians in much the same way as the potato 
is used in the United States. The plant lends itself to cultivation 
as an annual in the southern United States, young tubers being 
planted in the spring, and the crop harvested in the fall. Rich soil 
and abundant moisture are favorable to the successful culture of this 
species.

54043. CARISSA CARANDAS. From Poona, Bombay, India. A large, 
spiny, ornamental, evergreen shrub with elliptic, leathery, shining 
leaves and clusters of white, funnel-shaped flowers half an inch long, 
followed by purplish black, edible fruits which may be eaten either 
from the tree or made into excellent jelly, pickles, and preserves. 
The plant does well in certain parts of southern Florida and southern 
California.

54530. CARYOPHYLLUS MALACCENSIS. Ohia or Malay-apple. From 
Panama. Seeds collected by Dr. David Fairchild, Agricultural Explorer. 
This handsome tree, native to tropical Asia and a relative of the 
clove, deserves much wider cultivation in tropical America than it 
enjoys at present. It makes an erect, slender, pyramidal tree with 
large, dark-green, shining leaves, and produces in great abundance 
large, rose-red flowers, whose showiness is due to a long cluster of 
stamens. Most of these flowers are produced on the larger branches 
and are only visible when one is standing directly under the tree, at 
which time they appear to form a fairy haze of enchanting loveliness. 
The fruit is not of great value, but is used for preserves in the Asiatic 
tropics; it is sometimes 2 inches long, white to rose colored, 
with crisp, acidulous flesh, and 1 or 2 large seeds loose in a hollow 
cavity. It is suitable for cultivation only in lower Florida and tropical 
America.

54923. CASSIA NODOSA. Pink-and-white Shower. From Hawaii, Seeds 
presented by Dr. H. L. Lyon. This magnificent flowering tree is much 
used for street and ornamental planting in Honolulu, and elsewhere in 
the Tropics. It is a moderate-sized, deciduous tree with long drooping 
branches and glossy leaves. During May and June it bears a profusion 
of beautiful, bright pink and white, rose-scented flowers in 
dense clusters. This tree is native in India and the Philippines; in 
this country it would succeed only in extreme southern Florida, in 
Cuba, or others of the West Indian Group.

54463. CASSIA SIAMEA. From Honolulu, Hawaii. Seeds presented by 
Dr. H. L, Lyon. A medium-sized or large tree with grayish bark, 
graceful pinnate leaves, and large clusters of small, yellow flowers. 
The tree is valued as an ornamental and for its hard, heavy, durable 
timber, which is used for mallets, tool handles, walking sticks, for 
building purposes, and for fuel.
