          the preceding variety (No. 37943) by the reddish maroon color at each 
end of the petiole or leaf stalk.

46801. DIOSCCREA ALATA. Greater Yam. A West Indian variety of 
yam grown for several years near Miami, Fla. The tubers, which are 
white fleshed and drier than those of most varieties, are of good flavor 
though often rough and irregular in shape. Tubers sometimes reach 
a weight of 15 pounds in rich sandy loam or on well-drained muck 
soils.

52575. DURANTA TRIACANTHA. From Ambato, Ecuador. Seeds collected 
by Wilson Popence, Agricultural Explorer. An indigenous shrab common 
in ravines and on hillsides about Ambato. It grows to a height of 
15 feet and is heavily armed with stiff, sharp spines. The pretty 
blue flowers, about half an inch broad, are borne in great profusion 
in racemes at the ends of the branches, and are followed by golden 
yellow berries, which suggest currants in appearance. Its relative, 
D. plumieri, which has smaller flowers and taller stature, has already 
proved successful in Florida. For trial as a hedge plant in California 
and Florida.

51017. ELAEIS GUINEENSIS. Oil Palm. From Buitenzorg, Java. Seeds 
presented by Dr. P. J. S. Cramer, director, Plant Breeding Station. 
A graceful palm, widely distributed throughout the Tropics, with a 
stout, deeply ringed trunk 20 to 30 feet high, crowned by large pinnate 
leaves with prickly leaf stalks. The bright-red fruits are used 
for food; an intoxicating drink is prepared from the juice of the 
stem; and the leaf stalks and leaves are used for thatching native 
houses. The most important product, however, is obtained from the 
fleshy outer layer of the fruits and from the kernels. The fleshy 
covering yields the ordinary palm oil used in the manufacture of soap 
and candles, while the kernels yield a white, or nut oil, employed in 
the manufacture of margarine, or artificial butter.

52437. ELAEOCARFUS SIAMENSIS. From Bangkok, Siam. Seeds collected 
by J. F. Rock, Agricultural Explorer. A handsome tree growing to a 
height of about 30 feet. The leaves are lanceolate, papery, 3 to 4 
inches long; the white flowers, which occur in racemes, are followed 
by an abundance of seeds used by the natives as a narcotic. Recommended 
for trial as an ornamental in southern Florida.

54897. ERYTHRINA MONOSPERMA. From Honolulu, Hawaii. Seeds presented 
by Dr. H. L. Lyon. A tree 20 to 30 feet in height with spreading 
crown of stiff, gnarled branches, and clusters of brick-red, 
orange, or pale yellow flowers. The pods contain scarlet or dark-red 
seeds. The wood, which is soft and very light, was formerly used by 
the Hawaiians as floats on the outriggers of their dugout canoes. The 
tree is found in dry regions throughout the Hawaiian Islands, it is 
introduced for trial in California, Florida, and our tropical dependencies.
