          reaches a height of about 12 feet. For trial in subtropical regions 
of the United States.

55509. PERSEA AMERICANA. Collinson Avocado. A seedling of the 
Collins avocado, originated at the Plant Introduction Garden, Miami, 
Florida. It is generally considered to he a hybrid, the seed-parent 
(Collins) being a Guatemalan, and the pollen-parent an unknown West Indian variety. Because of its vigorous growth, free-bearing habit, and 
good quality of fruit, it is looked upon as commercially promising, and 
is being planted extensively in Florida orchards. The fruit, which 
matures at Miami in January, is broadly oval to round, 16 to 24 ounces 
in weight, glossy green, smooth-skinned, and very attractive in appearance. 
The seed is rather large, tight in the cavity, and the yellow 
flesh which is devoid of fiber markings, is rich and nutty in flavor. 
The tree is a much stronger grower than most of the Guatemalan 
varieties, and promises to fruit more regularly.

55736. PERSEA AMERICANA. Itzamna Avocado. Budwood sent from 
Guatemala by Wilson Popenoe, Agricultural Explorer. This is the best 
late-ripening Guatemalan avocado yet tested at the Plant Introduction 
Garden, Miami, Florida. The tree is a strong grower, shapely, with 
stiff branches. Up to the present it has borne regularly, its behavior 
in this regard being much more satisfactory than that of many other 
Guatemalan varieties. The fruit, which matures at Miami from March to 
early May, is slender pyriform, 14 to 18 ounces in weight, dark green 
and somewhat rough on the surface. The flesh is deep yellow, free 
from discoloration or fiber, smooth, very dry, and of rich, nutty 
flavor. The seed is medium-sized and tight in the cavity.

54767. PHOENIX OUSELEYANA. From Calcutta, India. Presented by 
Percy Lancaster, secretary, Agricultural and Horticultural Society of 
India. An armed palm with a stem 9 inches thick, reaching only 12 feet 
in height. The fruits are orange-colored until fully ripe; when they 
turn black they are edible. Native to the southern slopes of the 
Himalayas.

55611. PHOENIX sp. From Nice, France. Presented by Dr. A. Robertson Proschowsky. This and the following numbers from Dr. Proschowsky 
represent hybrids which have originated on the Riviera, the parents 
being several species of Phoenix which are cultivated as ornamental 
plants in that region. They are worthy of trial in those portions of 
the United States where the temperature does not go below 20° F.
