Aehradelpha viridis (Plttier) 0. P. Cook. (Sapotaceae . ) 
43788. Seeds of injerto from Guatemala City, Guatemala. 
Collected by Mr. Wilson Popenoe, Agricultural Explor- 
er. "Fifty seeds from fruits purchased in the market 
of Guatemala City. The injerto is a common tree in 
this part of Guatemala. Unlike its near relative, 
the sapota (Lueuma mammosa) , which seems to thrive 
only at compartively low elevations in the tropics, 
the injerto is grown as high as 5000 or 6000 feet, 
and should, therefore, stand a better chance of suc- 
ceeding in California and Florida than the sapote, 
which has, so far, been a failure in those states. 
The tree grows to a height of about 40 feet in this 
region, and has long slender leaves suggesting those 
of the sapote. The fruits vary somewhat in shape, 
but are commonly * round to oval, often pointed at the^~~ 
tip. They are two to three and a half Inches in di- 
ameter, smooth, dull yellow-green In color, sometimes 
becoming almost dull yellow. The skin is not thick, 
and adheres closely to the flesh, which is red brown 
in color, soft and melting, sweet, with a pleasant 
flavor, somewhat resembling that of the sapote, but 
better. The large seed (sometimes there are two) is 
hard and polished, deep brown in color, and Is easily 
removed from the pulp." (Popenoe.)

jnany places in tropical Africa. The hairy pods are 
often sickle-shaped, with two or more joints. When 
in flower this tree is very ornamental. The wood Is

by the natives for making small boats and rafts. It 
might be commercially used for paper pulp. (Adapted
