with the avocado. The first step, certainly, is to 
secure the best available varieties and I feel sure that 
the Verapaz is one of them, for a thorough search 
through the territory in which the coyo is abundant, 
has disclosed none better. Its pear-shaped fruits 
weigh about a pound, and have a thick, leathery skin, 
and ivory-white flesh which contains much oil and has a 
rich, cocoanutlike flavor; the seed is about the same 
size as that of our best avocados. 
"The coyo probably does not come into bearing as 
young as the avocado, and as a rule it is not so pro- 
ductive in old age; but varieties which will be satis- 
factory in this latter respect can probably' be ob- 
tained. I am inclined to believe also that the fruit 
from young trees may be much inferior in quality to 
that from old ones. These points and several others 
must be determined by a trial in the United States and 
elsewhere. Since the tree occurs in Guatemala at al- 
titudes ranging from 300 to 6,000 feet, it seems prob- 
able that the species will succeed in cool regions 
like Southern California and South Florida as well as 
in warm ones like Cuba and Porto Rico." (Popenoe,) 
Persea sehiedcana (Lauraceae) , 49330. Hempstead Coyo. 
Prom Coban, Alta Verapaz, Guatemala. Cuttings col- 
lected by Mr. Wilson Popenoe, agricultural explorer. 
"No. 241. This variety has been called to my attention 
by Robert W. Hempstead, after whom I suggest It be 
named; the parent tree is growing in a small flnca 
along the road from Coban to San Cristobal Verapaz, 
and the fruit, which I have not seen, is described as 
large and of excellent quality. It is said to be pear 
shaped, somewhat slender, up to two pounds in weight, 
with ivory-white flesh free from fiber and of excel- 
lent quality in every way. The parent tree is prob- 
ably 50 years old, if not more; it is about 50 feet 
high, and is said to be productive; at the time this 
budwood was cut (Dec. 26) it was in flower. The sea- 
son of ripening is August and September. 
"In this variety and the previus one (Verapaz) 
we probably have two coyos of as good quality as can now 
be obtained, and with them as a beginning I believe 
it will readily be possible to develop from this spe- 
cies a fruit new to horticulture and of great value 
for tropical and subtropical regions." (Popenoe.)
