ficient length of time to demonstrate satisfactorily 
their commercial worth and adaptability , and therefore 
are not yet recommended by this Department for com- 
mercial cultivation. The purpose of this release , which 
is made at the request of the California Avocado As- 
sociation and numerous individual growers, is to fa- 
cilitate the distribution of the varieties and make 
possible wider and more effective trial than has yet 
been given them. 
All of these varieties are described in Depart- 
ment Bulletin 743, "The Avocado in Guatemala," where 
also are published the names which have been given 
them. The Department desires that all of the varieties 
be propagated and disseminated under the names therein 
published, and will appreciate your cooperation to 
this effect. 
The variety Itzamna was not distributed along 
with the others of the collection. At Miami, Florida, 
it has fruited for several seasons, and has proved 
to be later in ripening than most other Guatemalan 
sorts. Budwood of this variety can be supplied to those 
who desire to test it.
