Guatemalan type. —This group was first called to the attention of 
horticulturists by Collins in 1905. 1 Within the last few years it has 
been extensively planted in California and is now becoming known in 
Florida. It is found commonly in th'e mountainous parts of Guatemala 
and northward into southern Mexico, whence have come many of the 
cultivated varieties now being propagated in the United States. It 
was introduced to Hawaii about 20 years ago, according to Higgins, 
Hunn, and Holt, 2 while it appears to have been first planted in California 
about 1885. In Florida it was probably not introduced earlier than 
1900. It has not been observed in the West Indies,, with the exception 
of a few trees recently planted, and its distribution in other countries 
is quite limited. 
In California, where it is best known horticulturally, it has been 
found considerably hardier than the West Indian type, but somewhat 
more tender, as a rule, than the Mexican.
