MORACEAE, 
The family Moraceae consists of 55 genera which have a distribution similar 
to the Urticaceae ; though the number of species of the former is larger in tropical 
America. The family is closest related to Ulmaceae, but can be distinguished 
from them very easily by their inflorescence. It is less allied to the Urticaceae. 
The family Moraceae is an exceedingly useful one, primarily in their latex, 
which contains rubber in many species; second, in their fruits, which have a very 
pleasant taste, as figs, breadfruit, ete.; and, third, in the fiber, which is used for 
various purposes. 
The family is represented in the Hawaiian Islands by two genera, with two 
widely-spread species.

The Aiai is a milky tree or shrub, reaching a height of sometimes 40 feet. It 
is clothed in a whitish gray bark and has a trunk of up to 2 feet in diameter. 
The leaf resembles somewhat the mulberry at first appearance. 
The Aiai is not endemic to Hawaii, but is also found on Norfolk Island wal 
in Australia. In the Hawaiian Islands it may be found on Lanai in the gulches 
of the main range of Haalelepakai, at an elevation of 2300 feet. It is common 
on the island of Maui, especially in the dry gulches above Makawao, where the
