The family Oleaceae, which consists of about 370 to 390 species, inhabits the 
temperate, subtropical and tropical regions of the earth, especially in East India, 
where some of the genera like Jasminum and others are rich in species. Only 
about 12 species belonging to this family occur in Europe; in Polynesia and Aus- 
tralia about 26; in America and Africa each about 46 species. In the Hawaiian 
Islands the family is represented by the genus Osmanthus with a single species.

The Pua or Olopua is one of the most common Hawaiian trees, but rarely in- 
habiting the rain forests or even their outskirts. It is more confined to the 
lower forest zone, especially on the leeward sides of all the islands, and is usually 
the predominating tree on the lava fields of Hawaii. The Pua, like all Hawaiian 
trees, is very variable and only a trained eye can at first glance decide if it 
is the Pua or not. The leaves are often very large and again very small, as in 
the Molokai specimens, which have elliptical lanceolate leaves, while those of
