a Most of the fruits represented in this table were collected about Honolulu at low elevations; the cofTee, 

 however, was collected on the island of Hawaii, in addition to localities in Honolulu, and much of it came 

 from points 1,000 to 2,000 feet above sea level. 



b The June collection of coffee came from the Waianae Mountains, where only Opius humilis was 

 established.
