About

Cordia subcordata is a species of flowering tree in the family Cordiaceae. It can be found growing in eastern Africa, South Asia, Southeast Asia, northern Australia and the Pacific Islands. The plant is known by a variety of names, including kou, beach cordia, sea trumpet, and kerosene wood.

Where it grows

C. subcordata has a very wide range from the east coast of Africa east throughout tropical Asia and Oceania, as far as Hawaii. This distribution arose from the special characteristics of its fruit, which allowed successful oceanic dispersal. Prior to 2001, C. subcordata was considered to be a Polynesian introduction to Hawaii by many authorities, but subfossil evidence from Makauwahi Cave in Kauai indicates that it was an abundant species in Hawaiian lowland forests well before humans arrived, confirming its status as an indigenous species.

Uses

The seeds are edible and have been eaten during famine.
