Psydrax odorata, known as alaheʻe in Hawaiian, is a species of flowering shrub or small tree in the coffee family, Rubiaceae.[3] It is native to the Pacific Islands, New Guinea and Australia.[1][4]

Description[edit]

The species range from 6–30 ft (1.8–9.1 m) in height, has a spread of 3–7 ft (0.91–2.13 m),[5] and a trunk width of up to 4 in (10 cm).[6] The leaves are glossy green in colour, are up to 3.5 inches (89 mm) long and elliptic. The fruits of the plant are quite round, are black in colour and 3/8 wide.[5]

Ecology[edit]

The fruits produce many seeds which are often attacked by the larvae of Orneodes objurgatella, a species of moth.[5]

Habitat[edit]

The species can be found growing in dry shrub land and in dry to moist forests at elevations of up to 2,700 feet (800 m).[5]

Uses[edit]

Native Hawaiians used the very hard wood of alaheʻe to make koʻi alaheʻe (adzes for cutting softer woods such as Erythrina sandwicensis), ʻōʻō (digging sticks), and ʻo (short spears). A black dye was made from the leaves.[4]
