Sapindus oahuensis is a species of tree in the soapberry family, Sapindaceae. It is endemic to Hawaii, where it is limited to Kauaʻi (Waimea Canyon) and Oʻahu (Waiʻanae and Koʻolau Ranges).[4] Its common names include Āulu,[5] Oahu soapberry, alulu, kaulu, and lonomea.[2]

Fruits

It can be found in dry and moist forest habitat at elevations of 200 to 2000 feet.[4]

Āulu grows up to 18 m (59 ft) tall with a trunk diameter of 0.5 m (1.6 ft). It has alternately arranged, hairless leaves which have simple blades, unlike its congener, the wingless soapberry (S. saponaria), which has compound leaves. The leaves are somewhat thick and green with a yellow midvein. They are up to 15 centimeters long. The inflorescence is a panicle of many greenish yellow, bell-shaped male and female flowers. The fruit is a shiny, leathery berry roughly 2 centimeters long, containing one large black seed.[5]

The seeds were strung and used in leis.[5]
