About

Alphitonia ponderosa is a species of flowering tree in the family Rhamnaceae, that is endemic to the Hawaiian Islands. It is locally known as kauila, as is the related Colubrina oppositifolia.

Uses

The reddish-brown wood of A. ponderosa is highly prized for its beauty, strength, and density. It was used as a replacement for metal by the Native Hawaiians, who made laʻau melomelo (fishing lures), pāhoa (daggers), ihe (short spears), pololū (long spears), ʻōʻō (digging sticks), hohoa (round kapa, beaters) ʻiʻe kūkū (square kapa beaters), leiomano (shark tooth clubs), and kiʻi (tiki carvings) with it.
