Zanthoxylum dipetalum is a rare species of tree in the family Rutaceae and in the same genus as Sichuan pepper. It is known by the Hawaiian names Kāwa'u and Heaʻe and is endemic to the Hawaiian archipelago, where it grows in forests on 3 or 4 of the islands.[2]

There are two varieties.[2]

The roots of Z. dipetalum have been found to contain several chemical compounds, including canthin-6-one, chelerythrine, nitidine, tembetarine, avicennol, xanthoxyletin, lupeol, hesperidin, sitosterol, and magnoflorine.[5]
