Polyscias cissodendron, commonly known as the Island Pine, is a species of tree in the ivy family, Araliaceae. It is native to New Caledonia and Vanuatu in Melanesia, as well as to Australia’s subtropical Lord Howe Island in the Tasman Sea. The specific epithet is derived from the Greek kissos (“ivy”) and dendron (“tree”). On Lord Howe it occurs in sheltered lowland forest.
