islands beyond it. As far as I am aware, it had been previously gathered by Forster alone. In this group it attains a height of 30 feet, amongst other trees near the sea. Its trunks are sometimes 2–3 feet in diameter, covered with a smooth brown bark; the wood is white and close-grained. Branches much scarred, and clothed with a pale bark, very brittle. The distinct joint at the apex of the petiole indicates the truly compound nature of the leaves; they are nowhere described as ternate; a character which all young trees of this species exhibit. The whole plant has a faint but rank smell, like that of Ivy, which the copious lurid green but shining coriaceous leaves much resemble, both in hue and texture. The involucral leaves are very small and subulate.
