Arthrophyllum

Arthrophyllum is a defunct genus of plants in the family Araliaceae. It was recognized by most authors until 2010, when all of its 30 species were "sunk" into Polyscias subgenus Arthrophyllum.

Arthrophyllum is mostly a genus of shrubs and small to medium trees, but it contains a few large trees, and in New Caledonia, a few lianas, as well. They are noted for their large and apparently leafy inflorescences, up to across. The fruit is 1-seeded and the ovary is unilocular. The genus is indigenous to Indomalesia and islands of the southwestern Pacific.
