GastoniaCommerson ex Lamarck is a formerly accepted genus of plants in the ivy and ginseng family, Araliaceae. It had been known as an unnatural group, but was recognized as late as 2010, when its nine species were distributed to four different subgenera of the large genus Polyscias. Because the genus Gastonia is now obsolete, its species are herein referred to by their names in Polyscias.
Schefflera is a genus of flowering plants in the family Araliaceae with 13 species native to New Zealand and some Pacific islands.
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.
Polyscias is a genus of flowering plants in the family Araliaceae. They bear pinnately compound leaves.
Delarbrea balansae is a species of flowering plant of family Myodocarpaceae. It is endemic to New Caledonia. It has previously been classified as the sole member of genus Pseudosciadium, but molecular and morphological studies point to its inclusion in the genus Delarbrea.
Reynoldsia is a formerly recognised genus of plants in the ivy family, Araliaceae. In 2003, Kew Gardens published a checklist for Araliaceae, in which eight species were recognized for Reynoldsia: four from Samoa, two from Tahiti, one from the Marquesas, and one from Hawaii. In 2010, a phylogenetic comparison of DNA data showed that Reynoldsia was polyphyletic, consisting of two groups that are not each other's closest relatives. In a companion paper, three of the species were "sunk" into synonymy with others, reducing the number of species to five. All species that were formerly in Reynoldsia are now in Polyscias subgenus Tetraplasandra, a subgenus of 21 species indigenous to Malesia and the Pacific islands.
Astropanax is a genus of flowering plants in the family Araliaceae, native to Tropical Africa, Madagascar, and other Indian Ocean islands. It was resurrected from Schefflera in 2017.
