Cuphocarpus is an obsolete genus of flowering plants in the family Araliaceae.
 Mabberley (2008) treated it as a synonym of "Polyscias", but other authors still recognized it at that time.
 In 2010, in a phylogenetic analysis of DNA sequences, it was shown that "Cuphocarpus" was biphyletic and embedded in the large genus "Polyscias".
 In an accompanying paper, "Polyscias" was divided into 11 subgenera, with seven species left incertae sedis.
Gastonia is a formerly accepted genus of flowering 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".
Arctotis stoechadifolia, the African daisy or white arctotis, is a rare species of South African plants in the daisy family.
 It is a rare plant found only in sand dunes along the west coast of Cape Province.
Reynoldsia is an obsolete genus of flowering 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 Pacific islands.
Coscinocera hercules (Hercules moth) is a moth of the family Saturniidae, endemic to New Guinea and northern Australia.
 It has a wingspan of 27 cm , making it the largest moth found in Australia, and its wings have the largest documented surface area (300 square centimeters) of any living insect.
 The larvae feed on "Polyscias elegans", "Glochidion ferdinandi", "Dysoxylum muelleri", "Prunus serotina", "Timonius rumphii", but also eat other plants in captivity.
Arctotis venusta is a species of South African plants in the daisy family.
 Common names include silver arctotis, kusgousblom, and blue-eyed African daisy.
 It is native to the western coast of South Africa, The species is widely cultivated as an ornamental, and has become naturalized in parts of the United States (California, Arizona, South Carolina), Australia, and Central and South America, where it has escaped from gardens to become a noxious weed.
Polyscias elegans, known as the celery wood is a rainforest tree of eastern Australia.
 It occurs in a variety of different rainforest types, from fertile basaltic soils, to sand dunes and less fertile sedimentary soils.
 The range of natural distribution is from Jervis Bay (35° S) in southern New South Wales to Thursday Island (10° S), north of the Australian continent.
 Other common names include black pencil cedar and silver basswood.
 "Polyscias elegans" is useful to bush regenerators as a nursery tree, which provides shade for longer-lived young trees underneath.
 "Polyscias elegans" is also known as Celery wood, Mowbulan whitewood, Silver basswood and White sycamore.
Arthrophyllum is a defunct genus of flowering 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.
Arctotis is a genus of annual and perennial plants in the family Asteraceae.
Polyscias is a genus of flowering plants in the family Araliaceae.
 They bear pinnately compound leaves.
