''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.〔 David G. Frodin and Rafaël Govaerts. 2003. ''World Checklist and Bibliography of Araliaceae''. Royal Botanic Gardens, Kew. ISBN 978-1-84246-048-1. (See ''External links'' below). 〕 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.〔 Gregory M. Plunkett and Porter P. Lowry II. 2010. "Paraphyly and polyphyly in ''Polyscias'' sensu lato: molecular evidence and the case for recircumscribing the "pinnate genera" of Araliaceae". ''Plant Diversity and Evolution'' (formerly ''Botanische Jahrbucher'') 128(1-2):23-54. . 〕 In a companion paper, three of the species were "sunk" into synonymy with others, reducing the number of species to five.〔 Porter P. Lowry II and Gregory M. Plunkett. 2010. "Recircumscription of ''Polyscias'' (Araliaceae) to include six related genera, with a new infrageneric classification and a synopsis of species". ''Plant Diversity and Evolution'' (formerly ''Botanische Jahrbucher'') 128(1-2):55-84. . (See ''External links'' below). 〕 All species that were formerly in ''Reynoldsia'' are now in ''Polyscias'' subgenus Tetraplasandra, a subgenus of 21 species indigenous to Malesia and Pacific islands.〔 ''Reynoldsia'' was a genus of shrubs to medium-sized trees, mostly of dry habitats, especially the leeward sides of tropical pacific islands. The leaves are imparipinnate, and alternate. The leaf margin is never completely entire, but varies from obscurely to patently dentate. :es:William R. Philipson considered ''Reynoldsia'' to be hard to distinguish from ''Tetraplasandra'', another defunct genus to which it was closely related.〔William R. Philipson. 1970. "A redefinition of ''Gastonia'' and related genera (Araliaceae)". ''Blumea'' 18(2):497-505.〕 In general, ''Reynoldsia'' can be recognized by its toothed leaflets, greater number of ovary cells, and smaller number of stamens.〔 Porter P. Lowry II. 1990. "Araliaceae", pages 224-237. In: Warren L. Wagner, Derral R. Herbst, and Sy H. Sohmer. ''Manual of the Flowering Plants of Hawaii'', Revised Edition, 1999. Bishop Museum Press: Hololulu〕 ''Polyscias sandwicensis'' (formerly ''Reynoldsia sandwicensis'') is cultivated, albeit rarely, in Hawaii.〔 John L. Culliney and Bruce P. Koebele. 1999. ''A Native Hawaiian Garden''. University of Hawaii Press. ISBN 978-0-8248-2176-0. 〕 Instructions for its cultivation are available.〔 Kerin E. Lilleeng-Rosenberger. 2005.
