Phylogenetic studies have shown that Schefflera, the largest genus of Araliaceae, is highly polyphyletic, comprising five non-sister clades within the family, and that the generic name must be restricted to a small group of Pacific Island species. In an effort to establish monophyletic genera for the other elements still remaining in Schefflera, phylogenetic analyses of the large Neotropical clade have revealed five morphologically and geographically coherent groups. Here, we reinstate the genus Sciodaphyllum, which corresponds to the largest of these five groups, presenting a synopsis of the 131 currently recognized species, including 109 new combinations, one replacement name (nomen novum), and three new heterotypic synonyms. The re-establishment of Sciodaphyllum opens the way for describing an estimated 200+ new species in the genus, nearly all of which are from the Northern and Central Andes.

新热带五加科研究。I. Sciodaphyllum P. Browne 属的复活，以适应先前包括在 Schefflera JR Forst 中的大多数新世界物种。& G. 福斯特。

系统发育研究表明，鹅掌楸是五加科最大的属，具有高度的多系性，包括该家族内的五个非姐妹进化枝，并且该属名必须仅限于一小群太平洋岛屿物种。为了为仍保留在鹅掌楸中的其他元素建立单系属，对新热带大进化枝的系统发育分析揭示了五个形态和地理上一致的群体。在这里，我们恢复了 Sciodaphyllum 属，它对应于这五个组中最大的一个，提供了 131 个当前公认的物种的概要，包括 109 个新组合、一个替换名称 (nomen novum) 和三个新的异型同义词。Sciodaphyllum 的重建为描述该属中估计 200 多个新物种开辟了道路，
