Abstract
Sciodaphyllum zarucchii M. M. Mora, Lowry, Idárraga, Jiménez-Mont. & G. M. Plunkett (Araliaceae) is described as a new species in honor of James L. Zarucchi (1952–2019). It occurs in humid premontane and montane forests on the western slope of the Cordillera Occidental in the department of Antioquia, Colombia, where it is known from only two localities, one of which is highly threatened by forest clearing. A risk of extinction assessment using the IUCN Red List criteria reveals that S. zarucchii is Endangered.

Etymology. This tree is named in honor of James L. Zarucchi (1952–2019), who joined the staff of the Missouri Botanical Garden in 1983. Both in the course of his doctoral studies at Harvard University (Ph.D.,1982) and for his first 13 years at the Garden, Jim concentrated on Latin American plants. He notably collected and encouraged studies of the flora of the Andes, especially in the departments of Antioquia and Vaupes, Colombia, coincidentally describing the genus Quiotania Zarucchi (Apocynaceae), its name an anagram for that of the Colombian Department of Antioquia. In 1996, Jim was named Managing Editor of the Flora of North America project, making an extensive contribution of great importance in that role for the remaining 23 years of his life (Ulloa et al., 2019).
