Typification of the Linnaean name Arum peregrinum (Araceae)

The typification of the Linnaean name Arum peregrinum , validly published in the first edition of Species plantarum , is discussed. In the absence of original material useful for lectotypification, a study of the various pre‐Linnaean works linked to this name, as well as an in‐depth analysis of literature, was necessary to understand its concept and designate a neotype. Tabula XXXVI in Plumier's Plantarum Americanarum , which was cited by Linnaeus in the tenth edition of Systema naturae under Arum peregrinum , is selected as neotype. Based on the typification, Arum peregrinum is synonymized with Alocasia macrorrhizos .
