Anredera cordifolia (Basellaceae) invasive in the river vegetation of North-Eastern Sicily

Abstract

Piccione, V. & Malacrinò, V.: Anredera cordifolia (Basellaceae) invasive in the river vegetation of North-Eastern Sicily. — Fl. Medit. 31 (Special Issue): 501-507. 2022. — ISSN: 1120-4052 printed, 2240-4538 online. The occurrence of Anredera cordifolia as invasive element of the vegetation of the watercourses of the Tyrrhenian East coast of Sicily is reported. The species indicated in Sicily as alien and then as a rapidly spreading plant in the Western sector of the island had already been reported for some generic localities in the province of Messina. Here it is reported its abundant presence, within hygrophilous forest phytocoenoses where the species ends up physiognomizing the woody vegetation of a stream. In this vegetation, A. cordifolia exerts an indisputable synecological role and, at the same time, has an impact that deserves to be monitored.
