“…By contrast, the Southern Hemisphere has received much less attention. In the case of the South American diploid P. esculentum ( P. e. arachnoideum ), most of the research has focused on its ecology (e.g., Alonso‐Amelot and Rodulfo‐Baechler, 1996; Hartig and Beck, 2003; Portela et al, 2009; Silva Matos et al, 2012), phytochemicals, and phytotoxins (e.g., Rosero Negrete, 2013; Furlan et al, 2014) or is related to the behavior of the species as a weed (e.g., Dorantes, 2014; Guerin and Durigan, 2015; Xavier et al, 2023). The taxon is characterized by petiole bases with adventive roots, large fronds usually ~2 m long (sometimes reaching 4.5 m long), free lobes between the distal segments (or only decurrent lobes), simple distal segments <5 cm long, and a complex laminar indument composed of two or three kinds of hairs, abaxially on the segments: catenate hairs on costae and costules, arachnoid or acicular hairs on veins, and gnarled hairs on the laminar tissue between the veins, giving it a farinaceous appearance (Thomson and Martin, 1996; Thomson and Alonso‐Amelot, 2002; Schwartsburd et al, 2018).…”
