<p><strong>Going unnoticed for 40 years: about the presence of the exotic <em>Suaeda paradoxa</em> (Chenopodiaceae, Suaedoideae) in Argentina</strong></p>

Abstract

As a part of ecologic studies conducted in wetlands of Patagonia, Argentina, and in the frame of taxonomic studies within Chenopodiaceae for South America, we collected specimens of Suaeda that did not match the features to any of the species currently known to the Flora of Argentina. The aim of this contribution is to report for the first time the presence of Suaeda paradoxa in Argentina, by the means of the study of living plants and herbarium material, original descriptions, type material, and complementing with a distribution map, photos, a diagnostic key, and a comparative table to the herbaceous species of Suaeda in Argentina. Also, some comments regarding ecological and distributional features are discussed. This is the first record of S. paradoxa outside its native distribution range.

Three new alien Chenopodiaceae species in the flora of Russia

“…originated from different regions of Eurasia and have been reported as alien in Australia (Wilson, 1984). A large number of Eurasian Chenopodiaceae with further naturalization were discovered in temperate South and North America (e. g., Aellen, 1929;Zappettini, 1953;Clemants, Mosyakin, 2003;Brignone et al, 2016;Jocou et al, 2020;Brignone, Denham, 2021). Similarly, many Australian and American Chenopodiaceae, especially different Chenopodium taxa (recently considered within the genera Chenopodium s.…”

“…Dysphania pumilio occurs as a native species mostly in southern Australia (Wilson, 1984) with further spreading as an alien into many subtropical regions of southern, central and eastern Africa (Brenan, 1954;Germishuizen, Meyer, 2003;Sukhorukov et al, 2016), Japan (Flora-Kanagawa Association, 2018, North and South America (Gleason, 1952 as Chenopodium pumilio;Clemants, Mosyakin, 2003;Funez et al 2017;Brignone, 2020). At present, it is considered to be an invasive plant in North America (CABI, 2021).…”

The genus Sesuvium (Aizoaceae, Sesuvioideae) in the Southern Cone

“…As part of the ongoing floristic and taxonomic studies of Aizoaceae (see e.g., Jocou et al 2019a, Jocou & Minué 2020, Jocou et al 2020a) and floristic and ecological studies in Argentina (see e.g., , Minué & Gandullo 2019, Jocou et al 2019b, 2020b, Jocou & Brignone 2020, Minué et al 2021, we revised the genus Sesuvium for the Southern Cone.…”
