First appointment of the invasive Cyperus eragrostis (Cyperaceae) as an established species in Tunisia

Abstract

online.The South American weed Cyperus eragrostis Lam. (Cyperaceae) is reported for the first time in the wild from Tunisia, North Africa. A brief description of the species is given and it is illustrated in its Tunisian habitat. Its actual distribution is presented and discriminatory characteristics as compared to C. flavescens, a native species with which it has been confused for some time, are commented.

A new species for the vascular flora of Algeria: Cyperus eragrostis (Cyperaceae)

“…with oilseed crops, rice varieties and sheep's wool) (Petřík, 2003). This species was not reported in the Algerian flora cited above, as well as the flora of the neighboring countries Tunisia (Cuénod et al, 1954;Le Floc'h et al, 2010); although in May 2021 El Mokni and Verloove confirm the presence of C. eragrostis as a naturalized species along and around some ponds and streams within Kroumiria region (NW of Tunisia) after several years of confusion in the identification of the species (El Mokni & Verloove, 2021). In Morocco the authors (Fennane et al, 2014) report the presence of C. eragrostis as a weed, it seems to us that it is not yet naturalized in this country, because its occurrence is restricted to the crop fields.…”

Inventory of the urban flora of Budapest (Hungary) highlighting new and noteworthy floristic records

“…Native to South America, but occurs in southern, western and central Europe, North Africa and North America as an alien introduced as an ornamental ( Mokni and Verloove 2021 ), with some recent Hungarian records ( Mesterházy 2021 ). These are the first records of the plant from Budapest.…”
