The identity of the North American xenophyte Scirpus atrovirens in France was critically reassessed. Nearly all known populations (notably those from the departments Aisne, Jura, Pas-de-Calais and Sa\ône-et-Loire) turned out to be referable to a closely related species, S. hattorianus. Distinguishing features for three species from the S. atrovirens complex (i.e. S. atrovirens s. str., S. georgianus and S. hattorianus) are compared and discussed. An identification key and SEM photographs of their achenes are provided. The ecology and degree of invasiveness of S. hattorianus in France are also briefly discussed.

In the present paper C. echinatus is reported for the first time from Spain and confirmed for Egypt and Israel. C. longispinus, up to present widely confused with C. spinifex, is reported for the first time from Croatia, Greece, Israel and Morocco and furthermore confirmed for France (including Corse) and Italy. Finally, C. spinifex is confirmed for France, Italy and Spain, while records from Greece and Israel proved to be in error for C. longispinus. All three species are much alike and widely confused in the studied area. In some areas (especially in parts of Italy and Israel) two species occur sympatrically, which largely added to the confusion.
