(Paniceae, Poaceae) in the Mediterranean area0 ataxonomic revision of nonnative Cenchrus sstr Paniceae Poaceae i  c6/2012  a67-750 v413 aThe exact identity of non-native, naturalised populations of Cenchrus s.str. in the Mediterranean area has been critically assessed. A herbarium revision confirmed the presence of three species: Cenchrus echinatus, C. longispinus and C. spinifex (syn.: C. incertus). 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. Main features for their distinction are discussed and a dichotomous key for the identification of the native and non-native species of Cenchrus s.str. in the Mediterranean area is presented.10aGRAMINEAE; CENCHRUS ECHINATUS; CENCHRUS LONGISPINUS; CENCHRUS SPINIFEX; TAXONOMY; CHOROLOGY1 aVerloove, Filip1 aGullón, Enrique, Sánchez  uhttp://www.ingentaconnect.com/content/bgbm/will/2012/00000042/00000001/art0000701340nas a2200205   4500008004100000245009300041210006900134300001200203490000700215520063800222653001800860653001000878653002300888653002600911653001300937653001400950100002000964700001900984856013101003       2007                        eng d00aStudies in the genus Paspalum (Paniceae, Poaceae) in Europe – 2. The Quadrifaria group0 aStudies in the genus Paspalum Paniceae Poaceae in Europe 2 The Q  a423-4300 v373 aThe South American Paspalum quadrifarium has been reported as a naturalized xenophyte in Tuscany and Liguria, Italy, since at least the 1960s. In the present contribution the discovery of the closely related P. exaltatum, also of South American origin, in Liguria, Italy, is reported. These are the only known occurrences in Europe of both species, which are very similar to each other and likely to be confused. In the present paper their diagnostic features are discussed and original line drawings and SEM photographs for both taxa are presented. Their current distribution in Italy is shown and some ecological remarks are added.10adistribution.10aItaly10aPaspalum exaltatum10aPaspalum quadrifarium10ataxonomy10axenophyte1 aVerloove, Filip1 aReynders, Marc  uhttps://alienplantsbelgium.myspecies.info/content/studies-genus-paspalum-paniceae-poaceae-europe-%E2%80%93-2-quadrifaria-group
