(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/art0000701664nas a2200181   4500008004100000022001400041245009700055210006900152300001200221490000700233520109600240653001201336653001501348653002201363100002001385700003101405856004601436       2010                        eng d  a1120-405200aFurther notes on Cyperaceae in the Iberian Peninsula: corrections, adjustments and additions0 aFurther notes on Cyperaceae in the Iberian Peninsula corrections  a141-1470 v203 aRecent fieldwork and herbarium revisions have considerably improved the taxonomic knowledge
of genera Cyperus and Eleocharis (Cyperaceae) in the Iberian Peninsula. In this paper
new records are provided for Cyperus aggregatus (2nd record in the province of Huelva, Spain)
and C. serotinus (first report from Andalucia). Cyperus croceus and C. retrorsus are reported
for the first time from the Iberian Peninsula and, apparently, also from Europe. Previous
Spanish records of Cyperus cyperoides turned out to be in error for C. retrorsus. Analogously,
the name Cyperus bellus given as naturalized at the Laguna Chica in Moral de Calatrava (Spain)
has to be changed to a still unidentiffied species of Cyperus. C. esculentus var. macrostachyus
– a distinct American variety – is a naturalized weed of arable land in northeastern Spain.
Finally, part of the collections of Eleocharis flavescens from the Iberian Peninsula are in fact
proved to belong to E. caduca, a weed from the Old World tropics. Genuine Eleocharis
flavescens is here confirmed from Baixo Alentejo (Portugal).10aCyperus10aEleocharis10aIberian Peninsula1 aVerloove, Filip1 aGullón, Enrique, Sánchez  uhttp://www.herbmedit.org/flora/20-141.pdf
