	abstract = {Misidentifications are an important but neglected problem in studies on plant invasions. This review shows how taxonomic education of staff and stakeholders is of great importance for correctly assessing threats provoked by alien plant species in field and literature based studies. Four randomly chosen recent examples (Digitaria violascens, Eleocharis pellucida, Juncus dichotomus and Vicia dalmatica) from Europe demonstrate that, as a result of an initial erroneous identification and/or confusion with similar harmless species, potentially noxious environmental weeds have been able to become fully naturalised. They act as {\textquotedblleft}invaders in disguise{\textquotedblright} and therefore constitute a real problem for conservation management.},

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.},

	abstract = {A taxonomic revision of the naturalized representatives of the South American genera Jarava Ruiz
\& Pav. and Nassella (Trin.) E. Desv. (segregates of Stipa L. s.l.) in Europe revealed several interesting
data. Eight taxa are currently regarded as, at least locally, naturalized in the Iberian Peninsula,
Macaronesia, France (incl. Corsica) and/or Italy : Jarava ambigua (Speg.) Pe{\~n}ail., J. brachychaeta
(Godr.) Pe{\~n}ail., J. caudata (Trin.) Pe{\~n}ail. and J. plumosa (Spreng.) S. W. L. Jacobs \& J. Everett, and
Nassella neesiana (Trin. \& Rupr.) Barkworth, N. poeppigiana (Trin. \& Rupr.) Barkworth, N. tenuissima
(Trin.) Barkworth and N. trichotoma (Nees) Arechav. Nassella mucronata (Kunth) R. W. Pohl
has not been confirmed, all actual European populations being definitely ascribable to the closely
related N. neesiana. Particular attention is paid to the confusion of both taxa in Europe and useful
diacritic features for their distinction are discussed. Only two taxa have become more or less
widespread to date (N. neesiana and N. trichotoma), both being present respectively in all or
nearly all investigated countries. Two further taxa (Jarava brachychaeta and J. caudata) also tend
to increase. Jarava ambigua (confused with J. brachychaeta in S-France) is cited for the first
time as a naturalized alien in Europe. All taxa but Nassella tenuissima (which is an escape from
cultivation) are believed to have been introduced unintentionally ; all are of American origin.
Each taxon is described and a dichotomous key, original line drawings of all species{\textquoteright} anthecia and
further chorological, nomenclatural, taxonomic and ecological data are provided.},
