New records of Acacia cyclops, Atriplex suberecta, Heliotropium curassavicum, Paspalum dilatatum, P. notatum, Pluchea ovalis, Pulicaria paludosa, Sclerophylax spinescens and Solanum villosum subsp. miniatum confirm their recent expansion on the island of Tenerife. New records are provided for the recently described Sporobolus copei. Finally, Paspalum vaginatum (hitherto possibly confused with P. distichum) and Potentilla indica are confirmed from the island of Tenerife.}, keywords = {Canary Islands, chorology, new records, Tenerife, vascular plants}, issn = {0010-0730}, doi = {10.3989/collectbot.2011.v30.007}, url = {http://collectaneabotanica.revistas.csic.es/index.php/collectaneabotanica/article/view/186/188}, author = {Filip Verloove and J.

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.}, keywords = {chorology, Europe, identification, Jarava, Nassella, neophytes, taxonomy}, author = {Filip Verloove} }
