TY - JOUR T1 - Further notes on Cyperaceae in the Iberian Peninsula: corrections, adjustments and additions JF - Flora Mediterranea Y1 - 2010 A1 - Filip Verloove A1 - Enrique Sánchez Gullón SP - 141 EP - 147 KW - Cyperus KW - Eleocharis KW - Iberian Peninsula AB - Recent 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).

KW - Belgium KW - Camp du Poteau KW - Gironde KW - Invasive plants KW - Landes KW - Natura 2000 KW - Plantes invasives AB - Andropogon virginicus, a grass of American origin (yet pretty widely naturalized out of its natural area) was discovered in 2006 on the military camp at Le Poteau (departments of the Landes and Gironde). The fortuitous introduction of the species is very likely linked to the storage of NATO ammunition in the camp. Andropogon virginicus seems to be perfectly naturalized there and displays an invasive behaviour. This justifies the setting up of information and communication logistics, partly supported within the framework of the Natura 2000 network. In this article, the diagnostic characters, ecology, habitat and the original and secundary distribution are presented.

It is more or less widely naturalised in northwestern Italy (provinces of Biella, Novara, Torino and Vercelli) and probably largely overlooked elsewhere as a result of confusion with J. tenuis. Diagnostic features of both species (and other members of the J. tenuis group currently found in Europe, viz. J. anthelatus and J. dudleyi) are critically assessed and an identification key is presented. Taxonomy and nomenclature of J. dichotomus are discussed, especially with regard to the status of J. platyphyllus, and notes on its present distribution in Italy and its ecology are provided. Like J. tenuis, it often grows in valuable natural and seminatural habitats and locally seems to behave like an invasive environmental weed.

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 “invaders in disguise” and therefore constitute a real problem for conservation management.

Verloove sp. nov. is described and illustrated. It has been known since at least the 1970s on the island of Tenerife (Canary Islands, Spain). Until now it has been confused with both Sporobolus diandrus and S. indicus. Its origin and affinities are discussed. A status as very locally naturalised xenophyte seems most reasonable.
