Kurzbeschreibung

Potamogeton schweinfurthii A. Benn., a new species for Europe

Zusammenfassung

The species of Potamogeton L. (Potamogetonaceae) in Europe are relatively well known. It was the contribution of taxonomists such as A. Bennett, G. Fischer, J. O. Hagström, J. E. Dandy and G. Taylor who, in the first half of 20th century, stabilized the number of recognized Potamogeton species occurring in western, central and northern Europe. In his treatment for Flora Europaea (manuscript finished before 1976) Dandy (1980) recognized 22 species of Potamogeton occurring in Europe. At that time Potamogetonaceae of E Europe were independently being revised by A. A. Mäemets. Her studies led to the discovery of a new species P. sarmaticus Mäemets (Maemets 1979) and extensions in the range in Europe of the predominantly Siberian species P. subsibiricus Hagstr. (Miaemets 1980) and P. subretusus Hagstr. (Myaemets 1979). The tradition of European taxonomic research on Potamogetonaceae culminated in the degree of precision and completeness in a recent monograph of British pondweeds by Preston (1995). Occasional attempts to split the widely accepted species into many poorly defined “small” species are generally not adopted by other researchers (see Kaplan 2002 for a review of two examples). Because the species are well known, contemporary European Potamogeton taxonomy concentrates on the hybrids, particularly their diversity and life history (e.g., Bobrov & Reshetnikova 2002, Fant et al. 2001a, 2001b, 2003, Fant & Preston 2004, Hollingsworth et al. 1995, 1996, Kaplan 2001, Kaplan & Fehrer 2004, Kaplan & Wolff 2004, Kaplan et al. 2002, King et al. 2001, Preston et al. 1998a, 1998b, 1999, Wolff et al. 1997, Zalewska-Gałosz 2002) rather than on the species (e.g. Kaplan & Štěpánek 2003).
