Further information

The latest related observation in literature was made by L. Reichling in 1988 near Berdorf. Unfortunately, the only site ever known in Luxembourg was definitely destroyed in 2004 (Schwenninger in litt.); so the status has to be revised from CR – critical to RE – regionally extinct.

Description

Equisetum × moorei Newman is the hybrid of Equisetum hyemale × E. ramosissimum. It was first discovered for Luxembourg in 2011 [Steinfort, Schwarzenhaff (60,1/81,3; L8.51.24), 31.8.2011 (B. Pétrement, B. Diethelm)].

Equisetum x litorale

Description

Equisetum × litorale Kühl. ex Rupr. is the hybrid of Equisetum arvense × E. fluviatile. It was first discovered for Luxembourg in 2003 [Noertrange, Säitertbaach (60,5/117,4; K8.11.23), near the river, 27.8.2003 (Y. Krippel, A. Scheer) (hb. Krippel)].

Equisetum × litorale is however easily disregarded, as the hybrid is – from the morphologic point of view – often similar to one of the parents (Jeßen 1987, Lambinon et al. 1992). The frequency in the region is considered of being rare, but is probably underestimated. E. × litorale is known from the neighbouring countries, for example in the Saarland (Parent 1997, Sauer 1993) and in the French Ardennes (Bizot 2000).
