  • In this article I reconsider the lectotypification of the name Carex ledebouriana C. A. Mey. ex Trevir. (Cyperaceae). In 1833, Meyer described an unnamed variety of C. capillaris L. based on the gatherings of Ledebour from two localities (river Koksun and near Riddersk) in what is today the Kazakhstan Altai. In 1863, Treviranus validly published the name C. ledebouriana, referring to Meyer's unnamed variety and erroneously citing a gathering by Bunge “in summis alpibus Kuraicis”. A herbarium sheet at LE with barcode LE 01006839 was proposed as the (lecto)type of C. ledebouriana by Egorova in 1999 and this was confirmed by Grabovskaya-Borodina in 2012. In studying the original material, I found that sheet LE 01006839 in fact consists of three fragments belonging to two different gatherings and has an incorrect label. These two gatherings are further represented at LE by sheets LE 01006840 and LE 01006841, respectively. I argue that sheet LE 01006839 is not eligible as a type specimen because it consists of two gatherings. Instead, I designate here as the lectotype sheet LE 01006841, which contains well-preserved plants collected by Ledebour with mature utricles.
