Abstract:Carex buekii is a rare species, native to Europe and the Middle East, although its full geographical distribution is poorly known. Attention is paid to the global occurrence of C. buekii. Its situation and threat status is presented in relation to each country from which this species is known. Carex buekii forms four (rare) hybrids, each with other members within the section Phacocystis. Special attention is paid to the comparison of Carex buekii with the recently described Central European C. randalpina; the … Show more
“…These localities are situated at distances of 3-10(-19) km from rivers. These plants, which are fully fertile, are very probably introgressants of C. acuta, reproducing generatively (Koopman et al 2018). In contrast, we have found many populations of apparently pure C. buekii in the Czech Republic that bear mostly empty utricles, with fertile ones found only at the base of the lower female spike.…”

“…Carex buekii is a Euro-Siberian species, distributed in central, south-eastern and eastern Europe, westwards reaching Germany (and possibly also Belgium) and southwards extending to Bulgaria. The eastern boundary of its distribution runs through northern Kazakhstan and southern Siberia (Meusel et al 1965, Koopman et al 2018. Carex buekii is typical of riverine reed vegetation; less frequently it also occurs in tall-sedge communities, usually in floodplains, and in ash-alder alluvial forests.…”

Carex buekii
is a tall sedge, forming large stands in wetlands, particularly in river floodplains across Central Europe and thus on many sites determining the typical appearance of riverine habitats. Our paper aims at increasing the knowledge on ecology of
C. buekii
and its role in the wetlands. Field data were collected in Poland, the Czech Republic, Slovakia, Hungary, and Italy.
Carex buekii
usually occurs in nutrient rich habitats, but is also capable of colonising relatively nutrient-poor ones; it grows on both acidic and alkaline soils (pH 3.3–7.4) with diverse concentrations of assimilable elements (Ca, Mg, P, K). One of the most important ecological characteristics of
C. buekii
is its relationship to the floodplains of watercourses. It seems to be dependent on, or at least very tolerant to regular disturbances by streaming, floods and transport of sediments.
Carex buekii
usually forms relatively uniform stands of its own association,
Caricetum buekii
. The species most frequently accompanying
C
.
buekii
are
Urtica dioica
,
Calystegia sepium
,
Galium aparine
,
Rubus caesius
,
Phalaris arundinacea
, and
Cirsium arvense
. The sedge also occurs in the understorey of forests with e.g.
Alnus glutinosa
,
Salix fragilis
,
Padus avium
, and
Quercus robur
.
Carex buekii
is able to colonise man-made or man-changed habitats such as railway embankments and roadsides or regulated river banks. Taking into account the IUCN Red List Criteria we propose to regard
C
.
buekii
as a least-concern (LC).
“…It belongs to the taxonomically intricate C. sect. Phacocystis Dumort., a group of sedges where an inconsistent application of species names by authors has created a great deal of historical taxonomic confusion including uncertainty regarding the identity of C. elata itself (see Jiménez-Mejías & al., 2011, 2014Koopman & al., 2018). The name C. elata All.…”
Carex elata All. is a well‐known species widely distributed in western Eurasia. The name C. elata All. is the oldest name applied to the species of concern, but it was abandoned for C. stricta Gooden soon after publication. At the end of the 19th century and the beginning of the 20th century, different authors dismissed C. stricta Gooden. as a later homonym of C. stricta Lam. and simultaneously resurrected C. elata All. We discuss usage of the name C. elata and propose a neotype to fix its current application.
