“…Variability of morphological characters observed in sedges could have resulted from habitat conditions, as demonstrated in the sections Ceratotystis Dumort. (e.g., Więcław & Podlasiński, 2013 ; Więcław, 2017 ) and Phaestoglochin Dumort. (e.g., Janyszek & Jagodzinski, 2009 ; Jagodziński et al, 2017 ).…”

“…The morphological distinctness of the specimens from that population (number 1) resulted primarily from differences in the utricle size, i.e., a generative character, most important in the identification of Carex taxa (Chater, 1980;Egorova, 1999). Generative characters in seed plants are, as a rule, less variable than the vegetative ones (e.g., Rakić et al, 2012;Preston, 2013), but both character groups are more or less closely associated with a taxon's adaptation to local habitat conditions (e.g., Hereford, 2009;Raabová, Münzbergová & Fischer, 2011;Więcław, 2017). It is highly probable that the morphology of C. hartmaniorum was affected by the relatively nutrient-rich and specific coastal habitat of the island of Terschelling (Westhoff & Ketner, 1967).…”

“…In nature, intraspecific differences may be underlain by numerous mechanisms, including local adaptations, phenotypic plasticity, parental conditions, and selection (Violle et al, 2012). As shown by studies on the C. flava complex, periodic flooding, local desiccation, trampling, sun exposure or local edaphic conditions may lead to the emergence of different morphotypes (Więcław & Podlasiński, 2013;Więcław, 2017). In addition, the type of land use (grazing, mowing) may affect plant morphology as well (e.g., Meer van der et al, 2014;Kostrakiewicz-Gierałt, Stachurska-Swakoń & Towpasz, 2018).…”

Background Carex buxbaumii and C. hartmaniorum are sister species of the clade Papilliferae within the monophyletic section Racemosae. An unambiguous identification of these species is relatively difficult due to the interspecific continuum of some morphological characters as well as the intraspecific variability. The study was aimed at determining the range of variability, both morphological and genetic, within and between these two closely related and similar species. Methods The sedges were collected during botanical expeditions to Armenia, Estonia, the Netherlands, and Poland. The morphological separation of the two species and their populations was tested using the Discriminant Function Analysis (DFA). The genetic variability of the 19 Carex populations was assessed in the presence of eight Inter Simple Sequence Repeat (ISSR) primers. Results Results of the study indicate a considerable genetic affinity between the two sedge species (mean Si = 0.619). However, the populations of C. hartmaniorum are, morphologically and genetically, more homogenous than the populations of C. buxbaumii. Compared to C. hartmaniorum, C. buxbaumii usually has wider leaf blades, a shorter inflorescence, a lower number of spikes which are shorter, but wider, and longer bracts and utricles. The AMOVA showed a larger variation between the populations of C. buxbaumii, representing 25.65% of the total variation in the taxon. Two populations of C. buxbaumii (from Poland and Estonia) are separated from the remaining populations, both genetically and morphologically; their individuals show shorter utricles and glumes, compared to the typical specimens of C. buxbaumii, and correspond with the morphology of putative infraspecific taxa described by Cajander (var. brevisquamosa and var. confusa). Conclusions The taxonomic status of the putative infraspecific taxa within C. buxbaumii requires further studies throughout the distribution range of C. buxbaumii, addressing habitats, morphology and genetics (including a chromosome count or a combination of different genetic methods), particularly as the variability in C. buxbaumii may be associated with the species’ polyploid origin.

“…According to Hájek et al (2008), C. viridula reached a high cover in disturbed moderately rich fens in Bulgaria and occurred with some calciphilous species, for example Eriophorum latifolium and Parnassia palustris. In Poland, C. viridula can also grow at sites with a high soil calcium carbonate level (see also Więcław and Podlasiński 2013) and is capable of colonizing heavily disturbed sites (Więcław 2017). Thus, the ecological niche of C. viridula is very wide, compared to that of C. flava, C. lepidocarpa and C. demissa.…”

The Carex flava complex in Europe is considered consisting of six species (Więcław 2017). These taxa are usually small in size and have short rhizomes; they usually have a solitary subcylindrical male spike on top of the inflorescence, above globose to oblong female spikes with more Hájek 1999;Hájek et al 2005) and Carici flavae-Cratoneuretum (Hájek et al 2005).…”

The Carex flava aggregate belongs to one of the most taxonomically difficult groups of sedges which colonize diverse habitats, from organic to sandy, from acidic to alkaline, usually humid and moist. The study included 129 vegetation plots and ten soil variables (organic matter, phosphorus, potassium, magnesium, calcium, carbonates, carbon, nitrogen, pH, and the ratio between organic carbon and nitrogen). The main aim was to determine the relationships between the various plant communities C. flava agg. occur in and their soil properties. With the aid of the two-way indicator species analysis and cluster analysis, we delimited nine vegetation types from the Scheuchzerio palustris-Caricetea fuscae, Littorelletea uniflorae, Molinio-Arrhenatheretea and Alnetea glutinosae classes differing in their response to soil properties. The CCA revealed pH, N, K, C, CaCO3, P and Ca to be statistically significant, and to account for 11.55% of the total variance in species composition. The largest differences, both in terms of species composition and in soil conditions, were revealed between communities with C. lepidocarpa and C. demissa. Carex lepidocarpa occurred in calcareous and extremely rich fens (Caricion davallianae) whereas C. demissa was found to occur in poor and moderately rich fens (Sphagno-Caricion canescentis, Caricion canescenti-nigrae). Carex flava grew mostly in calcareous, rich fens and wet grasslands (Caricion davallianae, Calthion palustris). Carex viridula was found in both calcareous, extremely and moderately rich fens and wet grasslands, and in nutrient-poor habitats such as dunes and sandy lake shores. The ecological niche of C. viridula is very wide and this species showed no affinity to any specific syntaxon.

Carex heterostachya (CH) and Carex breviculmis (CB) are easy to develop lawns in a short period and exhibit high ornamental value in northwest China with high summer temperatures, uneven rainfall, and poor soil. Several questions are raised, including what type of plant functional traits has they formed for long-term survival and adaptation to this environment, which plant is more adaptable, as well as which leaf functional traits are critical to photosynthetic characteristics. After exploring the leaf functional traits of the two plants by gas exchange technology and eld emission electron scanning technology, the following conclusions are drawn: (a) CB is a slow investment-return plant, which exhibits strong environmental adaptability and plasticity, and is resistant to barrenness, drought and shade. CH is a kind of quick investment-return plant, with high photosynthetic e ciency, well-developed transport tissue, and relatively shade-tolerant. The soil with low water content and poorer soil is suitable for CB cultivation, and CH is suitable for cultivation in the environment with su cient light and rich nutrients. At the same time, both CB and CH can be used to enrich the diversity of understory landscape. (b) Carex have strong environmental adaptability, large variation in leaf structure traits, as well as strong plasticity. Leaf anatomical characters are stable, whereas there are differences in the interspeci c variability and plasticity. (c) Speci c leaf area (SLA) can serve as the main factor affecting the photosynthetic availability of Carex, the thickness of the stratum corneum(CUT), the thickness of the upper(UET) are secondary factors. These nding can provide a theoretical basis for the cultivation and application of Carex and the expansion of turfgrass germplasm resources.
