Summary: A lectotype for the name Carex curvata Knaf has been chosen from a herbarium specimen located in the PR (National Museum, Prague). The selected specimen appears to align with the original concept of the name as described by the author, as evidenced by the author's herbarium label containing the same locality mentioned in the protologue. Taxonomic notes on the identification of similar and related species have been provided to complement the typification.

Summary: This study examined the ability of native Cyperaceae from western Japan to form dauciform roots and their potential contribution to soil phosphorus dynamics. Results showed a negative correlation between the number of dauciform roots and soil and plant phosphorus status, indicating the importance of dauciform roots in acquiring poorly-available soil phosphorus.

Summary: Carex section Schoenoxiphium is a species endemic to the Afrotropical region, mainly found in southern and eastern Africa. Through a comprehensive study using morphological, molecular, and cytogenetic data, 21 species were identified, including one newly described species. Previous molecular works identified five main lineages in Schoenoxiphium, which were confirmed in this study.

Summary: The study highlights the differences in concentrations of major and trace elements among different sedge species, but overall, their elemental composition is similar to grasses, providing valuable insights for meadow management. The presence of sedges can enhance the fodder value of meadows, making them a valuable component of economically important meadow communities.

Summary: Microsatellite primers were developed and tested to genotype different populations of Carex curvula and to infer the phylogeographic relationships within the species and between its two subspecies. The results showed that the developed markers were efficient in distinguishing between the subspecies and populations, making them promising tools for evolutionary studies.

Summary: Phylogenetic studies of Carex L. have shown that most subgenera and sections are para- or polyphyletic, yet taxonomists continue to use them for classification. The Global Carex Group argues that the historical and continued use of subgenera and sections helps organize lineages, create identification mechanisms, and recognize morphologically diagnosable lineages. While a global reclassification based on phylogenetic relationships is not yet possible, an intermediate step of implementing revised subgenera and using a combination of informally named clades and formally named sections has been taken to reflect current knowledge.

Summary: Carex malipoensis, a new species from southeast Yunnan, China, is morphologically similar to C. trichophylla in sect. Euprepes, but can be distinguished by its longer inflorescences and peduncles, pendulous spikes, hispidulous female glumes, densely hispidulous utricles, and longer nutlets.

Summary: The study revealed that interspecific gene flow between Carex angustisquama and its related species has been limited both currently and historically. Bayesian inference of historical gene flow indicated that extrinsic factors may act as isolating barriers between Carex species, with hybrid breakdown via microhabitat segregation being a potential barrier. This provides insights into the evolutionary process of an extremophyte in solfatara fields and the mechanisms of diversification of the speciose genus Carex.

Summary: Carex laevissima Nakai 1914, a vital plant for ecological conservation and land virescence, was analyzed in this study to further understand the genetics of Carex plants. The chloroplast genome of Carex laevissima, which was 188,029 bp in length, was systematically analyzed and found to have a high GC content. Phylogenetic analysis revealed a close relationship between Carex laevissima and Carex neurocarpa.

Summary: The genomic architecture aids in chromosome recognition, pairing, and recombination, with telomeres and subtelomeres playing crucial roles in facilitating these processes. While telomeres contribute to homologous pairing, subtelomeres also play a significant role in recombination. In plant breeding, understanding how homologous chromosomes initiate pairing can be instrumental in manipulating chromosomes for hybridization and interspecific genetic crosses, promoting recombination for transferring desirable traits from related genetic donor species into crops.

Summary: A new hybrid species called Carex xpayettei has been discovered in nine locations in Northern Quebec, Canada, between the North American Carex atratiformis and the circumboreal Carex media. The hybrid displays intermediate morphology, is not completely sterile, and often produces fruits. Pollen stainability of the hybrid ranges from 10% to 37%, while its parents have values above 95%.

Summary: In this study, the hybridization of closely related species Carex vulpina, C. otrubae, and C. remota was investigated through morphological analysis and DNA barcoding. The results provided insights into the morphological and genetic relationships between these species and their hybrids. Morphological analysis identified useful traits for hybrid identification, and DNA barcoding was effective in distinguishing hybrids. Nomenclatural notes were also provided for the hybrids.

Summary: Anticipating the evolutionary responses of species to climate change is crucial for effective management and conservation measures. This study investigates the impact of climate change on two Western Mediterranean sister species through the comparison of genetic diversity, potential distribution, and ecological space. The findings reveal a strong genetic structure driven by geography in both species, with lower genetic diversity and narrower ecological space in the restricted endemic species. Future projections suggest a dramatic reduction of suitable areas for both species. Conservation measures need to be implemented.

Summary: This study documents the first occurrence of Carex phyllostachys in the Croatian flora. The rare Euro-Caucasian species was found on Mt Mosor in central Dalmatia in June 2019. This record represents the north-western distribution limit of the species. The habitat, ecology, and morphological similarities with allied species are discussed, along with an identification key provided for Carex species in Croatia belonging to the subgenus Indocarex.

Summary: Through morphological and genetic analysis, a close relationship between Carex buxbaumii and C. hartmaniorum was revealed, with the latter showing more homogeneity in both morphology and genetics. Populations of C. buxbaumii exhibited greater variability, with distinct genetic and morphological differences observed in populations from Poland and Estonia compared to other populations. Further studies are needed to determine the taxonomic status of infraspecific taxa within C. buxbaumii.

Summary: This study examined the phenotypic plasticity and the effect of soil conditions on the morphology of Carex buekii. A total of 487 specimens were collected from Hungary, Poland, and Slovakia. The results showed that soil conditions, particularly potassium, had a significant impact on the morphology of C. buekii. This relationship is also relevant to important taxonomic traits in sedges.

Summary: Species within the Carex section Ammoglochin are difficult to distinguish, due to their similarity and a lack of clear-cut morphological characters. In Poland, all seven European species have been recorded. These taxa can be reliably determined by looking at a combination of characters. Carex arenaria, C. brizoides, and C. praecox are the most common types in Poland, while C. colchica, C. curvata, and C. pseudobrizoides are much rarer.

Summary: The protocols for in situ hybridization techniques can vary, but they usually involve denaturation and hybridization steps. Formamide is commonly used to lower the melting temperature in ISH, while non-toxic ethylene carbonate can achieve similar high-quality results as formamide.
