Despite its proximity to cities with important botanical institutions such as Madrid and Salamanca, and its location between important mountain ranges (Gredos and Malagón mountain ranges), the flora of the province of Ávila had not been studied comprehensively until now. In this article, we present the first checklist of the vascular flora of this...
Carex nigra is a widespread sedge in the northern hemisphere. Some subspecies have been proposed within C. nigra s.l., reflecting the complex morphological and biogeographical variability within the group. Given this variability and its widespread distribution, we aim to (i) study the phylogeography of C. nigra s.l. by reconstructing the evolutiona...
The fundamental value of universal nomenclatural systems in biology, and the key to their success, is that they have enabled unambiguous scientific communication among and across different cultures. These systems are codified in sets of rules for zoology, botany, and other branches of biology. Nomenclatural codes have been collectively developed fo...
The fundamental value of universal nomenclatural systems in biology is that they enable unambiguous scientific communication. However, the stability of these systems is threatened by recent discussions asking for a fairer nomenclature, raising the possibility of bulk revision processes for "inappropriate" names. It is evident that such proposals co...
Introduction. Specimens of Sphaerocarpos collected during 2022 from the central Iberian Peninsula did not match any previously known species of this genus. Examination of other herbarium material revealed three identical specimens from three different localities in Spain. These were also morphologically identical to Portuguese specimens previously...

إن القيمة الأساسية لأنظمة التسميات العلمية العالمية في علم الأحياء هي أنها تمكن من التواصل العلمي بشكل سلس ولا لبس فيه. ومع ذلك، فإن استقرار النظام الحالي معرض للخطر. وقد طالبت بعض المناقشات الأخيرة بوضع تسميات أكثر عدالة. تشير هذه المناقشات إلى ضرورة فتح عمليات مراجعة جماعية للأسماء "غير المناسبة". ومن الواضح أن مثل هذه الادعاءات تأتي من مشاعر إنس...
分類学は生物多様性を理解するための基盤であり、生物学的命名システムは国際的な科学コミュニケーションを促進する重要な役割を果たしている。しかし、植民地主義や差別などの社会的問題を反映した「不適切な」学名について一括改訂による見直しが提案されている。一方で、このような一括改訂プロセスによって、生物学的命名システムの安定性が損なわれる可能性がある。科学コミュニティは、生物学的命名システムがもたらす４つの価値である普遍性、安定性、中立性、超文化性を維持することの重要性を認識し、科学的命名法に政治的な影響を与える提案には慎重に対応する必要がある
Biyolojideki evrensel isimlendirme sistemlerinin temel değeri, kesin bilimsel iletişimi mümkün kılmalarıdır. Ancak sistemin istikrarı tehlikeye girer. Son tartışmalar daha adil bir isimlendirme çağrısında bulundu. Bu tartışmalar “uygunsuz” isimler için toplu inceleme süreçlerinin açılmasını öneriyor. Bu tür argümanların derin duygulardan kaynakland...
생물학에서 보편적 명명 체계의 근본적인 가치는 그것이 명확한 과학적 의사소통을 가능하게 했다는 것입니다. 그러나 시스템의 안정성이 손상되었습니다. 최근 토론에서는 좀 더 공정한 명명법을 요구했습니다. 이러한 논쟁은 "부적절한" 이름에 대한 대량 수정 프로세스의 개시를 제안합니다. 그러한 주장이 매우 깊은 감정에서 나온 것은 분명하지만, 이러한 주장 중 일부의 결과가 비판적 분석을 받았는지 여부는 불분명합니다. 생물학적 의사소통 시스템은 돌이킬 수 없을 정도로 손상될 수 있으며, 결과적으로 이에 의해 표현되는 과학도 손상될 수 있습니다. . 우리는 명명법의 객관적인 코드가 필요한 바로 그 이유에서 발생하는 네 가지 필수...

O valor fundamental dos sistemas nomenclaturais universais em biologia é que eles permitiram uma comunicação científica inequívoca. No entanto, a estabilidade do sistema está comprometida. Discussões recentes pediram uma nomenclatura mais justa. Estes debates sugerem a abertura de processos de revisão em massa para nomes “inadequados”. É evidente q...
Cryptangieae has recently been revised based on morphology and molecular phylogeny, but cytogenetic data is still scarce. We conducted this study with the aim of investigating the occurrence of holocentric chromosomes and pseudomonads, as well as understanding the mode of chromosomal evolution in the tribe. We performed analyses of meiotic behavior...
Фундаментальная ценность универсальных номенклатурных систем в биологии заключается в том, что они обеспечивают недвусмысленную научную коммуникацию. Однако стабильность системы нарушена. Недавние дискуссии потребовали более справедливой номенклатуры. Эти дебаты предполагают начало процесса массового пересмотра «неуместных» названий. Очевидно, что...
生物学中通用命名系统的基本价值在于它们实现了明确的科学交流。 然而，系统的稳定性受到损害。 最近的讨论要求采用更公平的命名法。 这些辩论表明对“不适当”的名称启动批量修改流程。 显然，这些争论来自非常深刻的感受，但尚不清楚其中一些主张的后果是否受到了批判性分析：生物通讯系统可能受到不可挽回的损害，反过来，它所阐述的科学也会受到损害。 。 我们想明确提出四个基本考虑因素，这些考虑因素正是我们需要客观的命名规则的原因：普遍性、稳定性、中立性和跨文化性。 我们这些考虑因素是 1. 公平公正地指导生物命名法的原则，2. 允许生物学中明确的普遍交流。 因此，任何主观建议都不应破坏它们。

In this study, we conducted an integrative systematic study based on molecular, morphological and cytogenetic data to elucidate the taxonomic status of seve...
• Background and Aims: While variation in genome size and chromosome numbers and their consequences are often investigated in plants, the biological relevance of variation in chromosome size remains poorly known. Here, we examine genome and mean chromosome size in the cyperid clade (families Cyperaceae, Juncaceae, Thurniaceae), which is the largest...
Broˇzov´a et al. (2022) present a study, “Toward finally unraveling the phylogenetic relationships of Juncaceae with respect to another cyperid family, Cyperaceae”, with the premise of revising the phylogenetic re-lationships in Juncaceae and Cyperaceae based on Sanger sequencing of one nuclear rDNA (ITS) and two plastid regions (the gene rbcL and t...
In this paper we report the presence of Carex olbiensis (Cyperaceae) in the CW Iberian Peninsula (Sierra de Gredos, Extremadura region), which represents an important disjunction in relation to the known range of the species and its westernmost new limit. We revised the distribution of this species, which resulted in the likely exclusion of the spe...
Carex subgenus Psyllophorae is an engaging study group due to its early diversification compared to most Carex lineages, and its remarkable disjunct distribution in four continents corresponding to three independent sections: sect. Psyllophorae in Western Palearctic, sect. Schoenoxiphium in Afrotropical region, and sect. Junciformes in South Americ...
Carex section Schoenoxiphium (Cariceae, Cyperaceae) is endemic to the Afrotropical biogeographic region and is mainly distributed in southern and eastern Africa, with its center of diversity in eastern South Africa. The taxon was formerly recognized as a distinct genus and has a long history of taxonomic controversy. It has also an important morpho...
Cyperaceae (sedges) are the third largest monocot family and are of considerable economic and ecological importance. Sedges represent an ideal model family to study evolutionary biology because of their species richness, global distribution, large discrepancies in lineage diversity, broad range of ecological preferences, and adaptations including m...

Carex section Phacocystis (Cyperaceae) is one of the most diverse and taxonomically complex groups of sedges (between 116‐147 spp.) with a worldwide distribution in a wide array of biomes. It has a very complicated taxonomic history, with numerous disagreements among different treatments. We studied the biogeography and niche evolution in a phyloge...
Changes in chromosome number as a result of fission and fusion in holocentric chromosomes have direct and immediate effects on genome structure and recombination rates. These in turn may influence ecology and evolutionary trajectories profoundly. Sedges of the genus Carex (Cyperaceae) comprise ca. 2000 species with holocentric chromosomes that evol...
Restriction‐site associated DNA sequencing (RAD‐seq) and related methods have become relatively common approaches to resolving species‐level phylogeny. It is not clear, however, whether RAD‐seq data matrices are well suited to relaxed‐clock inference of divergence times, given the size of the matrices and the abundance of missing data. We investiga...
Phylogenetic studies of Carex L. (Cyperaceae) have consistently demonstrated that most subgenera and sections are para‐ or polyphyletic. Yet taxonomists continue to use subgenera and sections in Carex classification. Why? The Global Carex Group here takes the position that the historical and continued use of subgenera and sections serves to (1) org...
The species shows a restricted extent of occurrence (EOO) and area of occupancy (AOO) of 8 km2. Nevertheless, no declines or fluctuations in either EOO or AOO, number of mature individuals or localities nor habitat quality have been reported. Thus, we cannot consider this species to be Endangered (EN) under criterion B. For these reasons, the speci...
In the present paper, 43 chorological novelties for Gredos range (Central System, Spain) are showed. These citations are the result of the works leaning to the elaboration of the sierra de Gredos vascular flora catalogue. Some of them pose relevant disjunctions regarding their known Iberian distribution, as the cases of Myosotis hervei Sennen, Cype...
The field of systematics is experiencing a new molecular revolution driven by the increased availability of high-throughput sequencing technologies. As these techniques become more affordable, the increased genomic resources have increasingly far-reaching implications for our understanding of the Tree of Life. With c. 2000 species, Carex (Cyperacea...
Carex acocksii is a sedge species known only from two populations in the Karoo of the Northern Cape in South Africa. It was described from a single locality (Hantam Mts., Calvinia) more than twenty years ago, and tentatively ascribed to section Petraea because of its unispicate inflorescence and utricles with membranaceous-papyraceous walls. Howeve...
One of the most common processes shaping evolution in plants could be the introgression or hybridization between species. We sampled a putative hybrid population of Carex × boenninghausiana recently discovered from Sicily (Italy), and one specimen of each of the parent species of this hybrid (C. paniculata and C. remota) from the same area. We perf...
La presente guía recoge una selección de las plantas vasculares del municipio de El Oso (La Moraña, Ávila), que cuenta con interesantes especies adaptadas a los suelos salinos.
In the present paper, 58 chorological novelties for Gredos range (Central System, Spain) are showed. Some of them represent important disjunctions with respect to known Iberian distribution, as the cases of Cytinus ruber (Fourr.) Fritsh, Isolepis fluitans (L.) R.Br., Alyssum montanum L. and Lysimachia ephemerum L. Some species, such as Carex lainzi...
The megadiverse genus Carex (c. 2000 species, Cyperaceae) has a nearly cosmopolitan distribution, displaying
an inverted latitudinal richness gradient with higher species diversity in cold‐temperate areas of the Northern
Hemisphere. Despite great expansion in our knowledge of the phylogenetic history of the genus and many molecular
studies focusing...
Una especie nueva de Linaria sect. Supinae en la Sierra de Gredos (Sistema Central, Península Ibérica)Linaria vettonica Luceño, Mazuecos & P. Vargas, a new species of Linaria sect. Supinae, is described. It is a narrow endemic inhabiting the southern hills of the western and central massifs of Sierra de Gredos (Sistema Central mountains, Iberian Pe...
Holocentric chromosomes are characterised by the presence of kinetochoric activity along the chromosome length. This atypical chromosomal architecture has evolved independently in a wide array of lineages across the tree of life. Different mechanisms have been developed to overcome meiotic problems posed by holocentry, such as inverted meiosis and...
Large-scale changes in chromosome number have been associated with diversification rate shifts in many lineages of plants. For instance, several ancient rounds of polyploidization events have been inferred to promote genomic differentiation and/or isolation and, consequently, angiosperm diversification. Dysploidy, although less studied, has been su...
Here we report chromosome number counts from the sedge family (Cyperaceae), most of which correspond to genus Carex from the Nearctic and western Palearctic. In addition, counts are reported for some Neotropical and Afrotropical sedges. We provide the first known chromosome counts for the subfamily Mapanioideae, 5 genera (Lagenocarpus,
Afroscirpoi...

Ecology. Neotropical Carex grow in cold--...
Despite most of the cytogenetic research is focused on monocentric chromosomes, chromosomes with kinetochoric activity localized in a single centromere, several studies have been centered on holocentric chromosomes which have diffuse kinetochoric activity along the chromosomes. The eukaryotic organisms that present this type of chromosomes have bee...
Specimens of Andreaea sect. Andreaea collected in Lesotho show morphological differences from the remaining Sub-Saharan Africa species in the group. Particularly, Lesotho specimens have much larger spores, a character diagnostic in the genus. Spore size also separates the Lesotho specimens from typical A. rupestris from the Northern Hemisphere. Con...
