Within the taxonomically challenging genus Dianthus, through an integrative approach we tested the taxonomic value of D. brachycalyx, a putative species endemic to mountain peaks of the central‐southern Apennines, with respect to the widespread central‐Mediterranean D. virgineus. We measured 30 morphological characters in 452 individuals from 25 populations and obtained 3202 single nucleotide polymorphisms using ddRAD‐seq techniques in 394 individuals from 36 populations. For climatic niche comparison, we built a dataset of 348 occurrence points. By comparing morphometric, genetic, and climatic niche data, we showed that D. brachycalyx cannot be considered a distinct species. Morphometric separation between the two species is detectable, but high‐elevation populations of D. virgineus are similar to D. brachycalyx. Genetic analyses revealed that the genetic structure of populations of D. brachycalyx and D. virgineus is mainly shaped by isolation‐by‐distance, irrespective of their taxonomic attribution. The climatic niches of the two species are overlapping, and the niche differences are just due to different availability of climatic conditions in their ranges. Accordingly, multiple lines of evidence do not support a separation of D. brachycalyx from D. virgineus, and the former should be considered a heterotypic synonym of the latter.","PeriodicalId":49448,"journal":{"name":"Taxon","volume":"1475 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141866478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study builds upon previous phylogenetic analyses to clarify the generic boundaries of Bolanthus and its associated taxa in Turkey. We used tribe‐wide molecular phylogenies and reviewed the taxonomic history to address the controversies surrounding the classification of Bolanthus. In 2018, a new genus, Graecobolanthus, was proposed for Greek members of Bolanthus, while the monotypic genus Phrynella was synonymized under Bolanthus. Subsequent research suggested that Bolanthus hirsutus, the type of the genus name, aligns with the Greek clade, casting doubt on the validity of Graecobolanthus. Here we suggest the resurrection of the generic name Jordania for the Turkish species of Bolanthus (including Phrynella), with Jordania minuartioides designated as the lectotype. This reclassification aims to resolve the nomenclatural confusion and reflect phylogenetic relationships accurately. According to this concept, the necessary combinations are made.","PeriodicalId":49448,"journal":{"name":"Taxon","volume":"66 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141743570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taxa from each region form a wellsupported monophyletic clade. However, the species circumscription in Asian Caryodaphnopsis remains ambiguous due to few and generally unstable morphological characters used for classification. To address this, we conducted an integrative taxonomy of the Asian clade. We investigated 13 populations, sampled 57 accessions covering the entire taxonomic diversity, geographic range, and morphological variation in Asia, and reconstructed a new phylogeny using single‐nucleotide polymorphisms. We obtained a well‐resolved phylogeny of the Asian Caryodaphnopsis. The first diverged clade consists of three species endemic to lowland forests. The second (largest) clade (eight species in total) mainly occurs in limestone mountain forests and has a double‐layered lower leaf epidermis morphology of type 2 (less complete roomy with closed “roof”) and type 3 (complete roomy with closed “roof”). Based on the diagnostic morphological characters, distinct distributional ranges, and monophyly of each clade, we recognize 12 species in the Asian Caryodaphnopsis, including three new species: C. cangyuanensis sp. nov., C. hekouensis sp. nov., and C. rubrinervis sp. nov. We also reinstate C. latifolia, and re‐circumscribe the widespread C. tonkinensis and other species based on fruit and inflorescence morphology and molecular evidence.","PeriodicalId":49448,"journal":{"name":"Taxon","volume":"46 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141567937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, we examine evidence from inflorescence branching patterns, seed coat, and phylogeny in detail, and contrast circumscriptions of genera with the available data. We also indicate possible consequences of the proposed system for herbarium curators, keepers and users of large databases, and generalist users of identification keys. We argue that the morphological circumscriptions of Paepalanthus s.str. and of most of the other 11 segregate genera lack coherence. The majority of characters used as potential synapomorphies or in diagnoses are not sufficient to support the genera because they conflict with or do not represent the morphology of all the included species. The information regarding inflorescence branching patterns and seed coat are interpreted ambiguously or represent preliminary results, and some characters are known for only a limited number of species. Inflorescences are difficult to interpret in herbarium specimens, and the seed coat mostly requires SEM analysis for proper visualization, thus hindering identification. On the other hand, Paepalanthus s.l. can be identified by a combination of floral characters, as can the remaining genera of the family. We therefore endorse the recognition of Paepalanthus s.l. as a single, nomenclaturally stable, and monophyletic entity. This is the best‐fitting solution to reflect both evolutionary and morphological aspects of this recently diversified lineage. Finally, we provide a new identification key for the 7 genera of the Eriocaulaceae, characterizing Paepalanthus s.l. by floral characters that can be observed in any flowering specimen.","PeriodicalId":49448,"journal":{"name":"Taxon","volume":"189 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141577562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
