Yukinobu Kuwahara has described several Metzgeria taxa from Asia. However, most of these taxa have remained a mystery because their type specimens cannot be located in the herbarium where they were supposedly deposited in. This makes it difficult to effectively review the taxonomy of these taxa and Kuwahara's conception of the genus. In the present study, the unavailability of these types in NICH was formally investigated and addressed. These taxa are typified on the basis of newly located types or ordinary specimens identified by Kuwahara himself.

Defining species boundaries within plant groups distributed along wide elevational and geographic gradients may lead to unstable taxonomic delimitations using morphological data only. 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.
在分布于海拔和地理梯度较宽的植物群落中界定物种边界时，仅使用形态学数据可能会导致不稳定的分类界定。在分类上极具挑战性的石竹属中，我们通过综合方法测试了亚平宁半岛中南部山峰上特有的假定物种 D. brachycalyx 与广泛分布于地中海中部的 D. virgineus 的分类价值。我们测量了 25 个种群 452 个个体的 30 个形态特征，并利用 ddRAD-seq 技术获得了 36 个种群 394 个个体的 3202 个单核苷酸多态性。为了进行气候生态位比较，我们建立了一个包含 348 个出现点的数据集。通过比较形态计量学、遗传学和气候生态位数据，我们发现D. brachycalyx不能被视为一个独立的物种。这两个物种之间的形态学分离是可以检测到的，但高海拔地区的D. virgineus种群与D. Brachycalyx相似。遗传分析表明，无论分类学归属如何，D. brachycalyx 和 D. virgineus 种群的遗传结构主要是由距离隔离形成的。这两个物种的气候生态位是重叠的，而生态位差异只是由于其分布区的气候条件不同造成的。因此，多种证据都不支持将 D. brachycalyx 与 D. virgineus 区分开来，前者应被视为后者的异型异名。

Despite remarkable progress in taxonomy within Caryophyllaceae and the tribe Caryophylleae gained from molecular phylogenetic evidence, there are some unresolved issues on generic boundaries in this tribe mainly due to poor sampling of some crucial taxa. 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.

Caryodaphnopsis is a small genus of the Lauraceae family with disjunct distribution in tropical Asia and tropical America. 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.

We here evaluate the conflicting recent splitter and lumper strategies concerning the generic classification system of the Eriocaulaceae, and whether Paepalanthus s.str. and its proposed segregate genera are morphologically recognizable. 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.
