Platycodon grandiflorus has long been used for its medicinal, culinary and ornamental properties. With increasing market demand and the depletion of wild resources, understanding the distribution and factors affecting its habitat suitability is crucial for its conservation and sustainable utilization. This study aims to predict the suitable habitat for P. grandiflorus in China considering current and future climate scenarios. The MaxEnt model, with an AUC value of 0.846, demonstrated good predictive ability for the current and future distribution of P. grandiflorus. It also identified the central, eastern, and southern regions as suitable habitats, with the critical environmental factors being precipitation, temperature, and elevation. Future scenarios under both SSP126 and SSP585 projections indicate an increase in suitable habitats, particularly in northeastern and central China, albeit with a shift in the distribution center towards the northeast by 2041–2060 and 2081–2100 under different scenarios. P. grandiflorus' distribution is significantly influenced by environmental factors, with precipitation and temperature being pivotal. Taken together, our study predicts an expansion of suitable habitats under future climate scenarios and the northward shift in the distribution center underlines the impact of global warming on the distribution of P. grandiflorus. The findings are crucial for the conservation, effective utilization, and strategic planning for the cultivation of P. grandiflorus in the face of climate change.

We analysed ground vegetation in 250 plots in 2018 in the old‐growth Picea abies‐dominated forest Säby Västerskog, south‐east Sweden as a follow‐up of studies in 1946 and 1998 with the same layout of plots. The vegetation changes were not clearly directional: the species composition in 2018 was intermediate between that of 1946 and 1998, whereas in 1998 species richness was higher and with the unique presence of a number of species indicating small‐scale disturbances. Vaccinium myrtillus increased in cover since 1946 and Avenella flexuosa decreased. This goes against regional trends that have been attributed to nitrogen deposition. Regional changes are overshadowed by local dynamics.

The taxonomic history, nomenclature and application of one of the oldest species names in Pilosella are reviewed. Hieraciumfloribundum originally included a hybrid swarm with the participation of Pilosella lactucella, P. caespitosa, P. praealta and partly P. officinarum, and was interpreted either as a binary (P. lactucella × P. caespitosa) or triple (P. lactucella × P. caespitosa × P. praealta) hybrid. The original material of H. floribundum from Silesia, Poland includes plants of the triple hybrid which are designated as its lectotype in conformity with the usage of the species name that has been predominant during its history. The lectotype belongs to a morphotype in which the diagnostic characters of P. lactucella are dominant, and which is not typical of northern and eastern Europe. A further lectotype from the same hybrid complex is designated for H. floribundum var. subcymosum.
本文回顾了 Pilosella 最古老的种名之一的分类历史、命名和应用。Hieracium floribundum 最初包括一个杂交群，其中有 Pilosella lactucella、P. caespitosa、P. praealta 和部分 P. officinarum 的参与，被解释为二元（P. lactucella × P. caespitosa）或三元（P. lactucella × P. caespitosa × P. praealta）杂交种。来自波兰西里西亚的 H. floribundum 原始材料中包括三系杂交种的植株，根据种名在其历史上的主要用法，将其指定为标准模式。该模式标本属于一种形态类型，其中 P. lactucella 的诊断特征占主导地位，这在北欧和东欧并不典型。来自同一杂交复合体的另一个标本被指定为 H. floribundum var.

A new species of Pseudosperma is described based on collections recently made in Benin in West Africa. Pseudosperma brunneopilosum sp. nov. occurs in forests dominated by ectomycorrhizal Fabaceae Isoberlinia and Phyllanthaceae Uapaca trees. Phylogenetic analysis of combined ITS‐LSU‐RPB2‐TEF1 gene regions shows that P. brunneopilosum is unrelated and distinct from several recently described species of Pseudosperma also from West Africa. Complete descriptions and illustrations, including photographs and line drawings are presented.

This study is based on the identification of the novel species Leucoagaricus persicus from Swat, Khyber Pakhtunkhwa, Pakistan. The species is characterized by convex to broadly convex pileus with a dark reddish‐brown umbo and orangish‐red fibrils on white context. The basidiospores are ellipsoid to elongate, amygdaliform to ovoid (10.2–12.0 × 6.6–7.5 µm), and there are variably shaped cheilocystidia and pileipellis hyphae without clamp connections forming an intricate trichoderm. Morphological and molecular phylogenetic data based on ITS and LSU region of nrDNA separate L. persicus from all other known species in Leucoagaricus.

Violafuscopurpurea (Violaceae), a new species from Karst landform of Chongqing in China, is described and illustrated. The new species is most similar to V. fukienensis, but can be distinguished by nearly glabrous, shiny, adaxially purple blades (vs pubescent, adaxially green blades), brown seeds with conspicuous tubercles (versus yellow seeds with smooth surface), and hook‐like nectaries (versus triangular nectaries), as well as by general habit. Our phylogenetic analysis, based on ITS sequences, confirms that the new species belongs to V. subsect. Rostratae, and is most closely related to V. fukienensis in the phylogeny.

A new subalpine species of Bufonia sect. Longipedicellata from the Zagros Mountains in west Iran is described and illustrated here. It colonizes mountain slopes with gravelly, stony, and scree substrates in one locality of Chaharmahal and Bakhtiari province, preferably with a western and north‐west orientation, at elevations between 2700 and 3100 m a.s.l. The new species, B. darvishii, is diagnosed against the morphologically similar B. macrocarpa. The two species share similarities such as filiform and long pedicels, a lax panicle‐cyme inflorescence, distribution pattern of trichomes, and long peduncles. However, the new species stands out with semi‐shrub life form, its greater height, retention of the previous year's stems, cymes bearing more flowers, orbicular petals, larger petals, a broadly ovate ovary, larger sepals with more pronounced nervation, shorter pedicels, larger flowers, etc. Bufonia darvishii is proposed to be Critically Endangered (CR) following the guidelines of the IUCN.

The new species, <jats:italic>B. darvishii</jats:italic>, is diagnosed against the morphologically similar <jats:italic>B. macrocarpa</jats:italic>. The two species share similarities such as filiform and long pedicels, a lax panicle‐cyme inflorescence, distribution pattern of trichomes, and long peduncles. However, the new species stands out with semi‐shrub life form, its greater height, retention of the previous year's stems, cymes bearing more flowers, orbicular petals, larger petals, a broadly ovate ovary, larger sepals with more pronounced nervation, shorter pedicels, larger flowers, etc. <jats:italic>Bufonia darvishii</jats:italic> is proposed to be Critically Endangered (CR) following the guidelines of the IUCN.","PeriodicalId":54716,"journal":{"name":"Nordic Journal of Botany","volume":"67 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141771695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
