There is no known original material linked to the name Gentiana meyeniana Griseb. [≡ Gentianella meyeniana (Griseb.) Fabris]. The uncertainty about the correct application of the name, the discrepancies among the published descriptions of the species, and the high affinity in descriptive morphology with the type material of the name Gentianella boliviana support a proposal that the name Gentiana meyeniana be rejected, since the specific epithet of the latter name has priority over boliviana.

Melanin is a heterogenic polymer of phenolic or indolic nature, possessing a broad spectrum of biological activities including radio- and photoprotective, antioxidant, chemoprotective, antiviral, antimicrobial, cytotoxic and immunostimulating activity. Based on these characteristics, natural melanin holds significant potential for applications in the fields of biomedicine, nanotechnology and materials science. Along with that, the exploration of organisms producing natural melanin remains relevant and filamentous fungi with their exceptional metabolic versatility are promising sources of these pigments. Wood-inhabiting fungi in particular are known to produce specific types of melanin as secondary metabolites. This study aimed to quantify and characterise melanin in the mycelium of various strains of Xylaria polymorpha, a common representative of wood-inhabiting fungi. As a result, among the ten studied strains of X. polymorpha, the highest melanin synthesis productivity was observed in the strain IBK 2737, reaching 180.32 ± 4.16 mg/l, while the lowest was recorded in the strain IBK 2723 at 5.17 ± 0.36 mg/l. This investigation highlights that X. polymorpha strains from the IBK Culture Collection show promise as a valuable source of natural melanin.

The article is devoted to syntaxonomy and synphytoindication of steppe vegetation in Mykhailivska Tsilyna Nature Reserve (Sumy Region). Based on phytosociological materials collected in 2021–2022 and literature data, changes of steppe vegetation in the reserve over the past ten years have been analyzed. The plant communities of the class Festuco-Brometea were identified as two subassociations and two variants in three associations, belonging to one alliance and one order. The article provides characteristics of the syntaxa, their ecological requirements, synphytoindication indexes, and results of DCA-ordination of the obtained indexes of ecological factors. It has been found that the main ecological gradients affecting ecological and territorial differentiation of the syntaxa are the soil humidity, nitrogen content in soil, soil aeration, and total salt regime. During the study, an increasing mesophytization of the steppe vegetation was observed, caused by the absence of mowing on the territories that formerly were under the constant mowing regime.

False flax (Camelina sativa, Brassicaceae), an emerging biofuel oilseed crop, demonstrates a very limited genetic diversity, which conditioned the high scientific interest to its closest wild relative, C. microcarpa, which is suitable for interspecific hybridization with C. sativa. However, C. microcarpa (as currently understood) is a genetically non-uniform and morphologically variable species that consists of several distinct ribotypes and cytotypes with varying ploidy levels. Little-pod false flax diversity remains understudied in Ukraine, despite the country is one of genetic diversity hotspots of this species. Therefore, in the present study we aimed to clarify the distribution patterns of C. microcarpa and its various infraspecific forms in Ukraine, based on the collections of the National Herbarium of Ukraine (KW). In particular, it has been demonstrated that C. microcarpa occurs at present over the almost whole territory of Ukraine and is represented by two distinct hexaploid cytotypes, as well as by two Western-type ribotypes (W1 and W2).The obtained results clarify the actual distribution range of C. microcarpa in Ukraine and for the first time allows to delineate its various forms there, which in the future can be used for further studies of the population structure of representatives of C. microcarpa in Ukraine.
假亚麻（Camelina sativa，十字花科）是一种新兴的生物燃料油籽作物，其遗传多样性非常有限，因此科学界对其最亲近的野生近缘植物 C. microcarpa 非常感兴趣，因为它适合与 C. sativa 进行种间杂交。然而，C. microcarpa（根据目前的了解）是一个遗传不统一、形态多变的物种，由几个不同的核型和细胞型组成，倍性水平各不相同。尽管乌克兰是小杆假亚麻遗传多样性的热点地区之一，但对该国小杆假亚麻多样性的研究仍然不足。因此，在本研究中，我们以乌克兰国家标本馆（KW）的藏品为基础，旨在阐明小杆假亚麻（C. microcarpa）及其各种种下形态在乌克兰的分布模式。所获得的结果澄清了 C. microcarpa 在乌克兰的实际分布范围，并首次对其在乌克兰的各种形态进行了划分，今后可用于进一步研究 C. microcarpa 在乌克兰的种群结构。

In Europe, Wolffia globosa was first recorded in 2002 in the RF, and not in Bulgaria, as it was previously believed. Over the past 20 years, the species has expanded its secondary range. As of 2023, it is known from seven European countries. In Ukraine, W. globosa was first found in 2023 in two localities in Zhytomyr Region (Zhytomyr Polissia). The plant communities with W. globosa in Ukraine belong to the association Lemno-Spirodeletum polyrhizae of the alliance Lemnion minoris of the class Lemnetea. In the reported localities W. globosa occurs in eutrophic stagnant waterbodies with depths of 0.2–0.5 m and weakly flowing waterbodies with depths of 1.2–1.5 m; silty bottom is covered by a silt layer 5–20 cm thick, lighting is full. It is suggested that due to the observed climate warming, further migrations of W. globosa to other regions of Ukraine are possible.

Diphasiastrum tristachyum (Lycopodiaceae) is a rare species of the Ukrainian flora, listed in the Red Data Book of Ukraine. In our country it occurs mainly in Central (Zhytomyr) Polissya. Two localities only have been recorded in Volhynian Polissya. In the literature sources, there is no information about distribution of D. tristachyum in Kyiv Polissya. However, back in 1899, the species was collected near the town of Boyarka (KWU0001665). Although correctly identified, this specimen has not been previously included in distribution data. We report a new locality of D. tristachyum from pine forest in Lub'yanka Forestry in Bucha District, Kyiv Region. In the Podolian Upland, an isolated local population of D. tristachyum was found in a karst sinkhole near Hutysko village, Ternopil Region. A list of all known localities of D. tristachyum in Ukraine and data on the current state of its populations in the newly reported localities are provided. It is proposed to establish a botanical reserve in Lub'yanka Forestry.
Diphasiastrum tristachyum（茄属）是乌克兰植物区系中的稀有物种，已被列入《乌克兰红色数据手册》。在我国，它主要分布在波利西亚中部（日托米尔）。仅在伏尔加波利西亚有两个地方有记录。在文献资料中，没有关于 D. tristachyum 在基辅波利西亚分布的信息。不过，早在 1899 年，该物种就在波亚尔卡镇附近被采集到（KWU0001665）。虽然该标本已被正确识别，但此前并未被纳入分布数据中。我们报告了基辅地区布查区卢布扬卡林场松树林中的 D. tristachyum 新产地。在波多里亚高原地区，特尔诺皮尔州 Hutysko 村附近的岩溶天坑中发现了一个孤立的 D. tristachyum 当地种群。本报告提供了乌克兰所有已知 D. tristachyum 分布地点的清单，以及新报告地点的 D. tristachyum 种群现状数据。建议在卢布扬卡林场建立一个植物保护区。

The impact of Quercus rubra on the plant diversity of native forests of Ukraine has been investigated. The plant communities of artificial plantations dominated by northern red oak have such general features as poor species composition, with projective coverage values of other species not exceeding 5%, and a simplified vertical structure of the tree layers. In natural forest plant communities with the participation of Q. rubra, there are no rare and typical nemoral dominant species, which results in disruption of consortial relations in ecosystems. Such changes are due to the biological and ecological peculiarities of this species, in particular, its dense crown, abundant biomass of leaves, which reduces lighting, and allelopathic properties; all those factors affect the physical and chemical characteristics of biotopes. Quercus rubra artificial plantations are more adaptive to changes of natural conditions and are able to withstand harsher winters and lack of precipitation. The ecological amplitude of this species is wide, and even with an increase in the average annual temperature by 3 °C most of the ecological indicators do not go beyond the optimum zone of the species, except for the soil moisture and thermal regime. The amplitudes of main indicators of ecological factors of temperate forests and Q. rubra artificial plantations overlap. The dominance of Q. rubra reduces the quality of ecosystem services of native forests. The high competitive advantages of Q. rubra are the reason for the impossibility of natural restoration of the typical broad-leaved or coniferous forests on those land plots where they were replaced by artificial plantations of northern red oak or its tree layers were formed as the results of the spontaneous distribution of this species. In the successions, the communities with the participation of northern red oak are potentially able to replace the native forest phytocoenoses.

Our herbarium inventory revealed that the collection of specimens of the genus Artemisia (Asteraceae) in the memorial collection of W.S.J.G. Besser (KW-BESS) at the National Herbarium of Ukraine (KW) contains at least 1186 herbarium sheets. The collection of specimens of Artemisia is stored in folders Nos. 234–249 of the Besser herbarium. Each folder contains individual paper folders (here termed taxon covers). In total, there are 217 individual taxon folders. Our analysis of protologues and herbarium labels demonstrated that the KW-BESS collection contains types and/or other original specimens in 118 taxon folders, but much more actual types of species-rank and infraspecific names. Additional analysis of their possible type status is needed for specimens in 28 taxon folders. The KW-BESS collection contains authentic and historical specimens of such famous researchers and collectors of the 19th century as A. Bunge, L.K.A. Chamisso, A.P. de Candolle, D. Douglas, J.F.G. Eschscholtz, F.E.L. Fischer, J.É. Gay, A. Gray, J.D. Hooker, V.V. Jacquemont, G.S. Karelin and I.P. Kirilov, K.F. Ledebour, A.F. Marschall von Bieberstein, C.A. Meyer, T. Nuttall, J.D. Prescott, Ch. Steven, N.S. Turczaninow, N. Wallich, etc. We present and discuss here some examples of labels written by Besser and several other famous botanists. Our preliminary assessment of this globally important collection established the foundations for further nomenclatural and taxonomic studies of Artemisia, in particular, those based on historical specimens at KW.
我们的标本馆目录显示，乌克兰国家标本馆（KW）的贝瑟（W.S.J.G. Besser）纪念收藏（KW-BESS）中的蒿属（菊科）标本收藏至少包含 1186 张标本纸。收藏的青蒿标本保存在贝瑟标本馆第 234-249 号文件夹中。每个文件夹都包含单独的纸质文件夹（此处称为分类群封面）。总共有 217 个分类群文件夹。我们对原型和标本馆标签的分析表明，KW-BESS 藏品中有 118 个分类群文件夹中的类型和/或其他原始标本，但物种等级和种下名称的实际类型要多得多。对于 28 个分类文件夹中的标本，还需要对其可能的类型地位进行进一步分析。KW-BESS 藏品包含 19 世纪著名研究者和收藏家的真实历史标本，如 A. Bunge、L.K.A. Chamisso、A.P. de Candolle、D. Douglas、J.F.G. Eschscholtz、F.E.L. Fischer、J.É.Gay, A. Gray, J.D. Hooker, V.V. Jacquemont, G.S. Karelin and I.P. Kirilov, K.F. Ledebour, A.F. Marschall von Bieberstein, C.A. Meyer, T. Nuttall, J.D. Prescott, Ch. Steven, N.S. Turczaninow, N. Wallich 等。我们在此介绍并讨论贝瑟和其他几位著名植物学家撰写的标签范例。我们对这一全球重要收藏的初步评估为进一步的蒿属植物命名和分类研究奠定了基础，特别是那些基于 KW 历史标本的研究。

Besser (KW-BESS) at the National Herbarium of Ukraine (KW) contains at least 1186 herbarium sheets. The collection of specimens of Artemisia is stored in folders Nos. 234–249 of the Besser herbarium. Each folder contains individual paper folders (here termed taxon covers). In total, there are 217 individual taxon folders. Our analysis of protologues and herbarium labels demonstrated that the KW-BESS collection contains types and/or other original specimens in 118 taxon folders, but much more actual types of species-rank and infraspecific names. Additional analysis of their possible type status is needed for specimens in 28 taxon folders. The KW-BESS collection contains authentic and historical specimens of such famous researchers and collectors of the 19th century as A. Bunge, L.K.A. Chamisso, A.P. de Candolle, D. Douglas, J.F.G. Eschscholtz, F.E.L. Fischer, J.É. Gay, A. Gray, J.D. Hooker, V.V. Jacquemont, G.S. Karelin and I.P. Kirilov, K.F. Ledebour, A.F. Marschall von Bieberstein, C.A. Meyer, T. Nuttall, J.D. Prescott, Ch. Steven, N.S. Turczaninow, N. Wallich, etc. We present and discuss here some examples of labels written by Besser and several other famous botanists. Our preliminary assessment of this globally important collection established the foundations for further nomenclatural and taxonomic studies of Artemisia, in particular, those based on historical specimens at KW.","PeriodicalId":52835,"journal":{"name":"Ukrainian Botanical Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138949834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
