Background: The first checklist for the Soutpansberg was published in 1946, and the second list was compiled by the author in 2006 as part of his doctoral thesis. Currently, there is a need for an updated account of the biodiversity of the Soutpansberg Centre of Endemism and Diversity for conservation planning in the Vhembe Biosphere Reserve, within which the Soutpansberg is the principle geomorphological feature.Objectives: To present an updated list of vascular plants recorded for the Soutpansberg.Method: The list was compiled from various sources including literature reviews, herbarium specimens, herbarium databases and personal observations.Results: This article presents the most geographically accurate and taxonomically updated list of the indigenous vascular flora of the Soutpansberg, the northernmost mountain range of South Africa. Altogether 2443 taxa are recorded belonging to 922 genera in 187 families and 64 orders.Conclusion: The list presented in this article confirms the status of the Soutpansberg as a centre of floristic diversity in southern Africa. Notable is the higher-order diversity of the flora. It is likely that both future surveys and reviews of herbarium collections will add new taxa to the current total.

Baikalsky State Nature Biosphere Reserve is situated in the central part of the Khamar-Daban Range (Southern Baikal, Siberia), in three administrative districts of Republic of Buryatia (i.e. Kabansky District, Dzhidinsky District and Selenginsky District), Russia. In general, this territory has been relatively well studied by botanists, but until now there was no detailed information about the flora of the Reserve with precise geographic localities. Moreover, some records in the Baikalsky Reserve's flora were published without references to documenting herbarium specimens. The dataset contains 39,238 unique occurrences of 875 taxa (854 species, 14 subspecies, five varieties and two species aggregates) from the Baikalsky Reserve and its buffer zone. All the data were acquired during the field studies by the author in 2009–2021, when 152 taxa (17.3% of all the taxa included into the dataset) were first recorded by the author from the study area. Herbarium vouchers are preserved in the Moscow University Herbarium (MW). This dataset is the first attempt at creating a database of vascular plants of the Baikalsky Reserve and its buffer zone, based on modern research. These data will provide the background for the updated check-list of the Baikalsky Reserve's flora.

The present-day demand for digital availability of distributional data in biodiversity studies requires a special effort in assembling and editing the data otherwise scattered in paper literature and herbarium collections, which can be poorly accessible or little understood to present-day users and especially automatic data processors. Although the vascular plants of Murmansk Region (northern part of European Russia) are well studied and represented in publications, the accessibility of this knowledge is highly insufficient. The most widely known source is the Flora of Murmansk Region (published in 1953–1966), which remains in use because of its high original quality, detailed elaboration and completeness. We consider digitising this source to be of primary importance in biodiversity studies in the Arctic Region because of its point occurrence maps, which were based on the comprehensive inventory of contemporary herbarium collections. We have compiled a dataset based on 554 printed point occurrence maps of species distributions published in the Flora of Murmansk Region, which includes 25,555 records of georeferenced plant occurrences that belong to 1,073 species and 5 hybrids. The occurrences are ultimately based on herbarium specimens kept at KPABG and LE, which were collected during 1837–1965. We estimate that these specimens represent ca. 60% of the current global herbarium holdings originated from Murmansk Region; this means that the dataset gives a fair representation of the regional flora.

AbstractThe paper presents a brief biography of Professor Povilas Snarskis, and discusses the importance of his work for Lithuania. After defending PhD at Vytautas Magus University, P. Snarskis was able to collect invaluable data on the Lithuanian floristic diversity and distribution. He actively participated in the development of the Lithuanian higher education. In 1947, he became a professor and taught botany at Vilnius University and Vilnius Pedagogical Institute. During his professional career, P. Snarskis has published about 60 research and popular science works. He was a co-author of Flora of Lithuanian SSR and his three guides to native vascular plants still have their high value. The number of Snarskis’ herbarium specimens deposited at Vilnius University Herbarium (WI) and the Nature Research Centre, Institute of Botany Herbarium (BILAS) exceeds 20.000. P. Snarskis was an innovator, who used his logic and creativity, and constructed guidelines to achieve his goals in difficult historical times.

The Status

Historically there has been confusion over the status and identification of Callitriche species in South Africa. Review of herbarium specimens and fieldwork have enabled confirmation of the presence of C. deflexa as a naturalised species in this country and confirmed that C. compressa and specimens named as C. bolusii are conspecific. Field surveys showed that C. compressa still occurs in the areas from which most historic collections were made with no evidence of a decline, it is widespread but local in Kwa-Zulu Natal and Eastern Cape Provinces and extends into eastern Western Cape Province. However because it is known from only five widely scattered sites, it is classed as Vulnerable under the IUCN Red List. We also typify here the names C. compressa and C. deflexa.

According to the data in Index Herbariorum as of 1 December 2020, there are 3426 active herbaria in the world, containing 396,204,891 specimens and 124 herbaria in Russia with more than 16,175,000 specimens. The Central Siberian Botanical Garden of the Siberian Branch of the Russian Academy of Sciences (CSBG SB RAS, Novosibirsk), founded in 1946, historically has two herbarium collections (NS and NSK). Currently these collections contain about 800,000 herbarium specimens comprising vascular plants, mosses, lichens and fungi gathered from all over the world. Digitisation of the NSK type specimens of vascular plants began in 2014 by using the special scanner Herbscan. In 2018, we started digitisation of the NS and NSK collections by using ObjectScan 1600. Pteridophytes (ferns, lycophytes and their extinct free-sporing relatives) are a diverse group of plants that today comprises approximately 12,900 species and plays a major role in terrestrial ecosystems. All herbarium specimens of ferns, collected over 170 years between 1851 and 2021 and stored in the NS and NSK collections, were digitised in 2021, placed at the CSBG SB RAS digital Herbarium (http://herb.csbg.nsc.ru:8081) and published through GBIF. Twenty families of Polypodiopsida, but not Equisetaceae, were included in this dataset. Family Ophioglossaceae was digitised and published in GBIF as a separate dataset. By August 2021, more than 62,600 specimens with good quality images and fully-captured label transcriptions had been placed at CSBG SB RAS Digital Herbarium. A total of 7,758 records of fern occurrences of 363 taxa in the world with 92% geolocations including 5100 records from Russia with 98.7% geolocations that are new for GBIF.org in 2021 were entered. In the dataset specimens from 43 countries of Europe, Asia, America, Africa and Australia (Oceania), 89% of them from Russia, are presented.

The Status

The six major mountain ranges in South Africa support critically important ecosystem services—notably water production—and are rich in biodiversity and endemism. These mountains are threatened by detrimental land uses, unsustainable use of natural resources, climate change, and invasive alien plants. Invasive alien plants pose substantial and rapidly increasing problems in mountainous areas worldwide. However, little is known about the extent of plant invasions in the mountains of South Africa. This study assessed the status of alien plants in South African mountains by determining sampling efforts, species compositions and abundances across the six ranges in lower-and higher-elevation areas. Species occurrence records were obtained from three databases that used various approaches (roadside surveys, citizen science observations, focused botanical surveys). Most mountain ranges were found to be undersampled, and species composition assessments were only possible for two ranges. The majority of abundant alien plants in both the lower- and higher-elevation areas were species with broad ecological tolerances and characterised by long distance seed dispersal. These prevalent species were mostly woody plants—particularly tree species in the genera Acacia, Pinus, and Prosopis—that are contributing to the trend of woody plant encroachment across South African mountains. We suggest improved mountain-specific surveys to create a database which could be used to develop management strategies appropriate for each mountain range.

Background: The taxonomic and phylogenetic status of Colpoon, Osyris and Rhoiacarpos (Santalaceae, Osyrideae) is reviewed.Objectives: To resolve confusion regarding whether Colpoon is deserving of generic status separate from Osyris.Methods: Existing morphological information was examined for the three genera as well as previously published molecular phylogenies.Results: From both morphological and phylogenetic perspectives, Colpoon is distinct from Osyris. The status of Rhoiacarpos was not contentious and this genus is also easily differentiated from the other two genera in Osyrideae.Conclusions: Colpoon and Osyris are not congeneric; therefore, floras, databases and herbarium collections should recognise these as distinct taxa.

The Central Siberian Botanical Garden of the Siberian Branch of the Russian Academy of Sciences (CSBG SB RAS) is the largest botanical institution in the Asian part of Russia. Founded in 1946, CSBG SB RAS is historically a consortium of two herbarium collections with their own acronyms (NS and NSK) and registration in the Index Herbariorum (Thiers 2020). At present the NS+NSK collections contain about 800,000 herbarium specimens comprising vascular plants (680,000), mosses (25,000), lichens (80,000) and fungi (15,000) gathered, not only in Siberia, but also in the European part of Russia and other parts of the Eurasian and American continents. CSBG SB RAS has the third largest collection in Russia after the Komarov Botanical Institute of RAS (LE) and Moscow State University (MW) collections. The dataset consists of 5,384 records of digitised herbarium specimens of vascular plants belonging to 111 families, collected since the 19th century in 54 administrative regions from the European part of Russia and kept in NS+NSK collections. Herbarium specimens were digitised using two special scanners, both ObjectScan 1600, according to international standards, at 600 dpi, with a barcode, 24-colour scale and spatial scale bar and placed into the CSBG SB RAS Digital Herbarium. For each specimen, the species name, locality, collection date, collector, ecology and revision label are recorded. More than 94% of the records have coordinates that fall within the area of European Russia, west of the Ural Mountains. A total of 5,384 records of vascular plant occurrences with 94.8% geolocations in the territory of the European Russia West of the Ural Mountains were entered.

Special Relevance

The value of distinguishing between plant species regarded as ‘native’ and ‘alien’ has special relevance in the island continent of Australia, where European settlement was a springboard for human-assisted plant dispersal. The year of European settlement is proposed here as providing a distinction between a ‘native’ and ‘naturalised’ flora and is applied for the entire Australian flora of vascular plants. Herbarium collections and ecological criteria were employed to determine the status of 168 species of ambiguous origin. The date of 1788 proved to be a relatively straightforward criterion to assign native and naturalised status and the origin of only 27 plant species remains ambiguous. The dispersal of plants between continents is an ongoing process but European settlement of the Australian continent represents a very sharp biogeographic event for the Australian flora and provides a straightforward criterion for determining the ‘naturalised’ species.

The article provides information on the distribution of 38 species of vascular plants in the Kemerovo region that were not reflected in the second edition of the regional Red book. These data were obtained in the processing of herbarium collections compiled in 1969 – 2012 by teaching staff and students of the Kemerovo State University. As a result, 96 unknown localities of protected plants were revealed. More than 2/3 of herbarium specimens clarify the distribution of species in the administrative regions listed in the regional Red book, and the rest were collected outside. Only a small portion of the finds were confirmed by later compilations, data on the remaining locations do not exist, population monitoring in these localities was nit conducted. In this regard, to use the received information in a subsequent edition of the Kemerovo region Red book, it is necessary to conduct additional exploration of the territories, clarifying the fact of preservation of the populations and assessment of their condition.
