Plants are a valuable source of different folk and modern medicines. Therefore, correctly identifying the plant species is a prerequisite for using them in the health care system. Euphorbia species are of great medicinal importance but are difficult to distinguish due to the occurrence of ecotypes and a high degree of polymorphism within the species. Therefore, the present study was planned to explore the extent of variations in morphological characters among three Euphorbia species, namely, Euphorbia prostrata Aiton, Euphorbia serpens Kunth and Euphorbia thymifolia L. The edaphic ecotypes red and green forms of Euphorbia prostrata growing separately or adjacent to each other were reported during field surveys. To ensure identification accuracy, illustrated online key was prepared as a supportive tool for the traditional key.

Neotinea ustulata (Orchidaceae) is a rapidly declining species throughout much of its range and is classified as critically endangered in Lithuania. Most of the historical occurrences of the species were concentrated in northwestern Lithuania, while the largest extant population was in the southern part of the country. In July 2022, a new population of Neotinea ustulata was discovered in an urbanised habitat in Šiauliai in northern Lithuania. A total of 84 individuals of this species were recorded in the population. In the southern part of Lithuania (Varėna distr.), the studied population comprised 86 individuals in 2002 and had decreased to 64 individuals by 2022. The total currently known population of the species in the country consists of about 150 individuals and remains critically endangered. The individuals of Neotinea ustulata studied in Šiauliai were significantly lower and had shorter inflorescences than the plants studied in Varėna district in 2002 and 2022. Since the population of Neotinea ustulata in Šiauliai is in an urbanised area, its conservation poses a significant challenge, making it difficult to make long-term predictions on the development of the population. Therefore, it is essential to continue searching for populations of Neotinea ustulata in the country, perform detailed studies on the plants’ reproductive potential, and properly organise the management and protection of extant populations and their habitats.

The genus Lagenaria (Cucurbitaceae) members are underutilised, neglected and on the verge of being threatened to extinction. An investigation of their reproductive biology will serve as the basis for effective strategic planning towards their conservation. The plant materials used for this study were collected from Osun, Ekiti and Niger States in Nigeria. Reproductive parameters, including seed germination, phenology and pollination mechanism, were documented. The highest seed germination rate was observed in the accession of Lagenaria siceraria from Ekiti Bowl. The male flowers appeared first, followed by female flowers’ emergence 14–28 days later, on the secondary shoots. The female flowers of each accession had unique inferior ovary shapes, which developed into different fruit shapes with distinct seed morphology. This study showed that the members of Lagenaria performed better as climbers than as trailers, and the number of fruits produced per accession depends on the size or weight of the fruit. Chrysomelidae and Coryna apicicornis beetles were the primary pollinators observed. Furthermore, the pollens were predominantly monad, spheroidal and tricolporate, and pollen stainability ranged between 81% and 91% in all the accessions studied. Therefore, the fruit and seed morphology were diagnostic for each accession, and the flowers were pollinated mainly by beetles

Laphangium luteoalbum (Asteraceae) is a widely distributed species native to Eurasia; however, it is rare or endangered in some regions of Europe and included into the lists of protected species. In Lithuania, Laphangium luteoalbum was recorded in the southern part of the country, mainly along the banks of the Nemunas River in the 20th century. In contrast, it was found only in the 19th century in the western part of the country. During the research in Curonian Spit National Park (Neringa, western Lithuania), a relatively large species population was found in the transition zone between the dune grassland and wet dune slack habitats. The total population in 2020 consisted of about 500 individuals distributed over an area of about 310 m2. We assume that the seeds of this wind-dispersed plant may have been transferred from other regions of Europe by the wind. However, it cannot be excluded that the plants found are descendants of populations previously recorded in the country. The species is most threatened by the loss of wet, open sandy habitats due to eutrophication of water bodies and subsequent changes in bank vegetation. Laphangium luteoalbum was classified as data deficient (DD) in the last assessment according to the IUCN criteria. Still, a reassessment based on the current data indicates that the species should be considered critically endangered (CR) in Lithuania.
黄芪是原产于欧亚大陆的一种分布广泛的植物;然而，它在欧洲的一些地区是罕见或濒危的，并被列入保护物种名单。在立陶宛，20世纪在该国南部主要沿Nemunas河沿岸记录了Laphangium luteoalbum。相比之下，它只在19世纪在该国西部地区被发现。在立陶宛西部尼林加库尔斯沙嘴国家公园(Curonian Spit National Park, Neringa, western Lithuania)的研究中，在沙丘草地和湿沙丘松弛生境之间的过渡地带发现了相对较大的物种种群。2020年的种群总数约为500只，分布在约310平方米的面积上。我们认为这种风散植物的种子可能是由风从欧洲其他地区传播过来的。然而，不能排除发现的植物是该国先前记录的种群的后代。由于水体富营养化和随后的河岸植被变化，该物种受到的最大威胁是潮湿、开阔的沙质栖息地的丧失。根据国际自然保护联盟(IUCN)的标准，在上次评估中，黄芪被列为数据不足(DD)。尽管如此，基于当前数据的重新评估表明，立陶宛应该将该物种视为极度濒危物种(CR)。

Basella alba is an important, underutilised vegetable rich in vitamins and consumed in many parts of the world. However, the reproductive biology of this species is insufficiently known; therefore, this study was performed aiming to fill this knowledge gap. Although green-stemmed and red-stemmed Basella alba share a lot of reproductive attributes in common, the obtained results showed differences in their flower bud apex colour, anther colour, spike colour, days to 50% flowering, plant height at flower bud initiation and the mean number of flowers per spike. In both forms, the floral attributes favoured self-pollination. However, the possibility of cross-pollination among them due to the activities of pollinators such as ants, moths, butterflies and bees suggests a mixed mating system. Furthermore, both forms attained sexual maturity at varying periods, thus indicating the existence of a temporal prezygotic barrier between them and limiting the chances of their hybridisation. They could also be responsible for the ability to remain in their distinct forms even when they exist together in the same habitat.

The research results on bryophyte diversity in two special areas of conservation (Environs of Lakes Žalieji and Ežerėliai Complex ) included into the Natura 2000 network and occurring on the outskirts of Vilnius are presented. The study aimed to ascertain bryophyte diversity at the studied sites. In addition, the conservation status of habitats protected under the European Union Habitats Directive in terms of bryophyte species they contain was evaluated. The research was carried out in 2019–2020 and 2022 and covered all habitat types and substrata in the territories. A total of 110 bryophyte species (11 liverworts and 99 mosses) were recorded in both studied areas. About 70% of bryophytes were recorded in one of the areas. Among 13 habitats protected under the Habitats Directive, bryophyte diversity in three of them confirmed their favourable status. Habitats with dominant deciduous trees (9020 Fennoscandian hemiboreal natural old broad-leaved deciduous forests rich in epiphytes and 9180 Tilio-Acerion forests of slopes, screes and ravines) distributed in the area Environs of Lakes Žalieji were characterised by a large number of epiphytes, among which there were also indicators of favourable habitat conservation status. In both habitats, Dicranum viride was recorded. Our research did not reveal bryophyte species indicating the favourable status of 9010 Western taiga habitats. In contrast, small areas of wetland habitats are of favourable conservation status. Three typical bryophyte species (Hamatocaulis vernicosus, Sphagnum warnstorfii and Tomentypnum nitens) were recorded in 7140 Transition mires and quaking bogs (the area Ežerėliai Complex). The results of our study confirm that some habitats of Vilnius outskirts, despite increased pressure of urbanisation, are still able to maintain favourable status.

Nanotechnology, with its research and results, has become one of the essential fields among scientific disciplines. Nanotechnology is used in many areas of science such as physics, chemistry, pharmacology, materials science, medicine and agriculture. The use of nanotechnology could provide breakthroughs that would revolutionise many scientific studies. The role of nanoparticles in plant nutrition under soil pollution represents a comprehensive overview of nanotechnology in agriculture related to the importance, recycling, and transformation of nanoparticles. Nanomaterials are used in plant protection, nutrition, and the management of agricultural practices. The new challenges nanotechnology faces today include using biological or green synthesis methods to produce nanoparticles and offset the toxicity of conventionally integrated nanoparticles. The efficiency of nanoparticle uptake and the effects of nanoparticles on growth and metabolic functions differ between plant species. The concentration of nanoparticles affects processes such as germination and plant growth and development. The agriculture sector has also profited from various nanotechnology-based products such as nanofertilisers, nanopesticides, nanogrowth promoters, and many more for sustainable agriculture and crop improvement.

Epipactis albensis Nováková & Rydlo (Orchidaceae), a species new to the flora of Lithuania, was found in the southwestern part of the country, in the Bukta Forest (the Žuvintas Biosphere Reserve, Marijampolė district) in 2020, and the nearby Dalginė Forest (the Dalginės Botanical Reserve) in 2021. The closest isolated population is located ca. 340 km southwest, and newly recorded populations form an island outside the main distribution area. Species populations occur primarily in the Tilio-Carpinetum betuli plant community showing ecological plasticity. A part of the population occurs in habitats with anthropogenic influence. Epipactis albensis is the only obligate autogamous Epipactis species known in Lithuania until now. Although its flowering season starts at the end of July or the beginning of August, solitary flowering specimens can be found in September or even later. According to the assessment applying the IUCN criteria, species should be treated as endangered (EN) [B2a,b(ii)c(iv) D] in Lithuania.
