Sabaghnia N., Moayed F. N. & Janmohammadi M. (2024): Genetic variation and interrelationships of sainfoin genotypes as revealed by morphologic and agronomic markers. – Thaiszia – J. Bot. 35: 001–014. – https://doi.org/10.33542/TJB2025-1-01
Abstract: Sainfoin (Onobrychis viciifolia Scop.) as an ancient forage crop has garnered interest due to its desirable characteristics and adaptability. This investigation was designed to study genetic variation and interrelationships of sainfoin via factor analysis and clustering methods. Thirty-two local native genotypes were collected from various geographical regions and assessed based on a randomized block scheme with four replicates. The first five factors explained 85% of the variance and were named yield performance, plant morphology, powdery mildew, forage quality and forage palatability. The first factor described 58% of the variability, encompassed forage yield and its related characteristics like stem number per plant, main stem’s nodes, length of the longest stem, main stem’s internodes, stem’s leaves, stem fresh weight, leaf fresh weight, inflorescence fresh weight, stem dry weight, leaf dry weight, fresh weight and dry weight per unit area. The dendrogram of sainfoin genotypes is categorized genotypes into three groups, which is confirmed via the Wilks’ lambda of multivariate analysis of variance. Group-1 contains 10 genotypes with the highest forage yield performance, and high amounts for most of the other remained traits. Group-2 contains 9 genotypes with the lowest performance for most traits of powdery mildew, suggesting their good potential for powdery mildew tolerance, while Group-3 contains 13 genotypes and indicated moderate performance for measured traits of sainfoin. The ten desirable genotypes of Group-1 mostly from northwest Iran, were good candidates for commercial release in Iran because they performed well and had high values of most traits, so they can be advised for cultivation in cool upland rainfed conditions of semi-arid regions.
Keywords: Onobrychis viciifolia Scop., genetic diversity, cluster analysis, factor analysis.

Abstract: Three plant communities of Glycerio-Sparganion alliance were studied in recent years in Slovakia. Rorippo ancipitis-Catabrosetum aquaticae was previously mentioned only from the Drienčanský kras Mts, while the occurrence of the other two associations, Glycerio notatae-Veronicetum beccabungae and Polygono hydropiperis-Veronicetum anagallidis-aquaticae, was only generally mentioned from Slovakia. Based on a field study and published sources, all three associations were documented by 12 phytosociological relevés. Comparison of Rorippo ancipitis-Catabrosetum aquaticae with Catabroso-Polygonetum hydropiperis (Bidentetea class) was discussed. List of communities of the Glycerio-Sparganion alliance was added; altogether 8 associations are recently mentioned from Slovakia.
Keywords: Glycerio notatae-Veronicetum beccabungae, marsh vegetation, Polygono hydropiperis-Veronicetum anagallidis-aquaticae, Rorippo ancipitis-Catabrosetum aquaticae.

In Slovakia Bromus secalinus, Elatine hungarica, Elymus elongatus, Ranunculus polyphyllus and Vaccaria hispanica were reported. Alien Cymbalaria pallida has been recorded for the first time in the flora of Slovakia.

Studnička M. (2025): Unexpected species of Anthurium at the Seibal archaeological site (Guatemala) as a possible trace of Maya long-distance trade. – Thaiszia – J. Bot. 35: 042–047. – https://doi.org/10.33542/TJB2025-2-01
Abstract: Three archaeological sites of Maya structures close to one another, namely Cahal Pech (Belize), Seibal and Tikal (both Guatemala), have been examined as habitats of epiphytic or petrophytic species of the genus Anthurium (Araceae). A. schlechtendalii Kunth is found in the area and is a species common in Maya ethnobotany. Nevertheless, a large naturalised population of the very similar but larger species A. salvinii Hemsley has been detected in Seibal. This site is separate and geographically isolated from the natural habitats of A. salvinii in Guatemala. This phenomenon elucidates a possible ethnobotanical trace of Maya long-distance trade in pre-Columbian history.
Keywords: archaeological site, Guatemala, Maya, ethnobotany, pre-Columbian, Anthurium.

Abstract: This article presents the hitherto known records of Ornithopus perpusillus in Hungary. The species was first found in central Hungary as early as 1952, but was identified as O. sativus. It was (re-)discovered in southwestern Hungary in 2010 at several localities, in disturbed, open sandy grasslands, with co-occurrence of other Atlantic-Mediterranean species. O. perpusillus was likely introduced in Hungary at the beginning of 2000s, and now it is considered to be naturalized here.
Keywords: Central-Europe, sandy vegetation, Leguminosae, introduced species.

Abstract: The Biloozerskyi National Nature Park is a significant protected area in the Left-Bank Forest-Steppe of Ukraine and includes forest, wetland, and aquatic ecosystems. The flora of this park was shaped by the combined influence of natural components of the northern mixed (oak-pine) forest and forest-steppe zones, which makes it unique compared to other nature protected areas in the region. The study revealed the presence of 851 species and subspecies of vascular plants on this territory, of which 684 are native and 167 are alien. For the first time, alien plant species Rubus balticus has been included in the list of the flora of Ukraine. The most representative families are Asteraceae, Poaceae, Cyperaceae, Rosaceae, Caryophyllaceae and Lamiaceae. The most species-rich genera are Carex, Veronica, Trifolium and Pilosella. Geographic analysis of the flora indicates the dominance of widespread species (48.6 %) among native plants, as well as European (17.8 %) and Euro-Mediterranean (13.4 %) zonal elements. In contrast, the alien fraction is mainly represented by species of Mediterranean (46.7 %) and American (23.4 %) origin. The biomorphological structure of the native flora is characterized by a predominance of perennials (65.2 %), whereas the alien fraction includes a larger proportion of annuals, biennials and short-lived (60.5 %). Meadow-steppe, forest, and wetland plant communities play a crucial role in shaping the floristic composition of the park. The highest species richness is observed in pine forests, meadow steppes, and in riparian ecosystems. The flora of the park has significant conservation value, as 107 rare and endangered species have been identified, 25 of which are listed in the Red Data Book of Ukraine. At the same time, 35 invasive species have been recorded, such as Acer negundo, Asclepias syriaca, Solidago canadensis and Robinia pseudoacacia, which pose a threat to natural plant communities.
Keywords: biodiversity, protected area, native plants, rare species, alien species, conservation.

Abstract: Two aquatic bryophytes of Northern character, Fissidens fontanus and Leptodictyum riparium, are reported for the first time from the Arabian Peninsula. A synthesis based on new field observations and a review of the literature provides an overview of the aquatic bryoflora of the Peninsula. The five species forming this exceptional assemblage in Arabia are mapped. They are restricted to wadis (dry riverbed that flows only after rain) carved into granite bedrock that efficiently channel and concentrate rainfall runoff – particularly under the influence of the monsoon – into localized zones of persistent moisture. The conservation status of these species is briefly discussed.
Keywords: aquatic bryophytes; impluvium; Asir mountains; Fontinalis hypnoides; Leptodictyum riparium; Rhynchostegium riparioides.
