Cahyanto T., Efendi M., Nisa N. K., Nurhalim H., Rahman W. & Fadillah A. (2022): A survey of the genus Lasianthus in Mount Burangrang, West Java. – Thaiszia – J. Bot. 33 (1): 001-028. –

Abstract: A survey of the genus Lasianthus and its morphological study based on living specimens was conducted at the Mt. Burangrang, West Java, in order to update the existing Lasianthus data. Sampling was carried out in three regencies around the Mt. Burangrang: West Bandung, Subang and Purwakarta. A total of 19 species were recorded from Mt. Burangrang. Those species covered three sections: sect. Nudiflorae (nine species), sect. Lasianthus (nine species) and sect. Stipulares (one species). Based on the collected specimens, the delimitation of the Asian Lasianthus as having 3-9 pyrenes is no longer applicable. The specimens of L. capitatus from the Mt. Burangrang contained 9-12 pyrenes. The existence of L. rufus (Korth.) Miq. is also discussed. The details of morphological description of the Mt. Burangrang Lasianthus are provided.
Keywords: diversity, Lasianthus capitatus, morphology, Rubiaceae.

Ražná K., Ďurišová Ľ., Kučka M., Harenčár Ľ., Ivanišová E., Habán M. & Hrubík P. (2022): A rare cultivar of horse chestnut (Aesculus hippocastanum L. ˈBaumaniiˈ) in Slovakia: morphological, molecular and antioxidant analysis. – Thaiszia – J. Bot. 33 (1): 029-044. –

Abstract: Aesculus hippocastanum L. ˈBaumaniiˈ (syn.: A. hippocastanum L. ˈFlore Plenoˈ; A. hippocastanum ˈPlenaˈ) is a rarely cultivated cultivar characterized by fully white and sterile flowers, and as a result it does not produce fruit. For identification and characterization of the morphological, molecular, and biochemical parameters of this cultivar, we performed the pollen viability test, morphological analysis of flowers, assay of miRNA-based markers and biochemical analyses. The results show that the germination of pollen grains in artificial media reached 0 % and the pistil in flowers was undeveloped. The antioxidant activity, total polyphenol and flavonoid content exhibited the highest values of all three tested parameters (1.5540 mg TEAC/g FM; 3.7278 mg GAE/g FM and 1.328 mg CAE/g FM) in the extracts from A. hippocastanum ˈBaumaniiˈ. The applied miRNA-based markers showed a sample-specific and tissue-specific genomic polymorphism. Various DNA fingerprinting profiles between the flowers and leaf samples of fruiting and barren trees were noted.
Keywords: horse chestnut, inflorescences, pollen, miRNA-based markers, antioxidant activity.

Kricsfalusy V. V. (2023): The non-native flora of Redberry Lake Biosphere Reserve, Canada. – Thaiszia – J. Bot. 33 (1): 045-061. –

Abstract: A checklist of alien plants of Redberry Lake Biosphere Reserve in the province of Saskatchewan, Canada is presented for the first time. By way of field surveys and herbarium research, 121 alien taxa (22.1% of the regional flora) were recorded. The most species rich families are Poaceae (24 taxa, 19.8%) and Asteraceae (22, 18.2%). Species richness is about evenly distributed across genera with Rumex, Artemisia and Poa (each contains 3 taxa or 2.5%) making up those with the greatest number of species. Concerning plant growth habits, the two dominant groups are forbs (94 taxa, 77.7%) and graminoids (23 taxa, 19%). Regarding habitat preferences, most alien plants occur in natural and seminatural habitats (48 taxa, 39.7%), ruderal places (43 taxa, 35.5%) and agricultural lands (30 taxa, 24.8%). In relation to the state of spread, invasive (63 taxa, 52%) and naturalised (48 taxa, 39.7%) species prevail. In terms of geographical origin, most alien plants are native to Eurasia–Africa (49 taxa, 40.5%) and Eurasia (34 taxa, 28.1%). The biosphere reserve is increasingly being invaded by alien plants whose introduction and distributions can be explained by intense agricultural pressure which resulted in extensive habitat alteration and proliferation of invasive species.
Keywords: alien plants, biodiversity, flora, invasiveness, invasion management, protected areas, Saskatchewan.

Iliev M. & Bozhanska T. (2023): Effect of a compost fertilizer on the productivity and botanical composition of a natural grass stand under mountain conditions. – Thaiszia – J. Bot. 33 (1): 075-085. –

Abstract: The aim of the study was to determine the impact of compost of bracken (Pteridium aquilinum L.) and fresh cattle manure on the yield and the change in the botanical composition of a natural grass stand under mountain conditions. The annual application of compost in a natural meadow of a transitional type with Chrysopogon gryllusAgrostis capillaris, increased significantly (P <0.001) the amount of dry matter in the treated variants from 57.77% (at a fertilizer rate of 3000 kg/dka) to 73.79% (at a fertilizer rate of 2000 kg/dka) compared to the untreated control. Grass stands fertilizerd at a rate of 2000 kg/dka increased to the highest degree the presence of legume components (from 44.7% to 71.2%) in the biomass, which is a prerequisite for the production of fodder with a high crude protein content. The compost application had a positive impact on the grass mass composition and contributed to positive changes in the group of desirable legume and grass meadow species. An increased share of useful legume (Trifolium pratense, T. hybridium, T. agrarium and Lotus corniculatus) and grass meadow species (Agrostis capillaris, Festuca rubra, Cynosurus cristatus and Poa pratensis) and stimulation of their productive potential was found. In the fertilized variants, the percentage share of weeds participate followed a downward trend compared to the control. Fertilizing with compost of bracken and manure is a highly effective measure and can be recommended to increase hay yields in natural grass stand (а transitional type with Chrysopogon gryllus-Agrostis capillaris) in the conditions of the Central Balkan Mountain.
Keywords: fertilizing, Pteridium aquilinum, manure, yield, floristic composition.

Riezing N. (2023): Polygonum graminifolium Wierzb. in Slovakia and along the Hungarian-Slovak border on the Danube. – Thaiszia – J. Bot. 33 (1): 087-092. –

Abstract: Polygonum graminifolium Wierzb. is a poorly known plant that has been overlooked by botanists for more than half a century and until recently had no current records in Hungary and Slovakia. The study examines the occurrence of the species along the Hungarian-Slovak border on the Danube. In addition to old literature and herbarium data, it presents the currently known occurrences. Some of these, including the Slovakian one, are new localities. It is a rare plant on the open gravel (or stony) surfaces of the riverbed, which have been dry for a long time. Other species are often absent in these habitats. Other species (in low numbers) are found mainly where some silt or sand has been deposited between the gravels or stones. Polygonum graminifolium may occur elsewhere along the Danube, but it is often difficult to find.
Keywords: floodplain, gravelly soil, pioneer vegetation, rare species.

Turis P., Turisová I., Felbaba-Klushyna L. & Voloshchuk M. M. (2023): Notes on the occurrence of selected sozologically and phytogeographically important plants in high-mountain area of the Svydovets and Chornogora (Ukrainian Carpathians). – Thaiszia – J. Bot. 33 (2): 105-116. –

Abstract: Findings of threatened, rare, endemic, relict and phytogeographically important species of high-mountain plants, obtained during a research of the surroundings of glacial lakes Velykyy Apshynets, Brespo and Brebeneskul in the Ukrainian Carpathians in 2021, are presented. The species occurrence data contribute to the knowledge of the precise geographical distribution or chronological representation of sozologically important species Allium schoenoprasum, Carex capillaris, C. limosa, C. pauciflora, Heracleum carpaticum, Juncus castaneus, J. triglumis, Salix phylicifolia, Scheuchzeria palustris and Swertia punctata in Svydovets and Chornogora Mts. The importance of collecting new chorological data but also updating the previous ones is emphasized by a need to create the plant Red List for the Ukrainian Carpathians based on the newest IUCN criteria that were not yet taken into account.

Keywords: high-mountain flora, threatened species, endemics, relicts, glacial lakes.

Deka N., Patgiri S. R. & Sharma B. (2023): Distribution of endophytic fungi in the leaf and stem of Cissus quadrangularis Linn. – A comparative study. – Thaiszia – J. Bot. 33 (2): 117-124. –

Abstract: The present study focused on the diversity and distribution of endophytic fungal species in different plant parts (stems and leaves) of the plant Cissus quadrangularis Linn. collected from different locations of Assam, India. Plant samples were collected from three districts, Kamrup, Barpeta and Biswanath of Assam for endophytic fungal isolation. Variation was found in the distribution of fungal endophytes in stems and leaves of the plant collected from different locations under study. The percentage isolation of the endophytic fungal isolates was more from the stems collected from Kamrup (M) whereas the percentage isolation of endophytic fungal isolates was more from the leaves collected from Biswanath Chariali and Barpeta. Shannon-diversity and Simpson diversity indices of fungal endophytes varied in stems and leaves of the plant under study. This variation can be attributed to the soil conditions of the sampling site as well as the seasonal variation during sampling periods. Cladosporium sp. and Fusarium sp., are the most dominant and frequently occurring endophytic fungal species in C. quadrangularis of Kamrup (M) and Barpeta districts. Colletotrichum sp. and Rhizopus sp. were the dominant endophytic fungal species in Biswanath district. Since C. quadrangularis is used traditionally in the treatments of bone fracture, the study of endophytes associated to this plant could be of paramount significance with a scope of identifying the potent endophytes that are capable of producing bioactive compounds necessary in bone-healing.
Keywords: Cissus quadrangularis, fungal endophytes, medicinal plant, percentage isolation, Shannon diversity index, Simpson’s diversity index.

Sadygov R. & Felbaba-Klushyna L. (2023): The bryoflora of the Zacharovana Dolyna Reserve (the Ukrainian Carpathians): species diversity and taxonomic structure. – Thaiszia – J. Bot. 32 (2): 125-138. –

Abstract: Zacharovana Dolyna is a Ukrainian national geological reserve that was established in 1978. In 2009, it formed the basis for establishing the National Nature Park Zacharovany Krai, and now it is the most interesting part of the park regarding its environmental diversity. Investigations of the biodiversity of this park remain at the initial stage, and data on bryophytes are not available so far. We identified 114 bryophyte species, including 45 species that were proven new to the Volcanic Carpathians. We performed a taxonomic analysis of the bryoflora and clarified that Mniaceae (10 species), Polytrichaceae (8 species), and Brachytheciaceae (8 species) were the species richest families; the last one mentioned belongs to the three species richest families of the Ukrainian Carpathians. Most species of the families Mniaceae, Polytrichaceae and Brachyteciaceae prefer overmoistened ecotopes prevailing in the studied area, including wet rocks and stones along streams. A special feature of the Reserve is that a significant percentage of the species were found on stony substrates. The bryophyte flora documented here also includes the species of conservation concern. Pseudohygrohypnum fertile is considered vulnerable, endangered, or rare in many European countries, while Dicranum viride is the Bern Convention species. Neckera pennata is especially rare for Zakarpattia and is a vulnerable species listed in the Ukrainian Red List of Bryophytes. We registered a high species diversity of bryophytes in a relatively small area of the Zacharovana Dolyna Reserve due to the high diversity of potential bryophyte substrates and microhabitats.
Keywords: Volcanic Carpathians, National Nature Park Zacharovany Krai, mosses, liverworts, substrates, Pseudohygrohypnum fertile, Dicranum viride, Neckera pennata.
