Cahyanto T., Efendi M., Nisa N. K., Nurhalim H., Rahman W. & Fadillah A. (2022):<\/strong> A survey of the genus Lasianthus <\/em>in Mount Burangrang, West Java. \u2013 Thaiszia \u2013 J. Bot. 33 (1): 001-028. \u2013 https:\/\/doi.org\/10.33542\/TJB2023-1-01<\/a><\/p>\n\n\n\n

Abstract<\/em>: A survey of the genus Lasianthus <\/em>and its morphological study based on living specimens was conducted at the Mt. Burangrang, West Java, in order to update the existing Lasianthus <\/em>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 <\/em>(nine species), sect. Lasianthus <\/em>(nine species) and sect. Stipulares <\/em>(one species). Based on the collected specimens, the delimitation of the Asian Lasianthus <\/em>as having 3-9 pyrenes is no longer applicable. The specimens of L. capitatus <\/em>from the Mt. Burangrang contained 9-12 pyrenes. The existence of L. rufus <\/em>(Korth.) Miq. is also discussed. The details of morphological description of the Mt. Burangrang Lasianthus <\/em>are provided.
Keywords<\/em>: diversity, Lasianthus capitatus<\/em>, morphology, Rubiaceae.

Abstract<\/em>: Aesculus hippocastanum <\/em>L. \u02c8Baumanii\u02c8 (syn.: A. hippocastanum <\/em>L. \u02c8Flore Pleno\u02c8; A. hippocastanum <\/em>\u02c8Plena\u02c8) 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 <\/em>\u02c8Baumanii\u02c8. 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<\/em>: horse chestnut, inflorescences, pollen, miRNA-based markers, antioxidant activity.

Kricsfalusy V. V. (2023):<\/strong> The non-native flora of Redberry Lake Biosphere Reserve, Canada. \u2013 Thaiszia \u2013 J. Bot. 33 (1): 045-061. \u2013 https:\/\/doi.org\/10.33542\/TJB2023-1-03<\/a><\/p>\n\n\n\n

Abstract<\/em>: 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 <\/em>(24 taxa, 19.8%) and Asteraceae <\/em>(22, 18.2%). Species richness is about evenly distributed across genera with Rumex<\/em>, Artemisia <\/em>and Poa <\/em>(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\u2013Africa (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<\/em>: alien plants, biodiversity, flora, invasiveness, invasion management, protected areas, Saskatchewan.

Teofilovski A. (2023):<\/strong> Verbascum matevskii <\/em>(Scrophulariaceae), a new species from North Macedonia. \u2013 Thaiszia \u2013 J. Bot. 33 (1): 063-073. \u2013 https:\/\/doi.org\/10.33542\/TJB2023-1-04<\/a><\/p>\n\n\n\n

Abstract<\/em>: Verbascum matevskii <\/em>is described, and illustrated as species new to science from the northwestern part of Nort Macedonia. It is a distinct species, to some extent similar to the Balkan endemics V<\/em>. davidoffii<\/em>, V. durmitoreum <\/em>and V. epixanthinum <\/em>var. pindicolum<\/em>, differing from each of them in several morphologic characteristics. The new species is endemic to the area south of Gostivar, where it occurs very scattered in various mesic habitats in the zone of beech forests.
Keywords<\/em>: beech forests, holotype, morphological description, new species, Verbascum matevskii<\/em>, North Macedonia.

Iliev M. & Bozhanska T. (2023):<\/strong> Effect of a compost fertilizer on the productivity and botanical composition of a natural grass stand under mountain conditions. \u2013 Thaiszia \u2013 J. Bot. 33 (1): 075-085. \u2013 https:\/\/doi.org\/10.33542\/TJB2023-1-05<\/a><\/p>\n\n\n\n

Abstract<\/em>: The aim of the study was to determine the impact of compost of bracken (Pteridium aquilinum <\/em>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 gryllus<\/em>–Agrostis capillaris<\/em>, 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<\/em>, T. hybridium<\/em>, T. agrarium <\/em>and Lotus corniculatus<\/em>) and grass meadow species (Agrostis capillaris<\/em>, Festuca rubra<\/em>, Cynosurus cristatus <\/em>and Poa pratensis<\/em>) 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 (\u0430 transitional type with Chrysopogon gryllus-Agrostis capillaris<\/em>) in the conditions of the Central Balkan Mountain.
Keywords<\/em>: fertilizing, Pteridium aquilinum<\/em>, manure, yield, floristic composition.

Riezing N. (2023):<\/strong> Polygonum graminifolium <\/em>Wierzb. in Slovakia and along the Hungarian-Slovak border on the Danube. \u2013 Thaiszia \u2013 J. Bot. 33 (1): 087-092. \u2013 https:\/\/doi.org\/10.33542\/TJB2023-1-06<\/a><\/p>\n\n\n\n

Abstract<\/em>: Polygonum graminifolium <\/em>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 <\/em>may occur elsewhere along the Danube, but it is often difficult to find.
Keywords<\/em>: floodplain, gravelly soil, pioneer vegetation, rare species.
