Yeremenko N. (2019): Ruderal vegetation of the class Polygono- -Poetea annuae in Kryvyi Rih (Ukraine) – Thaiszia – J. Bot. 29 (1): 001-021. – ISSN 1210-0420.
Abstract: The present paper studies the ruderal vegetation of the class Polygono-Poetea annuae in Kryvyi Rih. We present the ruderal plant communities of short annual species on the open, moist to dry ecotopes. Urban landscapes remain unstudied phytosociologically despite the highly diverse habitat niches. We have carried out the comparisons of communities from other regions of Ukraine and adjacent territories. In total, two associations and two variants, belonging to alliance were identified and categorized as follows Polygono-Coronopodion (the communities with the dominance of Polygonum aviculare). The ordination analysis indicates ecological differentiation of syntaxa investigated in Kryvyi Rih. The most important of them are soil water regime (Hd), variability of damping (fH) and soil aeration (Ae).
Keywords: syntaxonomy, classification, trampled vegetation, ecological differentiation.

Kučera P. (2019): Two new wet woodlands with Norway spruce from the Western Carpatians. – Thaiszia – J. Bot. 29 (1): 023-049. – ISSN 1210-0420.
Abstract: Two new associations of wet woodlands with Picea abies from the Western Carpathians are described. Stands of the first unit, Leucobryo glauci-Piceetum abietis, are located on dryer margins of mires, on plains where water from snow melting and rains remains considerable long above the soil surface. The most characteristic sign of the species-poor flora of this forest plant community is the dominance of moss Leucobryum glaucum accompanied by constant presence of Sphagnum spp. Two subassociations are distinguished in respect of the ecological differences. The second described plant community, association Stellario nemorum-Abietetum albae, occupies quite different habitat of spring areas and other more wet localities. Abies alba plays an important role in the canopy, field layer is characterised by constant presence of Stellaria nemorum, Equisetum sylvaticum, Oxalis acetosella, Senecio ovatus, Chaerophyllum hirsutum, Lysimachia nemorum and other species. Three subassociations and five variants are distinguished.
Keywords: Abies alba, ground-water, mire, Picea abies, phytocoenology, spring areas, syntaxonomy, Western Carpathians.

Abstract: New distribution data of Taraxacum cristatum (T. scanicum group), described in the year 2005, in Slovakia were recorded. During the intensive study of Slovak dandelions in herbarium collections and field course, additional 22 localities were found. The species has been recorded in 17 phytogeographical districts up to now, with the highest frequency in the western and the southern part of the country, preferring dry and xerothermic steppe grasslands, pastures and dry meadows from the class Festuco-Brometea. The altitudinal maximum in Slovakia, in 668 m a. s. l. was recorded in the Strážovské vrchy Mts. on the top of Mt. Baba. The updated distribution map is attached.
Keywords: dandelion, Central Europe, xerothermic habitats, Taraxacum scanicum group.

Kučera P. (2019): Quercus banatus grows in Slovenia. – Thaiszia – J. Bot. 29 (1): 061-069. – ISSN 1210-0420.
Abstract: Occurrence of Quercus banatus P. Kučera (= Q. aurea Wierzb., nom illeg.; Q. dalechampii auct. medioeur. non Ten.) was confirmed in Slovenia during a brief trip to Škocjan Caves in the Škocjan Caves Regional Park (southwestern Slovenia). The species is not recognized in the national Slovenian flora – Mala flora Slovenije, although it was recorded in the Atlas Florae Europaeae (under the name “Q. dalechampii”). Q. banatus individuals were recently found on two sites: on the slope of a natural bridge between collapse dolines Velika dolina and Mala dolina and on parking lot next to the Park’s Information Centre.
Keywords: distribution, Quercus, Quercus petraea group, Škocjanske jame.

Abstract: Chinese silver grass Miscanthus sinensis Andersson is native in southeastern Asia. It has been recorded as new to the vascular flora of Bosnia and Herzegovina, at two localities near the town of Zavidovići. The paper presents a short morphological description, photographs of the new alien species for Bosnia and Herzegovina, as well as the distribution of the taxon.
Keywords: alien plants, Bosnia and Herzegovina, distribution, Miscanthus, morphology.

Abstract: First two records of Eleusine indica in Slovakia are presented. This exotic grass species originating from the tropical Old World was found in the Podunajská nížina Lowland (Eupannonicum): in 2017 in Štúrovo and the next year in Bratislava, municipal part Karlova Ves. Both populations counted only three individuals grown in the pavement cracks. The habitat conditions of each locality in detail are characterized. Whereas Slovakia is among the last countries where E. indica was just discovered within Europe, we discuss the environmental conditions and the origin of the species in the backlight of earlier studies related to its occurrence in the surrounding countries.

Abstract: Little attention is being paid to Amaranthus caudatus in the Eastern Cape Province and other parts of South Africa as a vegetable that has huge potentials in bridging nutritional gap between the rich and the poor. This work investigated germination response of the plant to environmental conditions and variation in its germination characteristics at various depths in different soil types with the intent of complementing limited data available on the general agronomy of the species. At the end of the study, the highest germination was recorded at 25 °C and under continuous dark conditions, although the seeds germinated well under a wide range of temperatures and other photoperiods. The species germinated under all seeding depths considered, though late emergence was observed at depths below 2 cm. In addition, a significant (P < 0.05) interaction in pattern of germination was observed in three out of the five soil types tested, whereas the control (unfractionated) soil showed a highly significant (P < 0.01) interaction with the silt clay loam and loam soil. This overlapping interaction further confirmed that the plant has wide surviving capabilities in various soils and environmental conditions, hence, for optimum seedling emergence, it is recommended that A. caudatus be planted in a loamy soil maintained at 25 °C in a continuous dark environment.
Keywords: Alternating temperatures, Amaranthus caudatus, germination characteristics, photoperiods, sowing depth

Abstract: The third part of the series includes 28 new chorological records of vascular plants from Austria, Czechia, Slovakia, Transcarpathian Ukraine and Romania. From Austria, new record of Hyoscyamus niger was reported. In Czechia in the Bílé Karpaty Mts., new sites of Corydalis lutea, Ranunculus arvensis and Thlaspi perfoliatum were recorded. In eastern Slovakia, two neophyte species Robinia viscosa and Pyrethrum parthenium were found and the new altitudinal maximum for halophyte species Taraxacum bessarabicum in 418 m above sea level was recorded. In the Ukrainian Carpathians, new sites of Lycopodium alpinum and Phyteuma vagneri in the massif of the Polonina Krasna were found as well as new records of Aronia melanocarpa and Inula helenium in the valley of the Latorica river. From the Romanian Carpathians, Festuca stricta subsp. saxatilis, Pulmonaria filarszkyana, Saxifraga luteoviridis and Silene zawadzkii in the Maramureş Mts. were recorded as well as rare orchid Ophrys insectifera from Retezat Mts.
