The paper provides information about a finding of a remote population of the Pteris cretica fern which occurs mainly in subtropical regions of the World. The species was discovered in 2016 in an old well of the Letovice Castle (W Moravia, Czech Republic). Since this fern has never been recorded in the Czech Republic before, it is the first record for the national flora. Only a single specimen was discovered growing in the gap in the lining of the well, at a depth ca 3 m. The plant probably belongs to the var. albolineata which is often cultivated as a houseplant; this is a probable source of spores, and an explanation for this new occurrence. Since this taxon was recorded in similar habitats in Germany and Belgium, details related to this new occurrence can be compared. Several other fern species were observed in the well including the critically endangered Asplenium scolopendrium. [ABSTRACT FROM AUTHOR]

Although the Štramberk Karst is one of the most important botanical sites of the northeastern Moravia, the local forest vegetation has been poorly studied so far. For this reason, we conducted field sampling focusing on mesophilous forest vegetation, especially on the scree- and rock-outcrop forests. We recorded 16 phytosociological relevés and basic environmental variables of the plots. We divided our relevés into three main vegetation types using numerical analysis: beech forests, rock-outcrop forests and ravine forests. Among them, we distinguished six associations, four of them belonging to the alliance Tilio platyphylli-Acerion (1 to 4) and two of them to the alliance Fagion sylvaticae (5 and 6): (1) Aceri-Tilietum, (2) Arunco dioici-Aceretum, (3) Mercuriali perennis-Fraxinetum, (4) Seslerio albicantis-Tilietum, (5) Galio odorati-Fagetum and (6) Mercuriali perennis-Fagetum. Occurrence of the rare rock-outcrop forest association Seslerio albicantis-Tilietum is remarkable, since several endangered and relict species occur here (e.g. Laserpitium latifolium, Saxifraga paniculata, Scabiosa lucida subsp. calcicola). This is the first record of this association in the north-eastern Moravia. [ABSTRACT FROM AUTHOR]

The valley of the Třebůvka River between the municipalities Městečko Trnávka and Loštice (Central Moravia, Czech Republic) has been poorly known in a phytosociological sense. Therefore, a field survey was led and vegetation of the site Babí skála near the village Jeřmaň is described in this study. The site is a steep rocky slope above the Třebůvka River built up by acidic Paleozoic shales; it is covered mainly by well-preserved deciduous forests. Dominant forest vegetation types are acidophilous oak forests, mesophilous (association Luzulo-Quercetum), semithermophilous (Viscario-Quercetum) and thermophilous (Sorbo torminalis-Quercetum) ones. On the slope basis, scree forests dominated by noble deciduous trees (Aceri-Tilietum) are growing. Primary shrub vegetation is represented by scrubs of Cotoneaster integerrimus that can be found on the tops of some rock outcrops (Junipero-Cotoneasteretum integerrimi). Among non-forest vegetation an acidophilous rock vegetation from the alliance Asplenion septentrionalis is the most important. The most remarkable species in the flora of the locality are light-demanding (Arabidopsis arenosa, Carex rhizina and Cotoneaster integerrimus) and thermophilous (e. g. Polygonatum odoratum and Vincetoxicum hirundinaria) ones. [ABSTRACT FROM AUTHOR]
