A Sisyrinchium bermudiana agg. újabb előfordulásai Magyarországon
Riezing Norbert – Óvári Miklós
The Blue-eyed grass (Sisyrinchium bermudiana agg.) can be found in two places in Hungary: in Vértesalja and in the middle part of Egerszeg-Letenye-hills, in both cases on secondarily developed grasses. In the Vértes habitat, which is a mine-recultivation area, the soil changes from semi-dry to wet (it prefers the wet areas), its chemical reaction is slightly limy, its nutrient-suppy is changeable, mainly submesotrophe. In Zala county it is settled on xerotherm areas, on basical, shallow soil, that was formed on loess.
The taxonomical classing of the european plants is debated, but this question is not yet solved in its original country, North-America either. Based on the different bibliographies, for the time being the authors suggest using the name Sisyrinchium bermudiana agg.
At the moment the plant is a rare adventive species, its appearance in large numbers is not likely, nevertheless we must pay attention to it, as many suitable habitats can be found in the country. In the neighbouring countries it is more and more frequent, moreover recently it was taken (again) into gardening culture. It may happen (based on foreign data), that it will disappear for some decades, then it will appear again. After blooming it is characterless which makes it difficult to find, and is not easy to recognise because of its grass-likely appearance.
