Blechnum spicant (Blechnaceae) in the Ukrainian flora

The article contains data about the historical and current distribution patterns of Blechnum spicant (Blechnaceae) in Ukraine. This species is quite common in the Carpathian Mountains but is very rare in other regions of Ukraine. Until recently, there were only two known localities of B. spicant in the Western Forest-Steppe (within the Podolian Upland) and only one in Crimea. We discovered one new locality of B. spicant in the Polissian (Polesian) Lowland, in Volyn Region. The article provides phytosociological and topographic data on the Polissian population. This population consists of two sub-populations, which are located not far from each other. Both of them were found in an immature birch-pine forest aged approximately 20 years, in an area of former agricultural lands. We summarise the data on the general distribution of B. spicant in Ukraine. The article also provides phytosociological, biotopic and populational information on localities of B. spicant.
