| Description | Urtica kioviensis was for the first time found in the Czech Republic in 1947 near the town of Moravský Písek in southeastern Moravia. It has been the only find ever until recently, and the species has been considered extinct since the early 1990s. In June 2001, another population of U. kioviensis was discovered in a temporary pool, surrounded by a hardwood floodplain forests, in the National Nature Reserve Ranšpurk south of the town of Lanžhot (South Moravia, distr. Břeclav). The site is situated in the floodplain of the Dyje River about 10 km of the northernmost localities of the species near the village of Hohenau along the March/Morava River in Lower Austria. Urtica kioviensis can be distinguished from U. dioca by its bright green colour, shiny leaves, glabrescence (only stinging hairs present), long creeping stem, usually rooting at lower nodes, and triangular, above sometimes connate stipules, as well as by its monoecism. It is a continental plant of river corridors occurring from southern Russia in the east to Hungary in the west, with some isolated localities in Slovakia, eastern Austria, eastern Czechia, central Germany, and Denmark. In Central Europe, it is confined mainly to alder and willow carrs, exposed bottoms and banks of temporary pools and river oxbows, and different types of reed beds, all being permanently wet or temporarily flooded habitats. Urtica kioviensis forms creeping, densely leafy stems in autumn, which remain green till early spring. |
