Ephemerum cohaerens and E. rutheanum: persistent annual bryophytes in the Dutch Rhine floodplain

[摘要] Ephemerum cohaerens and E. rutheanum have been found in 12 localities in the Dutch Rhine floodplain between 2004 and 2011, mainly in the eastern reach (Upper-Rhine and Waal). The first species is very rare in western and central Europe, the latter is a European endemic known from six countries only. All localities represent the Natura 2000 habitat type 3270, ‘Rivers with muddy banks with Chenopodion rubri p.p. and Bidention p.p. vegetation’ comprising vegetation types with a late annual development on banks of former meanders, scour holes and sand and clay pits in forelands.
