New stage of the invasion: Sporobolus vaginiflorus (Poaceae) reached Hungary

Abstract

Sporobolus vaginifl orus, a “for a long time expected” invasive alien of North American origin has now reached Hungary. Th e fi rst stands were recorded in 2015 in SW Hungary on the
\nmotorway M70 near Letenye; its occurrence was already foreseen in view of its expansion along the roads of Croatia and Slovenia. Similarly to other aliens (e.g. Senecio inaequidens, Plantago coronopus) arriving from the Adriatic direction on the newly constructed motorways the authors reckon with its further rapid expansion in Hungary.
