Eleusine indica (L.) Gaertn., new species of the adventive flora of Slovakia

First two records of Eleusine indica in Slovakia are presented. This exotic grass species originating from the tropical Old World was found in the Podunajská nížina Lowland (Eupannonicum): in 2017 in Štúrovo and the next year in Bratislava, municipal part Karlova Ves. Both populations counted only three individuals grown in the pavement cracks. The habitat conditions of each locality in detail are characterized. Whereas Slovakia is among the last countries where E. indica was just discovered within Europe, we discuss the environmental conditions and the origin of the species in the backlight of earlier studies related to its occurrence in the surrounding countries.
