Abstract: This paper reports on the new occurrences of two alien species, Eleusine indica and Phytolacca
esculenta in Eastern Hungary (in microregions of Great Hungarian Plain and North Hungarian
Range units). Previously very scattered observations were documented from this part of
the country. This correspondence describes the newly discovered localities of these species and
presents the actualised CEU-based grid distribution map. I observed Eleusine indica in 5 new grids
in 2018, which might refer to the present expansion of the species on trampled synanthropic habitats
(mostly along roads). In the case of Phytolacca esculenta new occurrences increased signifi -
cantly our knowledge concerning its distribution. Based on recent floristical investigations carried
out between 2008 and 2019, it is registered from 10 microregions covering 37 new CEU grids (representing
a 29.6% increase in data compared to previous data). Th e occurrence at Bükkszentkereszt
(Bükk Mts) represents the population with the highest altitude record (607 m a.s.l.) so far known in
Hungary. The species can colonise with ‘soft invasion’ variable synanthropic habitats, mostly in urban
environs, thus some locations outside from the villages were also detected. The importance of
the green (garden) waste deposition heaps is also considerable, which can serve as ‘stepping stones’
in the naturalisation process of the species.Keywords: distribution, urban flora, flora mapping, green waste, invasive alien species, range expansion
