  Two alien species from the Rubiaceae family were recorded as new for Hungary in 2016. Phuopsis stylosa is a rarely used garden plant in Europe, originally occurs in south-west Asia. A small escaped and established stand was found in Csákánydoroszló village in Vas County (West Hungary). Also a small group of Galium murale was discovered in Budapest-Keleti Railway Station (Central Hungary). This species is originated from the Mediterranean and probably spreads by rail transport. Both species are represented in their habitats by small populations therefore their invasiveness can only be evaluated after several years' monitoring.

  In the second part of our series providing data on alien plant species in Hungary, we add­ress taxa belonging to the families Cabombaceae, Brassicaceae, Rubiaceae, Buxaceae, Violaceae and Compositae. We present new records of the distribution of Cabomba caroliniana on the Körös Plain: along the Élővíz Canal between the towns of Békés and Békéscsaba the species was found at 17 sites, covering a total area of more than 630 m² in slightly alkaline, low-conductivity water that remains unfrozen in winter. In Szentendre, we document a transient escape of Isatis tinctoria and several popu­lations of Rubia tinctorum, some of which can be traced back to former cultivation. We report the first extra-garden, woodland occurrence of Pachysandra terminalis in Hungary and relate it to the dumping of green waste. We clarify the status of Viola prionantha in the Hungarian flora and list numerous oc­currences mainly associated with urban pavements, parks and cemeteries. We detected a new occurrence of the Atlantic halophyte Cochlearia danica on the Great Hungarian Plain, near Karcag, along the Main Road 4. Finally, we describe the first Hungarian record of Symphyotrichum squamatum from pioneer silt surfaces along a canal near Szeged, highlighting its potential invasive role.
