A Ferula sadleriana Ledeb. "újabb" hazai lelőhelye
During a field trip near Csobánka village (6 km NW of Budapest in Pilis Mts) a new locality of Ferula sadleriana was discovered in 2006. The population is living in a mosaic of rocky grassland and shrubland on the cliffs of Mt Kis-Kevély. Though this locality has been unknown to the authorities and botanists so far, it is more than probable that the population is not aboriginal and was planted about 20–25 years ago.
