Rubus flora of old cemeteries, not used for burial in the Wielkopolska region

Floristic surveys of bramble flora were conducted in 2005–2020 in more than 2150 old cemeteries (no longer used for burial) in the Wielkopolska region or Greater Poland. Forty Rubus species were found, in 972 cemeteries. Two taxa were new to the Polish flora: R. armeniacus and R. nemoralis f. laciniatus. Species new to this region were R. acanthodes, R. crispomarginatus, and R. praecox
