Abstract: Rubus guttiferus, known mainly from the Czech Republic, has been found on 25 localities in Lower Silesia (SW Poland). It is as yet a rare bramble there, on the northern border of its range, forming usually very small local populations, and as such should be regarded provisionally as an endangered species in Poland.
