Current distribution of the recently described bramble species, Rubus guttiferus (Rosaceae), in Poland
Dendrobiology 2006, vol. 56: 45-49
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.
Additional key words: woody flora, new species, Sudety.
