Abstract
Chromosome numbers for four Spiraea species were determined ( S. betulifolia Pall., S. ussuriensis Pojark., S. media Schmidt, S. fl exuosa Fisch. ex Cambess.), two of them for the first time ( S. betulifolia , S. ussuriensis ). Th e number of nucleoli in interphase nuclei of these species was counted.
