CHROMOSOME NUMBERS OF SOME VASCULAR PLANT SPECIES FROM THE AMUR RIVER BASIN AND PRIMORYE (THE RUSSIAN FAR EAST)
The chromosome numbers (2n) in 44 vascular plant species from the Amur River basin and from Primorye (south of the Russian Far East) are presented. For the first time they are revealed in Elsholtzia serotina Kom. (2n =16) and Heteropappus probatovae Tzvel. (2n = 18). Also the new chromosome data are obtained for Calamagrostis macrolepis Litv., Eragrostis multicaulis Steud., Potamogeton na-tans L., and Quercus mongolica Fisch. ex Ledeb. Some species have been studied for the first time in Russia or in the Russian Far East.
