Abstract
Chromosome numbers (2n) for 17 rare, endemic plant species (25 populations) from the families: Alliaceae, Apiaceae, Asparagaceae, Asteraceae, Fabaceae, Linaceae, Papaveraceae, Valerianaceae are reported on the material from the Republic of Buryatia. For Allium udinicum Antsupova (2n = 16) the chromosome complement was examined for the first time. Chromosome numbers of Allium vodopjanovae N. Friesen (2n = 16), Ferulopsis hystrix (Bunge) Pimenov (2n = 40), Heteropappus altaicus (Willd.) Novopokr. (2n = 54), Kalimeris integrifolia Turcz. (2n = 36), Saussurea salicifolia (L.) DC. (2n = 26), Caragana pygmaea (L.) DC. (2n = 16), and Oxytropis triphylla (Pall.) Pers. (2n = 16) from Buryatia were determined for the first time. New hexaploid cytotypes for Aster alpinus L. s.l. and Heteropappus altaicus (Willd.) Novopokr. (2n = 54) were studied. For each species the distribution area and published data on karyology are given.
