Notes.

In all eight studied populations of E. tanhoensis , Siberian endemic species, the somatic and basic chromosome numbers are 2 n = 14 and x = 7, respectively (Table 1 View Table 1 ; Fig. 2D-E View Figure 2 ). Five pairs of chromosomes (I-V) are metacentric, two pairs (VI-VII) are submetacentric (Tables 2 View Table 2 and 3 View Table 3 ; Fig. 3 View Figure 3 ). A pair of metacentric chromosomes (II) exhibited a secondary constriction. We found small B chromosomes in plants from two populations (pops 10 and 13). The maximum number of Bs in root tip cells appeared to be 8. They were represented by small metacentric and dot-shaped chromosomes, which are obviously telocentric. The karyotype formula of E. tanhoensis is 2 n = 2 x = 14 = 8m + 2msat + 4sm + 0-8B. Here, we present the results of the karyomorphological analysis of E. tanhoensis from the "Tanhoi Village" population (pop. 12).
