Chromosomes at prophase and metaphase in five individual plants of Spiranthes amoena (M. Bieb.) Spreng collected in a little wet area in Buryat Republic: near Solzan River, 8 km up along the left side of the River from the bridge of the Irkutsk were studied. The chromosome numbers of the plants studied were commonly counted as 2n=60, doubled number of chromosomes of S. sinensis. The karyotype at prophase was 2n=60=40h+16he+4e followed Tanaka's system (1969) suggested that those plants should be treated simply the autotetraploid form of S. sinensis. Thus, plants of S. amoena grown in Buryat Republic could be called as S. sinensis var. amoena (M. Bieb.) Hara.
