État de la populationTexte officiel évaluation IUCNExpert
In the wild, this species occurs as two cytotypes, which are rather similar to one another and have not previously been recognized (until Ashburner and McAllister 2013). The octoploid cytotype of B. dahurica is common and widespread in continental northeastern Asia including Korea, but the hexaploid is rare and found in Japan and the Kurile Island of Iturup. It has been proposed by Ashburner and McAllister (2013) that the continental octoploid cytotype is recognised as var. dahurica, the Kurile Island and Hokkaido populations as var. okuboi, and the more distinct Honshu populations as var. parvifolia.
