( A. subpolaris Boriss. & Schischkin ):

Calyx-teeth | as long as tube. Corolla purplish-violet; keel c. 1 mm shorter than both standard and wings. Legume 8-11 mm, ovoid, often with septum reaching | way across. 2n= 16. Arctic Europe. The differences between the subspecies are much more distinct in E. European Russia than in Fennoscandia, where there is less satisfactory correlation of characters.
