This variety is very closely related to var. Veitchii (Wils.) Bean and 

 seems gradually to pass into it by intermediate forms. Var. davurica 

 is chiefly characterized by rather small glabrous or glabrate leaves dark 

 green above, glaucescent beneath and without conspicuous lateral veins, 

 by the broad and short outer sepals and the conspicuous tuft of white 

 hairs at the end of the stipules, while var. Veitchii has larger leaves more 

 or less furnished with long silky hairs on both sides, dull green above 

 and lighter green and with rather prominent lateral veins beneath, the 

 outer sepals usually about as long as the inner sepals, and it is generally 

 a taller more vigorous plant.
