It must be pointed out that Oxytropis immersa (Baker ex Aitch.) Bunge ex Fedtsch. is very variable in the size of the plant, length of leaves, leaflets and peduncle. The extreme forms look so very different from each other that one would not hesitate to put them in different species, but in all the characters specified above the variation is so gradual that it is almost impossible to draw a line, except by using the characters of the stipules. I even debated placing these plants under Oxytropis mollis Royle ex Benth., but the present arrangement is considered more reasonable. Lumping all the forms together would have resulted in a very heterogeneous type of assemblage.
