Oxytropis immersa var. jinaliensis Ali in Kew Bull. 28(2):308. 1973.

Leaves up to 12 cm long, stipules uniformly pilose outside; petiole up to 4.5 cm; leaflets c. 4-10 mm long, c. 1-4 mm broad, ovate-lanceolate to elliptic. Peduncle c. 2.5-30 cm long.

Holotype: Chitral, Shah Jinali Pass, 14000 ft., on open slopes, corolla pinkish purple, 1.8.1958, J.D.A.Stainton 3047 (BM).

Distribution: Chitral.

This variety differs from var. immersa in having the stipules uniformly pilose outside. It resembles Oxytropis mollis Royle ex Benth. and Oxytropis humifusa Kar. & Kir. in the general appearance and habit, however it differs from both of these in having small calyx teeth (less than 2 mm).

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.
