Sepals c. 3 mm long. Petals twice as long as the sepals. Stamens c. 2.5: 3.5 mm long; anthers c. 1 mm long. Siliquae linear-oblong, 20-30 (-35) mm long, 2-3 mm broad, compressed, usually pilose; valves with a distinct mid-vein; stigma sessile or subsessile, sub-bilobed; septum complete; seeds many, c. 1 mm long.

Fl. Per.: June-July.

Type: N.W. Himalaya, Kunawar, Jacquemont (P, K).

Distribution: W. Tibet, Kashmir, Pakistan and Afghanistan.

A very variable species, showing pilose to almost glabrous habit, exactly the same trend as we find in Christolea crassifolia Camb. Except for slightly broader fruits and narrower fruits respectively C. stewartii (T. And.) Jafri and C. linearis Busch are not different from this species.
