A common climber in the Hazara and Kashmir areas, found from 1000-2000 m.

A collection from Mansera (R.R. & I.D. Stewart 2556, RAW) and Kashmir (R.R. & I.D. Stewart 17337, RAW) has linear lanceolate leaves, c. 10 times as long as wide, together with normal leaves which are c. 2½ times as long as wide. This variation in leaf size is most likely environmental.
