Common in the northern areas of Pakistan from 1540-3048 m. A variable species, especially in Europe, but fairly homogeneous in Pakistan. Distinguished by its many nerved, inflated calyx. Sometimes confused with Cucubalus baccifer due L. due to a similar inflated calyx in the flowering stage, but differentiated by its bifid, not multifid petal limb, and usually glabrous leaves and stems.
