nw North America, Asia (Bhutan, China, Nepal, Russian Far East).

Discussion

Species 2 (1 in the flora).

Boschniakia has not been well studied using modern systematic techniques. The overall relationship of the genera of holoparasites in Orobanchaceae is currently under review.

Boschniakia himalaica Hooker f. & Thomson is distributed in southern China and the Himalayan countries of Asia. It is parasitic on species of Rhododendron.
