Phenology: Flowering Jun–Sep.

Ariz., Calif., Idaho, Mont., Nev., N.Mex., Oreg., Utah, Wash., Wyo.

Discussion

Subspecies corymbosa is most often mistaken for Orobanche californica with which it was formerly associated taxonomically. The two species are very similar morphologically; Orobanche corymbosa, with only two subspecies, has much less morphological variability. Except for a small area of sympatry in eastern California, the two species are otherwise allopatric.
