Additional images of flat-topped broomrape as seen on dry slopes of Arizona Creek about one-third of a mile downstream of where the road crosses the creek in the Pueblo Mountains of southeastern Oregon...........June 1, 2012. Note the thick base of the plant, numerous tightly clustered flowers (typically more than 20), the flat top to the inflorescence and the long, short pedicels (so this can't be O. fasciculata) slender calyx lobes. Unfortunately, I wasn't able to get a good frontal view of a flower during this visit.
