Conopholis america is, a parasitic plant, used in herbal medicine for menstrual cramps and other issues. I am using the Latin name here because the most common name here in the South, (“squaw root”) is widely regarded as an offensive word in spite of debate about its origins).
The forest service has taken to calling it “cancer root” in spite of that name being just confusing, for reasons even they point out, due to it not curing cancer. You can read more about it at https://www.fs.fed.us/wildflowers/plant-of-the-week/.
I saw them frequently at Mount Pisgah Campground near the Blue Ridge Parkway in North Carolina, which is where I took this picture in June.
