Golden Smoke (Corydalis aurea)
Location: Grand County, Colorado, USA
The brightly colored wildflower is widely distributed across the continental United States. The plant is a member of the Fumariaceae (Fumitory) family. I photographed this example in a meadow in Grand County, Colorado.
According to the botanical reference website eFloras.org:
The Navaho used Corydalis aurea medicinally for a variety of ailments, including rheumatism, diarrhea, sores on the hands, stomachaches, menstrual problems, and sore throats, and as a general disinfectant (D. E. Moerman 1986, no subspecies cited).
