About Pteryxia terebinthina (Hook.) J.M.Coult. & Rose
Pteryxia terebinthina (Hook.) J.M.Coult. & Rose, also classified under the synonym Cymopterus terebinthinus, is a perennial herb belonging to the carrot family, Apiaceae. Its common names are Aromatic spring-parsley, northern Indian parsnip, and turpentine cymopterus. This species has parsley-like leaves and is native to the Great Basin region of the American West. It grows on dry, sandy or rocky slopes, most often near rock outcrops, at elevations ranging from 5,000 to 9,000 feet (1,500 to 2,700 m). It occurs within sagebrush steppe and montane plant communities across the Great Basin, and has been documented in the Toiyabe Range and Deep Creek Mountains. Ecologically, Pteryxia terebinthina acts as a host plant for the butterfly Papilio indra. Some Plateau Indian tribes have used its roots by chewing them to treat colds and sores.
