Oreoxis humilis
Also called Pikes Peak Alpineparsley, Pikes Peak Spring Parsley
Oreoxis humilis, is a rare species of flowering plant in the parsley family known by the common name Pikes Peak spring-parsley. It is endemic to Colorado in the United States, where it is known only from the vicinity of Pikes Peak. There are three occurrences, for a total population of about 4240 individuals.
The plant is threatened by construction and maintenance on the Pikes Peak Highway.
Pikes Peak spring-parsley grows in two Colorado counties, El Paso and Teller, on Pikes Peak. The size of its range is 48 square kilometers (19 sq mi), but the total area occupied by the plant is approximately 225 hectares (557 acres). There are three populations within its range with an estimated 4,240 plants, but the Colorado Natural Heritage Program hypothesized that it may grow in every area above timberline on the mountain in 2001. They grow at elevations of 3,290 to 4,270 meters (10,790 to 14,010 ft).
