Comments

Alpine avens has been frequently collected, in rocky subalpine and alpine habitats, from all mountain regions of the Watershed. In the USA, it is basically a Rockies and Intermountain plant, and follows the Rio Grande drainage almost to the Mexican border. Note that when the petals fall the bracts remain and resemble petals. The variety in the Watershed, var. turbinatum, is sometimes treated on the species level.
