Description
Taxonomy
The species epithet rhypara ("grimy" in Greek) is derived from its dusty appearance and from its discoverer, James W. Grimes.[4][5]
There are two varieties of this plant. The var. rhypara grows on barren tuff and var. shellyi grows in rock cracks and crevices on pumice and tuff.[2] When the plants grow in rock fissures they sometimes appear to be lined up in rows.[5] Associated plants include Purshia tridentata, Poa sandbergii,[2] Gilia congesta, Sitanion hystrix, Scutellaria nana, and Eriophyllum lanatum.[4]
Threats
Threats to this species, particularly var. rhypara, include gold mining, as the habitat contains gold deposits. Other threats include cattle, off-road vehicles, fire suppression, and loss of pollinating insects.[5]
