- Comments
- Amauriopsis dissecta is a very common mid-to-late summer asterid, throughout the Watershed, preferring open dry montane slopes but growing beside Basin roads and streets (e.g., Mosca, Alamosa Co). A colony has been thriving on the side of a gravel driveway in Del Norte for 18 years. The center of the USA distribution is the Four Corners, with presence in Utah, Arizona, Colorado, and New Mexico, as well as parts of southern California, Nevada, Wyoming, and the Black Hills of South Dakota. It follows the Rio Grande drainage through New Mexico on to the Big Bend country of Texas. Note that Baldwin and Wood's 2016 revision of the genus Bahia once again renamed this plant, putting it into the segregate genus Hymenothrix. As yet BONAP and FNA have not accepted this revision, but iNaturalist has.
