- Comments
- Dieteria bigelovii is a very common late summer asterid all around the Watershed, blooming into the fall, often found along roads or in other disturbed ground. Our species is D. bigelovii var. bigelovii (in the past usually treated as Machaeranthera biglovii). Note that where D. bigelovii and D. canescens are sympatric, and that includes the Watershed, they may hybridize (USDA). To distinguish the two species, the safest character is leaf width (D. bigelovii 5 mm or wider, D. canescens 5 mm or less). D. bigelovii is a Southwestern flower recorded from Arizona, Utah, New Mexico, Colorado, and one county in southeast Wyoming. Although not yet vouchered from the Culebras, it is frequently recorded from their extension into New Mexico, where it follows the Rio Grande drainage down to the Mexican border but no farther.
