YES Rich Haswell: Saguache Co, rhyolite seep by Hwy 114 12.7 miles W of Saguach 17 July 2016

Comments

In the Watershed, curlycup gumweed has usually been recorded from the Upper and Lower Basin, in dry and sometimes disturbed terrain, but occasionally it has been found at higher elevation, e.g., in the San Luis Hills and along Hwy 114 west of Saguache. A recent observation was just off Hwy 160 a mile west of Alamosa (iNaturalist #184339746, 2023). BONAP and FNA subsume Grindelia nuda as a variety of G. squarrosa, but Ackerfield follows G. L. Nesom (1990) in affording it species rank. SEINet vouchers of this species or variety record it from the Rio Grande drainage as far south as the Big Bend country of Texas.
