Comments

For Helianthella uniflora, Ackerfield (2022) shows only counties in the NW corner of Colorado. BONAP (2022) indicates Conejos Co, as well as San Juan Co, without vouchers in SEINet. So the photorecords (2014-2021) from La Manga Creek would add Conejos Co to the distribution of Ackerfield (2022). Note that Ken Heil records a 2006 collection from Archuleta Co only 7 miles west of the Continental Divide, and Allred et al. (2020) shows Rio Arriba Co of New Mexico, bordering the Watershed. These locations would lie at the SW corner of the plant's USA distribution. Helianthella uniflora is wide spread in all USA Western states except for California.
