YES Rich Haswell: Rio Grande Co, Del Norte, 10 July 2021 See Annotated Page

Comments

Although the plant is frequently collected in the San Juans west of the Divide, it is poorly represented from the Watershed—less than ten collections from foothill and low montane locations on both sides of the Valley. Note that C. atrovirens is difficult to distinguish from other Chenopodiums, such as C. hians, C. desiccatum, and C. pratericola. In the USA it is present in all Western states, and follows the Rio Grande drainage—with scattered observations—down through New Mexico to the Big Bend country of Texas.
