Comments

There are about ten Watershed vouchers of stinky goosefoot, from basic to lower montane on both sides of the Valley; e.g., near Antonito (Conejos Co, 1910); Cottonwood Spring NNW of Saguache (Saguache Co, 1999); Baca Grande Subdivision near Creston (Saguache Co, 2014). Chenopodium watsonii is probably more common than this record suggests. It is especially adept at occupying over-grazed and other disturbed ground, sometimes urban. The photoecord near Del Norte would add Rio Grande to counties indicated in Ackerfield (2022) and BONAP (2022). Chenopodium watsonii is based chiefly in Arizona, New Mexico, Wyoming, and Colorado, with outlying locations in California, Nevada, Utah, and Montana. In New Mexico, it follows the Rio Grande drainage to the Border with Mexico, but the distribution follows the drainage no farther. Note that C. watsonii is not the only goosefoot potentially in the Watershed malodorous to human noses (e.g., C. neomexicanum).
