- From the Watershed Alyssum desertorum has one vouchered location, “roadside weeds” in Fort Garland (Costilla Co, 2003). Beyond this, recent photorecords locate a street side in Del Norte (Rio Grande Co, 2015), a restaurant parking lot in South Fork (Rio Grande Co, 2017, 2019, 2021), a gravel-road turn-out a couple of miles N of South Fork (Rio Grande Co, 2021), and a street side in Alpine Village NE of South Fork (2021—the last being iNaturalist observation 79801507, by Erika Martin. These occurrences would add Rio Grande CO to the Watershed distribution indicated by Ackerfield (2022) and BONAP (2022). Possibly the species is a latecomer to the Watershed. Or perhaps it is more wide spread there, just not recognized or collected. The few records in the Rio Grande drainage of northern New Mexico mark the southeastern limit of the USA distribution of this exotic alyssum.
