- Comments
- There are only three herbarium vouchers for Solanum rostratum from the Watershed (1982-1994): Mineral Hot Springs (Saguache Co); south of Alamosa (Alamosa Co), and east of Antonito (Conejos Co). Yet recently photorecords add to the picture. In Del Norte plants have persisted by town streets for five years (2019-2024). iNaturalist observations document occurrences on Sept 2018 (Hwy 15 south of Monte Vista, Rio Grande Co), in Aug 2021 (12 miles east of Alamosa, Alamosa Co), and Aug 2023 (Hwy 285 north of Center, Saguache Co). Neither BONAP (2023) or Ackerfield (2022) show the species present in the Watershed. Currently, however, POWO, under the name Solanum angustifolium, shows it native to all lower USA states except for Florida (October 2026). It follows the Rio Grande drainage through New Mexico and Texas to the Gulf of Mexico.
