- Rocky Mountain Jacob's-ladder has been fairly often recorded from the Watershed, especially from rocky tundra slopes. Except for 6 reports from New Mexico, Polemonium confertum would be endemic to Colorado. Note, however, that Allred et al. (2020) examined many specimens of P. confertum and P. viscosum from southern Colorado and New Mexico and found that the New Mexico vouchers were intermediate between the two species and that "Most of the plants from southern Colorado called confertum [also] belonged to such intermediates and could easily be referred to viscosum." The New Mexico specimens, determined as Polemonium confertum, were found in the Rio Grande drainage only from Taos Co.
