NEED IN SITU PHOTOS. Interior rush has been vouchered from only two Watershed locations: "Alamosa," which in Francis Ramaley's loose directions could mean anywhere in Alamosa county (Alamosa Co, 1930), and Baca National Wildlife Refuge (Saguache Co, 2006, 2012). BONAP (2025) also shows Costilla Co. In the USA, Juncus interior is a common and widespread species, documented from all states except those of the Pacific and Atlantic coasts. In Colorado, it has been collected from both east and west of the Watershed. Perhaps the high desert of the Watershed does not suit this rush, which likes low-level moist habitats. Or perhaps it is under-collected in the Watershed, being hard to distinguish from J. confusus and J. dudleyi. J. interior follows the Rio Grande drainage through New Mexico in a scattered way, then carries on down Texas through the Big Bend region.
