NEED IN SITU PHOTOS. In the Watershed, Dudley's rush has been vouchered only once: in the Rio Grande floodplain north of Monte Vista (Rio Grande Co, 1774). Ackerfield (2022) accepts this record but BONAP (2025) does not. In the USA, the species grows in all states except for Louisiana, Mississippi, and Florida. In terms of distribution, there may be good reason to accept the Rio Grande Co voucher. Juncus dudleyi has been recorded from Colorado counties on both sides of the Watershed, and it follows the Rio Grande drainage solidly through New Mexico and on down through Texas to the Big Bend region. The 1974 voucher could us a review.
