Boechera sanluisensis is an asexual diploid hybrid of Boechera fendleri and Boechera spatifolia, described by Patrick A. Alexander in 2015. The only record of it from the Watershed was found by Alexander on a small butte just south of Limekiln Peak (Rio Grande Co, 20 June 2021. It can be distinguished from B. fendleri and B. spatifolia by having a single flowering stem and basal leaves ciliate throughout their length. It is an imperiled plant, so far found in the northern counties of New Mexico bordering Colorado, and in Rio Grande Co, CO. So it is endemic to the upper Rio Grande drainage. The species has only recently been described, so more misdetermined records may exist in herbaria.
