- NEED IN SITU PHOTOS. Following BONAP and POWO as of 2025, this inventory treats swordleaf rush (Juncus ensifolius) and Rocky Mountain rush (Juncus saximontanus) as two separate species. FNA distinguishes the two taxa as follows: Juncus ensifolius (sensu stricto) has three stamens; Juncus saximontanus (under the synonym Juncus ensifolius var. montanus) has six stamens. Juncus ensifolius has been vouchered under that name a fair number of times from both sides of the Watershed, but most of their specimens are probably Juncus saximontanus. BONAP shows a Watershed distribution of only Mineral Co for J. ensifolius, and the data above accepts that. There are then four Watershed locations for Juncus ensifolius, all fairly close geographically: Wolf Creek pass (Mineral Co, 1918); Willow Creek west of Creede (Mineral Co, 2004); Pool Table Road north of Wagon Wheel Gap (Mineral Co, 1989); and six miles south of Wagon Wheel Gap (Mineral Co, 2013). The USA distribution of J. ensifolius is all Western states except for New Mexico, so the few Watershed locations may be the only ones for the entire Rio Grande drainage. Note that Ackerfield (2022) treats J. saximontanus as a synonym for J. ensifolius.
