Comments: Compared to Blitum capitatum subsp. capitatum, Blitum capitatum subsp. hastatum has smaller glomerules and tepals greenish and not fleshy at maturity. It has been sparsely vouchered from the Watershed (usually under the old name of Chenopodium overi), from both sides of the Valley although mostly from the west side: e.g., on Willow Lake Trail east of Crestone, 1999), near Baldy Mountain 15 air miles SW of Creede (Mineral Co, 2003), near Spectacle Lake (2004, Conejos Co), Deep Creek trailhead, SW of Creede (2004, Mineral Co), on the Rio Chama (Archuleta Co, 2004), Pinyon Flat cpgd in the Great Sand Dunes NP (Saguache Co, photorecord, 2016, and Beaver Creek cpgd SW of South Fork, photorecord, 2020). Blitum capitatum is common in the western states of the USA, and across the states bordering Canada. The subspecies capitatum follows the Rio Grande drainage through New Mexico but no farther. Note that some authorites (e.g., Ackerfield 2022) treat these subspecies or varieties as species: Blitum capitatum and Blitum hastatum. Both are found in the Watershed.
