Discovered in CA by Alison Colwell in the vicinity of Yosemite NP. Potentially threatened by hydrological alterations caused by logging activities. Easy to identify due to two nearly identical sporophores and no trophophore; other Botrychium spp. will occasionally produce a spore-bearing trophophore, but the two leaf segments are generally not identical. Not in The Jepson Manual (1993). See American Fern Journal 71(1):20-30 (1981) for original description, and 85(4):375-394 (1995) for taxonomic treatment.
