Narrative
Collection from a site classified by USDA-NRCS as Major Land Resource Area B10 (Upper Snake River Lava Plains and Hills). Estimated average annual precipitation at the site is 380 mm based on extrapolation from official weather stations at Picabo (20.00 km to the southwest) and Craters of the Moon National Monument (23.75 km to the northeast). Removal of the awn without resultant seed damage has been problematic in Sand Hollow big squirreltail germplasm. Mass of the proximal centimeter of the awn was 0.272 mg at Evans Farm,(Millville, UT) in 2001, 33% lower than Sand Hollow. The less robust awn makes the seed more amenable to debearding. Spike disarticulates in a determinate fashion at the base, unlike most E. elymoides ssp. elymoides accessions that disarticulate indeterminately at each rachis internode.
