Discussion
Subspecies utahensis is known from extreme northeastern Nevada (Elko County) and western Utah. P. H. Raven (1962, 1969) described this subspecies for populations that are somewhat intermediate between Chylismia walkeri subsp. tortilis and C. scapoidea subsp. brachycarpa, suggesting that this entity perhaps developed via hybridization between them. The ranges of the two putative parents heavily overlap that of subsp. utahensis. A. Cronquist et al. (1997c) combined subsp. brachycarpa and subsp. utahensis.
