Known only from the Clark and Kingston mtns. Similar to M. arizonica, M. boydii, M. linoides, M. mojavensis, and M. robisonii; needs further study to indicate its relationship to these other taxa. Intergrades extensively with M. linoides ssp. sierrae and M. odoratissima ssp. glauca in the northern part of its range. See Novon 19:315-343 (2009) for original description.
