Taxonomic Comments
This record is for the broad treatment of Physaria lepidota which includes the subspecies (sometimes treated as a variety) P. lepidota ssp. membranacea as recognized by O'Kane in FNA (2010, vol. 7). O'Kane (2007) treats it this way, but explains, "It is probable that P. lepidota subsp. membranacea is a stabilized hybrid, perhaps ancient, between P. lepidota subsp. lepidota and one of the infraspecies of P. chambersii. As such, P. lepidota subsp. membranacea could as easily be accommodated as a subspecies of P. chambersii rather than of P. lepidota."
