Most reliable occurrence is at and near type locality near Borax Lake, which may include the only true representatives of this taxon. Plants from COL, GLE, TEH, and southern SHA cos. may be attributable to E. brandegeeae, E. tracyi or undescribed taxa; needs study. Includes E. tracyi in TJM (1993); does not include E. tracyi here. See Madroño 8(3):88-89 (1945) for original description, and Madroño 55(1):82-87 (2008) for additional taxonomic information. |
