Notes

Disjunct occurrences in SIS and TRI counties may be taxonomically distinct from transmontane plants; currently under study. On watch list in NV. Probably related to both P. eximium and P. elegans. See Fremontia 22(2):24-26 (1993) and Madroño 45(3):200-209 (1998) for information about ongoing biosystematic study.
