Discussion
Petrorhagia nanteuilii is known from two counties in northern California (first collected in 1956) and a single site in British Columbia. It may be an alloploid derived through hybridization between P. prolifera and P. dubia; recent attempts at crossing the latter two have failed (S. M. Thomas and B. G. Murray 1983).
