Notes Glossary
  • Single population rediscovered in Chino in 2011. Previously considered extinct since 1999. Threatened by transmission line development, housing development, and urbanization. Potentially threatened by hydrological alterations, weeding, and herbicide application. Historical occurrences presumed extirpated by wetland modification and urbanization. Does not key out correctly from ssp. limnophila in TJM (1993) and TJM 2. See Bulletin of the California Academy of Sciences 2:417 (1887) for original description, and Madroño 59(1):25-27 (2012) for information on rediscovery.
