Discovered in Chino in 2011; originally identified as C. sepium ssp. binghamiae. All recent occurrences are in irrigated landscapes; historically known from natural wetlands and marshes. Historical occurrences in LAS Co. should be searched for; needs field surveys. Threatened by transmission line development, housing development, and urbanization. Potentially threatened by hydrological alterations, weeding, and herbicide application. Not in TJM (1993) or TJM 2. See Madroņo 59(1):25-27 (2012) for information on discovery (as C. sepium ssp. binghamiae), and Phytokeys 32:1-26 (2013) for original description.
