Discussion

Variety ambigua is highly variable among populations. Much of the variation tends towards two ecotypes. One ecotype has thin leaves with narrow, often acute lobes and more or less spreading-ascending stems. Plants of this ecotype inhabit sandy coastal bluffs and short-grass, herbaceous meadows, often well inland, in Marin, Napa, and Sonoma counties in California. Plants of a second ecotype have fleshy leaves and bracts with more or less obtuse lobes and more upright stems. These are found in Salicornia-dominated coastal salt marshes and range from southern Vancouver Island to San Francisco Bay. Plants found around Tomales Bay, Marin County, may have pink beaks. Variety ambigua occasionally hybridizes with Castilleja exserta and reportedly with C. rubicundula.
