Orobanche californica subsp. grandis
Madroño 22: 60, figs. 1P–R, 3A, 4E. 1973
Phenology: Flowering Apr–Oct(–Nov).
Habitat: Sandy soils or lee of foredunes near coast.
Elevation: 0–150 m.
Subspecies grandis is commonly found near the ocean shore from Los Angeles to San Mateo counties and on Santa Rosa Island. It is uncommon, and its habitat is impacted by Carpobrotus (Aizoaceae) invasions. The primary host is Corethrogyne filaginifolia (Asteraceae), but it can also utilize Grindelia (Asteraceae). Other hosts reported are Adenostoma fasciculatum (Rosaceae), Artemisia, Isocoma veneta, and Heterotheca (Asteraceae).
Plants included in subsp. grandis have been identified variously in the past. The northern coastal specimens were aligned with subsp. californica, whereas the southern collections were identified as subspp. feudgei or jepsonii. Subspecies grandis is roughly sympatric with other coastal subspecies, but its unique morphology and its preferences for sand dune habitat and Corethrogyne filaginifolia as a host make it distinctive.
