Discussion | Subspecies 2 (2 in the flora). Orobanche parishii is distributed mainly in the southern High Sierra Nevada, Tehachapi Mountains, Central Coast, southwestern California, Desert, Inyo, and White mountains, and Channel Islands. The hosts of Orobanche parishii include several herbs and shrubs of Asteraceae. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Orobanche vallicola is rare but occurs occasionally in widely scattered localities in cismontane California from Trinity County south to Los Angeles County. The most frequently reported host for Orobanche vallicola is Sambucus (Adoxaceae), but O. vallicola has also been reported on Baccharis douglasii and Ericameria nauseosa (Asteraceae), Pyrus (Rosaceae), Quercus agrifolia (Fagaceae), and Symphoricarpos albus (Caprifoliaceae) (L. R. Heckard 1973). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
