Notes: Need confirmation of SCT Isl. occurrences. Many ORA Co. occurrences recently extirpated. Many historical occurrences also extirpated; need information. Population fragmentation a serious problem, and plant continues to be threatened by urbanization, vehicles, development, foot traffic, grazing, habitat disturbance, and competition from non-native plants. A synonym of Hemizonia parryi ssp. australis in TJM (1993). See MadroƱo 3(1):15 (1935) for original description, and Novon 9:462-471 (1999) for revised nomenclature. |
