Of conservation concern. Senecio warnockii is infrequently collected; additional study may show it to be an edaphic phase of S. flaccidus. The restriction to gypseous soils and the gross aspect combine to make it distinctive. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Senecio scorzonella is restricted to high elevations in the Sierra Nevada–Cascade uplift and the White Mountains of California; it barely enters adjacent Nevada. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
