Of conservation concern. Senecio quaylei resembles S. ampullaceus; it is more robust and glabrous, and has prominently clasping mid-cauline leaves. The size and robustness suggest that it may be a polyploid derivative of S. ampullaceus. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
