Senecio wootonii reaches its southern limit in Coahuila and Chihuahua, Mexico; farther south, it is replaced by S. toluccanus de Candolle, a similar, larger, more robust species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
