|discussion=<p>James Allison (in protologue) suggested that <i>Silphium</i> perplexum is a hybrid between <i>S. glutinosum</i> and <i>S. integrifolium</i>. It has glandular hairs on its stems, leaves, and phyllaries as in <i>S. glutinosum</i>; it is also found on chalk, has taller stems, larger leaf blades, and deeper yellow corollas. Further study is needed to determine its status.</p>
