|discussion=<p>Subspecies coronaria occupies the widest range of habitats of any annual stephanomeria, and it shows striking morphologic variability for some characters including number of florets, lengths and widths of corollas, numbers and plumosity of pappus bristles, and degree of “bumpiness” of faces of the cypselae. Populations from the eastern slopes of the Sierra <i>Nevada</i> in California to the mountains of <i>Nevada</i>, central Oregon, and Idaho vary most evidently toward <i></i>subsp.<i> exigua</i>, native to the deserts, in having heads on longer peduncles, making a quite different architectural appearance than characteristic of the plants with nearly sessile heads in the Coast Ranges and elsewhere in California. The variation in <i></i>subsp.<i> coronaria</i> presumably results from hybridization with <i></i>subsp.<i> exigua</i> where the two subspecies make contact at intermediate elevations. Hybrid individuals are readily identifiable wherever <i></i>subsp.<i> coronaria</i> makes contact with other subspecies of <i>S. exigua</i> (L. D. Gottlieb 1971, 1972).</p>
