|phenology=Flowering (Feb–)May–Jun(–Nov).

|discussion=<p>Erigeron oxyphyllus is a member of sect. Pycnophyllum and is set apart from the rest of the section by its cauline leaves, sharply reduced in length distally, and by its more southeastern geographic range (versus the California-centered distribution of the rest of the section).</p>
