| Perennials, 7–25 cm; taprooted, caudices branched. |
Perennials, 5–25 cm; taprooted, caudexlike branches relatively thick, woody. |
sprawling or pendent (branched), hirsute, minutely glandular. |
ascending (without axillary tufts of leaves), glabrous, eglandular. |
cauline; blades cuneate to obovate, 150–400 × 10–20 mm, nearly even-sized to near heads, margins 3-lobed or -dentate (lobes sometimes with shallow secondary lobes or teeth, much narrower than central portion of blades, usually acute), faces hirsute, minutely glandular. |
cauline (all commonly withering early in season); proximal blades oblanceolate to narrowly oblanceolate, 20–50(–100) × 0.5–1(–15) mm, abruptly reduced distally, becoming linear to filiform, mid and distal shorter than internodes, margins entire, usually eciliate, sometimes sparsely ciliate, faces sparsely and minutely strigose or glabrous, eglandular. |

Of conservation concern. Erigeron basalticus is in the Center for Plant Conservation’s National Collection of Endangered Plants. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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).
