Perennials, 7–25 cm; taprooted, caudices woody, branches usually vertical or horizontal (2–10 cm), sheathed by persistent leaf bases. |
erect, moderately to densely strigose (hairs appressed to ascending, 0.1–0.8(–2) mm, sometimes spreading at bases or throughout), eglandular or glands minute, non-capitate. |
erect, sparsely to moderately hispidulous to hirsute, minutely glandular to stipitate-glandular. |
basal (sometimes persistent) and cauline; blades oblanceolate, margins usually deeply pinnatifid (lobes in 2–5 pairs), sometimes dentate to entire, faces strigose, eglandular; basal 10–60 × 6–35 mm, cauline gradually reduced distally. |
basal (persistent) and cauline; basal blades sometimes 3-nerved, broadly oblanceolate to obovate or spatulate, 20–90(–120) × 5–25 mm, margins entire or denticulate, faces moderately hirsuto-villous, stipitate-glandular; cauline blades smaller, narrower, relatively even-sized distally (bases subclasping). |

Relatively large, pinnatifid leaves are typical of Erigeron neomexicanus; plants with nearly entire leaves can be identified by the strongly perennial habit, white, reflexing rays, and 10–12 readily falling pappus bristles. Erigeron neomexicanus and E. oreophilus were treated by A. Cronquist (1947) as varieties of one species, and their morphologic similarity and the closeness of their geographic ranges support that hypothesis. But relatively few collections are found that could be regarded as intermediates, and both forms sometimes grow in proximity, apparently without a range of intermediates. In some Arizona mountain ranges, apparently only one or the other taxon occurs. Still, the possibility exists that these are populational segregants of a single species (see further comments in G. L. Nesom 1989d). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
