Annuals, 15–40 cm; slenderly taprooted. |
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. |
initially erect, later ascending to decumbent (herbaceous), proximally spreading- to deflexed-villous, closely to loosely strigose on distal 1/3–1/2, eglandular. |
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 (often drying translucent, often withering by flowering) and cauline; basal (thin) blades oblanceolate to obovate or spatulate, 10–80(–140) × 5–34 mm, cauline slightly or gradually reduced to distal 1/3 of stems (bases clasping), margins usually with 1–4 pairs of teeth or lobes, sometimes entire, faces sparsely short-hirsute to hirsuto-villous, eglandular. |
3.5–5 × 7–12 mm. |
2.5–3 × 5–10 mm. |
70–150; corollas white, drying white, (2–)6–15 mm, laminae reflexing. |
95–160(–250); corollas white to bluish, 2.5–4 mm, laminae not coiling or reflexing. |
2.5–3.3 mm (throats somewhat white-indurate, not inflated). |

in 3–4 series, strigose to hirsute (hairs arising mostly from midregion), usually minutely glandular, rarely eglandular. |
in 2–4 series, hirsute to sparsely villous, minutely glandular. |
(1–)5–15(–30) in loosely corymbiform arrays. |
(1–)3–10(–20) in diffuse arrays (branches from distal 2/3). |
1–1.3 mm, 2(–4)–nerved, faces sparsely strigose; pappi: (outer 0) inner (readily falling) of (8–)10–12 bristles. |
0.6–0.8 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 10–13(–15) bristles. |

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.) |
