|
Mad River fleabane, Mad River fleabane daisy
|
| Perennials 30–80 cm; rhizomatous to subrhizomatous, fibrous-rooted, caudices usually relatively short and few branched, thick, woody. |
Perennials, 10–22(–27) cm, tap-rooted, caudices usually simple, rarely with branches to 20 cm. |
erect, sometimes sparsely pilose (hairs 1–2 mm), densely stipitate-glandular. |
ascending to decumbent-ascending (usually basally purplish), sparsely to densely strigose (basal cells inclined, hairs even-width), eglandular. |
basal (usually withering by flowering) and cauline; basal blades oblanceolate-spatulate, 30–80 × 5–20(–25) mm (bases usually clasping to subclasping), margins entire, faces glabrous, densely stipitate-glandular; cauline blades narrowly lanceolate to oblong-, ovate-, or elliptic-lanceolate, nearly even-sized distally or sometimes mid largest (continuing to immediately proximal to heads). |
basal (persistent) and cauline; blades (strongly to weakly 3-nerved) oblanceolate to spatulate-oblanceolate, 30–100 × (3–)5–12(–14) mm, cauline gradually reduced distally or not, usually continuing to near heads, margins entire, faces hirsuto-pilose to weakly pilose, eglandular. |
6–9 × 10–15(–18) mm. |
(5–)6–7 × 9–12(–14) mm. |
75–150; corollas blue to lavender, 9–17 mm (ca. 1 mm wide), laminae coiling. |
(16–)21–33; corollas white to pinkish or purplish, 10–12 mm, laminae not (or weakly) coiling or reflexing. |
3–4 mm. |
3.2–3.8 mm. |
in 2–3(–4) series, densely stipitate-glandular. |
in 2–3(–4) series, (elliptic- to oblong-oblanceolate, abruptly acuminate), hirsuto-strigose to -pilose, densely villous at bases, usually eglandular, sometimes sparsely glandular. |
1–15(–22) in corymbiform arrays. |
1(–4) (on peduncles 0.5–5 cm), held well beyond leaves at peak flowering, from branches near midstem (or slightly more distal). |
1.7–2 mm, 2-nerved, faces sparsely strigose; pappi: outer of (conspicuous) scales, inner of 14–22 bristles. |
2–2.5 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 16–20 bristles. |

Erigeron vreelandii is similar to E. speciosus in its perennial duration, tall stature, subclasping, spreading leaves nearly even-sized up the stems, corymbiform arrays, and blue rays; it is distinguished by the prominent vestiture of relatively long stipitate-glandular hairs. Intermediates apparently are formed between the two. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
