Sierra ancha fleabane
|
| Perennials, 5–35 cm; rhizomatous, fibrous-rooted, caudices sometimes branched. |
Perennials 7–22 cm; taprooted, caudex branches relatively thick, short, retaining old leaf bases. |
erect, sparsely and loosely strigose to strigoso-villous, eglandular. |
ascending to somewhat pendent, sparsely strigose to glabrate, eglandular. |
basal and proximal cauline much reduced or present as scales; cauline blades linear to linear-oblong or oblong-lanceolate, 10–30 × 1–5 mm, largest at midstem, then relatively even-sized to peduncles, margins entire, sometimes prominently ciliate, faces glabrous or sparsely villous. |
basal (persistent) and cauline (petioles about 2 times blade lengths); basal blades obovate-spatulate, (30–)40–90 × 3–8 mm, margins entire or with 1(–2) pairs of deep lobes or teeth, faces sparsely ascending-strigose to glabrate, eglandular; cauline blades oblanceolate at midstem, only slightly reduced distally. |
4–6 × 6–12 mm. |
3–3.5 × 5–7 mm. |
20–50; corollas white, less commonly pinkish, or aging pinkish, 4–8 mm, laminae not coiling or reflexing. |
14–36; corollas white, drying white to lavender, 6–8 mm, laminae reflexing. |
3–4.6 mm. |
2–2.8 mm (veins prominently orange-resinous). |
in 2–3 series, loosely and sparsely strigose, eglandular. |
in 3–4 series, (purplish, midveins orange-resinous, slightly swollen) glabrous or sparsely strigose, sometimes sparsely minutely glandular. |
1(–5). |

Variety villicaulis, from Anticosti Island (Quebec) and Newfoundland, has been distinguished on the basis of its relatively shorter stature (mostly 3–15 cm) and greater ratio of peduncle to leafy-stem lengths (stems and peduncles as long as or longer than the leafy parts of stems); the distinction appears to be arbitrary.
