leafy daisy, leafy fleabane
|
| Perennials, 2–20 cm; slenderly taprooted, caudices usually branched. |
Perennials, 20–100 cm; taprooted, woody, with caudexlike branches 2–15 cm, or leafy stems arising directly from roots; single plants usually bowl-shaped, with up to a 65 cm lateral spread. |
usually decumbent-ascending, moderately to densely hirsutulous to hirtellous (hairs usually deflexed), eglandular. |
erect or ascending (often purple, distal branches stiff, spreading-ascending, without axillary leaf tufts), glabrous or sparsely strigose (hairs straight, ascending-appressed), sometimes minutely glandular distally. |
basal (persistent) and cauline; basal blades 1-nerved or weakly 3-nerved, spatulate, rhombic-elliptic to obovate or oblanceolate (often folding), 20–50(–80) × 3–10(–13) mm; cauline gradually or abruptly reduced and linear distally (bases abruptly contracted to petioles), margins entire, faces moderately to densely hirsutulous, eglandular. |
cauline; blades 1-nerved (often sharply folding in narrower forms), filiform or linear to oblanceolate, 10–65 × 1–5(–10) mm, relatively even-sized (mid and distal longer than internodes), margins entire, ciliate (cilia ascending-appressed, thick-based), faces glabrous or sparsely strigose, eglandular. |
5–9 × 7–14 mm. |
3.2–6.5 × 7–12(–14) mm. |
10–25; corollas deep blue or violet to rose-purple, 5–10 mm, laminae not coiling or reflexing. |
15–60; corollas white to blue, 5–15 mm, laminae not coiling or reflexing. |
4.2–6.3 mm. |
3.5–5.5 mm (throats slightly indurate, not inflated). |
in 3–4 series (tips and margins often purple), sparsely to moderately hirsutulous, densely minutely glandular. |
in 3–5 series (outer: margins stramineous, with distal, greenish, rhomboid patches; inner: margins narrow, scarious), glabrous or moderately to densely strigoso-hirsute, sparsely and obscurely to densely and prominently minutely glandular. |
1(–2). |
1 or 2–5 in loosely corymbiform arrays. |
2.5–3.1 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 20–30 bristles. |
(1.8–)2.2–3 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 19–34 bristles. |

Erigeron asperugineus sometimes is very similar in aspect to E. clokeyi var. pinzliae; the latter differs in its narrower leaves, coarsely ciliate petioles, broader and non-reflexing rays, and shorter cypselae. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Varieties 5 (5 in the flora). Erigeron foliosus and its close relatives, including varieties, were mapped in detail by G. L. Nesom (1992b). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
