Alberta fleabane, three-lobed daisy
|
| Perennials, 15–60 cm; rhizomatous, fibrous-rooted, primary rhizomes relatively slender, producing slender, herbaceous, scale-leaved, stoloniform rhizomes (rhizomes often not collected). |
Perennials, 3–8(–10) cm; taprooted, caudex branches rhizomelike, relatively thick to thin, woody. |
erect to ascending (usually abruptly dilated proximal to heads), villous (more densely so on proximal 1/2), eglandular. |
mostly erect, hispido-hirsute, sometimes woolly distally, minutely glandular. |
basal (persistent) and cauline; basal blades oblanceolate to obovate or suborbiculate, subspatulate, 20–130(–180) × 6–30(–50) mm; cauline gradually reduced distally (bases clasping and slightly auriculate), margins usually dentate to denticulate, rarely entire, faces sparsely to moderately hirsute to hirsuto-villous, sometimes glabrate or glabrous (especially adaxially), eglandular. |
basal (persistent); blades spatulate to obovate-spatulate, 8–30 × 3–6 mm, margins usually 3-lobed, sometimes 2-lobed or entire (lobes 3–8 mm, lanceolate to narrowly ovate or oblong, apices usually acute), ultimately entire, coarsely ciliate, faces hirsute, minutely glandular. |
5–7 × 6–20 mm. |
8–12 × 10–15 mm. |
50–80(–100); corollas light blue to purplish, pink, or white, 6–10 mm, laminae coiling tardily at tips. |
20–40; corollas white to pinkish, 10–15 mm, laminae not coiling or reflexing. |
4.5–6 mm. |
3.5–4.5 mm. |
in 2–3(–4) series, sparsely to moderately hirsute to hirsuto-villous (cross walls not distinctly colored), minutely glandular to stipitate-glandular. |
in 2–3 series (purplish or purple-tipped), hirsute to villoso-hirsute, glandular. |
1–4(–9). |
1. |
1.3–1.8 mm, 2(–4)-nerved, faces sparsely strigose to glabrate or glabrous; pappi: outer 0 or of setae, inner of (22–)28–36 bristles. |
2–2.5 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 15–20 bristles (not twisted). |

Erigeron trifidus has been treated as a synonym of E. compositus; caudex branches of the latter usually are relatively thick and short, compared to those of E. trifidus, which are thinner and are not covered with persistent leaf bases. Leaves of E. trifidus are consistently 3-lobed. Erigeron trifidus was hypothesized (J. G. Packer 1983) to be of hybrid origin (based on its polyploid chromosome number and sterile pollen), with E. lanatus and E. compositus as the most likely parents (based on intermediate morphology and sympatry of the putative parents).
