Alberta fleabane, three-lobed daisy
|
| Perennials, 3–15 cm; taprooted, caudices simple or with relatively short and thick branches. |
Perennials, 3–8(–10) cm; taprooted, caudex branches rhizomelike, relatively thick to thin, woody. |
erect, sometimes branched, hirsute (hairs unequal), ± minutely glandular. |
mostly erect, hispido-hirsute, sometimes woolly distally, minutely glandular. |
mostly basal (persistent; petioles prominently ciliate, hairs spreading, thick-based); blades narrowly oblanceolate to spatulate, (20–)30–80 × 2–4(–12) mm, cauline sometimes continuing distally to about midstem, margins entire, usually ciliate, sometimes coarsely so, faces sparsely to densely hirsute, sometimes minutely glandular. |
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. |

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).
