Geiser's fleabane
|
| Perennials 5–15 cm; rhizomatous, fibrous-rooted, caudex or rhizome branches relatively short and thick. |
Annuals, 5–40 cm; slenderly taprooted, caudices simple. |
basally ascending, sparsely villous to pilose, minutely glandular. |
erect (herbaceous), sparsely spreading- to deflexed-villous proximally, sparsely strigose (hairs straight) distally, eglandular. |
mostly basal (persistent; petioles equaling or longer than blades); blades spatulate to oblanceolate-spatulate, 10–50 × 4–12 mm, cauline abruptly reduced distally, margins entire (apices rounded), faces sparsely hirsute or glabrous, eglandular. |
basal (usually not persistent) and cauline; basal blades oblanceolate to subspatulate, 15–60 × 4–11 mm; cauline gradually reduced distally (sometimes barely subclasping), margins entire or with 2–4 pairs of teeth or lobes, faces hirsute, eglandular. |
6–8 × 10–15 mm. |
2.5–3.5 × 5–7 mm. |
25–40; corollas white, 7–10 mm (mostly 1–2 mm wide), laminae coiling tardily. |
44–70; corollas white, drying white to pink, 3–6 mm, laminae not coiling or reflexing. |
3.5–4.5 mm. |
1.2–1.6 mm (throats slightly indurate and inflated). |
in 2–3(–4) series (purplish throughout or at margins and tips), hirsute to hirsuto-villous (hair cross walls clear or reddish to reddish purple), minutely glandular. |
in 2–3 series, sparsely hirsute, sometimes minutely glandular. |
1. |
1–20 in diffuse arrays (branches from midstem distally, peduncles often dilated near heads). |
2–2.8 mm, 2-nerved, faces strigose; pappi: outer of setae, inner of 15–20 bristles. |
0.7–0.9 mm, 2-nerved, faces sparsely strigose; pappi: outer of scales, inner of 9–11 bristles. |

Erigeron flettii differs from E. grandiflorus in having fewer, wider, consistently white rays, broadly spatulate basal leaves with bases constricted into narrow petioles longer than the blades and apices rounded or obtuse, less dense involucral vestiture, and strongly barbellate pappus bristles. It is known only from the Olympic Mountains. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erigeron geiseri is characterized by its annual duration and slender taproots, relatively small size, lobed basal leaves, peduncles often dilated near the heads, obovate phyllaries with broad, scarious margins, and relatively small disc florets and cypselae, the latter with pappi of conspicuous scales and relatively few bristles.
