silver fleabane, silvery daisy
|
| Perennials, 15–60 cm; rhizomatous, fibrous-rooted, caudices or primary rhizomes slender, simple or branched, usually producing slender, herbaceous, scale-leaved stolons bearing terminal leaf tufts. |
Perennials, (8–)15–30(–40) cm; taprooted, caudices branched, retaining old leaf bases. |
erect to ascending, usually glabrous, sometimes sparsely hirsuto-pilose proximal to heads, densely minutely glandular to nearly eglandular. |
erect, densely gray-green to silvery-strigose (hairs white, closely appressed), eglandular. |
basal (persistent) and cauline; basal blades spatulate to elliptic-spatulate (to oblanceolate-obovate), 30–150 × 9–35 mm; cauline gradually reduced distally (bases usually clasping to subclasping), margins entire or serrulate to mucronulate with 3–5 pairs of teeth, faces glabrous, distal often glandular. |
basal (persistent) and cauline (leaf bases broadened or not, not thickened and whitish-indurate); basal blades spatulate to oblanceolate or narrowly oblanceolate, (15–)20–50(–70) × 1–4(–6) mm, margins entire, faces silvery-strigose, eglandular; cauline blades linear to linear-oblanceolate, much reduced distally. |
