hairy daisy, woolly daisy, woolly fleabane

needle-leaf fleabane

Habit Perennials, 2–5 cm; taprooted, roots sometimes barely evident, caudices diffuse, with extensive systems of rhizomelike, relatively long, slender branches. Perennials, 4–18 cm; taprooted, caudex branches relatively short, thick.
Stems

erect (simple, ± scapiform), finely and loosely villous, minutely glandular.

erect (greenish), usually closely appressed-strigose, sometimes glabrate, eglandular.

Leaves

basal (persistent);

blades oblanceolate to oblong-oblanceolate, 5–25(–30) × 2–5 mm, strongly reduced distally, margins usually entire, smallest and earliest usually 3-toothed or -lobed apically (lobes or teeth acute), ultimately entire, finely and loosely lanate-villous, eglandular.

mostly basal or basal (persistent, persistent portion relatively long and slender-fibrous) and cauline (greenish);

basal blades 1-nerved linear to linear-oblanceolate or oblanceolate or narrowly spatulate, (20–)30–80 × (0.5–)1–3 mm;

cauline reduced distally (bases attenuate, not thickened and whitish-indurate) margins entire (apices obtuse or rounded), faces abaxially glabrous or glabrate, adaxially sparsely strigose, eglandular.

Involucres

9–13 × 12–23 mm.

(3.5–)4-–6.5 × (5–)6–13 mm.

Ray florets

30–80;

corollas white or purplish, 8–11 mm, laminae not coiling or reflexing, spreading.

15–55;

corollas white to pink, 4–8 mm, laminae coiling.

Disc corollas

5–6.5 mm.

(2.8–)3.5–4.3 mm.

Phyllaries

in 2–3 series (purple or purple-tipped), moderately to densely, finely and loosely villous (hairs sometimes with purple cross walls), minutely glandular.

in 2–4 series (greenish or sometimes purple, margins thickened), strigose to loosely strigoso-hirsute, sometimes more densely so on distal 1/3, sparsely minutely glandular.

Heads

1.

1(–3 rarely, from branches at midstem).

Cypselae

3.5–4 mm, 2-nerved, faces finely hirtellous to glabrate;

pappi: outer of setae, inner of 25–35 (whitish to tawny) bristles (often twisted).

2.2–2.9 mm, 2-nerved, faces and margins villoso-hirsute, sometimes more densely so on nerves;

pappi: outer of setae, inner of 15–25 bristles.
