Plants loosely cespitose, 4–31 cm; taproots branched, poorly developed. Stems villous to lanate, eglandular or densely stipitate-glandular. Leaves basal; petioles slender; blades 3-nerved, linear to narrowly oblanceolate or spatulate, 24–70(–100) × 1.5–9 mm, pliable (abaxial faces ± plane), bases attenuate, margins eciliate, eglandular, apices acute to obtuse, faces villous to lanate (trichomes multicellular), or glabrous adaxially, and/or stipitate-glandular. Heads borne singly. Peduncles 20–155 mm, usually lanate at least immediately proximal to heads, sometimes stipitate-glandular. Involucres broadly campanulate to hemispheric, 13–28 × 9–15 mm. Phyllaries 18–37(–64) in 2–3 series, 1- or 3-nerved, scarcely unequal, outer lanceolate to narrowly oblong, 7.5–11.5 × 1–3 mm, mid and inner lanceolate, 8–12.5 × 1–4 mm, proximally rather indurate, distally herbaceous and pliable, margins scarious, sometimes broadly so, often fimbriate, wholly green except for margins or with narrow green portions longer than broad, apices acute to acuminate, abaxial faces villous and/or stipitate-glandular. Ray florets 9–17; laminae elliptic, 8–14 × 2.5–7 mm. Disc florets 30–45(–57); corollas funnelform to narrowly vase-shaped, 5.5–8.5 mm, tubes sparsely hairy, lobes 0.7–1.4 mm, ca. 1 /8 – 1 / 6 length of corollas; anthers 2.5–3 mm, style-branch appendages subulate to broadly lanceolate, 0.6–1.4 × 0.7 mm, stigmatic lines 0.6–1.8 mm, lengths nearly 2 times appendages. Cypselae 2.5–5(–6.5) mm, lengths 2 / 3 disc corollas, faces thinly sericeous; pappus bristles 40–50, 5–9.5 mm, nearly equaling to slightly longer than disc corollas.

Stenotus lanuginosus

provided by wikipedia EN

Stenotus lanuginosus is a species of flowering plant in the family Asteraceae known by the common names woolly mock goldenweed[1] and woolly stenotus.

Distribution

The plant is endemic to the western United States, especially the Great Basin region of the inland Pacific Northwest, northeastern California, and northern Nevada. It grows in cold, dry regions such as sagebrush plateau and high mountain slopes in subalpine and alpine climates.

Description

Stenotus lanuginosus is a perennial herb usually forming a compact tuft of herbage with a fibrous root system. The leaves are linear to widely lance-shaped leaves and measure up to 10 centimeters long. They are coated in white woolly fibers and are generally glandular.

The inflorescence is a solitary flower head with woolly or hairy green phyllaries. The flower head contains yellow disc florets and several yellow ray florets, each about a centimeter long.
