S. F. Blake & Cronquist

Leafl. W. Bot. 6: 43, plate 1. 1950.

Common names: Owyhee sage
Endemic
Treatment appears in FNA Volume 19. Treatment on page 531. Mentioned on page 487, 503, 521.

Shrubs, 5–15 (–20) cm (not cespitose), aromatic. Stems relatively numerous, erect, gray, simple (annual flowering branches leafy), loosely sericeous. Leaves (semideciduous) cauline (sessile), gray-green; blades oblanceolate, 0.5–3 × 0.2–1.5 cm (bases attenuate), 3-lobed or irregularly palmatifid (lobes narrow, apices acute), sparsely sericeous-lanate. Heads (mostly erect, peduncles 0 or to 25 mm) in racemiform arrays (4–) 8–12 (–14) × (0.5–) 1–2 (–4) cm. Involucres globose, 3.5–5 × 4–5 mm. Phyllaries ovate, sparsely sericeous. Florets: pistillate 8; bisexual 20–35; corollas yellow (tubular with broad throats), ca. 2 mm, glandular. Cypselae (light-brown) oblanceoloid (4–5-angled, broadest at truncate apices), 0.3–0.5 mm, glandular-pubescent (pappi coroniform, 0.3–0.6 mm, irregularly lacerate).


Phenology: Flowering early spring–mid summer.
Habitat: Rocky swales, dry meadows, alkaline mud flats
Elevation: 1400–2100 m

Discussion

The pappose cypselae make Artemisia papposa anomalous within Artemisia. Artemisia papposa has capitulescence characteristics that suggest a relationship to Sphaeromeria.
