Description

Key Characters:

Growth Form: Shrub, perennial, erect to 1.5 m tall.

Stems: single-stemmed at base, branching above, round in appearance. Stems sparsely strigose, glandular, resinous.

Roots:

Leaves: Alternate Leaves linear to lanceolate, 3.6–7.3 cm long, 3.7–8.5 mm wide surface strigose, glandular punctate; strigose on midrib on the adaxial surface, more densely so on the abaxial surface; margins strigose subsessile

Flowers: Flowers in open corymbose panicles with (38–)41–57(–71) heads; peduncles 0.5–1.6 cm long, flexuous, covered with strigose hairs. Heads subtended by 2 bracteoles, linear-lanceolate, 1.5–2.0 mm long. Involucres sub-hemispheric to obconic in shape, 3.5–4.5mm long, 1.0–1.5mm in diameter. Phyllaries 14–25 in 2–3 series, 3.5–4.5 mm long, 0.5–0.6 mm wide, narrow, strigose near base becoming sparsely strigose to glabrate nearing apex, entire to remotely toothed, sharply acute, margins hyaline and ciliate near base. Outermost phyllaries greatly reduced. Ray florets pistillate, 15–25 in 1 series, ray corolla tube 1.7–2.1mm long, ligule 1.3–2.0 mm long, 0.2–0.3 mm wide, apex truncate to rounded, usually white, becoming recurved with age. Disk florets bisexual, 3–6, goblet-shaped, corolla lobe margins thickened, initially fusing with a pronounced suture, fading in prominence on the tube, corolla (1.6–)1.8–2.0mm long, tube 1.0–1.5 mm long, maroon in bud becoming yellow in anthesis.

Fruit: Fruit a simple; dry; achene (cypsela); 1.5–2. mm long; 0.6–0.8 mm wide; oblanceolate; sparsely glandular strigose on both surfaces; becoming more strigose towards apex; edges thickened; coriaceous; 0–1 nerved on faces. Pappus white; 2.3–3.2 mm long; bristles barbellate. Seeds 1 per fruit; erect; embryo straight.
