Plants 30–50 cm. Stems erect to spreading, green when young, fastigiately branched, glabrous or sparsely hairy, resinous. Leaves mostly ascending to spreading, often recurved distally; blades filiform to narrowly oblanceolate (adaxially sulcate), 10–25 × 0.5–1.5 mm, midnerves obscure, apices apiculate, faces glabrous, resinous (axillary fascicles usually present). Heads in loose, cymiform arrays (1–4 cm wide). Peduncles 1–10 mm (bracts 0–15+). Involucres obconic, 5.5–8 × 3–5 mm. Phyllaries 22–34 in 4–5 series, green to tan, lanceolate to oblong, 1–6 × 0.5–1.5 mm, strongly unequal (sometimes outer subequal), mostly chartaceous, outer herbaceous or apically so (mid bodies often apically obtuse to notched, with subulate appendages), midnerves evident, (margins narrowly membranous, entire or serrulate, often ciliolate) apices acute to attenuate (outer often squarrose), abaxial faces glabrous, resinous. Ray florets 3–7; laminae (white) 5.5–7 × 1.5–2 mm. Disc florets 10–15; corollas (white) 6–8 mm.
