Leaves ascending to spreading, distally recurved; blades narrowly obovate (sometimes conduplicate), 6–12 × 2–4 mm, midnerves raised adaxially, (margins often undulate) apices acute, mucronate to cuspidate, faces gland-dotted to resinous; sometimes with axillary fascicles of 1–7 leaves. Heads usually borne singly, sometimes in cymiform to racemiform arrays (4–6 cm wide). Peduncles 1–15 mm (bracts 0 or 1–4, scalelike). Involucres narrowly campanulate, 8–12 × 4–6 mm. Phyllaries 22–28 in 4–6 series, green to tan, squarrose or reflexed (outer), ovate to oblong, 2.5–7 × 0.6–1.5 mm, unequal, outer herbaceous or herbaceous-cuspidate, innermost chartaceous (bodies usually apically obtuse to retuse proximal to appendages), midnerves and subapical resin ducts darker, apices acute to acuminate, abaxial faces glabrous, resinous. Ray florets 4–7; laminae (white) 4–5.5 × 1–2 mm. Disc florets 10–18; corollas (white) 5.5–7 mm.
