stipitate- to sessile-glandular (commonly with eglandular but viscid hairs as well), not arachnose.
minutely puberulent and sessile-glandular, usually also closely arachnose (hairs appressed).
petiolate or sessile;
blades (succulent, drying thin) lance-ovate to ovate or ovate-elliptic, mostly 4–15 × 1–7 cm, margins shallowly serrate, faces glabrate to moderately or densely pubescent (hairs crinkly).
petiolate (petioles 10–20 mm);
blades elliptic to oblong-elliptic, 6–15 × 3–7 cm, margins dentate-serrate or entire, faces glandular-puberulent or puberulent and sessile-glandular.
cylindro-campanulate, 5–6 × 4–8(–10) mm.
campanulate, 4–6 × 3–4 mm.
pink to rosy or purple.
rose purplish.
usually cream, sometimes purplish, minutely sessile-glandular (outer usually also puberulent), sometimes glabrate.
usually cream, sometimes purplish, minutely sessile-glandular (the outer also sparsely puberulent), sometimes glabrate.
in corymbiform arrays (flat-topped to rounded, often layered, sometimes incorporating relatively long, leafy, lateral branches, clusters of heads terminal on branches, some lateral branches nearly equaling or surpassing central portions).
in paniculiform arrays (of rounded-convex, corymbiform clusters terminating branches from distal nodes, arrays usually resulting from axillary, strongly ascending, bracteate branches, the central axis longest and first to flower and, rarely, the only component of an array).
persistent, bristles distinct.

Pluchea camphorata is similar to P. odorata and rarely may hybridize with it. In P. camphorata, the phyllaries of the inner 2–3 series are thin and nearly translucent, lanceolate, and more than twice as long as deltate-ovate phyllaries of the outer series. The inner may be glandular but they are otherwise glabrous, prominently different in vestiture from the outer. The phyllaries of P. odorata are more strongly graduated and the inner are glandular and also clearly puberulent as well.
