Branched shrub to 4(-5) m tall; twigs minutely whitish to reddish cinereus xvith fine, weak, spreading or crumpled hairs, drying faintly angled. Leaves elliptical to lanceolate, mostly to 10-12 cm long, 3-5 cm broad, apically acute or obtuse, mucronulate, basally acuminate or acute, the margins entire or with a few teeth, ca. 8 veins on each side of the prominent midvein, wider spaced upwards, felty tomentose beneath with weak whitish or greyish hairs, drying lighter beneath; petioles stout, 10-15 mm long, fine-tomentose. Inflorescence a somewhat congested cymose panicle with many florets, held erect above the foliage, with undifferentiated bracts and occasional linear bractlets ca. 5 mm long. Heads campanulate-cyathiform, somewhat flat-topped, disciform; involucral bracts numerous in several unequal series, indurated, dorsally tomentose, ca. 2 mm long, apically rounded to acute, entire, minutely erose or ciliate; ray florets numerous, capillary, 4 mm long, the corolla purplish, apically denticulate, basally expanded around the style base, the style branches slender, the style base globose, ca. 3 times the diameter of the style, elevated from the ovary on a distinct stipe, the ovary fertile, slightly flattened, oblong-cylindrical, basally expanded at the carpopodium and apically expanded at the pappus, the 3-5 ribs pubescent with ascending hairs; disc florets few, 5 mm long, the corolla narrowly tubular, expand- ing upwards, the 5 apical lobes dorsally papillose with whitish trichomes, other- wise glabrous, the anthers 2-3 mm long, the appendages narrowly obtuse, the basal tails filiform, partly connate, the style branches flattened, the style base expanded-globose, the ovary rudimentary, sterile.

Note
|
Godfrey (1962) applied the name Pluchea odorata to this species. Lecto- typification of Conyza odorata correctly reassigns that name to the other Pana- manian species of Pluchea leaving Pluchea carolinense as the correct name for the taxon described above.
