Morphology

Herbaceous, densely puberulent to nearly glabrous perennial from a stout taproot, to 1.3 m. Leaves subopposite to alternate or sometimes opposite, narrow, dotted with glands beneath, entire to toothed, sessile (some lower leaves petiolate). Heads discoid, terminal, in small corymbiform clusters; involucral bracts imbricate in several series; inner involucral bracts mostly linear or oblong, the outer deltoid to lanceolate, tapering to a point; flowers creamy-white, perfect; pappus bristles all similar, 20; receptacle naked.

Notes

Flowers early August to early October

Wetland indicator: Upland

In the tribe Eupatorieae, which includes plants with style branches cylindric to clavate, obtuse, minutely pappilate, with inconspicuous stigmatic lines near the base (eupatorieous style). Easily mistaken for several species in the genus Eupatorium except for the alternate leaves.

This plant is especially attractive when it goes to seed, at least the ones I have seen, becoming a fleecy silvery-white. This specimen is from a botany class some times ago and I am not positive that it is Kuhnia eupatoroides even though it is named as such given that the leaves appear opposite.
