Triosteum perfoliatum R. W. Smith

In forests of beech and maple, oak and hickory, or pine; also in marshy ground and grassy areas.

Fully developed plants with strikingly broad connate-perfoliate leaves at the middle of the stem are easily recognized, but fragmentary specimens can be troublesome. See comments under T. aurantiacum. Triosteum perfoliatum blooms later than T. aurantiacum.
