Triosteum aurantiacum is a tall herbaceous perennial with
opposite, entire leaves sessile or broadly winged at the base
(i.e. there is no clear petiole). The fruit is a drupe, containing
3 nutlets held so tightly together that they may appear to comprise
a single unit if not carefully examined. Stem, leaves and fruit
are all somewhat hairy. It is easiest to recognize in the Fall
when the bright orange fruits are conspiduous. In spite of the
common name, it is not a gentian.
