Smilax herbacea L.
Smooth Carrionflower, Carrionflower
Smilacaceae (Catbrier Family)
Synonym(s): Nemexia herbacea
USDA Symbol: smhe
A vine with broad leaves and stalked round clusters of small, green, putrid-smelling flowers in leaf axils.
This attractive vine climbs over other vegetation by means of tendrils. The unpleasant-smelling flowers attract insects, especially carrion flies (hence the common name), which serve as pollinators. There are at least six species of Smilax in the East; all are thorny, green-stemmed, often evergreen vines that form tangled thickets. The most common are Greenbrier (S. rotundifolia), with heart-shaped leaves and stout thorns; Sawbrier (S. glauca), with heart-shaped leaves, a whitish bloom beneath, and weak spines; and Bullbrier (S. bona-nox), a southern and midwestern species with triangular leaves, stout thorns, and 4-sided stems.
