Smilax herbacea

Smilax herbacea L.

Smooth carrionflower, Carrionflower

Smilacaceae (Greenbrier Family)

Synonym(s): Nemexia herbacea

USDA Symbol: smhe

USDA Native Status: L48 (N), CAN (N)

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.
