Definition of greenbrier in English:
A green-stemmed North American vine of the lily family, typically prickly and with blue-black berries. Also called catbrier.
- The undergrowth is often dense with dwarf palmettos and with such vines as earleaf, saw greenbriers (both very prickly), muscadine, and summer grape, all tough on hikers.
- Common midstory and understory species included red maple, American beech, greenbrier, and spicebush.
- Because the canopy is relatively open here, the vegetation is often overgrown with rattan vine, greenbrier, wild grape, pepper vine, trumpet creeper, Virginia creeper, and poison ivy.
