The Vitis association is very pronounced in such moist forests and along 
river banks. Dense and dark entanglements through which it is difficult 
to penetrate are formed by Vitis cordifolia Michx., V. riparia Michx., V. 
cinerea Engelm., Ampelopsis quinquefolia Michx., and A. cordata Michx.; 
to this list may be added Menispermum canadense L., Cocculus carolinus 
(L.) DC, Celastriis scandens L., Rhus Toxicodendron L., Tecoma radicans 
(L.) Juss., Bignonia capreolata L., Aristolochia macrophylla Lam., Lonicera 
dioica L., Wisteria macrostachya Nutt., and Clematis virginiana L. Some 
of these reach the summits of the high trees, and attract much attention 
during the flowering period. Herbaceous climbers are here represented by 
Smilax herbacea L., S. rotundifolia L., S. Bona-nox L., Dioscorea villosa L., 
Passiflora incarnata L., and Sicyos angulatus L. 
Where forest trees make up a dense formation there are but few species 
of shrubs; but along the edges of these woods and where trees are more 
scattered there are several species of shrubs and small trees, the principal 
ones which are found being Carpinus caroliniana Walt., Ostrya virginiana
