Alluvial streamside vegetation. North of Limestone 

 the bottomlands are largely neglected and uncultivated 

 and along the banks of the "Tuna" creek, its branch 

 streams, the bayous and depressions caused by former 

 stream channels are to be found dense thickets of very 

 rank herbaceous and woody vegetation. Some of them 

 are almost impenetrable owing to the density, the size of 

 the herbaceous vegetation and the interlacing growth of 

 various vines. This association of plants is an excellent 

 example of what our native vegetation can do if given a 

 good opportunity. 



The tree growth is naturally limited. These consist 

 chiefly of Black Willow, Salix nigra (and the smaller 

 Salix cordata and Salix sericea) ; Silver Maple, Acer 

 saccharinum; and scattered trees of Elm, Ulnius ameri- 

 cana; Sycamore, Plat anus occidentalis; Box Elder, Acer 

 Negundo, and Red Maple, Acer rubrum. 



The shrubs are mainly the small willows, with Red-osier, 

 Cornus stolonifera; Alder, Alnus incana; Hazel, Corylus 

 americana, and some C. cornuta; Silky Dogwood, Cornus 

 Amornum; Wild Black Currant, Ribes americanum ; Pan- 

 icled Dogwood, Cornus candidissima; Nannyberry, 

 Viburnum Lentago ; Elderberry, Sambucus canadensis, 

 and Arrowwood, Viburnum dentatum. Occasionally the 

 Blackberry, Rubus allegheniensis and the Raspberry, 

 Rubus strigosus add to the impenetrability of the growth. 



Among the vines, both woody and herbaceous, which 

 serve to bind the arborescent and herbaceous vegetation 

 into jungle like growths are : 



Vitis aestivalis Convolvulus Sepium 



Smilax hispida Rhus Toxicodendron 



Clematis virginiana Solanum Dulcamara 



Humulus Lupulus Amphicarpa monoica 



Apios tuberosa Smilax herbacea 



Vitis vulpina Dioscorea villosa 

 Psedera quinquefolia
