along the crest of ridges Ouercus obtusiloba, but on the lower hillsides and 
steep north slopes is found Ziriodendron, Ouercus rubra, Carya alba (= Hicoria 
ovata), and Fraxinus americana also occurs. The forest of the loose gray 
loams is composed of Ouercus alba, O. falcata, O. obtusiloba, O. tinctoria, Ca- 
rya tomentosa (= Hicoria alba) and Quercus coccinea in abundance in the order 
named, and forming over three-fourths of the growth. As undergrowth we 
find Cornus florida, sour wood Orydendrum arboreum and species of Cratae- 
gus”), Rhamnus and Viburnum. 
Lying to the west of the compact red E gray loams are finegrained and 
mostly sandy loams, usually red or reddish in color with a thin surface soil 
extending to the base of the Blue Ridge and its outlying spurs, constituting 
the western pine land. The trees of the forest on these soils stand in relative 
abundance about in the following order: Pinus mitis, Quercus coccinea, O. 
tinctoria, Q. alba, Oxydendrum arboreum, O. Prinus, O. obtusiloba, O. falcata 
and Carya tomentosa (= Hicoria alba). These trees form considerably over 
three-fourths of the growth. Less abundant and forming the larger portion of 
the remainder of the growth are Cornus florida, Carya porcina (= Hicoria 
glabra), Castanca americana, Quercus marylandica, Pinus inops, Nyssa sylvatica, 
Acer rubrum and Corylus rostrata, Hamamelis. 
Nothing has been published and the writer has no observations of his own 
to offer on the herbaceous plant associations of the Piedmont Plateau 
in North Carolina, but the flora of this region is quite similar in general 
character to. that of the whole district lying at the same elevation from New 
England to Alabama. A comparison of the flora of middle Georgia with that 
of Southern New England shows that at least half of the species of each re- 
gion are common to both. A brief consideration of the plant formations of 
middle Georgia is here represented ?). 
Of greatest interest perhaps are those species which inhabit the rich shady primeval forests 
on the north sides of the hills: Botrychium virginianum, Adiantum pedatum TE ge 
Polystichum acrostichoides, Poa brevifolia, Carex laxiflora, Tradescantia montana, Uvularia per 
foliata, U. puberula, ilacina racemosa, Polygonatum biflorum, Medeola virginica, Dioscorea 
villosa, Silene sellain, Cimieifuga racemosa, Xanthorrhiza apiifolia, Hepatian, Anemone thalictroides, 
Sanguinaria, Dentaria laciniata, Heuchera americana, Geranium maculatum, Viola palmata, V. hastata, 
Aralia (Panax) quinquefolia, Pedicularis canadensis, Mitchella repens, Solidago caesia. 
In drier more open woods, including those on the south sides of hills and the second growth 
oak woods which are frequent on the broad summits of the rid es, the forest consists of Juglans 
nigra, Caryas, Quercus, 6 spec., Prunus serotina and Aesculus flava; shrubs or trees beneath the 
dominant ones: Castanea pumila, Asimina triloba, Cercis, Rhus, Euonymus, Ceanothus, Vaccinium
