52 MISSISSIPPI STATE GEOLOGICAL SURVEY [Bull. 
is black, peaty ,and acid. All the streams flowing through this 
region are sluggish and tortuous, with sandy bottoms and clear, 
aimber-colored, peaty water. 
This whole area is clothed with an open growth of pine and 
on the wet acid soils occurs an undergrowth of characteristic 
species resembling that cf northern bogs. From a floristic 
point of view it is perhaps the most interesting region in the 
state, possessing more species peculiar to itself than any other. 
The trees and shrubs cf the dryer areas are represented by 
the following pecies: 
Pinus australis Quercus cinerea 
Pinus taeda Acer dasyecarpum (along 
Pinus heterophylla streams) 
Quercus Virginiana Simplocos tinetoria 
Quercus laurifola Cyrilla racemiflora 
Quereus Catesbaei Cliftonia, ligustrina 
(Quercus nigra Oxydendrum arboreum 
Magnolia grandiflora 
Some of these species are also found along streams and 
bordering swamps. Others found in the low wet depressions 
are: 
Ilex glabra (in dense thickets) Chamaecyparis thyoides 
Ilex vomitoria Cliftonia ligustrina 
Magnolia glauca Cyrilla racemiflora 
Andromeda, nitida Azalea viscosa 
Osmanthus Americana Azalea nudificra 
Gaylussacia dumosa Serenoa serrulata 
Nyssa aquatica Persea pubescens 
Nyssa uniflora 
Herbaceous species of the higher and drier soils are re- 
presented by the following: 
Polygala lutea Hypericum densiflorum 
Polygala nana Viola primulaefolia 
Rhexia glabella Trilisa odoratissima 
Rhexia Virginica Linum Floridanum 
Rhexia stricta Pingeuicula lutea
