Berry: MESOZOIC FLORA OF ATLANTIC COASTAL PLAIN 57 
FLORA OF THE EUTAW FORMATION 
The Eutaw flora is still incompletely known. The Eutaw 
sediments, in so far as they might preserve land plants successfully, 
are either marine clays or littoral, prevailingly sandy, deposits. 
The former contain only decay-resisting forms, such as Araucaria 
twigs and coriaceous dicotyledons, and the latter similar forms 
that successfully withstood the triturating action of troubled 
waters, since as yet no clay lenses with any extensive represen- 
tation of plants that grew along the Eutaw shores have been 
discovered. The Eutaw flora, which has been collected chiefly 
from the Chattahoochee valley in Georgia, from near Havana in 
Hale County, Alabama, and from near Beacon in Decatur County 
and at Coffee Bluff in Tennessee, consists of but forty-six species. 
It includes no ferns, thirty-four angiosperms and eleven gymnos- 
perms. Among the latter are the genera Androvettia, Brachyphyl- 
lum, Cephalotaxospermum, Cupressinoxylon, Sequoia and Tumion, 
which are unknown in the Ripley, as well as the twigs and scales of 
Araucaria which, although recorded from the Ripley, come from 
deposits of the same age as the Eutaw in other regions. These 
are preserved in the Eutaw because of their resistance to macera- 
tion but should be present in the Ripley if they had not become . 
extinct. 
Similarly among the dicotyledons the prevailing forms found 
in the Eutaw are coriaceous types, such as Andromeda, Cinnamo- 
mum, Ficus, Magnolia, Myrcia, Manthotites, Sabalites and the like. 
Following is a list of the known Eutaw species, those marked 
with an asterisk being also present in the Ripley. Sixteen of the 
Eutaw species continue into the Ripley, but the following genera 
of the Eutaw have not been recognized in the Ripley: Androvettia, 
Brachyphyllum, Cephalotaxospermum, Cupressinoxylon, Dewalquea, 
Diospyros, Paliurus, Pterospermites, Sequoia and Tumion.
