BERRY: MESOzOIC FLORA OF ATLANTIC COASTAL PLAIN 69 
might be wished, although some of these obviously, as in the 
case of Ternstroemites, represent the stock from which the Ter- 
tiary and existing genera were differentiated, and it is note- 
worthy that sixteen of the genera have not been recognized in 
post Cretaceous deposits. The following are the extinct genera 
of the Ripley flora: Halymenites, Raphaelia, Dryopterites, Mon- 
heimia, Taeniopteris, Protophyllocladus, Widdringtonites, Cunning- 
hamites, Moriconia, Geinitzia, Alismaphyllum, Doryanthites, Dtos- 
corites, Geonomites, Dryophyllum, Menispermites, Acaciophyllites, 
Mimosites, Caesalpinites, Gleditsiophyllum, Leguminosites, Eu- 
phorbiophyllum, Manithotites, Cissites, Grewiopsis, Dtllenites, 
Ternstroemites, Laurophyllum, Myrtophyllum, Cornophyllum, Ace- 
rates, Apocynophyllum, Calcites, Carpolithus, Phyllites. 
There follows a systematic list of the plants that have been 
identified from the Ripley formation. These will be fully de- 
scribed and illustrated in a Professional Paper of the U. S. Geologi- 
cal Survey, the manuscript of which has already been submitted, 
but which will probably be several years getting into print.
