plants which become abundant again in the Emscherian. The Dakota 

 flora has usually been considered to be of Cenomanian age; most 

 paleozoologists have considered the overlying Benton as of Turo- 

 nian age and the Montana Group is considered as representing a 

 part of the Senonian. The Atlantic Cretaceous floras have been con- 

 sidered Cenomanian and the associaled and overlying faunas have 

 been considered Senonian. In the authors opinion there are no 

 known Cenomanian floras in America unless the Raritan flora and 

 that of the Washita group of the southwest are of that age, and 

 the Raritan floras of the East are for the most part of Turonian 

 age as is also the major part at least of the Dakota flora of the West. 



The Upper Cretaceous flora of Georgia comprises 32 species, 

 of which 27 come from the Eutaw formation and 9 come from the 

 Riple}^ formation, there being four species common to the two hori- 

 zons. The following are described as new: Dryopterites stephensoni, 

 Andvovettia elegaiis, Ficus georgiana, Menisperinües variahilis, Pa- 

 liuriis Kpatoiensis, Zisyphus laiirifolius, Avalia eutawensis. 



This flora indicates physical conditions similar to those indica- 

 ted by the Middendorf flora of South Carolina. 



The middle Eocene Flora of Georgia is contained in the 

 Congaree shale member of the McBean formation and is of late 

 Claiborne age. The following species, all of which are new, are 

 described: Acrostichuni georgianiiin , Aritndo pseitdogoepperii, Castanea 

 claihornensis, Conocarptis eoceuicn, Dodonaea viscosoides, Ficiis clai- 

 bornetisis, Malapoenna sp., Momisia americaiia, Mivnosites georgianiis, 

 Pisonia claibornensis, Pistia claihornensis, Potaniogeton megaphyUus, 

 Rhisophora eocenica, Sapindiis geovgiann, Sphaerites claibornensis, 

 Terminalia phaecarpoides Thrinax eocenica. 



This flora is not extensive and it embraces a single or at most 

 but two plant associations: one the Strand flora, confined to the 

 beach and the other the coastal swamp flora. The seventeen species 

 are distributed in 15 families and include one fungus, one fern, and 

 four Monocotyledo)iae: a reed, a Potamogeton , a Pistia and a palm. 

 There are 11 Dicotyledonae, representing the families Ulmaceae, 

 F'agaceae, Moraceae, Nyctaginaceae , Mimosaceae, Laiiraceae, Ternii- 

 naliaceae, RliisopJioraceae, Dodonaeaceae, and Sapindaceae. No gym- 

 nosperms which are usually represented in european Lutetian floras, 

 at least by the genus Podocarpus, have been discovered. The plants 

 ndicate a climate that was at least sub-tropical if not more torrid 

 and they show that there was a northward extension of the flora of 

 equatorial America along the Claiborne coast to and probably 

 beyond the latitude of Georgia. Berry.

 Portion ofthe South Wales Coalfield. (Quart. Journ. Geol.

Fifty-three species of plants are recorded from the Pembro- 

 keshire coalfield, including three new species: Anmdaria ingens, 

 Linopteris major and Lepidophyllmn niimis. A new species of the 

 problematical genus Vetacapsula, V. minima, is also described. 



Linopteris brongniarti, Gutb. is recorded for the first time from 

 Britain. Conclusions of importance to stratigraphical geologists are 

 drawn from the palaeobotanical evidence. W. N. Edwards.
