Motices of Memoirs — Prof. Seward — Fossil Floras, 8. Africa. 515 



A revision of these records has been recently undertaken with 

 a view to determining the true position of the Ardwiok Series in 

 the Coal-measures as indicated by the character of the flora. For 

 this purpose Binney's collection, now in the Sedgwick Museum, 

 "Cambridge, has been re-examined, and several further identifications 

 have been made. The flora is found to belong to a palaeobotanical 

 horizon known as tlie Upper Transition Series, which is antecedent 

 to the true Upper Coal-measures, and which is represented in several 

 English and Welsh Coalfields. The Lower Pennant Grits in the 

 South Wales and the New Rock and Vobster Series in the Somerset- 

 shire Coalfields belong to this horizon.

1. Uitenhage Flora. — The plants from the Uitenhage series of 

 Cape Colony include types characteristic of Wealden and others 

 more closely allied to Jurassic species. On the whole there is 

 a balance of evidence in favour of a Wealden horizon.

2. Stormherg Flora. — The plants from the Stormberg series point 

 to a flora of Ehgetic age. The RhEetic vegetation, of which remnants 

 have been recorded from Scania, Franconia, and other parts of 

 Germany, North America, New Mexico, Honduras, Tonkin, China, 

 Turkestan, India, Australia, South America, and elsewhere, was 

 characterised by its uniform character throughout the world.

3. Permo-Carhoniferous Flora of Vereeniging. — The conclusion to 

 be drawn from the Vereeniging plants is that they belong to a flora 

 which flourished in South Africa, India, South America, and 

 Australia during some portion of the Permo-Carboniferous epoch. 

 On the whole, it would seem probable that the age of the plant-beds 

 corresponds most nearly with the Upper Carboniferous period as 

 represented in Europe. It is of necessity difficult to attempt to
