the plant-l)earing strata should he assigned to a Triassic horizon. 

 Through the courtesy of Mr. Draper, I had the opportunity of 

 describing the Vereeniging plants,* which were referred to the 

 following genera : Glossoptcris, Gangamopteris, Nosggerathiopsis, a.nd 

 Sigillaria — types unmistakably indicating a Permo-Carboniferous age. 

 In 1898 Dr. Hatch j gave an account of the Geology of certain dis- 

 tricts in the Southern Transvaal, and in an appendix to his paper I 

 added a short description of a few plant remains from the Vereeniging 

 Sandstone.]: A Geological map of the Vereeniging district is pub- 

 lished in Dr. Hatch's memoir, and sections are also given by Mr. 

 Draper in his paper of 1897. 



The plants from Vereeniging described in the following pages 

 were obtained by Mr. Leslie from the bed of the Vaal Eiver, about 

 3 miles from the locality where Mr. Draper's specimens were 

 collected. An expression of thanks is due to Mr. Leslie for the 

 important additions to the Pakeozoic Flora of South Africa which 

 we owe to his enthusiasm and ability. 



In addition to these Lower Karoo plants from Vereeniging the 

 collection recently submitted to me includes a few very imperfect 

 fragments of leaves from Worcester and Tuin Kraal, a few miles 

 south of Prince Albert Eoad Station, obtained from beds assigned to 

 the Ecca series. The Ecca beds occur mainly in the Karoo, but 

 there is a considerable outcrop also in the Breede River Valley, 

 which has recently been examined by Mr. Schwarz,§ who mentions 

 the occurrence of Gangamopteris impressions in a quarry near 

 Worcester Station. As a matter of convenience the Worcester 

 fossils and those from Vereeniging may be dealt with separately. 



4.— ECCA PLANTS FROM WORCESTER. 



Feistmantel's list of plants from the Ecca series includes the 

 following species : — || 



Glossopteris hroioniana Brongn. 



Gangamopteris cyclop)teroides var. attemiata Feist. 



Nceggerathiopsis kislopi (Bunb.). 



The material in my hands is too meagre and imperfect to lead to 

 any definite conclusion as to the age of the rocks ; it consists of
