THE GLOSSOPTERIS FLORA. 189 



Upper or Stormberg bed. 

 Middle or Beaufort beds. 

 Lower or Ecca and Koonap beds. 



In the Ecca beds boulder deposits occur precisely similar 

 to, and homotaxial with, those of India and Australia. The 

 underlying Table Mountain Sandstones are often marked 

 with deep grooves and exhibit other characteristics of ice- 

 worn rocks. The following plants, among others, are 

 recorded from this horizon : — 



Glossopteris Browniana, Brong. Nceggerathiopsis Hislopi, Bunb. 



Gangamopteris Cyclopteroides, Feist. Etc., etc. 



From the overlying Beaufort beds we have a flora 

 similar to that of the Indian Damudas and Australian New- 

 castle Strata. 



In a collection of plants recently forwarded by Mr. 

 Draper from a locality not far from Johannesberg, there are 

 numerous Glossopteris leaves associated with casts of fairly 

 well-preserved Lepidodendroid or Sigillarian stems. The 

 association of these forms is of special interest, and a more 

 complete examination of the specimens may throw fresh 

 light on some points connected with the distribution of the 

 Glossopteris flora. Professor Zeiller ^ has lately described 

 several species, including Glossopteris, N^oeggeratJnopsis, and 

 others from the neighbourhood of Johannesberg. It is 

 impossible, however, in this summary to do more than 

 mention the facts, but it is hoped to discuss elsewhere the 

 nature of the South African plants in a more complete 

 manner. 



South America. — In 1889 Mr. Derby ^ recorded the 

 occurrence in the Province of Parana of wide-spread boulder 

 beds similar to those of India and elsewhere. His observa- 

 tions, however, were of a superficial character, and in them- 

 selves of little value for purposes of exact correlation. 

 Recently some very important and interesting additions 

 have been made to our knowledge of the geology of this 

 country.^ In 1869 Carruthers* described a number of plants
