Certain bands in the overlying sandstones are rich in fossil 

 plant-remains. Mr. Leslie, the owner of a quarry at Yereeniging, 

 was good enough to make for me a collection of these plant- 

 remains ; the specimens have been submitted to Mr. A. C. Seward, 

 who favours me with the following description of them. 



Notes on the Plant-Remains. 

 By A. C. Seward, Esq., M.A., F.G.S. 



The specimens sent to me from Dr. Hatch are in the form of 

 impressions on a fine-grained sandstone from Yereeniging. They 

 consist of Glossopteris Broivniana, Brongn., Gangamopteris cyclo- 

 pteroides, Feist., Noeggerathiopsis Hislopi (Bunb.), and an imper- 

 fectly preserved Sigillaria, with portions of stems which I am 

 unable to identify from the imperfect fragments. This association 

 of species, which has been recently described from the Yereeniging 

 rocks,^ points to a Permo-Carboniferous age. The large parallel- 

 veined leaves referred to as those of Noeggeratliiopsis Hislopi 

 are much better than any of the specimens sent to me by 

 Mr. Draper from the same locality ; their striking resemblance to 

 European species of Cordaites suggests the possibility that some at 

 least of the Southern Hemisphere leaves referred to Noeggerathiopsis 

 would be more correctly designated Cordaites. E-ecent discoveries 

 have made us acquainted with new points in common between the 

 northern and southern Permo-Carboniferous floras, and it is probable 

 that the genus Cordaites may be another type which existed in the 

 two botanical provinces of Upper Palaeozoic times. 



1. Gangamopteris ctclopteeoides, Feist, (cf. G. cyclopteroides, var. 



attenuata). The midrib is rather apparent than real, the veins 

 radiating from the base of the frond. Probably identical 

 specifically with the species sent by Draper.^ 



2. Portions of two leaves, possibly Glossopteris^ which probably 



formed part of a tuft of long narrow fronds. 



3. Fragment, most likely Glossopteris. 



4. («) Part of a frond of Gangamopteris cyclopteroides. The 



broad ridge in the middle of the leaf is a feature which 

 appears to characterize these South African specimens. Indian 

 examples occasionally show a similar median line, but most 

 of them are without anything suggestive of a midrib.^ 

 (h) Frond of Glossopteris Browniana, var. indica, Brongn.*
