greater paucity of species, but also in the extraordinary abundance 

 of Glossopteris, and in the occurrence of Gangamopteris and other 

 genera in the southern flora. The facts in regard to the existence 

 of Glossopteris in Northern Europe in Permian times are too well 

 known to need recapitulation, nor need we refer to the South 

 American flora, which Prof. Zeiller ^ has shown to include northern 

 as well as southern species. We are concerned primarily with the 

 African Palaeozoic plants south of the Zambesi, and we would call 

 special attention to the fact that the discovery of Lepidodendron at 

 Yereeniging adds another link between the northern and southern 

 floras : in addition to Lepidodendron, we have Sigillaria, a fairly- 

 common plant at Yereeniging; also Botlirodendron\ and, as we think, 

 the genus Cordaites. Puture discoveries may increase the list of 

 northern types, but it is unlikely that the South African was com- 

 parable in wealth of species with the European flora ; it is, however, 

 certain that there was more in common between the two botanical 

 provinces than it has been customary to suppose. The question of 

 the age of the Yereeniging rocks, as indicated by the plants, is 

 briefly discussed in the concluding section of this paper (p. 122). 



II. Description or the Specimens. 



The following are the species so far obtained from the Yereeniging 

 sandstones : those marked with an asterisk are recorded for the 

 first time : — 



Schizoneura sp. 



Glossopteris indica, Schimper. 

 ^Glossopteris angustifolia, Brongniart, 

 var. tcBnio-pteroides, nov. 



Glossopteris angustifolia, Brongniart. 



Glossopteris sp. cf. Gl. retifera, Feist- 

 mantel. 



Gangamopteris cyclopteroides, Feist- 

 mantel. 

 ^ Callipteridium sp. ? 



Neuropteridiiim validum, Feist- 

 mantel. 



Bothrodendron Leslii, Seward. 

 "^ Lepidodendron vereenigingense, sp. 



nov. 

 ^Lepidodendron Fedroo.nuon (Oarru- 



thers). 

 Sigillaria Brardi, Brongniart. 

 Vsygmophyllmn Kidstoni, Seward. 

 Cordaites (Noeggerathiopsis) Hislopi 



(Bunbury). 

 Conites sp. 



Glossopteris angfstifolia, Brongn., var. t^.niopteroides nov. 

 (PI. IX, fig. 2 ; text-figs. 2 & 3, p. 114.) 

 The incomplete leaf shown in PI. IX, fig. 2 (14 centimetres long, 

 1*8 cm. broad at the upper end and 1*1 cm. broad at the lower end, 

 which is probably not far from the base of the lamina) appears to 

 be identical with Glossopteris angustifolia, in the form of the frond 

 and in the curvature of the secondary veins. A distinct midrib 

 occupies the middle of the leaf, and increases in breadth towards 

 the base of the specimen ; numerous veins are given ojff at an 

 acute angle, which are often forked near the point of origin and 

 dichotomously branched near the edge of the lamina and in other 



a J. G. S. ^0, 253.
