 so extreme a case of departure from the normal type of venation 

 as that of the narrow leaves represented in our figures : it 

 demonstrates the danger of placing too much trust in venation- 

 characters in the identification of isolated specimens. 



Glossopteeis ANGUSTIFOLIA, Bronguiart. 



This species has been previously recorded from Yereeniging under 

 the name of Gl. Browniana^ var. angustifolia. As the impressions

 we think the two kinds of leaf belonged to diff'erent plants, the 

 precise form of the venation does not affect the question of the 

 occurrence of Brongniart's species in the "Vaal beds.

Large leaves of this species have been previously recorded from
