INTRODUCTION. 
The fossil plants described in the following pages represent collections from 
two localities, viz. — Cockabutta Mountain, and Talbragar. From the 
former only a few specimens are available, poorly preserved in a fine-grained 
ferruginous shale; from the latter, on the other hand, specimens are very 
numerous, and are well preserved as white siliceous impressions on an ochreous 
coloured shale. This method of fossilisafcion unfortunately does not lend 
itself to the preservation of internal structure. Associated with the plants 
at Talbragar are very numerous fish remains which have been described by 
A. S. Woodward, 1 and also a single insect ( Cicada ? Lowei) described by 11. 
Etheridge, junior, and A. S. Olliff. 2 
1 desire to express my indebtedness to Mr. W. S. Dun, Palaeontologist 
to the Geological Survey, through whose generosity I have been able to 
examine and describe these collections of plants. 1 have also to thank Mr. J. 
. 
Mitchell for allowing me to examine his collection of fossil plants from 
Talbragar.
