NOTE ON THE OCCURRENCE OF LEPIDODENDROF 

 IN UPPER DEVONIAN ROCKS AT MOUNT LAMBIE, 

 NEAR RYDAL, NEW SOUTH WALES.

As far as the authors are aware, the occurrence of Lejoidodendron 

 in Australia in rocks, for the Devonian Age of which there is 

 strong evidence, has not hitherto been proved. The object of the 

 present note is to show that the result of recent examinations by 

 the authors of the neighbourhood of Mount Lambie in New South 

 Wales proves that a species of Leindodendron occurs there in 

 rocks probably of Upper Devonian Age. 



The literature on the subject of Lepidodendron australe has 

 been well summarised by Mr. R. Etheridge, jun., in an article 

 contributed to the Records of the Geological Survey of New South 

 Wales. "^ 



According to the above article, William Carruthers published 

 the first description of an Australian Lepidodendron^ under the 

 name of L. 7tothum, Unger. McCoy next described a species of 

 this genus from the Avon River, Gippsland, Victoria, as Lepido- 

 dendron australe. Carruthers' specimens were forwarded by the 

 late R. Daintree from Mount Wyatt, Canoona, and the Broken 

 River, in Queensland, and were considered by him to be of Old 

 Pved Sandstone Age. 



Mr. Etheridge gives the age of the Avon River Sandstones as 

 Lower Carboniferous, but Mr. It. A. F. Murray, in his "Geology 

 and Physical Geography of Victoria,"! classes the Avon Fa\er
