On some Fossil Plants from Dubbo, New South Wales. 



Plate IX. 



By the Rev. J. Milne Curran, F.G.S. 



While attempting to determine the geological position of the 

 so-called Hawkesbary Sandstone at Dubbo, I have been gradually 

 led to study the fossil plants which are so abundantly represented 

 in the district. A few yeai's ago I submitted my collection of 

 fossils to the Rev. J. E. Tenison- Woods, who identified the species 

 already known at that time. Shortly afterwards he gave a diagnosis 

 and figures of all the new species in a paper entitled, " The Fossil 

 Flora of the Coal Deposits of Australia," published in Vol. VIII. 

 of our Proceedings. The following is a list of the fossil plants 

 described therein : 



Filices. 



Sphenopteris crebra, Ten. -Woods. Ballimoi'e. 

 Sphenopteris glossophylla- Ten. -Woods. Baltimore. 

 Neuropteris australis, Ten.-Woods. Baltimore. 

 Thinnfeldia odontopteroides, Morris. Dubbo. 

 Thinnfeldia media, Ten.-Woods. Dubbo. 

 Alethopteris Currani, Ten.-Woods. Ballimore. 

 Alethopteris concinna, Ten.-Woods. Ballimore. 

 Merianopteris major, Feistm. Ballimore. 



Conifers. 



Walchia milneana, Ten. -Woods. Ballimore. 



Since the publication of the paper referred to, I have collected 

 fossils from many parts of the district. Cf these some are well- 

 known species, but others cannot be referred to any hitherto 

 described Australian forms. 



Odontopteris macrophylla, sp. now Plate IX., fig. 3. 

 Frond pinnate and bipinnate. Pinnules more or less opposite, 

 oblkpiely ovate to ovate-acuminate, free, obliquely inserted by
