182 JURASSIC PLANTS FROM BEXHILL, N.S.W., 



Mitchell's collection contains the following eight species which 

 are described below: — 



Cladophlebis australis (Morris). 



Coniopteris hymenophylloides, var. australica Seward. 



Microphyllopteris pectinata (Hector). 



( 'ycadites sp. 



Tosniopteris spatulata McClelland. 



Araucarites cutchensis Feistmantel. 



Am urn rites (Podozamites) gracilis Arber sp. 



Araucarites {Podozamites) sp. 

 Although none of these species is new, some are new records 

 for Australia, and they afford further evidence of a Jurassic age 

 for the rocks in which they occur. Coniopteris hymenophylloides 

 is a very widespread species in Jurassic strata: Microphyllopteris 

 pectinata occurs in Jurassic and Cretaceous strata in New Zea- 

 land; species of Cycadites range from Rhaetic to Cretaceous: 

 Tceniopteris spatulata has not yet been found in rocks older than 

 Jurassic in Australia, but has been recorded in rocks classed as 

 Rhaetic in New Zealand ; Araucarites cutchensis occurs in 

 (])Rhsetic and Lower Jurassic rocks in New Zealand and Jurassic 

 rocks in India; Araucarites [Podozamites) gracilis occurs in the 

 Jurassic in New Zealand. Thus it will be seen that there is 

 abundant indication that the present collection as a whole 

 represents a flora of Jurassic age.
