CARBONIFEROUS AND PERMO-CARBONIFEROUS ROCKS, N.S.W. 283- 



It is, of course, obvious that conclusions based on such 

 an examination must be tentative, pending the results of 

 a complete revision and redescription of the whole flora. 

 When the results of such a revision are available it should 

 be possible to give a much more detailed correlation of the 

 strata ; for the present, however, it seems possible to 

 indicate the age of the beds in a general way with a fair 

 degree of accuracy. 



The plant remains from the Carboniferous strata repre- 

 sent two distinct floras, and there is very little in common 

 between the two. The older flora, occurring in the Burindi 

 Series, is characterised by the preponderance of Lepido- 

 dendron, the newer, occurring in the Kuttung Series, by 

 the abundance of Aneimites and Rhacopteris. There is no 

 doubt that there is a certain amount of intermingling of 

 members of the two floras. Lepidodendron certainly per- 

 sists into the Kuttung Series, for the late John Mackenzie 

 repeatedly recorded the occurrence of Lepidodendron and 

 Otopteris [= Aneimites] together, 1 and there is a specimen 

 in the University of Sydney Collection (No. 991) collected 

 by him, on which Aneimites* ovata and a Lepidodendroid 

 stem occur together. This came from Sawyer's Point, 

 Port Stephens, the horizon being about 2,000 feet below 

 the top of the Kuttung Series, Stems which have been 

 referred to Cyclostigma also occur in the Kuttung Series 

 (Sugar Loaf Creek, Stroud), and it is to be hoped that 

 careful examination of these may indicate more exactly 

 their botanical affinities. 



The flora of the Burindi Series, — The number of species 

 at present known from this Series is small, but many of 

 the specimens are exceptionally well preserved. They 

 include —
