7. On the Genera and Distribution of Plants in the Carboniferous 
System of New Sout Wates. By the Rev. W. B. Cuarke, 
M.A., F.G.S. 
In Count Strzelecki’s work on New South Wales, it is stated that 
the Australian coal-fields are entirely deficient in the genera Szgilla- 
ria, Lepidodendron, Calamites, and Conifere. This view Mr. Clarke 
considers as erroneous, and endeavours in this paper to remove. 
After some general remarks on the supposed similarity of the plants 
found in the Australian coal beds to those m India, he gives the fol- 
lowing list :— 
Genera of Coal Plants found by Mr. Clarke in the carboniferous 
deposits of New South Wales. 
1. Pecopteris. | 12. Phyllotheca. 
2. Neuropteris. | 13. Zeugophyllites. 
3. Odontopteris. | 14. Equisetum. 
4. Cyclopteris. | 15. Lycopodites. 
5. Sphenopteris. | 16. New genus of plants with wedge- 
6. Glossopteris. / formed stems. 
7. Genus intermediate between Teni- | 17. Lepidodendron, sometimes Lepi- 
opteris and Glossopteris. / dostrobi. 
8. Halonia. / 18. Ulodendron. 
9. Canneform plants. | 19. Sigillaria and Stigmaria. 
10. Reed-like stems. | 20. Coniferze. 
11. Calamites. | 
In all about sixty species. 
On the above list it may be useful to make a few observations. 
The existence of coniferous wood in the Australian coal beds has 
long been known. The Rey. C. P. N. Wilton of Newcastle (N.S. W.) 
sent specimens to Professor Jameson in the year 1832, and on these 
Mr. Nicol reported mm the Edinburgh Philosophical Journal. I have 
also forwarded two specimens of trees, now in the museum of the 
Society, from Awaaba Lake, accompanied by an account of a fossil 
forest of coniferous trees, of which the two in question were exam- 
ples, which was published in the Proceedings*. 
Dr. Leichhardt, in his recent expedition to Port Essington, found 
masses of fossil coniferous wood in a soil, and under circumstances, 
similar to those which distinguish the occurrence of much of the 
fossil Coniferze of the colony, in 23° 8. lat. on the Mackenzie River, 
more than 600 miles northward from Newcastle, and in the vicinity 
of beds of coal undistinguishable from those of the Hunter at New- 
castle, affording evidence of the existence of coal deposits along the 
flanks of the Cordillera of Australia and Tasmania, through a di- 
stance, in latitude, of not less than 1200 miles. 
In the part of the country now under review, coniferous plants are 
not only found za situ imbedded horizontally or standing vertically 
in the various deposits, but are also found lymg upon the surface in 
the shape of local drift; whole trees, some of them 50 or 100, or 
even 150 feet in length, completely changed into silex or hydrated 
iron, existing in this state uninjured, or broken up into clean sections,
