gradual change in many respects produced by ringbarking and 

 clearing, and to the destruction of the plants by cattle, sheep, 

 &c. Sheep are especially fond of the different species of 

 Diuris, and few of these plants have any chance of flowering 

 where these animals graze 



I append a table of the Mudgee species showing their distribution 

 to other colonies and to the County of Cumberland. This is compiled 

 from the lists given in Mr. R. D. Fitzgerald's Australian Orchids 

 Vol. I., Dr. Woolls' Plants indigenous to the neighbourhood of 

 Sydney, Baron Mueller's Census of Australian Plants, Mr. Bailey's 

 Classified Index of Queensland Plants, and Rev. W. Spicer's 

 Handbook of the Plants of Tasmania. This table is not so 

 complete as 1 should like on account of difficulties in the synonymy. 

 For instance Baron Mueller in his Census does not mention 

 Caladenia clavigera, C . dilatata, C. Jiliimentosa, and C. arenaria, 

 as he considers them merely varieties of C. Patersoni, I believe. 



The numbers opposite each genus show how many species of it 

 have been found in the different colonies.
