NOTES ON THE BOTANY OF THE INTERIOR OF 

 NEW SOUTH WALES. 



By R. H. Cambage, L.S. 



(Plates xxxix-xl., fig. 3.) 



Part L— From the Darling River at Bourke to Cobar. 



In following my duties as a Mining Surveyor in the Western 

 District, opportunities have been afforded of observing the flora 

 in certain parts of the interior of New South Wales, and though 

 I do not claim to have made a complete botanical survey, but 

 have only noted the principal trees in passing along, I have 

 thought that the information thus acquired might be acceptable. 

 My endeavour has been to prepare it in such a way as to be useful 

 to a student in the field passing over the same country, and to 

 serve as a record for future reference. 



I am indebted to Mr. J. H. Maiden, F.L.S., Director of the 

 Botanic Gardens, and Mr. R. T. Baker, F.L.S., Curator of the 

 Technological Museum, for assistance in identifying some of the 

 plants. 



The country dealt with in Part I. of this paper extends from 

 Bourke to Cobar, but I propose to subsequently speak of the 

 principal trees met with thence to the Bogan, Lachlan, and 

 Murrumbidgee Rivers. 



Starting at Bourke on the Darling River we have Eucalyptus 

 rostrata, Schl., (River Red Gum), following the banks of the 

 stream, where is also Nicotiana ylauca, a tobacco plant introduced 

 from South America. On the level river country a conspicuous 

 tree is Eucalyptus microtheca, F.v.M., (Coolabah), which is easily 

 identified by its rough grey bark all over the trunk, and its
