NOTES ON ACACIA. 513 



Allowing for some variation in plants separated from 

 each other by the width of a continent, I think that the 

 resemblance of A. glutinosa F.v.M. to A. ixiophylla Benth., 

 is remarkably close, and concur in Bentham's proposal to 

 combine them. 



The range of A. ixiophijlla, as we know it, affords a 

 remarkable instance of geographical distribution. The 

 species is a denizen of moderately dry localities, and we 

 have it from central Queensland south to the Rylstone 

 district in New South Wales. Then we have a gap until 

 Western Australia is reached and I would invite the atten- 

 tion of botanists to the matter. It (and indeed A. montana, 

 when not in fruit) are species which can readily be passed 

 over for allied species. 



I have a specimen from the Mallee, Wimmera River, 

 Victoria, O. Walter, 10th March 1887, which that gentle- 

 man sent to me as A. montana. It is in pod, without seeds. 

 I have little doubt that it is one of the localities destined 

 to bridge the present A. ixiophylla gap.
