As regards Victoria, Mueller records it for every district into which he 
botanically divided this State. 
The following botanico-geological note is of considerable interest: — 
A few trees of Acacia impfexa, Benth. (Hickory), were found on the top of the igneous hill (just north 
of Nymagee). This is the most north-westerly locality in which I have found this species. It was next 
seen at a point about 80 miles south-easterly from Nymagee, towards Trundle, and here again it was on 
the top of a hill composed of igneous rock, a very line granite, there being not more than half-a-dozen 
trees. The question'suggested by the position of these isolated representatives of a species which is known 
to extend southerly through New South Wales and Victoria, is whether these trees have once been more 
plentiful in the north-west, and have been reduced by geological and climatic agencies, or whether they are 
only now finding their way out in that direction. Judging from the surroundings I incline to the former 
suggestion, but the solution of the question seems full of interest to both botanists and geologists. (R. H.
