228 J. H. MAIDEN. 



prehensively, and there seems but little doubt that what 

 he meant in 1842 as New South Wales referred to Victoria 

 before the separation, and Mitchell's route through Victoria 

 in 1836 would enable the modern botanist to pick up a very 

 close approximation to the type. 



Habitat — The habitat of A. Westoni is the northern and 

 western slopes of Mount Jerrabomberra, near Queanbeyan 

 and within the Federal Territory, vide plan (not reproduced). 

 The altitude is 1950 to 2400 feet above sea level. The area 

 of distribution is approximately 2000 acres. The nature 

 of the soil is sandstone of very fine texture at the higher 

 levels, on the lower levels the soil is of the nature of a 

 clay-loam formed in large measure from an overlying 

 fractured shale. 



Size — Twelve of the largest at three feet from the ground 

 gave an average girth of 24*396 inches. Six of these were 

 above twenty-five inches and six below. Their height is 

 twelve to fifteen feet. A few of the best specimens are 

 fully eighteen feet. The best specimens are invariably 

 found on the lower levels. The great mass of trees are 

 upon die higher portions of the mount. This no doubt is 

 in great measure due to the fact that here the country is 

 unimproved, whereas upon the lower places grazing has 

 been in full swing for many years. 



The other trees observed in the area are Acacia dealbata, 

 A. diffusa (?), A. rubida, A. decurrens var. mollissima. 

 Of the above, A. diffusa (?) is by far the most numerous. 

 The other species are represented by a few specimens 

 only. Also Eucalyptus macrorrhijncha, E. polyanthemos, 

 E. melliodora, E. tereticornis (?), E. Stuartiana and E. 

 maculosa. Of these E. macrorrhyncha is the predomin- 

 ating species. 



A sample of the bark has been analysed with the follow-
