bears a profusion of blossoms which are of a darker yellow colour 

 than those of many Acacias. Its flowering time is about the first of 

 September. 



Eucalyptus coriacea, the Snow-Gum of Kosciusko, was found on 

 alkaline rocks from the 4,600 feet level up to the actual summit of 

 Mount Lindsay or Kaputar, the later being about 5,000 feet above 

 sea-level. This is the Euealypt which climbs above all others in 

 New South Wales, and reaches the greatest altitude of any Euea- 

 lypt in Australia. In various isolated situations, as on some of 

 the narrowest parts of the Liverpool Range, and on the Nandewar 

 Mountams, its occurrence is suggestive of its being a relic or 

 stranded plant. Although it reaches an elevation of 6,500 feet on 

 Mount Kosciusko,* it by no means takes the highest land in Tas- 

 mania, being absent from the summit of Mount Wellington (4,166 

 feet), and also from the summit of Mount Roland at nearly 4,000 

 feet, where it was specially searched for by Mr. E. C. Andrews and 

 myself in February, 1911. On Mount Roland, rather stunted forms 

 of E. Gunnii Hk., and E. cocci fera Hk.,are common, while E. cocei- 

 fera and E. vernicosa Hk., occur on the summit of Mount Welling- 

 ton. 



Taking those plants which are common to the coldest parts only 

 of this State, and to Tasmania, my observations go to show that 

 such plants require an increased minimum altitude of about 1,000 

 feet for every 300-330 miles in their distribution northerly from 

 Tasmania to northern New South Wales. E. coriacea is one of 

 these cold-loving plants, and as the direct distance from Hobart to 

 Moimt Kosciusko is about 450 miles, the presence of this Snow- 

 Gum at 6,500 feet on Kosciusko should imply its occurrence in Tas- 

 mania at levels up to about 5,000 feet, provided the geological for- 

 mation and aspect were suitable. So far as the former is concerned, 

 the rocks of Mount Wellington appear such as would support the 

 growth of this species in New South Wales, while those of Mount 

 Roland may be too acid. This Snow-Gum is also a lover of open 

 country, usually avoiding scrvibby land, and will, in some situa- 

 tions, occupy large areas almost exclusively. It may, therefore, be
