1. U. radiata, (Sieb.) so called from the rayed appearance of 

 the flower-buds, is a tree of moderate size, grooving on the banks 

 of the Nepean River and some of the adjacent creeks, and often 

 seen with long strips of bark hanging from the upper branches. 

 It is usually called '' River "White Gum," because the butt and 

 branches are white and smooth, when they have shed their bark. 

 In the Flora Austral iens is, (Vol. III., p. 203), it is described as a 

 Ymeiy oi E. amy gdal ma, (LabilL), or the ''Messmate" of the 

 Southern Ranges, and Baron F. von Mueller, in his Eucalypto- 

 grapliia (Decade 5.) a^ipears to adopt the same view for the 

 purposes of classification. Although the flowers, fruit, and leaves 

 of the trees are very similar, yet they differ most materially in 

 bark, habit, size, and wood. E. amygdalma, as it is seen on the 

 Mittagong Range, belongs to the section HemiphloicB, attains a 

 gigantic size, and affords useful timber ; whereas E. radiata 

 occurs only near rivers, has a smooth bark, never rises very high, 

 and is not esteemed for its wood. No one who has examined the 

 trees in their native soil, would suppose that they could be 

 reduced to the same species ; and although the anthers of both 

 are similar in shape, yet the fruit and the leaves are by no means 

 identical. In the supposed varieties of E. amygdalina, however, 

 the leaves abound in volatile oil, and are opposite and alternate ; 

 and thus, as there are certain points of resemblance amongst 

 them, it is not surprising that a mere inspection of dried specimens, 

 independent of any reference to habit, should lead to the conclusion 

 that E. radiata is only a form of E. amygdalina. 



2. E. saJigna, '' the Blue or Flooded Grum " of N. S. Wales, is 

 one of the finest of our Eucalypts, rising to 100 or 120 feet with
