NATIVE FLORA OF TROPICAL QUEENSLAND. 405 



Eucalyptus rostrata (River Red Gum) is a common tree 

 on the banks of many of the rivers and large creeks of 

 North Queensland. It is often associated with Casuarlna 

 Cunninghamiana (River Oak), and while usually not able 

 to ascend so far, can descend much further down the 

 streams, and this attribute or quality has enabled it to 

 cross the continent from north to south and from east to 

 west. It does not occur in Tasmania and avoids the cold 

 portions of the mainland. 



The tree identified as Eucalyptus clavlgera (No. 4159) is 

 what eastern New South Wales bushmen would be likely 

 to call Apple-gum. Its leaves as seen around Alma-den 

 are sessile, often cordate and opposite, both in the primary 

 and adult forms, and ovate, the hispid midrib and lateral 

 veins standing out in relief on both sides of the leaf, which 

 is excessively scabrous or harsh to the touch. In general 

 appearance the leaves closely resemble those of Angophora 

 subvelutina P.v.M., (Apple Tree) and some of the juvenile 

 forms measured 8 by 5 inches, and it is known that these 

 dimensions are exceeded in other localities. The bark on 

 the main portion of the trunk and branches is white and 

 smooth, while that at the base and for a height of 8 or 10 

 feet, is tessellated in a manner very similar to that of 

 Eucalyptus tesselaris F.v.M., the Moreton Bay Ash of 

 Queensland, or Oarbeen of north-western New South Wales. 

 (Plate LVII, fig. 1). The trees reach a height of fifty feet 

 with a diameter of two to three feet, and if dead, will burn 

 right away after being lighted, a character common also 

 among the Angophoras. Neither buds nor flowers were 

 seen, but some empty seed vessels 1*2 cm. long and 9 mm. in 

 diameter were procured having pedicels up to 2*2 cm. long. 



There seems no doubt that these trees belong to the same 

 species as those referred to by Leichhardt as Apple-gum, 

 and which were first seen by him near the head of the Lynd
