438 NOTES ON NATIVE FLORA OF NEW SOUTH WALES, V., 



stone formation, which accounts for its absence from the Sydney 

 district. 



In the forest E. quadrangulata much resembles E. Rudderi 

 Maiden, of the North Coast, partly from its growing in corres- 

 ponding situations, and also because the tall straight boles and 

 branches of each are covered with similar grey box-bark; but the 

 juvenile foliage and timber afford a ready means of distinction 

 to the field botanist. 



E. piperita and E. amygdalina are associated on the sandstone 

 and syenite, but the former was not found on the shale; and 

 although it continues from Bowral right down to Port Jackson, 

 it does so by following the sandstone areas, avoiding the Wiana- 

 matta Shale. E. piperita is one of those plants which by its 

 presence almost invariably announces the fact that the rock in 

 the vicinity is sandstone, its occurrence on the syenite being an 

 exception. Owing to climatic influence E. amygdalina does not 

 follow far towards Sydney, it being a distinctly cold country 

 species, and thrives at elevations above that at which E. jriperita 

 usually grows. 



E. viminalis is common on the basaltic hills around Bowral, 

 which is a characteristic feature in the various States where it 

 grows, but it is not confined to igneous formation, though it is 

 somewhat rare on sandstone. 



E. coriacea, the Snow Gum of Kiandra and Kosciusko, in its 

 passage from Tasmania to New England, reaches Bowral on the 

 eastern margin of its habitat; and north of Goulburn is seldom 

 found below an altitude of 2000 feet, while it grows at elevations 

 exceeding that of all other Eucalypts. 



In order to localise the plants, the following lists are so divided 

 that the first refers to the conspicuous members of the flora, 

 other than Eucalypts, on the sedimentary formation which 

 extends about half-way, viz., 22 miles. The second list mentions 

 the plants observed during a walk across the syenite hill, locally 

 known as The Gib, and is given for the purpose of comparison. 

 The third list comprises the flora noticed on the second part of
