564 THE EUCALYPTS OF PAKIIAMATTA, 



raraatta, I have failed to find it here. As it grows on the 

 Hawkesbury sandstone around Sydney, and at Cronulla and 

 National Park, he may have found it on some of the sandstone- 

 formations herealjout, or he may have classified some of the 

 larger-fruited forms of K. euyetiioides as B. capiteUata. Leaving 

 Fairfield, and working in a north-westerly direction to Prospect, 

 Blacktown, and Seven Hills, the three commonest Eucalypts are 

 still E. hemiphloia, E. tereticornis, and E. crebra, with a propor- 

 tion of E. euyenioides, E. lonyi/olia, and E. siderophloia. At 

 Blacktown, I found a tree of E. Bosistoana(R\hhon or Bastard 

 Box) growing alongside a creek. 



Coming now to the northern side of the Parramatta River, the 

 home of the citrus fruit-growing industry of Australia, one 

 cannot fail to be struck with the immediate change in the 

 varieties of Eucalypts growing there. Instead of the deep clay 

 of the southern part, we have outcrops of Hawkesbury sandstone, 

 and, even where the clay exists, it is mostly a thin layer, through 

 which the roots penetrate to the sandstone. Around Rydal- 

 mere and Dundas, where the sandstone is bare, we find mostly 

 E. resinifera, E. corymbosa (Bloodwood), and E. hcemastoma. 

 E. pilularis (Blackbutt) also grows to magnificent propor- 

 tions, except on the tops of the ridges. Where the sandstone 

 is overlaid by the clay-shale, we find the following species: — 

 E. pilularis, E. punctata (Grey Gum), E. acn/enioides (White 

 Mahogany), E. resinifera, E. paiiiculata (White Ironbark), 

 and E . mli(/na (Sydney Blue Gum). Throughou!: Ermington, 

 Dundas, Eastwood, Pennant Hills, Carlingford, and Dural, 

 these are the prevailing trees. Where the clay is a little 

 deeper, E. eugenioides and E. siderophloia appear; and 

 where it is deeper still, as along the Carlingford Road, E. 

 tereticornis also is in evidence, but without its usual com- 

 panion, E. hetniphloia. At North Rocks, on the sandstone 

 ridge, the Sydney Peppermint, E. piperita, is frequent, while 

 along the creek near the Rydalmere Asylum dairy, a clump 

 of E . robiisfd (Swamp Mahogany) is growing. At Eastwood, 

 Mr. Baker has recorded E. umbra (Bastard White Mahog-
