smooth bark on the trunk. The trunk and large branches of E. 

 amygdalina are covered with grey fibrous bark. The two species 

 could be easily separated in the forest between Bowral and Wom- 

 beyan during September, by the absence of flowers on E. amyg- 

 dalina and the profusion of blossoms on E. numerosa. In the 

 Bowral district the geological formation renders great assistance 

 in identifying these two species, for while the former is common on 

 the basalt hill from Mt. Oxley northward, it is absent from the 

 syenite and the sedimentary formations, though this does not 

 apply to all districts, and it occurs on the sandstone between the 

 20- and 21-mile posts on the Caves road. On the other hand, E. 

 amygdalina is common on the syenite, the sandstone and the 

 shale, but does not occur on the basalt. 



E. stellulata is growing just to the south of Bowral on the road 

 to Moss Vale. 



The two stringybarks which are found on the sedimentary area 

 along the Caves road are E. eugenioides Sieb. v and E. capitellata 

 Sm., the former being on both the Hawkesbury Sandstone and 

 the Wianamatta Shale, while the latter shows a distinct par- 

 tiality for the sandstone, particularly in the Sydney district. 

 Neither species, however, is restricted to any particular forma- 

 tion 



E. qnadrangulata, the Brush Box of the South Coast, is repre- 

 sented by a few trees about 5 miles out, the country generally 

 being too high and exposed for the species. The long straight 

 stems of these box-trees may be seen towering above the brush 

 or jungle at various places in Illawarra, viz.: — Bulli Pass, Mount 

 Kembla, Barrengarry Mountain near Kangaroo Valley, and 

 also on the igneous formation around Milton. After coming up 

 from the south to Bulli, where it is about a mile from the ocean, 

 it recedes from the coast and continues past Hill Top, from which 

 place it was described, to The Oaks and westward to Burragorang 

 where it is growing on porphyritic formation. The most western 

 locality known for the species is around Yerranderie uear The 

 Peaks, while its northern limit is considered to be the Upper 

 Hunter. It seems to practically avoid the Hawkesbury Sand-
