species. The typical E. hemiphloia, F.v.M., is more of a coast 

 form, and though common on the Wianamatta Shale and igneous 

 formations, it is less plentiful on the Hawkesbury Sandstone, 

 and altogether is not so strongly represented in this State as the 

 variety alhens. 



In coming from Cobar to Parkes I expected at some point to 

 find E. melanophloia, Benth., the Silver- Topped Ironbark, but 

 failed to do so. Its most southern locality, therefore, so far as I 

 know, is around Narromine. Neither was E. siderophloia, F.v.M., 

 seen, but it occurs at a point about 30 miles north of Parkes and 

 8 miles east of Peak Hill, which is probably its most southern 

 locality in the western district. 



The total number of Eucalypts noticed between Mount Hope 

 and Parkes was fifteen, viz. : — E. populifolia, E. intertexta, E. oleosa, 

 E. dumosa, E. viridis, E. tereticornis (scarce), E. tereticornis, var. 

 dealbata, E. WooUsiana, E. rostrata (only on creeks and the 

 Lachlan), E. melliodora, E. conica (only in the eastern part), 

 E. largijlorens (on the Lachlan only), E. sideroxylon, E. hemi- 

 phloia, var. alhens (only close to Parkes), and the Ironbark Box. 



The Acacias were represented by A. homalophylla, A. ijendula 

 (not plentiful), A. decora, A. hakeoides, A. dealbata (green variety), 

 A. colletioides, A. triptera, A. aneura (in the western half only), A. 

 excelsa (scarce), A. Oswaldi, A. doratoxylon, A. Burkittii (in the 

 western half only), A. calamifolia (in the western half only), A. 

 amblygona (scarce), A. conferta, A. iniplexa (scarce), A. salicina 

 (on the Lachlan only), and A. spectahilis (close to Parkes). 



The Casuarinas were: — C. quadrivalvis, C. Luehmanni, and 

 C. Camhagei.
