330 BOTANY OF THE INTERIOR OF NEW SOUTH WALES, 



occurs to the west and north-west of Dubbo, but is very rare to 

 the east of a line joining Dubbo, Bogan Gate and Temora. Over 

 the Macquarie and Lachlan country it is the most eastern of all 

 the Mallees, and in approaching its habitat its presence is often 

 indicated by the fact that the straight tough stems of these little 

 trees may be seen on the carriers' wagons, where they are used 

 as " twitch sticks " to tighten the ropes which fasten the loads. 



Parkes is slightly over 30 miles south-easterly from Trundle, 

 and between these towns the following trees and shrubs were 

 noticed : — Callitris robusta (practically all the way), Apophyllum 

 anomalum, Casuarina Luehmanni (plentiful), Heterodendron 

 olemfolium, Myoporum deserti^ Hakea leucoptera, Geijera parvijiora, 

 Casuarina C amhagei, Exocarpus aphylla, Dodoncea viscosa, Bertya 

 Cunning hamii, Olearia sp., (22 m. from Parkes), Exocarpus 

 cupressiforniis (21 m.), Leptospermum sp., Grevillea florihunda^ 

 Melichrus urceolatus, Hihbertia sericea, Benth., Eremophila 

 Mitchelli, Cassia sp., Callitris calcarata (18 m.), Eremophila longi- 

 folia{\^xn..), Fusanus acuminatus, Casuarina Luehmanni (11 m.), 

 Sterculia diversifolia (5 m.), Tenipletonia sp. (without flowers), 

 Geijera parvijiora (2 m.), and Eremophila Mitchelli. 



The Acacias noticed along the road were: — A. homalophylla, A. 

 Oswaldi, A. decora, A. hakeoides, A. dealbata (green variety), A. 

 doratoxylon (15 m.), A. spectabilis, A. Cunn., (the first seen; 10 m.), 

 A. pendula (5 m.), A. decora (2 m.), and A. Oswaldi. 



The patch of Myall between the 9- and 10-mile posts north- 

 westerly from Parkes marks its most eastern locality in the Parkes 

 district. Formerly it grew on a plain about half-way between 

 Parkes and Forbes, but there is scarcely a living tree to be found 

 there now. 



At about 15 miles from Parkes, towards Trundle, there are a 

 few trees of an Acacia which appears to be either A. implexa, or 

 A. melanoxylon, but in the absence of both flowers and pods the 

 species was not identified. I have never seen the latter so far 

 west as this, and the former only on two occasions already 

 mentioned. Either species seems out of place in the far west.
