324 BOTANY OF THE INTERIOR OF NEW SOUTH WALES, 



The Acacias noticed between Mount Tinda and Condobolin 

 were: — A. homalophijlla, A. dealhata (green variety), A. Osivaldi, 

 A. decora (chiefly on porphyry), A. doratoxylon, and near the 

 Lachlan at Condobolin A. salicina (Cooba or Native Willow) and 

 A. pendula (Boree or Myall). 



The Eucalypts observed were : — E. popidifolia, E. oleosa, E. 

 damosa (as a Mallee scrub with E. sideroxylon (Ironbark), along 

 the edge of it), E. WooUsiana, E. tereticornis, var. dealhata (with 

 partially-double operculum, near Mount Nobby), E. viridis and E. 

 intertexta. After reaching the Melrose Road at 24 miles from 

 Condobolin, the Eucalypts passed were as follows : — E. populi- 

 folia (all the way), E. intertexta (scarce),^. Woollsiana{?iVi. the way), 

 (21 m.), E. oleosa (8 m.), E. tereticornis, var. dealhata, E. dumosa 

 (7 m.), a few trees of E. intertexta (6 m.), E. oleosa (fairly large), 

 E. sideroxylon (4 m.), one tree of E. intertexta, and E. tereticornis, 

 var. dealhata. 



Finding E. sideroxylon and E. Woollsiana growing together 

 between the 3- and 4-mile posts, I searched for the supposed 

 hybrid or Ironbark Box, and succeeded in finding a few trees on 

 the eastern side of the road. None were growing within sight 

 from the road, and had their presence not been suspected, they 

 would have been passed unnoticed. They were in ever)^ respect simi- 

 lar to those found north of Nymagee and mentioned in a previous 

 paper (Part ii.) These trees can generally be at once detected by 

 their bark, it being rougher than the Box and smoother than the 

 Ironbark, and usually is somewhat of a yellowish-brown colour, 

 especially towards the upper part of the trunk. 



On the Lachlan, close to Condobolin, Eucalyptus rostrata, E. 

 melliodora, and E. largiflore^is were noticed. 



Just above Condobolin are trees of E. largijiorens and E. 

 Woollsiana growing together, and undoubtedly a casual observer 

 would class them as the same species. In this particular case the 

 leaves of both are rather pale, and do not present the usual 

 contrast that is to be noticed between these trees. A little 

 inspection, however, soon yeveals the distinction in the bark on
