smaller, and it' these trees are hybrids between E. sideroxylon and 

 E. WooUsiana, the difference in size of fruits would be accounted 

 for, as those of the latter are generally less than half the size of 

 E. heniipMoia var. nlbens. 



If E. ajflnis were originally produced by hybridization, it seems 

 to be sufficiently well established now to propagate itself without 

 assistance from other flowers, for on one occasion only I found 

 a single tree of it when driving along a track through a forest of 

 E. sideroxylon near Reefton in the Temora district. I had no 

 time to examine either side of the road, and no trees of E. hemi- 

 phloia var. cdbens were in sight, though I afterwards found that 

 they were plentiful on a ridge a few miles to the eastward, but 

 cannot state the exact distance to the nearest tree. 



E. ajflnis may be found on ridges near Dubbo, Wellington,, 

 Peak Hill, Molong, Parkes, Grenfell and Temora, and, like E. 

 sideroxylon, has a decided preference for sedimentary formations. 



In giving all the above particulars my object has been to make 

 available any facts I have collected, without trying to prove any 

 theories for or against hybridization. One thing undoubtedly 

 seems evident, which is that the conditions which are favourable 

 to the production of both E. sideroxylon and E. hemiphloia var. 

 alhens are also suitable to E. affinis. 



In regard to the botany of the Pinnacle Mount, one feature 

 noticed was the presence of more species of the coast flora than 

 had been previously seen at any spot in coming fi'om Bourke, 

 representatives of the following genera being found for the first 

 time: — Brachyloma, Phyllanthiis, Calythrix, Dillwynia and 

 Zieria. Some other coast forms found here have been mentioned 

 in previous papers. 



From Pinnacle Mountain to Marsden, near Lake Cowal, via 

 Blink Bonnie, is about 30 miles south-westerly, being chiefly 

 plain country. The trees and shrubs noticed were as follows : — 

 Eremophila Mitchelli, Ileterodendron olecefolium, Callitris robusfa, 

 Myoporum desert i, Pittosporum phillyrceoides, Geijera pa.rvij{oray 

 Exocarpus aphylla (Stiff or Jointy Cherry), E. ciipi'essiforinis, 

 Hakea leucoptera (not plentiful), and Ajyophyllum anomalum 

 (Warrior Bush), which was very scarce.
