782 NOTES OS THE NATIVE FLORA OF NEW SOUTH WALES, II., 



crebra, F.v.M. (Narrow-leaved Iron bark), £J. trachyphloia, F.v.M. 

 (Blood wood), and E. rostrata, Schl. (River Red Gum), the latter 

 being seen along the banks of the Namoi River near Narrabri. 



The Bloodwood trees were noticed on sandstone formation 

 between Turrawan and Tibberena, but the species could not be 

 identified with certainty from the train, and may possibly be B. 

 coryrnhosa^ Sm., though as the first of these has already been 

 recorded from Narrabri, and also occurs near Coon abarab ran, it 

 seems probable the tree referred to above is E. trachyphloia. 

 This area of sandstone came rather as a surprise in the locality, 

 and was made further interesting by the fact that on 

 it was growing a quantity of Angophora lanceolata, Cav., the 

 smooth-barked Apple, or so-called Red Gum of the Sydney 

 district, the latter name being adopted because of the reddish 

 exudation which commonly stains the otherwise dull whitish 

 bark. The occurrence of the species in this and other isolated 

 spots so far west is marked evidence that the geological forma- 

 tion at times undoubtedly affects the distribution of species. The 

 home of this tree is on the Hawkesbury and Permo-Carbonifer- 

 ous sandstones around Sydney and Newcastle, but it occurs in 

 various localities, though usually on similar formations, to the 

 north and north-west. 



Among other trees and large shrubs noticed between Boggabri 

 and Narrabri w^ere : Callitris rohusta, R.Br. (White or Cypress 

 Pine), C. calcarata, R.Br. (Green or Black Pine), Dodoyuea sp., 

 Eremophila Mitchelli, Benth. (Sandalwood or Budtha), Cassias^.,

 parviflora, Lindl. (Wilga), Heterodendron oleccfolium, Desf . (Rose- 

 wood, a very hard timber), Acacia har2'>ophylla, F.v.M. (Briga- 

 low), A homalophylla, A. Cunn. (Yarran), Canihium oleifolium^ 

 Hook. (Wild Lemon), Exocarpus ciq^ressiformis, Labill. (the so- 

 called Native Cherry), Xanthorrhcea sp. (Grass Tree), and San-

The only trees seen of Casuarina Cuiininghamiana, the River 

 Oak, were growing along the banks of the Namoi at Narrabri,
