216 NOTES ON NATIVE FLORA OF NEW SOUTH WALES, IIL, 



harpophylla, F.v.M. This latter tree was not seen near Gilgandra, 

 but northerly towards Coonamble it becomes common. 



Of the Eucalypts, the Box-trees predominate, especially E. 

 populi/olia, E. conica, and E. Woollsiano. The latter was noticed 

 to have very narrow leaves and small fruits, and towards the 

 western margin of the habitat of this species the character seems 

 accentuated, while towards the eastern edge, which to the south 

 of Wellington is near the foot of the western slopes, the leaves 

 and fruits increase in size. In these Proceedings for 1904 (id.764) 

 Mr. J. H. Maiden has suggested that these two forms might be 

 regarded as separate species; but in travelling through the 

 western districts I have found it difficult to decide on a line of 

 demarcation between the two forms, the change in size of leaves 

 and fruits appearing to be gradual, as suggested above. In one 

 spot on Bongeabong, seedlings of E. WooUsiana were found 

 covering an area of about 100 acres and forming a thicket as 

 dense as a Mallee scrub. 



E. largijiorens, F.v.M., a River Box with rough bark on the 

 branches and often a silvery drooping foliage, was not seen at 

 Gilgandra, but specimens were procured on the Marthaguy near 

 Bongeabong, which spot marks a point on the eastern margin of 

 the habitat of this species. North-westerly from here, towards 

 the Darling River, this tree becomes common. 



E. conica was noticed to be flowering throughout the Dubbo- 

 Gilgandra district in October, 1904, and from observations made 

 on the Lachlan the species was usually found flowering there in 

 the Spring months also. 



E. hemiphloia, var. albens, the common large glaucous-lea\'ed 

 White Box of the western slopes, was scarce around Gilgandra, 

 the western margin of its range being almost reached. 



E. melliodora, Yellow Box, was seen only near the banks of 

 the Castlereagh River, the species being one which gradually 

 leaves the hills as the far west is approached, reaching its most 

 western points by following down the river flats. This tree is 

 generally indicative of a fairly good soil, and in some districts 

 selects the very best.
