In other words, it comes from the extreme north of Australia, extending from 

 north Western Australia through the Northern Territory. It is a little known species, 

 and search will doubtless greatly extend its known range. I have submitted imperfect 

 evidence that it may belong to South Australia, at no great distance from the Northern 

 Territory border. 



The timber and bark of a tree are important in the definition of a species, and it 

 would be very desirable if there could be obtained short logs (say a foot long) of all 

 the Northern Territory species. Bearing in mind their friable character, the barks 

 should be tightly lashed round with sacking before beginning to cut them with a saw or 



an axe. 



Western Australia. 



Copeland Island, North-west Coast (Allan Cunningham). 



Northern Territory. 



I have seen, in addition to the type in the Vienna Herbarium, specimens from 

 J. J. Bennett's British Museum distribution of 1876, and labelled " 4781. R. Brown. 

 Island, Carpentaria, 1802-5." These are co-types, but with most of the leaves more 

 lanceolate than in the type. I have it also, " Medium sized tree," Glencoe Station, 

 Arnhem's Land. (N. Holtze, from Melbourne Herbarium), and — Sandstone Ranges 

 near Western Creek, Northern Territory, 16th February, 1912. Rough scaly bark. 

 Buds and flowers only (G. F. Hill. No. 778). 



(?) South Australia. 



In the collections of the Elder Exploring Expedition, Wa-Wee Rockhole (Richard 

 Helms, 24th May, 1891), are some fruits (I suppose there must have been leaves collected, 

 but I have never seen any), some of which have been distributed under the name 

 "Eucalyptus tesselatis" (in Mr. Helms' handwriting), evidently a slip foi E . terminalis 

 F.v.M. recorded in Proc. Roy. Soc. N.J . xvi, 358. 



The fruits have a smooth surface, and are of precisely the shape and size of 

 specimens from Glencoe, Northern Territory, figured at 4b, Plate 159 (E . ferruginea). 

 They are certainly not E. terminalis. The localities for ' ; E. terminalis'''' quoted 

 (op. cit.) are, South Australia, Mount Goolwa (C. 6), Everard Range and Wa-Wee 

 Rockhole ; West Australia, Cavenagh and Barron Ranges, and between them in patches. 



As I have only seen the Wa-Wee Rockhole specimens, I cannot say to what 

 species the specimens from the other localities should be attributed. 



On the 24th May, 1891, the expedition (Journal, p. 21) was a stage from the 

 Arcoelinna Well, having left the Warrina Railway Station (near Oodnadatta) on the 

 1st instant, and proceeded via Arkaringa Creek. 



On this imperfect evidence I suggest that E. ferruginea may occur in South 

 Australia (near the southern boundary of the Northern Territory). It is not an impossible 

 locality, and I hope that collectors will give their further attention to the trees of the 

 Territory.
