In a paper* Mr. R. T. Baker has emphasised this leaf-variation, and gives 

 figures. I have figured small pieces of Bentham's specimens (these are hetero- 

 blastic, i.e., with the juvenile and adult leaves different, as with most Eucalypts), 

 at figs. 13-15 of PL 53, while what may he termed the normal form (homoblastic, 

 with the juvenile and adult leaves similar) will be found figured on PL 54, tigs. 1-4. 



Mr. E. Maher, of Collaroy, gave me the name " Ginghi " as the native name 

 for this tree on the Macquarie. I have received the name " Ghinghit " from the 

 Dubho district, hut cannot understand the difference between the two words. 



RANGE. 



In the original description the localities given for this species are : — 



(a) Newcastle Bange to Moreton Bay, accompanying E. crebra, and 

 indicating sterile soil. 



(b) Sub-tropical New Holland (Mitchell). "March 5, 1816. No. 485. 

 Ironbark. Sub-tropical New Holland. Lieut.-Col. Sir T. L. Mitchell. E. 

 pulverulenla, aff. H." (Hooker). Copy of a label in Herb. Cant, ex Herb. Lindl. 

 This is E. melanophloia. 



Mitchell, see his "Journal of an Expedition into the Interior of Tropical 

 Australia," p. 80, and map, was, on that date, at the " Springs of Carawy," in 

 lat. 30 c S. and, say, 148° 30 ' east longitude, a little to the north of Walgett, New 

 South Wales. 



(c) Moreton Bay, Moore, No. 66 of the " Sydney " woods, Paris Exhibition 

 (1855). The word " Sydney " may be misleading. The collection was got 

 together in Sydney, but the original label is " The Silver-leaved Ironbark of the 

 Northern Districts " (which in this particular instance referred to Moreton Bay, 

 Queensland not having been proclaimed a separate colony). 



It is very extensively distributed in the drier parts of New South Wales 

 and Queensland. Eollowing are some localities represented in the National 

 Herbarium, Sydney : — 



New South Wales. 



" Silver-leaved Ironbark," Dubbo (J. L. Boorman) ; Tomingley to Narromine, 

 fruits very small (J.H.M.) ; Mulungerebar, Coolabah ; also Willeroon, only a few 

 in the district (R. W. Peacock) ; Eord's Bridge, 41 miles west of.Bourke, on red 

 sandy ridges (A. Murphy) ; Bourke district (O. C. Macdougall). 



" Silver or Broad-leaved Ironbark," Narrabri (Henry Deane, J. L. Boorman, 

 J.H.M.) ; Gundy, near Scone, the most easterly recorded locality (J.H.M.) ; 

 Walroodah, Barraba (R. D. Hay) ; " Narrow-leaved form," Howell, near Inverell 

 (E. C. Andrews).
