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

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

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

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

 with the juvenile and adult leaves similar) will be found figured on PI. 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 

 Dubbo district, but cannot understand the difference between the two words. 



RANGE. 



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



(a) NcAvcastle Range to Moreton Bay, accompanying J^. crehra, and 

 indicating sterile soil. 



(b) Sub-tropical New Holland {Mitchell). "March 5, 1846. No. 485. 

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

 pulcerulenta, 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. 80^ 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) ; Pord'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 Inyerell 

 (^. C. Andrews).
