three feet in diameter, and about eighty feet high, affording 

 excellent material for fencing and rough buildings. Prom the 

 specimens which he kindly procured for me, I feel no hesitation in 

 referring them to the white-flowering variety of E. leucoxylon, 

 similar to that which is found on some parts of the Lachlan, and 

 also about thirty miles from Mudgee. This is, in fact, what 

 Eraser and others have called *' the common Iron Bark of the 

 interior," and although differing sometimes in the colour of the 

 flowers, the quality of the wood, and in the texture of the leaves, 

 it is nevertheless a well denned species, perfectly distinct from 

 the Red and White Iron Bark near the coast (E. sideropliloia 

 and E. paniculata). Not far from the spot where the Iron Bark 

 was growing, Mr. Innes collected a specimen of E. dealbata, a 

 tree with glaucous,white foliage, sometimes called "River 

 Gum," and sometimes " Grey Box." .This species is found in 

 rocky situations in the interior, and Dr. E. Mueller thinks it 

 may prove a variety of E. viminalis. The anthers are certainly 

 very similar, but in the latter, the flowers are more distinctly 

 pedicellate, and the leaves narrower and longer, whilst the fruit 

 is larger and not hemisphericaL According to the Report of "the 

 Victorian Exhibition of 1861, the wood of E. dealbata is almost 

 as good as that of the true Box (E. hemijphloia) ; but as opinions 

 vary as to the quality of the timber, it is not improbable that the 

 Victorian tree is either a distinct species, or a marked variety. 

 The same report also states that E. oleosa (E. uncinata, Bentham), 

 covers the vast tracts of level country towards the N.W. of 

 Victoria, forming with the species E. dumosa and E. socialis 

 (E. oleosa, Bentham), the dense masses of vegetation known as 

 Mallee Scrub. The dimensions of E uncinata require it to 

 be ranked as a shrub, as it rarely exceeds twelve feet in height ; 

 but from the circumstance that the individuals of the species 

 are clothed with foliage to the ground, and often grow so 

 closely together, as to form inpenetrable masses of vegetation, an 

 exceedingly large quantity of the leaves (which contain an essen- 

 tial oil of the greatest importance) can be procured in a short 

 space of time. (See Report of Victorian Exhibition, p. 32).
