40 R. H. CAMBAGE. 



an extensive range at least from Bathurst to Cooma, a 

 distance of about 200 miles, it is not known in the inter- 

 vening area, and is looked upon as rare in both localities. 

 The available evidence regarding this tree points to the 

 conclusion that it is probably a vanishing species. 



E. cordata of Tasmania is a very similar little tree and 

 has adopted the vegetable wax instead of the vertical leaf. 

 The species is confined to Tasmania and even there is not 

 regarded as plentiful. It seems not unlikely that in the 

 near geological future both these species will have dis- 

 appeared. 



E. cinerea of the Goulburn district is somewhat similar 

 to the two former, but appears to be past the critical stage. 

 It has covered its leaves with glaucous powder, and 

 although some trees are furnished with opposite orbicular 

 and broadly ovate leaves only, others have developed many 

 lanceolate leaves which hang vertically. It grows to a 

 height of 40 or 50 feet, has a fairly considerable range, and 

 its stems are covered with thick shortly-fibrous bark, while 

 the two former have smooth bark. 



The remarks in regard to B. cinerea apply generally to an 

 interesting species known as Silver-leaved Ironbark, E. 

 melanophloia, except that the latter has a hard furrowed 

 bark. 



Juvenile leaves. — Under the designation of juvenile 

 leaves may be included not only seedling leaves, but also 

 most of those of certain adventitious growths abundantly 

 produced by cutting or wounding parts of the barrel or 

 branches, and which in Australia are popularly known as 

 suckers, and the difference between these leaves and the 

 mature or adult foliage of the same tree is often so great 

 as to convey the impression to one who has not studied the 

 genus, that they belong to distinct species. It is remark- 

 able that Eucalypts rarely, if ever, produce true botanical
