and serves to illustrate the wonderful, though perhaj^s gradual, 

 adaptability of plants to environment. 



C. nana was common on part of Kydia Mountain, and on the 

 Main Divide, occupying the latter almost exclusively for some 

 considerable distance. 



Eucalyptus maculosa (sometimes called Spotted Gum) was 

 noticed between the Umaralla River and Dangelong. This 

 species does not appear able to withstand the extreme cold of 

 high altitudes so well as E coriacea or E. rubida, and occupies 

 chiefly the central and western side of the mountain-area from 

 the Upper Hunter southerly, extending into Victoria at least as 

 far as Ballarat. Tt is of ten associated with E. (iii;/^s( Peppermint). 



Eucalyptus Moorei was found growing in Mallee-like form in 

 the open gullies just on the eastern side of the Main Rauge, on 

 the actual head-waters of the Tuross River, and seemed confined to 

 the siliceous conglomerate-formation. Except that the foliage, 

 chiefly the juvenile growth, is somewhat broader than that of the 

 type, it otherwise corresponds exactly with the Blue Mountain 

 shrub; and in both cases is growing near the summit of the 

 mountain-zone on highly siliceous geological formations, very 

 slightly favouring an eastern or coastal aspect, but with more 

 rigid climatic conditions at Kybean than at Blackheath. In no 

 case does it appear to attain the dignit}^ of a tree, reaching, at 

 Kjbean, a height of 10-12 feet, with a diameter of 2-5 inches. 

 Typical E. stellulata, which it resembles in herbarium material 

 whon juvenile foliage is absent, was growing some 3 or 4 miles 

 off, up to 50 feet high, with a diameter of 2j feet, and having 

 very broadly ovate, or in some cases almost orbicular " suckers." 



Another Mallee-like Eucalypt,-'" 6-10 feet high, was noticed in 

 patches on the bald conglomerate-hills, and appears to be similar 

 to a form found in very limited quantity at Blackheath by Mr. 

 Maiden and myself, and referred to as Form C, in tliese Proceed- 

 ings for 1905 (p. 201). This plant, which was in full flower at 

 the end of October, will be further investigated by us.
