568 BOTANY OF THE INTKRIOR OF NEW SOUTH WALES, 



^' Flora of Mount Kosciusko"). It is common along the highlands 

 of New South Wales, both north and south, extending also into 

 Victoria and Tasmania. It is the Snow Gum of the Kiandraand 

 Kosciusko districts, where it often grows in a stunted form. A 

 conspicuous feature in the general appearance of this tree is its 

 large coarse, longitudinally veined, and somewhat shining leaves, 

 which in times of drought are considered to be moderately good 

 fodder, and this in some places has earned for the tree the name 

 of Cattle-gum. Its fruits are fairly large, and in the Oberon 

 district the seeds are eaten by the Gang Gang Cockatoo {Callo- 

 cephalon galeatiim^ Latham). The bark of this tree is usually 

 smooth and white to the ground, also thin, and when growing 

 with E. viminalis bushmen can separate the two species on sight 

 by the bark and foliage. The timber of E. coriacea is one of the 

 best of the cold country gums, and is often used for fence posts. 

 This species is not restricted to any particular geological formation, 

 but seems to have a preference for igneous over sedimentary, and 

 is usually found growing in open forests. It shares wdth some 

 other trees the names of White Gum, Cabbage Gum, and Scribbly 

 Gum. The latter name is suggested by certain scribble marks 

 on the bark, and these are made by a small grub eating its way 

 along the outside of the inner bark, the eiFect being that the 

 " scribble " is left thereon; also on the inside of the outer bark, 

 the outside of which was perhaps previously operated upon while 

 it was yet inner bark, so that a piece of bark just falling off will 

 often have scribble marks on both sides, but in no w^ay connected 

 with each other. A casual examination once made of this little 

 grub in the Oberon district showed it to measure only two. lines 

 in length. E. lutmastoma is another white gum tree which also 

 has has scribble marks on the bark. 



E. rubida is also one of the high country gums, and is some- 

 times found associated with E. viminalis, with which species it 

 is often confused by bushmen. Of the two species, E. ruhida 

 generally takes the drier land, being found on hillsides, while E. 

 viminalis is more plentiful in the valleys; but it is also quite 

 common to see them mingle on elevated land. As a rule E.
