it seems to give place to a smaller and paler coloured form 

 of Box Tree (No. 4162) which was found intermittently as 

 far west as the Flinders and Oloncurry Rivers. E. lepto- 

 phleba is a Box tree with a rather thick bark and long 

 leaves, the rough bark extending to the branchlets. The 

 timber is reddish-brown with a fairly thick sapwood. It 

 seems to favour the low, rather than the hilly land. 



E. alba (Poplar Gum) is fairly common along the coast 

 and was noticed as far inland as towards Dimbulah. It is 

 a white gum with very large juvenile leaves, measurements 

 of nine by six inches being not uncommon. It appears to 

 often grow on a granite formation which contains about 

 70° silica. A note taken at Townsville, while near trees 

 of this species, reads: — white to the ground, bark peels off 

 in short flakes, buds often have double operculum. 



Small trees about twenty feet high of various species of 

 Grevillea were fairly common throughout. G. polystacliya 

 with beautiful creamy flowers, and G. clirysodenclron with 

 charming yellowish-red flowers were the most conspicuous. 

 G. glbboscv was first noticed near Biboohra after which it 

 was seen the whole way. It is known as Beef Tree or 

 Beefwood owing to the appearance of its timber, which is 

 prettily marked with medullary rays, a common feature of 

 the timbers of the Natural Order Proteaceae. For a species 

 of Grevillea its orbicular, gibbous fruits are somewhat 

 remarkable for their shape and size, the longer axis some- 

 times measuring as much as two and a quarter inches. 

 This species was not flowering in August but was con- 

 spicuous by its silvery looking leaves. 



Casuarlna suberosa (Black Oak) and C. torulosa (Forest 

 Oak), were not noticed for more than twenty miles west of 

 Kuranda. These are both well known coastal species, the 

 former extending south to Tasmania, while the latter does 

 not occur much to the south of Sydney.
