Eucalyptus Raver etiana, F. v. Mueller.* 



Queensland. A jungle tree of the largest size, attaining a height 

 of 300 feet and 10 feet in diameter ; delights in the immediate 

 vicinity of rivers or swamps ; vernacularly known as Grey or Iron 

 Gum-tree. It furnishes a very hard, durable, dark-coloured wood, 

 valuable for piles, railway-sleepers, and general building purposes 

 (Thozet, O'Shanesy, Bowman). From cuts into the stem an acidu- 

 lous, almost colourless liquid exudes, available in considerable 

 quantity, like that from E. Gunnii. 



Eucalyptus redunca, Schauer.* 



The "White Gum-tree of "West Australia, the Wandoo ,of the 

 aborigines ; attains very large dimensions ; stems have been found 

 with a diameter of 17 feet. The bark is whitish, but not shining, 

 imparting a white coloration when rubbed. The tree is content 

 with cold flats of comparatively poor soil, even where humidity 

 stagnates during the wet season. It furnishes a very pale, hard, 

 tough, heavy and durable wood, highly prized for all kinds of wheel- 

 wrights' work, and especially supplying the best felloes in West Aus- 

 tralia. The seasoned timber weighs about 70 Ibs. per cubic foot. 



Eucalyptus resinifera, Smith.* 



The Red Mahogany Eucalypt of South Queensland and New South 

 Wales. A superior timber tree, of large size, according to the Rev. 

 Dr. Woolls, the wood being much prized for its strength and dura- 

 bility. It has proved one of the best adapted for a tropical clime, 

 although not so rapid of growth as some other species. It grew 45 

 feet in ten or twelve years at Lucknow, according to Dr. Bonavia, 

 but in the best soil it has attained 12 feet in two years. Proved in 

 Italy nearly as hardy as E. amygdalina and E. viminalis, according 

 to Prince Troubetzkoy. 



Eucalyptus robusta, Smith.* 



New South Wales, where it is known as Swamp-Mahogany by the 

 colonists. It attains a height of 100 feet and a girth of 12 feet, 

 with a barrel up to 50 feet in length, bearing a really grand crown 

 of foliage. The wood is strong and very durable ; reckoned a very 

 good timber for joists, also used for ship-building, wheelwrights' work, 

 and many implements, such as mallets. The tree seems to thrive 

 best in low sour swampy ground near the sea-coast ; where other 

 Eucalypts look sickly, E. robusta is the picture of health ( W. Kirton). 



Eucalyptus ro strata, Schlechtendal.* 



The Red Gum-tree of Southern Australia and many river-flats in 

 the interior of the Australian continent, nearly always found on 

 moist ground with a clayey subsoil. It will thrive in soil periodi- 

 cally inundated for a considerable time, anj^y on 4B slightly saline
