in Extra-Tropical Countries. 5 



Acacia estrophiolata, F. v. Mueller. 



Central Australia. A tree, attaining a height of 30 feet and a stem- 

 diameter of 1 foot, enduring the extremest of dry heat; suitable for 

 cemeteries on account of its pendent branches. It flowers almost con- 

 stantly, and accommodates itself to all sorts of soil, even sand. Wood 

 very durable, locally much used for implements and especially wheel- 

 wright's work (Rev. H. Kempe). Bark rich in tannin. 



Acacia excelsa, Bentham. 



The Ironbark-Acacia of Queensland, extending into New South 

 Wales. Attains a height of 80 feet. Branches pendent. The wood 

 is dark-colored, hard, heavy and durable, well adapted for furniture 

 and implements ; towards the centre it is of a deep pinkish color. 

 The tree exudes a large quantity, of clear gum (O'Shanesy), and 

 sprouts again from the root after the stem is cut. Also particularly 

 eligible for cemeteries. 



Acacia falcata, Willdenow. 



Extra-tropical East-Australia. A small tree. Important for its 

 bark in tanneries. 



Acacia Farnesiana, Willdenow. 



Dioscorides' small Acacia. Indigenous to Southern Asia; found 

 eastward as far as Japan; a native also of the warmer parts of Aus- 

 tralia, as far south as the Darling-River; found spontaneous in tropical 

 and sub-tropical America, but apparently not in tropical Africa. 

 Professor Fraas has recognized in this Acacia the ancient plant. The 

 scented flowers, inappropriately called "cassie" flowers, are much 

 sought for perfumery, and develop successively. This species may 

 well be utilized as a hedge-plant ; a kind of gum arabic may also be 

 obtained from it. The scent perhaps obtainable from the fresh and 

 slightly moist flowers by gentle dry distillation under mere steam-heat. 

 Ordinarily the odorous essential oil is withdrawn from the flowers by 

 the enfleurage-process ; many Australian Acacias might be thus 

 treated for perfumery. 



Acacia fasciculifera, F. v. Mueller. 



South-Queensland. Tree, sometimes to 70 feet high; branches 

 pendent. Desirable for culture on account of the excellence of its 

 easily worked dark wood. Eligible also for cemeteries. 



Acacia giraffae, Willdenow. 



South- Africa. The Camel-Thorn. This tree attains a great age 

 and a height of 40 feet. The trunk assumes a large size, and sup- 

 plies a wood of great hardness. The tree will grow on the driest 

 soil and in the hottest clime. 



Acacia glaucescens, Willdenow. 



Queensland and New South Wales. Extreme height about 60 feet. 

 A kind of " Myall," with hard, dark, prettily grained wood, which 

 is however less fragrant than that of some other species.
