for cemeteries on account of its pendent branches. It flowers almost 

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

 Wood very durable, locally much used for implements and especially 

 wheelwright's works [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-coloured, hard, heavy and durable, well adapted for furniture 

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

 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. 



Indigenous to Southern Asia ; found eastward as far as Japan ; a 

 native also of the warmer parts of Australia, as far south as the 

 Darling-River ; found spontaneous in tropical and sub-tropical 

 America, but apparently not in tropical Africa. The scented flowers, 

 inappropriately called 6< cassie " flowers, are much sought for per- 

 fumery, and develop successively. 100,000 Ibs. of these flowers are 

 annually gathered near Grasse in France. This species may well be 

 utilised 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 Ordinarily the odorous essential oil is withdrawn from the flowers by 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 

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

 soil and in the hottest clime. It produces a portion of the Cape-Gum. 



Acacia glaucescens, Willdenow. 



Queensland and New South Wales, in mountain-regions up to 

 3,000 feet. Extreme height about 70 feet. A kind of " Myall," 

 with hard, dark, elastic, prettily grained wood, which is however less
