6 Select Plants for Industrial Culture and 



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 ; suit- 

 able 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, Beutham. 



The Tronbark-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, Will den ow. 



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 " 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 Ordinarily the odorous essential oil is withdrawn from the 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 

 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.
