6 Select Plants for Industrial Culture and 



fragrant than that of some other species. The flowers have a 

 strong agreeable scent. The bark is locally used in a decoction to 

 destroy Aphis and other minute parasites on cultivated plants ; the 

 aborigines used it for stupefying fish [Crawford]. 



Acacia G-reggii, Asa Gray. 



From Southern California to Arizona and Texas. A small tree, 

 allied to A. Wrightii (Bentham) of the Rio Grande-region. A 

 kind of lac is copiously obtained from this tree in the Mojave- and 

 Colorado-Deserts [Prof. Stilman]. This plant lives at a rainfall of 

 3 inches a year. 



Acacia gummifera, Willdenow. 



This tree yields principally the Gum Arabic of Morocco [Sir 

 Joseph Hooker and John Ball]. The principal collecting time 

 extends over six weeks in midsummer. 



Acacia harpophylla, F. v. Mueller. 



Southern Queensland. A tree, sometimes attaining a height of 

 90 feet, furnishing locally a considerable share of the mercantile 

 wattle-bark for tanning purposes, particularly for light leather. 

 Wood, according to Mr. P. O'Shanesy, brown, hard, heavy -and 

 elastic, somewhat of violet odor ; it splits freely and is thus also 

 well adapted for fancy lathe-work ; used by the natives for spears. 

 The tree grows naturally on sand-lands, almost to the exclusion of 

 other trees and shrubs. Saplings, used as stakes in vineyards, 

 have lasted 20 years and more. The tree yields also considerable 

 quantities of gum. It is one of the principal a Brigalows " in the 

 scrubs of that designation. 



Acacia heteroclita, Meissner. 



South-Western Australia. This or an allied species furnishes a 

 particular sort of edible gum, called by the autochthones " Quannot " 

 [Sir John Forrest]. 



Acacia homalophylla, Cunningham. 



The principal " Myall," extending from the desert of South- 

 Australia into New South Wales. Never a tall tree. The dark- 

 brown wood is much sought for turners' work on account of its 

 solidity and fragrance ; perhaps its most extensive use is in the 

 manufacture of tobacco-pipes. Allied species pass under the abori- 

 ginal appellation " Boree/" Some or most will grow in the bleakest 

 and most arid localities, wherever frost is not severe. 



Acacia horrida, Willdenow. 



The " Doornboom " or " Karra-Doorn " of South- Africa. A for- 

 midable hedge-bush with thorns often 3 inches long, readily avail- 

 able for impenetrable hedge-rows. It exudes also a gum of good
