WATTLES AND WATTLE-BARKS. 43 



I Lave already dealt with the matter of localities. It is essentially a 

 South Australian species, though it extends into both Victoria and New 

 South Wales. 



So-called delicate plants, such as this species, may be successfully grown 

 in rather cold districts, e.g., Blue Mountain, Moss Yale, &c., in New South 

 "Wales, by taking advantage of a fact well known to gardeners, viz., they 

 should be planted with a westerly aspect, so that the sun will not shine on 

 them to early after a severe frost. 



A New Zealand correspondent writes : " Pycnantha trees, 4 years old, 

 are 6 feet high, and 2 inches in diameter at 3 feet from the ground, in the 

 Auckland district of New Zealand. Land rather strong, with sand in it, 

 and on a clay sub-soil." 



In another instance in this district, the scrub was cut, the land ploughed 

 in strips, 10 feet apart, and the seed drilled in at the rate of 1 Ib. to the 

 acre. Since then the trees have been allowed to grow wild, never having 

 been thinned or the land cleared, or, in fact, having one penny spent on them. 

 In 6 years the best trees are over 10 feet high, and 3| inches in diameter, 

 and the decurrens trees are over 20 feet high, and 5 inches in diameter. 



15. Acacia amcena, Wendl., B.FL, ii, 366. 



This tall shrub yields a good bark, which would be valuable if it were of 

 large size. As it is, when dried, it is of the size of cassia-bark or coarse 

 cinnamon. It is smooth, and yields a pale-coloured, rather fibrous powder. 



A sample f rom Tantawanglo Mountain, near Candelo, N.S.AV., from shrubs 

 8 to 12 feet high, with a diameter of 2 to 4 inches, and grown in granite soil, 

 afforded 23'5 per cent, of tannic acid, and 45'85 per cent, of extract. It 

 was collected July, 1889, and analysed April, 1890. 



Pound in New South Wales and Victoria ; a coast and mountain species. 

 Its most northern limit in the former Colony appears to be the Moruya 

 district. 



16. Acacia saUcina, Lindl., B.M., ii, 367. 



" COOBA," or " KOUBAIL" " NATIVE WILLOW." " MOTHERUMBA." 

 Following is a condensed account of the analyses of two specimens of this 

 bark recorded by me in Proc. ft.S., N.S.W., 1888, 268 : 



a. Tarella, Wilcannia. Height, 20 to 25 feet ; diameter, 12 to 18 inches. 

 Collected' August, 1887 ; analysed August, 1888. A coarse, flaky bark, not 

 so fibrous, more compact, and altogether more promising looking than most 

 of the dry-country barks. Average thickness, up to f inch, taonic acid, 

 13-21 per cent. Extract, 35'28 per cent.
