WATTLES AND WATTLE-BARKS. 
and the largest trees of the species are found, is in the Adelaide hills and 
plains, from Encounter Bay to Clare. Eor propagation purposes seed 
should, if possible, be obtained from trees grown within these limits. In 
some parts of the north of the Colony there is a narrow-leaved variety, with 
the stem and branches covered with a whitish substance, which is desirable 
should not bo propagated, as the tree is of slow growth, and does not attain 
payable dimensions.” (J. E. Brown. Beports.) 
Average height of typical form 20 to 25 ft., and diam. 0 to L0 in. (Brown.) 
Mr. Brown gives the life of this tree at from ten to twelve years, and 
states that it may he stripped from the sixth to the ninth year, according to 
circumstances. It lives longer in sandy soils than in clay ones. 
Mr. G. S. Perrin summarises the advantages of this species over A. decur - 
rens by stating that the former species is more amenable to culture, and can 
be pruned to a better shape, occupies less space in the plantation, and is 
much better stripped. 
Baron Mueller (Select Extvu-tropical Plants) says: Ibis tree, which 
attains a maximum height of about 30 feet, is second perhaps only to 
A. dccurrcns in importance for its yield of tanners bark ; the quality ot the 
latter is even sometimes superior to that ot the black wattle (A. mollissimd ), 
but its yield is less, as the tree is smaller and the bark thinner. It is of 
rapid growth, content with almost any soil, but is general!}' found in poor 
sandy ground near the sea-coast, and thus also important lor binding 
rolling sand.” 
In an earlier portion of this w'ork I have gone into the question of soil, 
&c. Generally speaking, it loves a warm climate, with only a moderate 
rainfall. It therefore will not usually ilourish at elevations over 2,000 it. 
I have already dealt with the matter of localities. It is essentially a 
South Australian species, though it extends into both A' ictoria and New r 
South Wales. 
14. Acacia amama , Wendl., B.E1., ii., 3GG. 
This tall shrub yields a good bark, which would be valuable if it Avere of 
large size. As it is, the dried bark is of the size of cassia-bark or coarse 
cinnamon. It is smooth, and yields a pale-coloured, rather fibrous powder. 
A sample from Tantawanglo Mountain, near Candelo, N.S.W., from shrubs 
8 to 12 feet high, with a diameter of 2 to 4 inches, and grown in granite soil, 
afforded 45*85 per cent, of extract and 23*5 per cent, of tannic acid. It 
was collected July, 18S9, and analysed April, 1S90. 
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. 
15. Acacia salicina, Lindl., B.PL, ii., 307. 44 Cooba, ’ or “ Ivoubaii. 
44 Native Willow.” “ Motjieiujhba.” 
Following is a condensed account of the analyses of two specimens of this 
bark recorded by me in Eroc. R.S. , N.S.ll'., 1S88, 2G8 : — 
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 £ inch. Extract, 35*28 
per cent.; tannic acid, 13*21 per cent.
