Knowledge of the flowering period is, however, often useful to people who have 
devoted particular attention to the wattles of a district. Sometimes the same tree 
flowers twice in a season, and the period of flowering is affected by climatic 
influences of a particular district, and a particular season.

Bark .—A not very good specimen from Campbelltown, stripped in August, 
yielded 3P5 per cent, of tannic acid, and 57’35 per cent, of extract. 
A specimen from Hyde, near Sydney, yielded 32-33 per cent, of tannic acid, 
and 48’74 per cent, of extract. 
Timber. —Of pale colour, more or less brown in the centre. Only useful for 
fuel, for which purpose it is appreciated for bakers’ ovens. 
Exudations. —The gum of this species contains a complex carbo-hydrate of 
the galacto-araban character, and does not differ essentially from gum-arabic, peacli- 
gum or cherry-gum.—Wintlirop E. Stone ( Amer. Chem. Journ ., XVII, 196-199 ; 
see also Journ. Soc. Chem. Ind., July, 1895, p. 667). 
Dr. Greig Smith, Macleay Bacteriologist, is engaged in a series of interesting 
researches on the origin of wattle and other gums, and has shown that these gums 
are of bacterial origin. His researches are published in the Proceedings of the 
Linnean Society of New South Wales. 
Size. —A small or medium sized tree, with a diameter of, say, 9 inches, and 
a height of 25 to 30 feet. 
Habitat. —Apparently confined to New South Wales, and restricted to the 
eastern portion of it. 
It is a coast and coast-mountain variety, occurring chiefly about Port Jackson, 
Campbelltown, Picton and Bargo Brush, Berrima to Wollondilly, to Goulburn and 
Taralga. 
Its southernmost locality in the National Herbarium is Bateman’s Bay, but 
I have no doubt it extends further. 
I do not think I have seen it north of Port Jackson.
