Reference should be made to Plate 153, Part XLI, and Plate 57, Part XV. It 
should again be noted that Mueller originally confused the pods of A. mdanoxylon 
with those of A. Maidenii, which would have made the similarity of A. Maidenii to 
A. melanoxylon and A. implexa closer than it really is. 
Botanical Name. Acacia, already explained (See Part XV, p. 104); Maidenii, 
in honour of the writer of these lines. 
Vernacular Names. Mr. Bishop Lyne, of Narrabri, gave me the name 
" Motherumbung " for this wattle, but as this is shared by others, e.g., A. Cunninghamii 
Hook and A. penninervis Sieb., it is not specially appropriate. 
"Sally" (sometimes "Broad-leaved Sally"), and "Hickory" are both applied 
to it, but both are applied to more than one species, and to in each case a better known 
species. I know no distinctive name actually in use except the modern one I have 
adopted. 
Bark. Some years ago Mr. H. G. Smith analysed a sample from Lismore, 
collected by Mr. W. Baeuerlen. He found 35' 5 per cent, of extract, and 15' 75 per cent, 
of tannic acid. The bark is therefore but an inferior yielder of tanning material. 
Flowers. The flowers are of such a pale yellow colour that the species will 
never become popular because of its flowers alone. 
Fruit. A further word of caution as to the original confusion which arose 
in regard to the fruits of this species. 
(jails. " A young Sally is a handsome and graceful- looking tree, but soon 
after maturity it becomes infested with the galls of a small wasp, which has been 
identified by Mr. W. W. Froggatt as Trichilogaster Maideni Froggatt, and these galls 
soon cover the smaller branches and finally quite disfigure the tree." (B. H. Cambage 
in Proc. Linn. Soc. N.S.W. xxxvi, 565, 1911). 
Timber. It yields an inferior timber for constructional purposes, and used 
only, as far as I know, for fuel for bakers' ovens. 
Exudation. A specimen of gum, collected at Woodburn, N.S.W., was reported 
upon by Mr. H. G. Smith in the following words : 
" It is in small pieces of a light amber colour, rather brittle, with very bright fracture, but without 
the dark-brown objectionable portions so common in the Acacia gums, especially A, decurrens. When 
treated with cold water, almost the whole of the gum slowly goes into solution, forming a very pale-coloured 
liquid which is very adhesive, of good body or having a high viscosity. It is, however, rather tedious to 
dissolve. The solution is slightly acid to test paper. It forms a solid cream-coloured jelly with ferric 
chloride, thus showing absence of tannin. It does not thicken with borax solution, nor doea it undergo 
any change with mercuric chloride. It gives a precipitate with basic acetate of lead. It gives a dense 
white precipitate with alcohol in acid solutions. It slightly darkens to a canary colour when warmed with 
dilute soda solution. It contains 16-15 per cent, water and 4-67 per cent, ash; the ash consists principally 
of the carbonates of lime and manganese and potassium, with sulphuric acid, and only the merest trace of 
phosphoric acid. The ash contains fusible salts and is difficult to incinerate; it contains only a trace of 
manganese. (Journ. Roy. Soc. N.S.W. XXIX, 400, [1895].) 
Size. A tree of medium size, good shape, and umbrageous. It is well worthy 
of a place in any collection of the larger Wattles in gardens in the coast districts.
