height of 15 or 20 feet, diameter 4 to (Jin., and as a rule 
rather sturdy in trunk for its height. The younger branches 
are very iirominenbly angular and more or less striate 
on the flattened areas. The tips of the young phyllodia 
are reddish purple and very tender ; mature phyllodia 
B to 5in. long, tapering at both ends, from J to Uin. 
broad in the centre, prominently 3-nerved witli multitudinous 
secondary parallel nervelets running the full length of the 
phyllode often confluent before reaching the petiole proper. 
Cylindrical flower spikes axillary, solitary or as many as three or 
four together, obliquely erect and straight, 2.V or Bin. long and 4 
lines wide ; flower ot a bright sulphur ; young buds pyriform, 
packed closely to the rachis, If abortive, as often happens in 
one crop of bloom of the black wattles, the cluster of spikes hang 
to the tree for several weeks and turn a dull red-brown. Tlie 
legumes become very flexuose, and are long and narrow, only 
about U to 2^ lines broad. Jn flower in July and August, 
fruiting probably in November or December, It is the “ Black 
Wattle y and ‘ ‘ Dastard Myall ’ ^ of New South Wales and the ‘ ‘ Black 
Wattle ” and Kowarkul of Queensland, the latter a native name. 
Dr. T, h. Bancroft says “ This species is tlie only tanning wattle 
which grows near Brisbane in any great abundance. ’ ’ A specimen 
forwarded by him to Mr. Maiden from Deception Bay gathered 
from^a tree a foot in diameter gave 12-BB per cent, of acid aud 
26-05 of extract. The bark is about half an inch thick, under 
the outer dark brown scaly portion, and is fibrous within- 
1 am not aware that it has been utilised at the Warwick tannery, 
probably the natural growth is too scarce. Another analysis at 
tie Indian and Colonial Exhibition, relating to a Queensland 
sample, only gives 9 per cent, of tannin and 16*15 per cent, of 
extract.
