Botanical description. -Genus Acacia. See Part XV, p. 103. 
Botanical description. Species Bunowi Maiden, in Proc. Roy. Soc. N.S.W., 
liii, 227 (1919). 
Following is the original description : 
A medium-sized tree, up to 30 or 40 feet high, with a stem diameter up to a foot. Bark thin, 
furrowed, tough-fibrous; timber fissile, deep brown, and probably a useful furniture wood. The branchlets 
angular. 
PhyUodia narrow lanceolate to lanceolate, falcate or straight, narrowed at both ends but tapering 
more towards the base, mostly 4 to 8 cm. long, -15 to 1 cm. in the middle, coriaceous, striate with numerous 
very fine uniform nerves, three rather more prominent, all free from the lower margin from the base. 
Spikes shortly pedunculate, often clustered in the upper axils, 2-2-5 cm. long, rachis almost glabrous. 
Flowers rather densely packed, mostly 5-merous. Bract capitate. 
Calyx truncate or sinuate-toothed, pubescent near tips of the lobes, about half the length of the 
corolla. Petals glabrous, each marked with a faint line. Ovary hirsute. 
Pods shortly stipitate, linear 5-6 cm. long, 2-3 mm. wide, straight or nearly straight, valves deeply 
embossed to receive the seeds, which are longitudinally arranged. 
Seeds shiny, black, oblong, with a deep central areole, with a narrow funicle folded on itself several 
times, forming a thickish arillus slightly enveloping the top of the seed. 
Affinities. Its closest relations are A. argentea and A. glaucescens. 
1. With A. argentea Maiden in Proc. Roy. Soc. Q., xxx, 41. A. argentea is a 
slender shrub up to 10 feet high ; A. Bunowi is a small or medium sized tree ; the petals 
of the former species are reflexed and the calyx completely hairy; the seeds in the 
former are brown, in the latter black. While the species are undoubtedly different, 
there may be a good deal of similarity in the phyllodes and also in the pods. 
2. With A. glaucescens Willd. This is figured at Plate 145, vol. iv, of the present 
work. The species are allied, but in A. glaucescens the phyllodes are, as a general rule, 
larger and more glaucous, the calyx is smaller in proportion to the petals, both calyx 
and petals are more hairy, the floral bract is different, the spikes are larger, and the 
valves hairy.
