Acacia.] XLIII. LEGUMINOSHC. 499 
The pods on the Queensland tree agree better with the above description than with Mueller’s 
plate above quoted. 
Wood prettily marked, the outer light-coloured, the heartwood greyish-brown ; a useful 
cabinet wood. — Bailey's Cat. Ql. J Foods No. 136. 
62. A. harpophylla (boomerang-shaped), F. v. M. Herb Benth. FI. Austr. 
ii. 389 ; F. r. M. Ic. Dec. vi. 9. Brigalow. “ Ogarah,” St. George, Wedd. 
A large tree, glabrous or the young shoots minutely hoary ; branchlets slightly 
angular. Phyllodia falcate-lanceolate, mostly 6 to 8in. long, narrowed but obtuse 
at the end, much narrowed at the base, coriaceous, pale or glaucous, with several 
not very prominent nerves and scarcely veined between them. Peduncles slender, 
i to fin. long, clustered or rarely in a very short raceme, bearing each a small 
globular head of about 12 to 15 mostly 5-merous flowers. Sepals spathulate, not 
half as long as the corolla, free or slightly connected below the middle. Petals 
smooth, free. Pod narrow, 5 to Gin. long, slightly contracted between the seeds, 
sharp at the apex. Seeds longitudinal. 
Hab.: Rockhampton, Tliozet. A very common inland species, forming large scrubs. 
Yields a light or dark-brown gum, which is entirely soluble in cold water, forming a mucilage 
as sticky as arabic gum. — Lauterer. 
Wood brown, close-grained, elastic, slightly scented, and durable ; a good cabinet wood. — 
Bailey's Cat. Ql. Woods No. 137. 
63. A. excelsa (tall), Benth. in Mitch. Trop. Austr. 225, and FI. Austr. ii. 
390. Ironwood Wattle. “Tooloo,” St. George, Wedd. A large forest tree; 
branchlets slender, terete or nearly so, glabrous or rarely minutely pubescent. 
Phyllodia oblong-falcate, rather obtuse or mucronulate, narrowed at the base, 2 
to 3in. long, ^ to fin. broad, thinly coriaceous, with 5 to 7 nerves, and smooth or 
faintly veined between them. Peduncles solitary, in pairs or clusters, sometimes 
not 2 lines, in other specimens nearly ^in. long, bearing each a globular head of 
numerous (20 to 30) flowers, mostly 5-merous. Sepals distinct. Petals smooth. 
Pod straight, flat, about 3 lines broad, thinly coriaceous, the sutures narrow- 
edged or almost winged, not usually dehiscent but hardening over the seeds and 
readily breaking off between them. Seeds ovate, longitudinal ; funicle short and 
filiform, neither folded nor enlarged. — A. Daintreana, F. v. M. Eragm. iv. 6. 
Hab.: Near Lake Salvator, Mitchell; Peak Downs, F. v. Mueller ; Clarke River, Daintree ; also 
in Bowman's collection. 
Very closely allied to, and perhaps a variety of, A. laurifolia , Willd., from New Caledonia and 
the Pacific Islands, differing chiefly in the narrower phyllodia and pods. — Benth. 
Wood very hard, dark and close-grained ; most useful where strength and durability are 
required. — Bailey's Cat. Ql. 1 Foods No. 137a. 
64. A. complanata (flattened branches), A. Cunn.; Benth. in Hook. Land. 
Journ. i. 369, and FI. Austr. ii. 390. A tree, glabrous ; branchlets flattened, 
bordered by 2 or rarely 3 acute angles or narrow wings. Phyllodia oval or 
oblong, obtuse, 2 to 3in. long, ^ to lin. broad, thinly coriaceous, with 5 to 9 or 
even more longitudinal nerves and a few fine veins between them. Peduncles 
slender, about -|in. long, in axillary clusters often of 6 to 8 or more, or by the 
abortion of the upper phyllodia forming an irregular terminal raceme, bearing- 
each a globular head of numerous flowers, mostly 5-merous. Sepals free, 
spathulate. Petals smooth, free. Pod curved, acuminate, very flat, 3 to 4 lines 
broad, the upper suture norve-like or with a narrow border. Seeds oblong ; funicle 
in the Banksiati specimens short and not dilated, but not quite perfect, in F. v. 
Mueller’s specimens elongated, more or less dilated from near the base, and 
encircling the seed in a single fold. — A. anceps, Hook. Ic. PI. t. 167, not of DC. 
Hab.: Endeavour River, Banks and Sola rider ; Wide Bay, Bidwill, Moore; Dumaresq River, 
A. Cunningham; Brisbane River, Fraser, F. v. Mueller, and others. 
Phyllodia often disfigured by the blight fungus Diplodia liclienopsis. — Cke. and Mass. 
Wood of a yellowish colour, tough, with a close grain. — Bailey's Cat. Ql. U'oods No. 137b.
