[A racia . 
prominent nerves almost confluent with the lower edge near the base, and 
numerous fine parallel veins scarcely anastomosing and not very closely packed. 
Spikes shortly pedunculate , t oblong-cylindrical, dense, about -4in. long. Flowers 
mostly 5-merous. Calyx half as long as the corolla, shortly-toothed. Petals 
distinct, smooth, without prominent midribs. Pod narrow-linear, straight, 1 to 
14-in. long, 14 line broad, thin and flat with nerve-like margins. Seeds longi- 
tudinal ; funicle dilated and once folded under the seed. 
Hab.: Allied in some respects to A. Cun ning h amii. — Benth. 
80. A. longifolia (long-leaved), Willd. Spec. PI. iv. 1052 ; Benth. FI. Austr. 
ii. 397. An erect shrub, sometimes low and bushy, but attaining often a con- 
siderable size or growing into a small tree, glabrous or slightly pubescent when 
young ; branchlets angular. Phyllodia from broadly oblong to oblong-lanceolate 
or linear, very obtuse or almost acuminate, usually narrowed towards the base, 
with 2 to 5 more or less prominent longitudinal nerves and conspicuously or 
faintly reticulate between them, varying in length from 2 to Sin. in some varieties, 
to 5 or Gin. in others. Spikes axillary, loose and interrupted, flowers not imbri- 
cate, almost always 4-merous. Calyx very short, toothed. Petals smooth, united 
at the base or sometimes quite separating. Pod linear, often several inches long, 
2 to 4 lines broad or rarely more ; valves coriaceous, convex over the seeds, 
usually contracted between them. Seeds longitudinal, often distant, funicle not 
much folded, thickened almost from the base into a turbinate almost cup-shaped 
aril at the base of the seed, and sometimes nearly as large. — F. v. M. PI. Viet, 
ii. 80; Maid, and Camp. FI. PI. N.S.W., No. 9. 
Hab.: Moreton Bay, .-1 . Cunningham, and many other southern localities. 
At Toowoomba called Black Wattle. In tanning only used for light skins. Staiger found the 
bark to contain 12-67% of tannin. 
Wood towards the outside yellow, the inner brown, streaked with black ; tough ; easy to work 
A good cabinet wood. — Hailey's Cat. Ql. Woods No. 139. 
Under the name of A. longifolia, I have followed F. v. Mueller in including the following 
forms, which, different as they generally appear, are connected by such a gradual chain of 
intermediates that they cannot be separated by any positive characters. — Benth. 
Yar. Sophone, F. v. M. PI. Viet. ii. 30. Phyllodia obovate-oblong, very obtuse, coriaceous 
about 2 or rarely 3in. long, h to lin. broad, smaller veins reticulate. Calyx rather larger than in 
the other varieties. Pod usually much curved and thick, either slender and narrow, or 3 to 4 
lines broad and very thick. — Mimosa Sophone, Labill. PI. Nov. Holl. ii. 87, t. 237 ; A. Soph one.

Yar. typiea, Benth. FI. Austr. Phyllodia linear-oblong or oblong-lanceolate, mostly obtuse, 
4 to 5in. long, coriaceous but often less so than in the last, the reticulate veinlets more or less 
elongated and parallel. Pod usually long and slender.— Mimosa longifolia, Andr. Bot. Rep. t.

Var. floribunda, F. v. M. PI. Viet. ii. 31. Phyllodia linear or linear-lanceolate, usually nar- 
rowed at each end or acute, 3 to 5in. long, less coriaceous than some other forms, the smaller 
veins less anastomosing and passing into long parallel veins scarcely finer than the principal 
nerve. — A. angustifolia, Lodd. Bot. Cab. t. 763. — About Stanthorpe. 
81. A. linearis (linear-leaved), Sims, Bot. Mag. L 2156 ; Benth. FI. Austr. 
ii. 400. An erect shrub of several feet, glabrous or slightly pubescent when 
young ; branchlets angular. Phyllodia narrow-linear, from 4, 5, or Gin. long to 
twice that length, scarcely above 1 line broad, yvith a prominent longitudinal 
nerve and occasionally an additional faint one on each side. Spikes loose and 
interrupted, slender, 1 to 2in. long, quite glabrous. Flowers mostly 4-merous. 
Calyx very short, toothed. Petals smooth, united at the base. Pod linear, 
nearly straight, several inches long, usually about 2 lines broad. Seeds longi-
