42. A. cultriformis (the leaves formed like a kind of knife), A. Cunn. in G. 
Don , Gen. Syst. ii. 406 ; Benth. FI. Auxtr. ii. 875. A tall bushy shrub, glabrous 
and often mealy glaucous when young ; branchlets angular. Phyllodia numerous, 
obliquely obovate-lanceolate, recurved-falcate or almost triangular, mucronulate, 
narrowed at the base, \ to fin. or rarely lin. long, coriaceous, 1-nerved, with 
thickened margins and usually 1 marginal gland, sometimes on a prominent 
angle. Racemes numerous, much longer than the phyllodia, consisting often of 
10 to 20 globular heads, forming a terminal leafy panicle. Flowers 10 to 20 in 
the head, mostly 5-merous. Calyx broad, lobed, scarcely half as long as the 
corolla. Petals smooth. Pod very flat, glabrous, glaucous, 2 to 3in. long and 3 
to 4 lines broad. Seeds longitudinal near the suture ; last fold of the funicle 
thickened into a lateral club-shaped aril, with very small folds below it. — Hook. 
Ic. PL t. 170; Paxt. Mag. xi. 113, with a fig.; A. scapuliformis, A. Cunn. in G.

43. A. myrtifolia (myrtle-leaved), Willd. Spec. PI. iv. 1054; Benth. FI. 
Auxtr. ii. 376. A tall glabrous shrub, slightly glaucous in some varieties ; 
branches acutely angular. Phyllodia oblique or falcate, obovate, ovate-lanceolate, 
lanceolate or linear, usually acute or mucronate and narrowed at the base, 1 to 
2in. long or much longer when narrow, coriaceous, 1-nerved, with thickened 
nerve-like margins, the pinnate veins rarely conspicuous, the marginal gland 
below the middle. Racemes rarely exceeding the phyllodia, with several almost 
sessile flower-heads, consisting of only 2, 3 or 4 rather large flowers, almost 
always 4-merous. Calyx very short, broadly lobed. Petals smooth, separating 
nearly to the base. Pod linear, curved, flattened, but thick, with very thick 
margins, usually 1 to 2in. long, about 2 lines broad ; valves hard and almost 
woody. Seeds oblong, longitudinal ; funicle very short, scarcely folded, thickened 
nearly from the base into an almost cup- shaped fleshy aril. — Mimosa myrtifolia ,

44. A. sublanata (somewhat woolly), Benth. in Huey. Emm. 42, and FI. 
Austr. ii. 378. A rigid shrub, woolly-pubescent when young, at length glabrous; 
branches striate. Phyllodia from broadly triangular-falcate and mucronate to 
lanceolate-falcate and tapering into a pungent point, rarely ^-in. long, without any 
or with a very minute gland, and always with 8 to 5 or even more nerves. 
Stipules small, deciduous. Peduncles longer than the phyllodia, bearing each 
a globular head of 20 to 30 flowers, mostly 5-merous, glabrous or slightly 
hirsute, the bract-points projecting beyond the young buds. Calyx shortly 
toothed, half as long as the corolla. Pod linear, much twisted, about 2 lines 
broad. — A. pravifolia, F. v. M. Fragm. i. 4, and in Journ. Linn. Soc. iii. 117.

45. A. amblygona (obtuse-angled), A. Cunn.: Benth. in Hook. Loud. 
Journ. i. 332, and FI. Austr. ii. 378 ; F. v. M. Ic. Dec. vii. 3. Branches 
elongated, diffuse, rather rigid, terete, pubescent. Phyllodia falcate-lanceolate or 
almost triangular, 3 to 4 lines long, 14- to 3 lines broad, several-nerved, the lower 
nerve produced into a sharp point, the upper margin much curved but without 
any glandular angle. Peduncles rarely exceeding the phyllodia, bearing each a 
globular head of about 10 to 15 flowers, mostly 5-merous. Sepals broadly 
cuneate, cohering or at length separating, fully half as long as the corolla.
