49. A. Simsii (after Dr. J. Sims), A. Cunn .; Benth. in Hook. Bond. Journ. 
i. 368, and FI. Anstr. ii. 382 ; F. v. M. Ic. Dec. vii. 10. A tall glabrous shrub 
with slender branches scarcely angular. Phyllodia linear or lanceolate, usually 
falcate, obtuse or mucronate, much narrowed towards the base, 2 to 5in. long, 
to 2 or rarely 3 lines broad, in the ordinary form with 3 or sometimes only 2 
prominent nerves, smooth and finely veined between them. Peduncles solitary or 
in pairs, slender, rarely above 3 lines long, bearing each a globular head of 20 to 
30 flowers, mostly G-merous. Calyx nearly half as long as the corolla, lobed, 
and readily separating into distinct sepals. Petals smooth, distinct. Pod straight, 
flat or undulate, acuminate, 2 to 3 lines broad. Seeds compressed-globular, 
longitudinal ; funicle with the last fold shortly thickened into a clavate aril about 
half as long as the seed, with a short filiform fold below it. 
Hab.: Islands of the Gulf of Carpentaria, R. Brown, Henne ; Bay of Inlets, Banks and 
Solander ; rocky hills, Cleveland Bay, A. Cunningham; Cape Upstart, Burdekin Expedition; 
Port Denison, Fitzalan ; Edgecombe Bay, Dallachy ; bed of the Belyando, Mitchell; also in 
Leichhardt’s collection. 
Var. multisiliqua. Phyllodia shorter, rather broader, and nearly straight, with 3 prominent 
nerves and scarcely veined between them. Pod narrow. — On first seeing B. Brown’s specimens 
from the Carpentaria Islands, they looked so different from the ordinary form that I was inclined 
to adopt them as a distinct species under Brown’s name of A. multisiliqua, but I have since found 
that the two forms pass one into the other there as in other localities, and both phyllodia may be 
found even on the same specimen on different branches, depending perhaps sometimes on 
differences in comparative luxuriance. — Benth. 
50. A. homalophylla (smooth-leaved), A. Cunn.; Benth. in Hook. Lond. Journ. 
i. 365 (there spelt omalopliylla), and FI. Austr. ii. 383 ; F. v. M. Ic. Dec. vi. 7. 
Gidgee. “Wong-arrah,” Cloncurry, Palmer. A small tree, glabrous or the foliage 
minutely hoary or pale ; branchlets at first slightly angular. Phyllodia lanceolate- 
falcate, narrow -oblong or linear, obtuse with a small oblique point, narrowed at 
the base, 1 to 3in. long, 1 to 4 lines broad, thick, very finely striate with parallel 
nerves only to be seen under a lens. Peduncles in pairs or clustered on a very 
short common peduncle, bearing dense globular heads of numerous flowers, 
mostly 5-merous. Sepals cuneate or spathulate, free or slightly connate, more 
than half as long as the corolla. Petals smooth, free. Pod linear, usually 
glaucous, slightly curved, 2 to 3 lines broad, longitudinally veined ; valves 
coriaceous, convex over the seeds, contracted between them. Seeds oval-oblong, 
longitudinal ; funicle short, much folded and dilated almost from the base into a 
short oblique aril. — F. v. M. PI. Viet. ii. 28. 
Hab.: Inland localities. 
Gum eaten ; the wood used for boomerangs, also the favourite wood for spears, on the 
Cloncurry. — Palmer. 
Wood dark, close-grained, prettily marked, hard, heavy. — Bailey's Cat. Ql. Hoods No. I33a. 
51. A. georginae (found on Georgina River), Bail.Bot. Bull. xiii. Georgina 
Gidgee. A large shrub or small tree, with dense spreading head. Has a strong 
disagreeable scent. Branches and trunk usually very crooked, bark thick and 
rough ; young branchlets flattened or triangular, and like the foliage all more or 
less clothed with a hoary tomentum. Phyllodia lanceolate-falcate, 2£ to 3iin. 
long, 3 to 4 lines broad, much narrowed towards the base, and bearing at the 
apex a small thickened oblique point ; texture thick, hard and brittle ; the 
parallel nerves 2, 3 or 4, but like the finer veins often very obscure from the thick 
substance of the phyllodia. Flowers not available. Pod falcate or curved into a 
circle, very obtuse at each end ; thin, flat, wavy, and elegantly marked with 
branched reticulate veins, 2 or 3in. long, fin. broad. Seeds few, distant, 
transverse, very flat, about 5 lines broad, surrounded by a narrow wing-like 
border, glossy-brown, funicle thickened into a narrow clavate aril, below which 
are 1 or 2 folds.
