8. A. pugioniformis (dagger form), Wencll. Comm. Arar. 38, t. 9, hut not the 
syn. given in Flora, 1819, 139 ; Benth. FI. Austr. ii. 338. A tall glabrous shrub, 
with slender slightly angular branches. Phyllodia rather numerous, straight or 
slightly curved, mostly erect, linear-subulate, 1J to 2 or rarely 3in. long, 
abruptly terminating in a short straight point, nearly tetragonous by a prominent 
nerve on each side. Stipules minute. Peduncles solitary or 2 together, 2 to 3 
lines or rarely Jin. long, bearing each a globular head of numerous flowers, 
mostly 5-merous. Sepals linear-spathulate, ciliate, at length free, about half as 
long as the corolla. Petals smooth, with a prominent midrib. Pod unknown — 
DC. Prod. ii. 450 ; A. quaclrilateralis, DC. Prod. ii. 451. 
Hab.: Brisbane and Logan Rivers, A. Cunningham ; also in Leichhardt's collection. 
The A. quadrilateralis inserted by Decaisne in the Herb. Tim. Deser. 132 as a Timor plant, 
which I have not seen, is more likely to be the following species. — Benth. . 
9. A. juncifolia (Rush-leaved), Benth. in Hook. Bond. Journ. i. 341, and 
FI. Austr. ii. 839 ; F. r. M. lc. Dec. ii. A tall glabrous shrub, with slender 
branches, quite terete. Phyllodia linear-subulate, erect or spreading, slightly 
flattened with a scarcely prominent nerve on each side, 3 to Bin. long or even 
more, with a very short erect or curved point or obtuse. Stipules minute. 
Peduncles solitary or 2 together, rarely Jin. long, bearing each a small globular 
head of numerous flowers, mostly 5-merous. Sepals spathulate, at length free, 
half as long as the corolla. Petals smooth, without the prominent midrib of A. 
pugioniformis. Pod straight, flat or flexuous, often 3 or 4in. long, 1J to 2 lines 
wide. Seeds obovate-oblong, longitudinal ; funicle not folded, slightly thickened 
towards the end. — A. pinifolia, Benth. in Mitch. Trop. Austr. 342. 
Hab.: Islands of the Gulf of Carpentaria, E. coast, R. Brown ; Port Bowen, A. Cunningham ; 
near Mount Pluto, Mitchell ; also in Leichhardt’s collection. 
Var. planifolia. Phyllodia flatter, nearly a line broad, with a more prominent midrib, almost 
like those of A. subulata, but the peduncles all simple. — In Mitchell’s collection (Benth.) 
10. A. calamifolia (cane-like), Sweet, in Hindi. Bot. Beg. t. 839 ; Benth. 
FI. Austr. ii. 339. A tall shrub, glabrous and often glaucous or slightly mealy, 
the branches rather slender and terete. Phyllodia linear-subulate, in the 
northern specimens very slender and mostly 3 to 4in. long, in the more southern 
ones usually about 2in., and from that to 3in. rarely shorter, and then often 
slightly flattened and nearly 1 line broad but thick, sometimes slender as in the 
long ones, always tapering into a fine recurved point which only wears away with 
age, nerveless or with one fine nerve on each side. Flower-heads globular, 
smaller than in A. pugioniformis, and usually 3 or 4 in a short raceme, more 
rarely solitary. Flowers numerous, mostly 5-merous. Calyx thin and trans- 
parent, with short, broad, ciliate lobes, often splitting into spathulate sepals. 
Petals smooth, distinct. Pod often 5 or 6in. long, usually curved, 2 to 2J lines 
broad, but much contracted between the distant seeds, the valves hard and convex 
over the seeds. Seeds oblong, longitudinal ; funicle long, often almost encircling 
the seed, then bent back and returning within the previous fold, thickened at the 
end into a long clavate or shortly turbinate fleshy aril. — Lodd. Bot. Cab. t. 909 ; 
F. v. M. PI. Viet. ii. 12 ; A. pulverul'enta, A. Cunn.; Benth. in Hook. Lond. 
Journ. i. 312 (the shorter-leaved southern specimens). 
Hab.: Stanthorpe. 
11. A. lycopodifolia (Club Moss-leaved), A. Cunn. in Ilook. Jr. PI. t. 172; 
Benth. FI. Austr. ii. 343. A much-branched diffuse or divaricate shrub, clothed 
with very short spreading hairs and more or less viscid. Phyllodia verticillate, 
about 8 to 10 in the whorl, subulate, rarely above 3 lines long and often only 1 to 
2 lines, sulcate with a prominent vein on each side, erect at the base, recurved at 
the end with a fine glabrous viscid point, sometimes very short, sometimes nearly
