22. A. sentis (prickly), F. r. 21. in Journ. Linn. Soc. iii. 128, and PI. Viet. 
ii. 18 ; Bentli. FI. Austr. ii. 3G0 ; F. v. M. Ic. Dec. iv. 9. “ Gundey bluey,” St. 
George, “ Narran,” St. George, Wedd. A divaricately-branched rigid shrub or 
small tree, branchlets nearly terete, glabrous or pubescent when young. 
Phyllodia lanceolate-oblong or linear, mostly oblique falcate or curved, 1 -nerved 
and more or less penniveined, in some specimens fin. long and 2 or 3 lines broad, 
in others more than 2in. long and about 1 line broad, usually glabrous, the 
marginal gland near the base or none. Stipules either subulate-spinescent or 
very small or none. Peduncles rather slender, solitary or in pairs, axillary or by 
the abortion of the phyllodia in terminal racemes, bearing each a small globular 
head of 20 to 30 flowers, mostly 5-merous. Sepals linear-spathulate, free. 
Petals smooth. Pod thin, flat, h to fin. broad. Seeds broadly ovate, longi- 
tudinal, along the centre of the pod ; funiele transverse, gradually thickened from 
the base upwards, straight or shortly folded under the seed.— A. Victoria , Benth. 
in Mitch. Trop. Austr. 333. 
Hab.: Gulf of Carpentaria, F. v. Mueller ; Barcoo River, Mitchell. 
Wood close-grained, hard, and nicely marked. — Bailey’s Cat Ql. Woods No. 128b. 
23. A. fasciculifera (fascicle-bearing), F. v. 21. Herb.; Benth. FI. Austr. 
ii. 361 ; F. v. M. Ic. Dec. iv. 10. A tree, glabrous in all its parts ; branchlets 
slightly angular. Phyllodia lanceolate-falcate, acuminate, with a callous point, 
narrowed at the base, mostly 4 to 6in. long, coriaceous, with a prominent midrib 
and nerve-like margins, the pinnate veins scarcely prominent. Peduncles fili- 
form, ^ to lin. long or even more, clustered in the axils, bearing each a globular 
head of 20 to 30 or more flowers, mostly 5-merous. Sepals narrow, linear- 
spathulate, free. Petals smooth, soon separating. Pod 6in. long and nearly 
fin. broad. Seeds longitudinal, nearly orbicular. 
Hab.: Rockhampton and More ton Bay, Dallacliy. 
The phyllodia are nearly those of A.falcata, but rather more coriaceous, the inflorescence is 
very different, showing an affinity to A. harpophylla and A. complanata. — Benth. 
Wood of a red colour, very hard, close in grain ; a useful building wood. — Bailey’s Cat. Ql. 
Woods No. 128a. 
24. A. falcata (boomerang-formed), Willd. Spec. Pl. iv. 1053; Benth. FI. 
Austr. ii. 361. “ Burra,” Nanango, Shirley. A tall shrub or tree, glabrous, with 
angular branchlets. Phyllodia lanceolate-falcate, acuminate, much narrowed 
towards the base, 3 to 6in. long or even more, 1-nerved, obliquely penniveined, 
the margins slightly thickened without any gland or with an obscure one at the 
base. Racemes much shorter than the phyllodia, usually with 10 to 20 small 
globular heads of about 20 small flowers, mostly 5-merous ; peduncles short and 
slender. Sepals free, narrow-spathulate, ciliate. Petals smooth, soon separating. 
Pod flat, with slightly thickened margins, 2 to 3in. long, about 3 lines broad. 
Seeds ovate, longitudinal, close to the margin ; funiele slightly dilated and 
coloured from the base, very long, extending round the seed and bent back on the 
same side, encircling it in a double fold and thickened at the end into a short fleshy 
aril. — 21imosa obliqua, Wendl. Bot. Beob. 57; A. falcata , DC. Prod. ii. 451; 
Wendl. Comm. Acac. 20, t. 14; Lodd. Bot. Cab. t. 1115; A. playiophylla, 
Spreng. Syst. iii. 135. 
Hab : Brisbane River, Moreton Bay, A. Cunningham, Leichhardt, anti others. 
Wood yellow near the outside, the rest light-brown; heavy and tough. Might prove a useful 
cabinet wood. — Bailey’s Cat. Ql. Woods No. 128c. 
25. A. macradenia (large-glanded), Benth. in Mitch. Trop. Austr. 360, and 
FI. Austr. ii. 362 ; F. v. 21. Ic. Dec. v. 7. A sbrub of 10 to 12ft., glabrous, 
with angular branchlets. Phyllodia lanceolate-falcate, rather acute, much 
narrowed towards the base, coriaceous, 1-nerved, with thickened margins and 
often a gland at the base, like those of A. falcata, but usually longer, attaining
