1. A. Peuce (Pine-like), F. v. M. Fragm. iii. 151 ; Bentli. FI. Austr. ii. 328. 
Ironwood. A tree of 15 to 30ft., with the aspect of a pine, quite glabrous and 
somewhat glaucous. Phyllodia rather crowded, not articulate, but very shortly 
decurrent on the stem, subulate-terete, rigid, tapering into pungent points, mostly 
2 to 3in. long or rather more, straight and erect, with few slightly prominent 
nerves. Stipules very minute and deciduous. Flowers . . . Pod undulate, 
very flat, glaucous, several inches long and nearly l^in. broad. Seeds broadly 
ovate, flat, the funicle filiform to the end. 
Hab.: Birdsville, Dr. T. L. Bancroft. 
2. A. triptera (three- winged), Benth. in Hook. LoncL. Journ. i. 325, and FI. 
Austr. ii. 323 ; F. v. M. Ic. Dec. ix. A dense rigid shrub of 3 or 4ft., quite glabrous. 
Phyllodia numerous, lanceolate, recurved-falcate, decurrent on the stem, rigid 
and tapering into a pungent point, ^ to lin. long, striate with several prominent 
nerves, without any marginal gland. Stipules scarcely any. Peduncles short, 
solitary or 2 together, bearing each a cylindrical spike of ^ to fin. Flowers not 
crowded, very small and globular in the bud, mostly 4-merous. Calyx short, 
broad, lobed. Petals membranous and smooth. Pod curved, flexuose, 2 to 2^in. 
long, to 2 lines broad, slightly constricted between the seeds. Seeds longi- 
tudinal ; the funicle forming 2 or 3 folds at the base of the seeds. 
Hab.: Sandstone ridges, Mantuan Downs, Mitchell ; also in Leichhardt's collection. 
3. A. lanigera (woolly), A. Cunn. in Field, N. S. Wales, 345 ; Bentli. FI. 
Austr. ii. 324. A rigid shrub of several feet, the young shoots usually woolly- 
pubescent. Phyllodia linear or lanceolate, rigid, tapering into a pungent point, 
1 to 1| or rarely 2in. long, mostly 2 to 3 lines broad, with several nerves, occa- 
sionally anastomosing or all parallel. Peduncles exceedingly short, solitary, 
2 together or almost clustered, bearing a globular head of about 30 flowers, 
mostly 5-merous. Calyx campanulate, with broad obtuse lobes, not half as long 
as the corolla. Petals smooth, united to the middle. Pod attaining 6 to bin. in 
length, and 4 or even 5 lines in breadth at the seeds, much contracted between 
them ; the valves slightly convex. Seeds longitudinal, last short fold of the 
funicle and the end of the next much thickened, the remainder of the latter and 
the third fold filiform and extending some way round the seed, but not seen 
perfect. — Bot. Mag. t. 2922. 
Hab.: Stanthorpe. 
Var. gracilipes. Peduncles rather longer, although shorter than in A. trinervata. 
A. multinervia, DC. Mem. Leg. 445, Prod. ii. 450, answers, in the short character given, to 
A. lanigera, with the exception of the gland on the upper edge of the phyllodium, which I do not 
find in that or any other allied species known to me.— Benth. 
4. A. phlebocarpa (pods veined), F. v. M. in Journ. Linn. Soc. ii. 119 ; 
Benth. FI. Austr. ii. 325 ; F. v. M. Ic. Dec. vii. 5. A glabrous, somewhat viscid 
shrub of 2 to 5ft.; branches nearly terete. Phyllodia narrow-lanceolate, rigid, 
tapering into a pungent point, 1 to l£in. long, mostly 2 to 3 lines broad, 
narrowed at the base, with several parallel nerves occasionally anastomosing, 1 to 
3 more prominent. Stipules small. Peduncles solitary, attaining £in. when in 
fruit. Flowers 5-merous, but only seen withered. Calyx turbinate, lobed, half 
as long as the corolla. Petals apparently striate. Pod curved, hard, rather flat, 
with much thickened margins and obliquely veined between them, depressed 
between the seeds. Seeds rounded, compressed, oblique ; funicle with the last 2 
or 3 folds much dilated into a cup-shaped apparently 2-lobed aril, enclosing the 
base of the seed. 
Hab.: Gulf of Carpentaria. 
The species appears to be closely allied to A. lanigera. — Bentli.
