tapering at the base to a stipes of 8 lines, margins thick, apex obtuse, veins 
anastomosing longitudinally, but often more or less hidden by the copious flow of 
resinous gum. Seeds obliquely transverse, oval, the central depression rather 
deep, nearly annular and minutely tubercular ; funicle with 2 or 3 folds, thickened 
under the seed into an irregular cup-shaped aril. 
Hab.: Prairie, Torrens Creek, Northern Railway Line, IF. Ii. Chisholm. 
76. A. stipuligera (stipules prominent), F. v. M. in Journ. Linn. Soc. iii. 
144; Bcnth. FI. Austr. ii. 393; F. v. M. Ic. Dec. xi. 3. Softly tomentose or 
pubescent ; branchlets nearly terete. Phyllodia obliquely falcate, oblong or 
lanceolate, shortly narrowed at each end, with a small callous or hooked point, 
1 to 2in. long, 8 to 7 lines broad, coriaceous, with 2, 3, or 4 very prominent 
nerves and nerve-like margins and numerous anastomosing more or less longi- 
tudinal veins, the principal nerves often scabrous with resinous exudations. 
Stipules brown, small, but more conspicuous than in any other Juliflora except 
A.cojispem i. Spikes nearly sessile, solitary or in pairs, 1 to nearly 2in. long, 
dense and tomentose. Flowers mostly 5-merous. Calyx half as long as the 
corolla, thin, with spathulate lobes, readily separating into distinct sepals. 
Petals united to the middle, tomentose. Pod long, linear, slightly twisted, not 
1J line broad, coriaceous, with nerve-like margins. Seeds very obliquely 
placed in the pod ; funicle rather long, enlarging and closely folding upwards. 
Hab.: Gulf country. 
77. A. umbellata (flowers in umbels), A. Cunn.; Benth. in Hook. Lond. 
Journ. i. 378, and FI. Austr. ii. 394. A tall shrub, young shoots slightly hoary 
or silky but soon glabrous ; branchlets nearly terete. Phyllodia from oblong and 
scarcely falcate to obliquely oblong-rhomboidal or broadly falcate, obtuse with a 
broadly callous or glandular tip, 2 to 4in. long, f to 1 Jin. broad, very coriaceous, 
with numerous parallel nerves or veins, 5 to 9 more prominent and some of them 
confluent with the lower margin at the base, the others closely packed, fine and 
rarely anastomosing. Spikes sessile or nearly so, often clustered, rather dense, 
1 to 1 Jin. long. Flowers mostly 5-merous but sometimes 4-merous. Calyx 
pubescent, sinuate-toothed or shortly lobed. Petals with prominent midribs. 
Pod falcate or nearly straight, almost terete, with convex and coriaceous valves. 
Seeds ovate, oblique ; funicle short, dilated into a small aril of 2 or 3 folds 
under the seed. 
Hab.: Islands of the Gulf of Carpentaria, R. Brown. 
78. A. brevifolia (leaves short), Benth. FI. Austr. ii. 395. Glabrous and 
somewhat glaucous, with angular branchlets. Phyllodia obliquely oblong, some- 
what falcate, very obtuse with a small callous point, narrowed at the base, 1J to 
2in. long, J to fin. broad, very coriaceous with several prominent nerves, the 
intermediate veins irregularly reticulate or longitudinal. Spikes short, oblong- 
cylindrical, pedunculate. Flowers mostly 5-merous. Calyx short, sinuate- 
toothed. Petals smooth. Pod flat, thick, almost woody, with oblique veins and 
thickened margins, very obtuse, ljin. long, nearly 4 lines broad, abruptly 
contracted below the middle into a broad stipes. Seeds oblique, but not seen 
ripe. — A. leptophleba (referred by Benth. to A. aulacocarpa), var. brevifolia, F. v. M. 
in Journ. Linn. Soc. iii. 144. 
Hab : Desert of the Suttor, F. v. Mueller. 
79. A. gonoclada (branchlets angled), F. v. M. in Journ. Linn. Soc. iii. 
140 ; Benth. FI. Austr. ii. 396 ; F. v. M. Ic. Dec. xi. 2. Glabrous and glaucous, 
branchlets stout, with 2 or 3 much raised acute angles. Phyllodia lanceolate- 
oblong, slightly falcate, obtuse with oblique glandular tips, obliquely narrowed 
towards the base, 3 to 4in. long, 4 to 8 lines broad, coriaceous, with 2 or 3 more
