Hab.: North Coast Bailway Line, near Eumundi. 
Enumerated by F. v. Mueller amongst tbe varieties of A. longifolia, and certainly very near 
the extreme forms of the var. dissitiflora, differing chiefly in the long narrow phyllodia, either 
strictly 1-nerved or with only a faint accessory nerve on each side. — Benth. 
82. A. cyperophylla (sedge-leaved), F. v. M. Herb.; Benth. FI. Austr. ii. 
400; F. v. M. Ic. Dec. x. 6. Tall, with curly bark and dark wood, branchlets terete. 
Phyllodia linear-subulate, with a fine usually curved point, 6 to lOin. long, terete 
or very slightly compressed, striate with numerous exceedingly fine parallel nerves 
only visible under a lens, hoary with a very minute loose pubescence. Spikes 
sessile or nearly so, oblong, not Jin. long. Flowers mostly 5-merous or 6-merous. 
Calyx turbinate, about half as long as the corolla, at first shortly toothed but 
often dividing nearly to the base. Petals smooth, glabrous. Pod straight, very 
narrow, about 8 Jin. long. Seeds oval, very obliquely placed in the pod ; funicle 
much folded, forming an aril at the end. 
Hab.: Southern inland localities. 
83. A. pityoides (Pine-like), F. v. M. in Journ. Linn. Soc. iii. 135 ; Bentli. 
FI. Austr. ii. 400; F. v. M. 1c. Dec. x. 7. Quite glabrous; branchlets slender, 
terete. Phyllodia linear-subulate, rather rigid but not pungent, 2 to 4in. long, 
slender, terete and almost nerveless, or slightly flattened and striate with very 
fine nerves, scarcely visible without a lens. Spikes usually in pairs, pedunculate, 
about Jin. long, slender but dense. Flowers small, mostly 5-merous. Calyx 
very thin and transparent, deeply lobed or the sepals quite free but not spathulate, 
fully two-thirds as long as the corolla. Petals thin, connate to the middle, with- 
out prominent midribs. Pod elongated, nearly flat, curved or twisted, 1 to 1J 
lines broad, slightly contracted between the seeds ; valves thinly coriaceous. Seeds 
obovate, longitudinal ; funicle straight, enlarging upwards. 
Hab.: Ridges of the Suttor, F. v. Mueller. 
84. A. aneura (wanting nerves) F. v. M. in Linncea, xxvi. 627, and Fragm. 
iv. 8 ; Benth FI. Austr. ii. 402 ; F. v. M. Ic. Dec. x. 8. Mulga. Shrub or tree, often 
hoary with a very minute pubescence ; branchlets terete or nearly so. Phyllodia 
narrow-linear, obtuse or with a recurved or oblique callous point, usually flat but 
thick, 1J to 3in. long, 1 to 1J line broad, but varying from short and narrow- 
oblong to very narrow and almost terete, without conspicuous nerves, but finely 
and obscurely striate under a lens. Spikes shortly pedunculate, J to fin. long. 
Flowers mostly 5-merous. Sepals very narrow, linear-spathulate. Petals 
smooth. Pod thin, flat, obliquely oblong, very obtuse, narrowed at the base, 1 to 
ljin. long, about 4 lines broad, the sutures edged with a narrow wing. Seeds 
ovate, oblique or transverse ; funicle with 2 or 3 short folds, expanded into a 
small membranous aril under the seed. 
Hab.: Inland localities. 
Foliage largely used as food for stock in times of drought. 
85. A. cibaria (used for food) F. v. M., Melb. Chon., July 1882. A tall 
shrub or small tree ; branchlets not angular, slightly silky. Phyllodia rather 
long, thick, rigid, broadly linear, very finely many-nerved, of greyish hue, curved- 
apiculated ; stipules and gland obliterated. Spikes axillary, solitary, short- 
stalked, not elongated. Flowers slightly short-hairy. Bracts rhomboid towards 
the summit, very thin towards the base, surpassed in length by the flowers. 
Sepals narrow, free, hardly half as long as the unstreaked corolla. Pods straight,
