XLIII. LEGUMINOS-55. 
[Acacia. 
Petals smooth, readily separating. Pod linear, usually curved, to 2 lines 
broad, contracted between the seeds. Seeds ovate, longitudinal ; funicle thickened 
into a lateral oblong or club-shaped aril, with a short fold below it. — A. Nemstii, 
F. v. M. Fragm. iv. 3. 
Hab.: Brisbane River, Moreton Bay, A. Cunningham, C. Stuart, Ncrnst ; towards Mount 
Pluto, Mitchell; between Suttor River and Peak Range, F. v. Mueller. 
46. A. translucens (bright), A. Cunn. in Hook. lc. PI. t. 160 ; Bentli. FI. 
Austr. ii. 379. A bush shrub or small tree, glabrous or the young shoots 
pubescent ; brancblets terete or slightly angular. Phyllodia from obliquely 
obovate to narrow-oblong or almost linear, incurved, usually much undulate, 
mostly about Ain. but the lower ones sometimes lin. long, obtuse with an oblique 
or recurved terminal gland, coriaceous, obscurely several-nerved. Peduncles rigid, 
£ to lin. long, bearing each a dense globular head of numerous flowers, mostly 
5-merous. Calyx broad, cup-shaped, shortly toothed, scarcely half as long as the 
corolla. Petals striate, but smaller and less rigid than in A. impressa. Pod 1 to 
ljin. long, flat but thick, and almost woody, obtusely hooked at the end, about 
2 lines broad above the middle and gradually narrowed into a long stipes, 
obliquely veined, partitioned inside between the seeds. Seeds oblong, oblique ; 
funicle slightly folded and gradually dilated into a cup-shaped aril at the base of 
the seed. 
Hab.: Islands of the Gulf of Carpentaria, B. Brown. 
The pod is that of some Julijiorte, but has only been seen in the narrow-leaved speci- 
mens. — Bentli. 
47. A. impressa (referring to depression on seed). F. v. M. in Journ. Linn. 
Soc. iii. 133; Bentli. FI. Austr. ii. 380. A tall shrub, the branches slightly 
angular, more or less pubescent as well as the foliage. Phyllodia obovate or 
obovate-oblong, very oblique, undulate, obtuse or with a small glandular point, 
^ to f or rarely lin. long, with 3 to 5 nerves more prominent than in 
A. translucens, and anastomosing veins. Peduncles about as long as the 
phyllodia, bearing each a globular head of about 12 to 20 flowers, mostly 
5-merous. Sepals distinct or slightly coherent, spathulate. Petals rigid and 
striate, united at the base. Pod straight or nearly so, thinly coriaceous, flat with 
thickened margins, about Ain. broad, very glutinous and villous. Seeds oval- 
oblong, transverse, the central area much depressed ; funicle forming several 
folds, the last 2 or 3 dilated into a rather small aril at the base of the seed. 
Hab.: Northern interior. 
Very near A. translucens in foliage and flowers, but with a very different fruit. — Bentli. 
48. A. elongata (lengthened), Sieb. in DC. Prod. ii. 451 ; Bentli. FI. Austr. 
ii. 381. A tall shrub, glabrous, or the young shoots silky-pubescent. Phyllodia 
narrow-linear, obtuse, or with a small oblique or hooked point, 2 to 3 or even 4in. 
long, 1 to 1A or rarely above 2 lines broad, with 3 prominent nerves, and when 
broad, a few oblique veins between them. Peduncles solitary or in pairs, not 
exceeding Ain. and usually much shorter, slender and pubescent, bearing a globular 
head of numerous (30 or more) flowers, mostly 5-merous. Calyx obtusely lobed, 
fully half as long as the corolla. Petals smooth, with the midrib slightly pro- 
minent. Pod linear, straight, flat, 1A to 2 lines broad. Seeds longitudinal, the 
last folds of the short funicle dilated into a small aril at the base of the seed. — 
Bot. Mag. t. 3337 ; F. v. M. PI. Viet. ii. 24 ; A. hebecephala , A. Cunn. in Lond. 
Hort. Brit. 406. 
Hab.: Southern Queensland, Rev. B. Scortechini. 
This species differs from A. trinervata chiefly in the long narrow phyllodia, not pungent, when 
very narrow they are almost like those of the Calamiformes. In some garden specimens the 
nerves almost disappear as represented in the above quoted figure ; and then it is not very easy 
to distinguish them from those specimens of A. viscidula in which the nerves are very faint. —
