128. A. Sutherlandi (after J. Sutherland), F. r. M., Tc. Dec. xii. 8. 
(. Albizzia Sutherlandi, F. v. M. Fragm. vi. 22, ix. 179 ; Acacia melaleucoides, 
Bail., Proc. Roy. Soc. Ql. v. 121.) A small tree, the bark on the trunk much 
cracked and of a dark colour, the branches drooping, branchlets more or less 
angular and corky, young growth said to be of a decided golden hue. Leaves 
slender, 6 to over 12in. long, of from 15 to over 20 pairs of pinnae 2 to 3in. long; 
common petiole 2 to 3in. long ; leaflets linear, 2 to 2J lines long and about \ line 
broad ; glands dark, between the 3 upper pairs of pinnae only. Stipules none on 
the specimens examined. Peduncles solitary, about lin. long, bearing a stem- 
clasping 2-lobed bract about the middle. Spike about liin. long. Flowers 
numerous but not crowded, pale-coloured, bracts subtending the flowers very 
deciduous, narrow. Calyx-tube nearly 2 lines long, teeth 3, rather broad and 
silky. Corolla-tube about 2 lines long, teeth 5, about i- line long, narrow silky. 
Stamens numerous, exserted about 3 lines ; anther minute, globular. Pod very 
thick, 4 to Gin. long, fin. wide, sessile. Seeds thick, oval, about 5 lines long. 
Hab.: Southern slope of Newcastle Range, between Georgetown and Junction Creek. — 
It. C. Burton. 
It was after publishing this plant as Acacia melaleucoides that I found that Baron Mueller had 
published it some years previously as Albizzia Sutherlandi; he, however, removed it into the 
genus Acacia about the time my name was published. I think, however, under the circumstances 
his name should stand. 
93. ALBIZZIA, Durazz. 
(After the noble family of Albizzi.) 
Calyx campanulate or tubular, 5 or rarely 4-toothed. Corolla 5 or rarely 
4-lobed, with a cylindrical tube. Stamens indefinite, usually numerous and long, 
united at the base in a tube enclosing the ovary. Pod linear or oblong, straight 
or nearly so, flat, thin, rarely coriaceous, indehiscent or opening without elasticity 
in 2 valves. Seeds usually orbicular, along the centre of the pod ; funicle fili- 
form. — Trees or shrubs, without prickles. Leaves twice pinnate, with a gland on 
the petiole below the pinnfe and others between or below some or all of the pinna? 
and leaflets. Flowers in globular heads or rarely cylindrical spikes, usually 
hermaphrodite. Stamens white or pink, rarely yellow, much longer than in 
Acacia. 
The genus is limited to the Old World, and is chiefly tropical. Of the following species, one is 
widely dispersed over tropical Asia, the others are endemic. F. v. Mueller proposes to reunite this 
and Pithecolobium with Acacia, but that can scarcely be done without returning to the Linnsean 
genus Mimosa, for Pithecolobium as to flower and fruit, and Albizzia as to flowers, are undis- 
tinguishable from Inga, whilst Lysiloma as closely connects Acacia with Mimosa. If the Linnsean 
Mimosa is broken up into distinct genera, there is no character so constant and so easily recog- 
nised as that which separates Acacia from Albizzia. It is, however, very difficult to draw a 
definite line between Albizzia and Pithecolobium, which only differ in the fruit. — Bentli.

A. Lebbeck, Benth., allied to A. canescens, but more glabrous, with much larger flowers, not 
closely sessile, and the pod not so broad, &c., a tree widely dispersed over tropical Asia and 
Africa, has been introduced into the neighbourhood of Brisbane. — Benth. Planted near settle-
