5. A. canescens (hoary), Benth. FI. Austr. ii. 423 ; F. v. M. Ic. Dec. xiii. 1. 
“ Thow-i-ee,” Mackay, Macartney. A beautiful spreading tree, the young shoots 
silky-pubescent, the adult foliage more or less hoary with a very minute appressed 
pubescence. Pinnae usually 2 pairs, rarely with a fifth odd pinna or a third pair, 
the common petiole 2 to 4in. long, each rhachis 3 to 6in.; leaflets 5 to 8 pairs on 
the terminal pinnae, very obliquely obovate and unequally narrowed at the base, 
mostly f to ljin. long, fewer and smaller on the lower pinnae, penniveined but 
the veins much less prominent than in A. Lebbeck. Flower-heads small, 
numerous, on short peduncles in dense terminal panicles much shorter than the 
last leaves. Flowers sessile, mostly 5-merous. Calyx about 1 line, corolla about 
2| lines long, both silky-pubescent. Stamens about Jin. long, the united part 
shorter than the corolla. Pod stipitate, often 8 to lOin. long and 1J to 2Jin. 
broad in our specimens, very thin and flat. Seeds flat, orbicular, along the centre 
of the pod. 
Hab.: Burdekin River, F. v. Mueller; Fitzroy and Bowen Rivers, Boicman; Rockhampton, 
Thozet, Dallacliy. 
Allied on the one hand to A. procera, on the ofcher to A. Lebbeck, differing from the former in 
the broader flowers, much longer stamens, the panicle more dense, and a much broader pod ; 
from A. Lebbeck in the much smaller closely sessile flowers and broader pod, and from both in 
the general aspect of the foliage. — Benth. 
Wood of a dark colour, resembling Walnut, nicely marked ; suitable for cabinet-work. — Bailey's 
Cat. Ql. Woods No. 148. 
94. PITHECOLOBIUM, Mart. 
(From the Greek — monkey-pod.) 
(Cathormion, Hassk.) 
Calyx campanulate or tubular. Corolla 5-lobed, with a cylindrical tube. 
Stamens indefinite, usually numerous and long, united at the base in a tube 
enclosing the ovary. Pod flattened, usually rather thick and much curved, 
annular or spirally twisted, either opening entirely or on the outer edge in 
2 valves, or quite indehiscent, very smooth and often coloured inside or with a 
thin pulp. Seeds ovate or orbicular ; funicle filiform. — Trees or rarely shrubs, 
without prickles. Leaves twice pinnate, usually with a gland on the petiole below 
the pinnee, and others between or below some or all of the pinme and leaflets ; 
leaflets few and rather large in all the Australian species. Flowers in globular 
or oblong heads or umbels, or rarely in cylindrical spikes, usually hermaphrodite 
and white, the stamens rarely red. 
A considerable tropical genus, distributed over the New as well as the Old World. Of the 
Australian species, one is also in the Indian Archipelago, the others are endemic. 
Pithecolobium, with the flowers and fruit of some sections of Inga, only differs from that 
genus in the twice-pinnate, not simply pinnate, leaves. Calliandra and Albizzia have the same 
flowers and only differ in the pod. Acacia is at once and constantly distinguished by the 
stamens never united in a tube round the ovary. — Benth. 
Flowers pedicellate in the head (umbellate). 
Leaflets oblong or rhomboidal, acuminate. Pod twisted, 2-valved ... 1. P. pruinosum. 
Leaflets obliquely obovate, obtuse. Pod indehiscent, very hard, separating 
into distinct articles 2. P. moniUferum. 
Flowers sessile, the corolla Jin. long. Leaflets acuminate, glabrous or nearly so 3. P. yrandijlorum.
