'''''Acacia paradoxa'''''<ref name=APNI>{{cite web |url=http://www.anbg.gov.au/cgi-bin/apni?TAXON_NAME=ACACIA+PARADOXA|title=''Acacia paradoxa'' |accessdate=2008-04-03|work= [[Australian Plant Name Index]] (APNI), IBIS database|publisher = Centre for Plant Biodiversity Research, Australian Government, Canberra}}</ref>  is a plant in the [[Fabaceae]] family. Its common names include '''kangaroo thorn''', '''prickly wattle''', and '''paradox acacia'''. This is a large [[shrub]] up to 3 meters tall and wide. It is dense with foliage; the leaves are actually enlarged [[petiole (botany)|petioles]] known as phyllodes. They are crinkly and the new ones are covered in hairs. The bush is also full of long spines. It flowers in small, bright yellow spherical flower heads and the fruits are brown pods 4 to 7 centimeters long.

The spiny 'stipulles' which grow at the base of the phyllodes deter livestock from feeding on or too close to the plant.

Kangaroo thorn is widely spread across Australia, regenerating from seed after disturbances, such as bush fire. Small birds, including wrens, use this plant as shelter and dwelling, while it is relied upon as a food source for moths, butterfiles and other insects, and birds feed on its seeds.

This plant is native to Australia, but has been introduced to other continents. In the United States, kangaroo thorn is a well-known [[noxious weed]] in California.

Acacia armata, R. Br. (A. undulata, Willd. A. paradoxa, DC. A. furcifera, Lindl. Mimosa paradoxa, Poir.). Kangaroo Thorn. Fig. 71. A spreading shrub 8-10 ft. wide, 7-11 ft. tall, with pendent finger-like branchlets: phyll. half-ovate, the straight edge hugging the st., the other edge more or less undulate; nerve excentric, ending in a pungent point; stipules reduced to slender spines about 1/4in. in length: fls. solitary on peduncles 3/4in. long; petals 5; sepals 5, more than one-half length of corolla: pods hairy, straight or slightly curled, in clusters of 2-5 or reduced to 1, l 1/2-2 in. long, 3/16in. wide; funicle silvery, as long as seed and enlarged to a cup-shaped aril; ripe Aug. Fls. Feb.-Apr.— A shrub with breadth often much greater than its height, sometimes 15-20 ft. across, hence suitable for large grounds and roomy corners. Makes a good hedge plant, and is also used to reclaim sand-dunes. It is a good rich green and withstands considerable dust and drought. There is a larger-lvd. form with fissured bark and more straggling habit. The phyll. is greener and more tender in texture than the type, and the fls. are larger.
