Acacia paradoxa
Kangaroo thorn
The kangaroo thorn, even kangaroo acacia ( Acacia paradoxa; synonym Acacia armata ) is a plant of the genus Acacia (Acacia ). The Kangaroo Thorn is located in Australia.
Description
The kangaroo thorn is a woody plant; it grows as an upright shrub with a more efficient ring growth and reaches heights of growth 1-4 meters. The brownish- gray bark is finely fissured, more or less hairy branches are grooved cylindrical and flat.
The thorny expiring, slender stipules are about 5 to 15 millimeters long. The function of the leaves take on so-called phyllodes, so flattened petioles. They are 0.8 to 3 inches long and 2.5 to 7 mm wide, lanceolate to narrowly elliptic bent out of shape and just to weak. You are bald to hairy and midrib as the ribs on the edge protrude significantly, however, the side ribs remain unclear. The leaf margins are often more or less wavy, the blade tip is pungent pointed. Near the outer leaves and there is a small gland, as well as an up to 0.5 mm long pulvinus.
Flowering period July to November. From the axils rarely develop to two inflorescences. The most hairless flower stems are 6 to 20 millimeters long, the actual buds are spherical heads out around 20 to 45 flowers. These have a diameter of 5 to 10 millimeters and are colored yellow to light yellow. The legumes are more or less straight, densely hairy, 2-7 cm long and 3-5 mm wide. The seeds are oblong, occasionally the funiculus filiform.
Dissemination
The kangaroo thorn is native wild in Australia in the states of Queensland, Victoria, Western Australia and South Australia, from culture and he is now naturalized in Tasmania.
