Mysore thorn, Wait-a-while, Wait-a-bit, Wait a while, Wait a bit, Mauritius thorn, Shoofly, Thorny poinciana, Tiger stopper, Whoa back, Whoa-back, Woody wait-a-while.
A large sprawling shrub (2-4 m tall) or tall climber with prickly branches. These branches are also densely covered with tiny brownish or golden-coloured hairs. Its twice-compound leaves have a prickly main stalk and 4-10 pairs of branchlets. Its pale yellow flowers have five petals (10-15 mm long) and are borne in elongated clusters (10-40 cm long) at the tips of the branches. Its brown, flattened, pods (6-10 cm long and about 25 mm wide) have a small projection at their t
Impact
Impact
Mysore thorn (Caesalpinia decapetala) is regarded as an environmental weed in New South Wales and Queensland, and is particularly troublesome in the wetter parts of south-eastern Queensland and north-eastern New South Wales. It is an extremely aggressive climbing plant that smothers native vegetation and makes walking though infested areas impossible. It forms stands along roadsides and creeks (i.e. in riparian zones) and invades disturbed tropical and sub-tropical rainforests. This species dominate native vegetation and severely impact biodiversity through restricting germination, reducing forest biomass and by smothering native species. It also restricts the movement of native fauna and the sprawling thickets provide habitat for foxes and other pest animals.In Hawaii, Mysore thorn (Caesalpinia decapetala ) is also seen as a formidable threat to native forests. It is another species that is listed in the Global Invasive Species Database.
