#Acacia armata
- Kangaroo thorn — A thorny shrub or small tree species native to Australia, officially recognized in modern taxonomy under the accepted name 'Acacia paradoxa', but frequently referenced in historical and horticultural literature by its synonym 'Acacia armata'. The plant is distinguished by a dense canopy, angular branches covered with sharp stipular spines, and asymmetric, wavy phyllodes that give it an impenetrable appearance; for this reason, it was historically used to create defensive hedges, while also being valued for its bright yellow globular inflorescences.
