But, I for one, adore this tree for its spikes of yellow flowers. When the tree is covered with countless inflorescences, the sight is especially spectacular. Well, at least to me.
The curved, leaf-like structures are not the true leaves, but are in fact phyllodes, or modified leaf stalks, which serve the same function of leaves for photosynthesis. The slightly crescent-shaped phyllodes gave rise to its specific epithet auriculiformis or in simple English auricle due to its vague resemblance to a ear. Hence, the common names are also known as Earleaf Acacia, Earpod Wattle. The other common names include Auri, Black Wattle, Northern Black Wattle etc.
These photos were taken beside the Pasir Panjang substation inside HortPark. Within a couple of years, I am sure this weed would be huge enough to soften the substation building.
