Answer 2

Some threatened plant species found in the hills of Tamil Nadu include the Neelakurinji flower (Strobilanthes kunthiana), Nilgiri tahr grass (Cymbopogon flexuosus), and the Coimbatore memories shrub (Gastrochilus inconspicuus). These species are at risk due to factors such as habitat loss, deforestation, and illegal harvesting. Conservation efforts are underway to protect and preserve these plants.
