What has happened?

Indian researchers have discovered the world’s smallest land fern hiding in the Ahwa forests of the Western Ghats in Gujarat’s Dang district. The fingernail-sized fern belongs to a group known as the adder’s-tongue ferns, named after their resemblance to a snake’s tongue

Unique features

• A look at the plant’s minuscule seeds (called spores) under a powerful electron microscope revealed it had a unique thick outer layer which similar species lacked
• The plant’s DNA was also found to vary enough from its relatives to call it a new species
• Size: 1 cm
