Scientists from the Botanical Survey of India have discovered a new species of moss from the misty, high-altitude forests of the Western Himalayas. Named Indopottia himalayensis, the green plant was discovered during a recent field expedition in Uttarakhand, and is only the third species of its kind ever identified globally. The researchers spotted the intriguing specimen while conducting a comprehensive plant-life survey of the Garhwal Region. While trekking through the shady, evergreen forests of the Madhyamaheshwar area at an elevation of nearly 1,900 metres, the researchers found the moss clinging to a thin layer of moist soil draped over a rock.

Indopottia himalayensis physically and ecologically differs from its only two known cousins, which reside far away in the Western Ghats of southern India and the mountains of  Thailand. While its relatives typically grow on tree bark or decaying wood, this newly discovered moss is entirely terrestrial, thriving directly on soil-covered rocks. Under the microscope, the researchers noted several unique physical traits that set it apart. It grows slightly taller than its Thai counterpart, reaching up to 13 millimetres in length, and features a perfectly rounded stem. Unlike the southern Indian species, which produces spore-capsules in pairs that droop downwards, the new Himalayan moss produces a single, upright, cylindrical spore-capsule. This capsule features a distinctive lid that bends sideways when dry, and its leaves lack the specific patch of transparent, bulging cells found in its closest relatives.

The research team chose the name Indopottia himalayensis as a tribute to the magnificent Himalayan mountain range, where the type specimens were unearthed. Beyond adding a new entry to biology, this discovery could also reveal more about Earth's geological history. Finding this specific genus in the Himalayas bridges a massive geographical gap between southern India and Southeast Asia. Scientists believe this tiny plant's distribution supports the theory of a Himalayan corridor, an ancient biological highway that formed millions of years ago after the Indian and Eurasian tectonic plates violently collided, allowing ancient plant and animal life to migrate and spread across the newly connected Asian continent.
