Fimbristylis agasthyamalaensis: New plant species discovered in Western Ghats
Researchers have discovered new grass-like plant species named Fimbristylis agasthyamalaensis in Ponmudi hills within the Agasthyamala Biosphere Reserve in the Western Ghats biodiversity hotspot. It has been classified as sedge, the grass-like plant and has been named after the locality from which it was found.
The new species of plant belongs to the Cyperaceae family. Its flowering and fruiting were observed from October to March. In India, Cyperaceae genus is represented by 122 species, of which 87 are reported from the Western Ghats. Many of the known Cyperaceae species are medicinal plants or used as fodder.
Fimbristylis agasthyamalaensis is highly prone to wild grazing. It is also subject to anthropogenic pressures as its habitat falls within tourism spot and perimeter of place of worship that could lead to its extinction in absence of scientific conservation. Researchers have recommended preliminary conservation assessment of plant as ‘critically endangered,’ according to IUCN criteria.
