Abstract
Fimbristylis agasthyamalaensis, a new species belonging to section Fuscae from Western Ghats, India is described and illustrated with photographs. The species shows some morphological similarities with F. onchnidiocarpa, but differs in having three stamens, larger anthers, 1–3 slightly twisted spikelets, smaller involucral bracts and obconical nutlets with cupular stipe. Its distribution, ecology and conservation status are also discussed.
