Abstract
A rare sedge, Rhynchospora submarginata Kuek., thought to be extinct from India, was rediscovered recently from the coastal belt of Kollam district in Kerala. It was last seen by Robert Wight from Kollam during 1866-1868 and then it was never collected again from the political boundary of Indian subcontinent. Its rediscovery is of great scientific interest especially as it shows disjunct distribution by occurring in Malaysia, Thailand and Australia apart from India.
