Botanists have described Leucas droupadiae, a previously unknown plant of the mint family (Lamiaceae), from coastal sand dunes in the Cuddalore district of Tamil Nadu on the Coromandel Coast.
The description was published on 7 August 2026 in the plant-taxonomy journal Phytotaxa, volume 769, by Sugaseelan Akash, Kathavarayan Manikandan, Selvam Srikanth and Authinarayanan Rajesh.
The species is an erect, unbranched herb about 15 cm tall that anchors itself in loose sand with a shallow web of fibrous roots instead of a deep taproot.
Its most distinctive feature is its fruit: oblong nutlets that are golden yellow with irregular dark brown spots, unlike those of its closest relatives.
Because of its very limited known range it has been provisionally assessed as Data Deficient, and it is named in honour of President Droupadi Murmu.
Data Deficient is not a measure of how safe a species is — it is a statement about the evidence. A species is placed here when it has been looked at, but there is not enough information on its distribution or population to judge its risk of extinction. It is therefore different from Not Evaluated, where no assessment has been attempted at all, and different from Least Concern, which is a positive finding of low risk. Newly described species with a single known locality, like Leucas droupadiae, very often start here until surveys establish how widely they occur. Practically, Data Deficient species are easy to lose, because nothing triggers legal protection while the evidence is missing.
Simple Analogy: It is the biological equivalent of a verdict of 'insufficient evidence' rather than an acquittal — the case has been heard, but nothing has been proved either way.
Zoological Survey of India scientists earlier named a new head-shield sea slug Melanochlamys droupadi in her honour — a useful pair to remember together for prelims.

The species is known from coastal sand dunes in Cuddalore district on the Tamil Nadu coast, part of the Coromandel Coast fronting the Bay of Bengal.
