Abstract
Eriocaulon vandaanamense (Eriocaulaceae), a new species from a marshy coastal area in the Alappuzha District, Kerala, India, is described and illustrated. The new species is similar to E. truncatum and resembles it in having vertically elongated seed coat cells, but differs mainly in having pale black hoary floral bracts, 3-lobed hoary male sepals, linear-falcate, non-conduplicate hoary female sepals, and small, smooth, pale brown seeds without seed coat appendages.
