Six subtropical weeds of the Cyperaceae family (Bulbostylis thouarsii, Cyperus compressus, C. distans, C. iria, C. pumilus and Fimbristylis dichotoma) are reliably reported for the first time from Spain (and probably from Europe as well). All were found in a municipal nursery near Valencia, destined for the restoration of natural habitats, and have probably been introduced, inadvertently, with coconut fiber from tropical Asia (possibly Sri Lanka). These species are briefly characterized and their weed status in the world is assessed. To prevent a future naturalization eradication of these weeds is recommended.
