Eriocaulon quinquangulare is a spectacular, still very rare Eriocaulon species. With its exotic look and red leaf bases it resembles some bromeliads. It was already introduced under trade names such as Eriocaulon sp Quinquangular "Red" and is produced in nurseries as emersed (terrestrial) plant. Eriocaulon quinquangulare is distributed in tropical Asia from Pakistan to Vietnam and occurs in moist places.
As aquarium plant, this species needs very much light, a nutrient-rich substrate and CO2 supply. It looks best as specimen plant or in a small group in the midground. Also for paludariums and ripariums E. quinquangulare is surely an enrichment, the more so as it grows quite easily as emersed plant.
The plants came in excellent condition and person communicating with me was very freindly and helpful
