Identification of these grasses/Sedges native to Maldives:
Need your help in identifying these three native grasses that grow in Maldives.
And It will be good to know if they can be used for cleaning water of Nirates, Nitrites, Phosphates and other impurities.
Will they work as an alternative to Vetiver and other reeds like Phragmites?
They are sedges/ rushes and ferns. No grass among these pictures.
