plant with very long thin
leaf-stalks and spear shaped leaf blades. It flowers if left to grow
through the surface and plantlets are formed on the flower stalks like the
other species of Echinodorus. Flowers are white, 3-petalled, and grow in
distant whorls on a rigid long stem. Mexican Sword-Plant is native to
Brazil and Mexico.
