An occasional plant of ponds, ditches and other shallow waters throughout much of Florida. The range includes the southeastern coastal states from Mississippi into North Carolina.
The small white three-petaled flowers are 1.3cm (~1/2 in.) or less in diameter. The racemes reach above the water in one to five whorls of flowers on spreading pedicels. The flattened grass-like leaves may be completely below the water (submersed) or extending above the water surface (emersed) like the flowers. Leaves are 4-40cm (~1-1/2 to 15-3/4 in.) long and up to 0.5cm (2/10 in.) wide.
Like all members of the Sagittaria genus, the flowers are unisexual, with the male flowers appearing higher on the raceme above the female flowers.
Sagittaria isoetiformis is a member of the Alismataceae - Water-plantain family.
